    FIELD OF THE INVENTION
    [001] The present invention generally relates to methods, devices and systems and, more particularly, to realizations of methods, devices and phase identification systems for a measured. BACKGROUND OF THE INVENTION
    [002] In many cases, utility providers wish to communicate electronically with utility meters for numerous purposes that include disconnecting or scheduled connection of utility services to measured loads, automatic meter reading (AMR), load reduction and load control, automatic distribution and smart grid applications, interruption reporting, providing additional services such as Internet, video and audio, etc. In many of these cases, to perform these functions, meters need to be configured to communicate with one or more computing devices over a communications network, which can be wired, wireless, or a combination of wired and wireless, as known to a person skilled in the art.
    [003] In many cases, such meters are also equipped with an electromechanical switch that can be operated remotely to perform functions, such as disconnecting or connecting utility services to measured loads, load reduction and load control, and the like . However, in many cases, the public utility also wants to know which phase or phases of a multiphase electrical system the load is connected to, or which phase or phases a load control relay is connected to. A challenge faced by utilities is the fact that records are incomplete or inaccurate that indicate to a smart meter installer which phase an individual customer is connected to. Therefore, in order to accurately identify the current phase of a branch of the private feeder, employees of the utility need to physically follow a cable back through several distribution facilities until it reaches a point in the distribution network at which phase is definitely known. This can be a very labor-intensive and time-consuming process, which can often lead to incorrect information. During storms or emergencies, this can also lead to safety problems. When a utility performs several operations, such as defining the load profile, analyzing the power quality, loading each phase, planning the distribution system, and the like, it is important to know which phase or phases the smart meters are connected to, so that the analysis can be done in relation to each phase.
    [004] Therefore, systems and methods that provide the phase identification of a smart meter that overcomes the challenges present in the technique, of which some are described above, are desired. DESCRIPTION OF THE INVENTION
    [005] The realizations of methods, devices and systems for the phase identification of a smart meter are described in this document.
    [006] One aspect comprises a method of phase identification for a smart meter. An embodiment of the method comprises connecting a device to at least one first phase of a multiphase electrical system; measure at least the first phase of the polyphasic electrical system to which the device is connected, for electrical consumption information using a smart meter; store a first phase identifier for the first phase of the multiphase electrical system to which the device is connected, in a memory associated with the smart meter; and transmitting at least the first phase identifier over a network operably connected to the smart meter.
    [007] Another aspect comprises a smart meter. An embodiment of the smart meter comprises one or more switches, measurement components, a memory, at least one network interface, and a processor. The one or more switches can be used to connect a device to at least one first phase of a multiphase electrical system. The measurement components can be used to measure at least the first phase of the multiphase electrical system to which the device is connected, for electrical consumption information. The processor is operably connected with one or more switches, the measurement components, the memory and at least one network interface. The processor is configured to: store a first phase identifier for the first phase of the multiphase electrical system to which the device is connected, in memory; and retrieve the first phase identifier for the first phase of the multiphase electrical system to which the device is connected, from memory and transmit at least the first phase identifier over a network operably connected with the smart meter using the network interface.
    [008] In yet another aspect, a system is described. An embodiment of the system comprises a computing device, a network operably connected to the computing device and a smart meter operably connected to the network. In one aspect, the smart meter comprises one or more switches, measurement components, a memory, at least one network interface and a processor. The one or more switches can be used to connect a device to at least one first phase of a multiphase electrical system. The measurement components can be used to measure at least the first phase of the multiphase electrical system to which the device is connected, for electrical consumption information. The processor is operably connected with one or more switches, the measurement components, the memory and at least one network interface. The processor is configured to: store a first phase identifier for the first phase of the multiphase electrical system to which the device is connected, in memory; and retrieve the first phase identifier for the first phase of the multiphase electrical system, to which the device is connected, from memory and transmit at least the first phase identifier over a network operably connected with the smart meter using the network interface.

In this way, there are a variety of additional steps that can be performed, it is understood that each of these additional steps can be performed with any specific realization or combination of realizations of the presented methods.
    [016] The present methods and systems can be more readily understood by reference to the following detailed description of the preferred embodiments and the examples included therein and to the figures and their previous and next description.
