Multi-phase electric energy meter, counting method thereof and computer readable storage medium

Abstract

The invention discloses a multiphase electric energy meter, a counting method thereof and a computer readable storage medium, and relates to the field of electric energy meters, and the counting method comprises the steps: obtaining a plurality of pulse interruptions transmitted by an external metering unit in a first time period; according to the multiple pulse interruptions, the number of active pulses, the number of reactive pulses and the number of apparent pulses are obtained through calculation; according to a power integral weight obtained by the external metering unit in a first time period, classifying the active pulse number, the reactive pulse number and the apparent pulse number according to phases of a preset phase information set to obtain a pulse distribution result; according to the pulse distribution result, active electric energy, reactive electric energy and apparent electric energy corresponding to the phase information set are obtained through calculation. Various types of electric energy calculation can be carried out internally through the pulse number, frequent access with an external metering unit is not needed, and loss of electric energy counting is reduced.

Description

technical field [0001] The present application relates to the technical field of electric energy meters, in particular to a polyphase electric energy meter, a counting method thereof, and a computer-readable storage medium. Background technique [0002] Three-phase alternating current is a form of transmission of electric energy, referred to as three-phase electric, which is composed of three alternating current potentials with the same frequency, equal amplitude, and 120° phase difference. Polyphase watt-hour meters are used to measure the power consumption of three-phase alternating current. With the continuous development of the power industry, the market has more and more clear requirements for multi-phase watt-hour meter measurement algorithms, and the measurement scenarios are becoming more and more diverse; especially in the European market, The requirements for the energy meter measurement algorithm are getting higher and higher. In recent years, Europe has put forw...

Problems solved by technology

[0003] In the existing electric energy counting method, the central control unit of the electric energy meter is connected with the external metering unit through a communication bus. Acquisition of the metering unit, multiple and frequent acquisition processes, can easily lead to power loss, and the lost amount may continue to accumulate, or when the power meter is powered off, it needs to be powered by an internal battery so that the power information can be obtained from the external metering unit through the communication bus , affecting the life of the battery, and at the same time, when the battery is low, it also affects the work of the electric energy meter, resulting in the loss of electric energy counting
