Abstract

The invention provides an AC synchronous electric energy metering system based on the Beidou / GPS clock, which is mainly composed of a synchronous AC concentrator based on the Beidou / GPS module clock and a synchronous AC electric energy meter based on the Beidou / GPS module clock; the synchronous AC centralized The main function of the device is to realize the clock synchronous electric energy metering of the AC distribution network station area, and simultaneously collect the electric energy metering data of all synchronous AC electric energy meters in the AC distribution network station area; the main function of the synchronous AC electric energy meter is clock synchronous electric energy metering and Communication function with synchronous AC concentrator. The invention realizes the accurate clock synchronous AC power metering function, solves the problem that conventional metering devices cannot measure synchronously, provides a device basis for demand response electric energy metering, and also realizes the online detection function of the metering accuracy of user electric energy meters.

Description

technical field [0001] The invention relates to the technical field of electric energy metering, in particular to AC synchronous electric energy metering. Background technique [0002] Under the background of vigorously promoting the reform of the power sales side in my country, the power reform will form a multi-link market for power generation companies, multiple power sales companies, power grid companies and power users, strengthen the integration of demand-side response technology and the power sales side market, and form supply and demand interactions. , A good atmosphere of interconnection requires a more accurate clock power metering device to ensure the accuracy of power metering in the period corresponding to the actual demand and meet the requirements of real-time demand response. [0003] Accurate real-time, time-based energy metering system is the basis for implementing price incentive measures for power demand side response, so as to realize accurate measurement...