    [017] With reference to Figure 1A, an illustration is provided of a type of system that would benefit from the achievements of the present invention. Figure 1A is a single-line block diagram of a section of an exemplary utility distribution system, such as, for example, an electrical distribution system. As shown in Figure 1A, a utility is distributed by a utility provider 100 to several L1-Ln 102 loads through a distribution system 104. In one aspect, the utility provided may consist of electricity . Although shown in Figure 1A as a single line diagram, it should be noted that the distribution system 104 can comprise single phase and / or polyphasic components and be of varying voltage levels. Consumption and demand for loads 102 can be measured at the load sites by the M1-Mn 106 meters. If an electric meter, 106 meters can consist of single-phase or multi-phase electric meters, as known to a person skilled in the art, depending on load 102. For example, the load can be single-phase and therefore meter 106 can be single-phase. Single-phase loads can be connected to different phases (for example, phase A, phase B or phase C) of the distribution system 104. Similarly, for example, load 102 can consist of a multi-phase load, such as a three-phase load , and meter 106 may consist of a three-phase meter that measures the three phases that serve load 102.
    [018] In one aspect, the electrical meter 106 consists of an intelligent meter, as described in this document and as known to a person skilled in the art. Later in this document, the specification will refer to meter 106 as a "meter", "electric meter" and / or "smart meter", where the terms can be used interchangeably. A non-limiting example of a smart meter is the GE I210 + c meter, as available from the General Electric Company (“GE”) (Schenectady, NY). Another non-limiting example of a smart meter is the GE SM3000 meter, as also available from GE. Although consumption or demand information is used by the utility 100 primarily for consumer billing, it can also be used for other purposes that include planning and profiling the utility distribution system. In some cases, utility providers 100 wish to communicate electronically with meters 106 for a variety of purposes including disconnecting or programmed connection of utility services to loads 102, automatic meter reading (AMR), load reduction and control of loads. load, automatic distribution and smart grid applications, interruption reporting, provision of additional services such as Internet, video and audio, etc. In many of these cases, meters 106 need to be configured to communicate with one or more computing devices 108 over a communications network 110, which can be wired, wireless, or a combination of wired and wireless, as required. known to a technician in the subject. In one aspect, network 110 consists of an advanced measurement infrastructure (AMI) network. AMI refers to systems that measure, collect and analyze energy usage, and interact with advanced devices, such as electricity meters, gas meters, water meters, and the like, through a variety of on-demand media (under demand) or predefined schedules. This infrastructure includes hardware, software, communications, controllers and consumer power display devices, customer associated systems, meter data management (MDM) software, network and supplier distribution business systems, and the like. The network 110 between measurement devices (e.g. 106 meters) and business systems allows for the collection and distribution of information to customers, suppliers, utilities and service providers. This makes it possible for these businesses to participate in or provide products, services and demand response solutions. By providing information to customers, the system assists a change in energy consumption from its normal consumption patterns, in response to price changes or as incentives designed to stimulate lower energy consumption during periods of peak demand or higher wholesale prices or during periods of low operating system reliability. In one aspect, network 110 comprises at least part of a partially interconnected intelligent network. In one aspect, network 110 uses one or more of a WPAN (for example, ZigBee, Bluetooth), LAN / WLAN (for example, 802.11n, microwave, laser, etc.), WMAN (for example, WiMAX, etc.), WAN / WWAN (e.g. UMTS, GPRS, EDGE, CDMA, GSM, CDPD, Mobitex, HSDPA, HSUPA, 3G, etc.), RS232, USB, Firewire, Ethernet, USB wireless, cellular, OpenHAN , power line carrier (PLC), broadband power lines (GLP), and the like. Such meters 106 can be equipped with one or more switches that can be used to remotely connect or disconnect the released service or product.
