Embodiment 1

[0046] see figure 1 , This embodiment provides an electric energy meter with functions of automatic identification of incorrect wiring and correct measurement functions, the electric energy meter is a three-phase smart electric energy meter. Wherein, the electric energy meter includes an acquisition module, a measurement module, an MCU main control module, an automatic error correction module and a communication module. Some of these modules can be integrated together to form a new module, can also be set independently, and can also be split into multiple sub-modules. Of course, the hardware of these modules can choose part of the hardware of the existing electric energy meter, and only need to upgrade the part of the existing hardware.

[0047] The acquisition module includes a three-phase voltage acquisition unit and a three-phase current acquisition unit. The three-phase voltage acquisition unit is used for collecting the three-phase voltage value and the three-phase volt...

Embodiment 2

[0095] This embodiment provides a control method for an electric energy meter with the functions of automatic identification of incorrect wiring and correct measurement. The method is applied to the electric energy meter with functions of automatic identification of incorrect connection and correct measurement in Embodiment 1. Among them, the electric energy meter control method of this embodiment can be used as an upgrade program in the existing electric energy meter, and can also be set separately and detachably installed in the existing electric energy meter through other structures, such as integrated modules, controllers, etc. In the electric energy meter, this is similar to the existing electric energy meter carrier module, which can be set independently. Wherein, the electric energy meter control method includes the following steps.

[0096] (1) Collect the three-phase voltage value, three-phase voltage phase angle, three-phase current value and three-phase current phas...

Embodiment 3

[0106]This embodiment provides a control system for a three-phase smart electric energy meter, which can be applied as a product in the form of a module, which is similar to the existing electric energy meter carrier module. The control system is used to implement the electric energy meter control method with the functions of automatic identification of wrong wiring and correct measurement in Embodiment 2, and can be independent from the existing electric energy meter. The control system can also appear in the hardware form of the controller, so that in practical applications, the controller only needs to be installed on the main control board of the electric energy meter. The control system can also be integrated with the existing carrier module to form a new carrier module with control function and control the existing electric energy meter.

Abstract

The invention discloses an electric energy meter with false wiring automatic identification and correct metering functions and a method thereof. The electric energy meter comprises an acquisition module, a metering module, an MCU main control module and an automatic error correction module. The acquisition module acquires a three-phase voltage value, a phase angle, a three-phase current value anda phase angle of the electric energy meter, and the metering module forms a corresponding vector diagram. The MCU main control module judges whether a wiring error exists or not, if yes, whether a preset vector diagram example the same as the vector diagram exists or not is searched for in an error wiring database, if yes, the wiring error type corresponding to the vector diagram is obtained, anda correction instruction is issued according to the wiring error type. And the automatic error correction module judges wrong wiring as certain wrong wiring measurement according to the correction instruction, and performs measurement storage on possible correct measurement at the same time. According to the invention, wiring errors can be automatically detected and corrected, correct metering isstored in the meter for alternative use, the defect of electric quantity compensation calculation after an event is overcome, and accurate metering of electric quantity is ensured in real time.

Description

technical field [0001] The present invention relates to an electric energy meter in the technical field of intelligent electric energy meter measurement, in particular to an electric energy meter with functions of automatic identification of incorrect wiring and correct measurement, and also relates to the electric energy meter of the electric energy meter with functions of automatic identification of incorrect connection and correct measurement Control Method. Background technique [0002] Three-phase smart energy meters are widely used in civil and industrial use. As an energy meter used for energy trade settlement, whether it can be measured correctly is related to the interests of both parties in the electricity settlement. In addition to the accuracy level of the energy meter, the factors that affect the correct measurement of the energy meter are whether the wiring of the energy meter is correct. At present, the accuracy level of the electric energy meter in use is re...
