Problems solved by technology

Therefore, the three-phase AC energy meter cannot be used as three independent single-phase AC energy meters, but can only be used as a single-phase AC energy meter.
However, in many large buildings, factories, base stations, etc., it is often necessary to separately measure and centrally manage a large amount

Abstract

The invention discloses a multi-path single-phase and three-phase mixed electric energy metering device. The electric energy metering device comprises three paths of independent three-phase electric energy metering modules, three paths of independent external monitoring voltage and current sampling modules, a microcontroller, a power source isolation protection module, a communication module, a memorizer, a real-time clock and a meter rectifying module. Parameters of each phase can be independently sampled. Each metering module comprises an electric energy register, the metering parameters of each phase of each metering module are transmitted to the microcontroller, and the microcontroller stores and uploads the single-phase and three-phase electric energy data.

Description

technical field [0001] The invention relates to an intelligent multi-channel electric energy metering device and method, in particular to a single-phase and three-phase compatible electric energy metering device and method. Background technique [0002] With people's emphasis on energy demand, electric energy has undoubtedly become the first of all energy sources, and smart grid has already become the development direction of electric power system. At present, both developed and developing countries are actively transforming traditional power grids into smart grids. Energy saving and environmental protection is a long-term major policy formulated and implemented in our country. Therefore, our country is vigorously developing smart grid construction. [0003] The widespread promotion of the smart grid is inseparable from the accurate measurement of various electric energy. The electric energy metering device is an electrical device that measures the electric energy consumed...