    [019] For example, in some cases, an electrical distribution system 104 may consist of a multi-phase system, such as a three-phase four-wire network, which supplies power with the use of energy. Each of the feeder lines then branches into multiple circuits to supply a plurality of local transformers mounted on a pole or pedestal type, which reduces the voltage to the final voltages of, for example, 120 or 240 volts per phase for distribution and measurement at the customer's commercial and residential locations. Generally, residential customers can be connected to any one phase of the three-phase system with the use of a single-phase meter and commercial customers can be connected to all three phases using the three-phase meter with a load control relay ( “LCR”) connected in any of the phases. When a utility performs several operations, such as defining the load profile, analyzing the power quality, loading each phase, etc., you want to know which phase the smart meter is connected in so that the analysis can be carried out. performed for each phase. Such a system, as described above, is illustrated in Figure 1B. Figure 1B is an exemplary illustration of a three-wire, four-wire distribution system (phases A, B, C and neutral, N) 104 in accordance with an embodiment of the present invention. As shown in Figure 4B, the distribution system 104 comprises three-phase conductors (phases A, B and C) and a neutral wire. In one aspect, each of the three phases and the neutral are provided for each meter 106. In one aspect, the voltage supplied at meters 106 is decreased by a transformer 114 at a level that can be used by load 102 (for example, 120 / 240, 277/480, and the like). Transformer 114 can consist of two or three single-phase transformers, or a single three-phase transformer. In one aspect, load 102 can be single phase and meter 106 can be configured to switch between phases A, B and C to serve load 102 or to disconnect load 102 from electrical service. In one aspect, this switching can be performed manually. In another aspect, this switching can be performed automatically and remotely. In another aspect, load 102 can be three-phase and can be measured by a three-phase meter 106. In one aspect, the three-phase meter can comprise a load control relay (LCR) 112. In one aspect, the three-phase meter 106 can be configured to switch between phases A, B and C to serve LCR 112, or to disconnect LCR 112 from electrical service. In one aspect, this switching can be performed manually. In another aspect, this switching can be performed automatically and remotely. In order to balance the load at each stage of the distribution system 104 and perform other utility functions and analysis, one wishes to know the phase in which a load 102 is connected or the phase in which an LCR 112 is connected.
    [020] The methods, systems and devices for determining the phase to which the meter is connected, in the case of a single phase meter, and the phase to which an LCR is connected, in the case of a multi-phase meter, are desired. Therefore, it is desired that the meters 106 of a system, such as the one shown in Figures 1A and 1B, are configured to have capacities beyond that of measuring utility consumption. The achievements of the methods, devices and systems for phase identification in a smart meter are described in this document. In one aspect, a field for the phase identification is maintained in a smart meter memory. The phase identifier can be read or written (depending on security) by a public utility using advanced communication techniques, such as AMI, optics, RF, WiMax, LAN / WAN, GSM, etc., and meter software (for example, GE Meter Mate ™ software). In the case of a single-phase meter, this field can represent the phase to which the main relay is connected and in the case of a multi-phase meter (for example, three-phase), this field can represent the phase to which an LCR is connected. In one aspect, the phase identification field can be configured to update automatically. For example, if a meter is configured in such a way that it can switch the phase that serves the load (and that is being measured), then that meter can be configured to automatically populate the phase identifier field with the phase at which the load is connected. Such a meter that can switch the phases is described in United States patent application no. serial 12 / 987,301 by Pamulaparthy, filed on January 10, 2011, which is incorporated herein by reference and becomes a part of it. In another aspect, the phase identification field can be provided over the network to the meter if an entire feeder has been switched using, for example, automated distribution switches as part of a smart grid deployment. In another aspect, the phase identification field can be stored manually whenever the phase configuration, as mentioned above, is changed for a particular meter. For example, in the automatic population of the phase identifier field, upon receipt of a command for phase switching (for example, from phase A to phase B), the phase to which the meter is currently connected is read (phase A) and a relay will be switched to phase B and the phase identifier field will be updated from phase A to phase B. In the manual case, for example, if a utility person changes the meter connection or LCR from one stage to another, the individual can record the field (assuming the individual has security access) using the software (for example, GE Meter Mate ™ software) and any of the media, such as such as AMI, optics, RF, WiMax, LAN / WAN, GSM, etc. Phase change events can be recorded in an event log kept on either or both the meter and computing device 108 for future reference.
    [021] Figure 2 illustrates a block diagram of the overview of a non-limiting realization of a 106 meter that can be used to practice the realizations of the present invention. In this exemplary realization, the utility consists of polyphasic electrical energy. In particular, in Figure 2, the electrical service consists of three-phase, four-wire electrical energy that generally comprises three-phase conductors 202, each carrying voltage and electrical current that is generally displaced from each other by 120 degrees (for example, phases A , B and C) and a separate neutral wire 214. It should be noted, however, that the embodiments of the invention can be used with single-phase and multi-phase electrical systems, such as two-phase, three-phase, four-phase, etc. It is further understood that the realization of a meter 106 shown in Figure 2 consists of a switch 204. Switch 204, although shown as a three pole and one position switch, may consist of a single switch or any combination of multiple switches. poles or unipolar that provide a means to selectively switch the power supply 104 that provides electrical service among the plurality of phase 202 conductors (for example, phases A, B or C), or to disconnect the load 102 from the electrical service . In this way, load 102 can be provided with single-phase electrical service from any one of a plurality of phases. It should also be noted that such meter 106 can be configured to switch between two, three, four, five, etc., phases, and is not limited to just a three-phase configuration to provide single phase service for load 102. In In one aspect, switch 204 can be controlled by a control mechanism 212 that actuates switch 204 (i.e., causes it to switch from one phase to another or disconnect the load). Control mechanism 212 receives a control signal from meter 206 electronics. In addition, in one aspect, control mechanism 212 can provide a feedback signal to meter 206 electronics that indicates the position of switch 204. In in other words, the control mechanism 212 can inform the meter electronics if the single phase electrical service from phase A, phase B, phase C, etc. is being provided for load 102, or if load 102 is disconnected electrical service.
    [022] Analog voltage and current inputs are also provided for measurement electronics 206. In one aspect, analog signals are derived from the electrical power supply 104 that serves load 102 and that which is measured by meter 106 In another aspect, analog signals are derived from a separate electrical source. In one aspect, the analog voltage signal can be provided by one or more potential transformers (PT) 208, if necessary, although other means, such as a voltage divider, capacitive coupling, or the like, can be used. If the voltage level of the source is low enough (for example, .25 volts AC, or less), then a PT 208 or other means of decreasing or transforming the voltage can be omitted. Similarly, in one aspect, the analog current signal can be provided by one or more current transformers (CT) 210. In one aspect, the one or more CTs 210 can have a 1: 2500 turn ratio. In one aspect, one or more resistors (not shown) can be used to convert the current signal from the CT 210 to a voltage signal.
    [023] In one aspect, the electronics of the 206 meter can comprise a memory (not shown in Figure 2). The memory can be used to store a phase identifier that indicates the phase of the multiphase electrical system to which load 102 (and meter 106) is connected. For example, if switch 204 is configured in such a way that the power supply 104 that serves load 102 and that being measured by meter 106 consists of phase A, then the phase identifier stored in memory indicates phase A. Similarly, if switch 204 switches from phase A to phase B, then the phase identifier stored in memory is updated to indicate phase B. In one aspect, the phase identifier is automatically stored when the power supply 104 is switched from one phase to another (for example, from phase A to phase B). For example, control mechanism 212 can provide a signal that indicates the phase in which load 102 is connected. In a non-limiting example, a signal can be sent to meter 106 over a network 110. In one aspect, network 110 consists of an advanced measurement infrastructure (AMI) network. The signal can consist of a command to switch the phases to which the load is connected from a first phase (for example, phase A) to a second phase (for example, phase B), or to disconnect the load 102. The The command is received by a processor (not shown in Figure 2) in the meter electronics 206, which causes the control mechanism 212 to switch the connection from phase A to phase B. The phase identifier in memory is, then updated to reflect that load 102 and meter 106 are now connected to phase B. In another aspect, the phase identifier can be stored on meter 106 manually by a user who is authorized to write to memory using, for example, near-field infrared communications, such as BlueTooth, Wi-Fi, RF, RFID, and the like, or by connecting a device, such as a computer, to meter 106 using a bus connection. In another aspect, the phase identifier can be communicated to memory in the electronics of meter 206 through a network 110 that is operably connected to the electronics of meter 206. In one aspect, network 110 consists of an infrastructure network of advanced measurement (AMI). For example, if an entire circuit is switched, automatically or manually, by a utility in such a way that phase A becomes phase B or some other similar switching, then a signal can be sent to the meter electronics 206 on the network to update the phase identifier in such a way as to indicate that meter 206 and load 102 are connected to phase B. Since the phase identifier is stored in memory, it can be transmitted over network 110 to, for example , computing device 108 or can be read from memory by a user with appropriate authorization and equipment.
    [024] In one aspect, electronics 206 comprises at least one memory, and one or more processors, and provides an interface for receiving a signal from network 110 and causing switch 204 to act through control mechanism 212 The electronics memory of the 206 meter can be used to store a phase identifier as described above. The electronics of meter 206 may comprise a transmitter that can be used to transmit at least the phase identifier over network 110 to a separate computing device 108. In one aspect, the electronics of meter 206 may comprise one or more measurement microcontrollers which include a Teridian 6533 controller or a Teridian 6521 controller, as available from Maxim Integrated Products, Inc. (Sunnyvale, California), among others. In one aspect, the one or more processors can perform measurement functions, such as determining the number of kilowatt hours (KWH) of electricity consumed by the load 102.
    [025] In one aspect, the one or more processors of the 206 meter electronics can be configured to store a first phase identifier for the first phase of the multiphase electrical system, to which load 102 is connected, in memory. Then, when requested, the processor can retrieve the first phase identifier for the first phase of the multiphase electrical system, to which the device is connected, from the memory and transmit at least the first phase identifier to computing device 108 on the network 110 operably connected with the smart meter 106 using the network interface. In one aspect, network 110 consists of an advanced measurement infrastructure (AMI) network. In one aspect, switch 204 can be used to switch load 102 such that the load is connected to at least one second phase of the multiphase electrical system, so that the measuring components measure at least the second phase of the electrical system polyphasic, to which load 102 is connected, for electrical consumption information using the smart meter 102. The one or more processors are additionally configured to store a second phase identifier for the second phase of the polyphasic electrical system, which the load 102 is connected, in the memory associated with smart meter 106. The one or more processors are also configured to retrieve the second phase identifier for the second phase of the multiphase electrical system, to which load 102 is connected, from memory and transmit at least the second phase identifier to computing device 108 over network 110 operably connected with smart meter 106 with the using the network interface. In one aspect, switch 204 consists of an automatic switch controlled by the processor and the switching of load 102 in such a way that load 102 is connected to at least the second phase of the multi-phase electrical system comprises automatically switching load 102 from the first phase to the second phase of the multi-phase electrical system using switch 204. In one aspect, the one or more processors are operably connected to switch 204, such that the storage of the second phase identifier for the second phase of the polyphasic electrical system, to which the load 102 is connected, in the memory associated with the smart meter 106 comprises automatically storing the second phase identifier in memory when the device is switched from the first phase to the second phase of the polyphasic electrical system.
    [026] Figure 3 illustrates an embodiment of a meter 106 used to measure a polyphasic electrical service 104 that serves a load 102. In this embodiment, the polyphasic electrical service 104 consists of a three-phase service comprising conductors from phase 202 to phase A, phase B and phase C, and a neutral wire 214. In other embodiments, there may be more or less electrical phases and phase conductors. In the embodiment shown in Figure 3, switch 204 is used to supply electrical power to a load control relay (LCR) 302. The LCR can be used to turn selected loads on or off using meter 106. For example, the LCR can be used to turn the power on or off for a water heater, pump or pool heater, air conditioning equipment, etc. In one aspect, the LCR 302 can have a 40 amp rating. In another aspect, the LCR 302 can have a two amp rating. In one aspect, LCR 302 can receive control signals from meter 206 electronics. In another aspect, LCR 302 can receive external control signals from meter 106. For example, LCR 302 can receive signal without wire that causes the LCR 302 to open or close. As shown in Figure 3, switch 204 can be used to connect the LCR to one of phases A, B or C, or to disconnect all. Although shown as a three pole and one position switch, switch 204 may consist of a single switch or a plurality of switches having any number of positions and / or poles. Similar as described in reference to Figure 2, the control mechanism 212 of Figure 3 is used to actuate switch 204 (i.e., to cause it to switch from one phase to another or to disconnect LCR 302). Control mechanism 212 receives a control signal from meter 206 electronics. In addition, in one aspect, control mechanism 212 can provide a feedback signal to meter 206 electronics that indicates the position of switch 204. In In other words, the control mechanism 212 can inform the meter electronics if LCR 302 is being provided with single phase electrical service from phase A, phase B, phase C, etc., or if LCR 302 is disconnected from the electrical service.
    [027] In one aspect, the electronics of the 206 meter can comprise a memory (not shown in Figure 3). The memory can be used to store a phase identifier that indicates the phase of the multiphase electrical system to which the LCR 302 is connected. For example, if switch 204 is configured in such a way that the phase serving LCR 302 is phase A, then the phase identifier stored in memory indicates phase A. Similarly, if switch 204 switches from phase A for phase B, then the phase identifier stored in memory indicates phase B. In one aspect, the phase identifier is automatically stored when the LCR 302 is switched from one phase to another (for example, from from phase A to phase B). For example, control mechanism 212 can provide a signal that indicates the phase to which LCR 302 is connected. In a non-limiting example, a signal can be sent to meter 106 over a network 110.
