In order to improve the accuracy of power consumption measurement error monitoring of intelligent metering device, a power consumption measurement error monitoring system of intelligent metering device based on data acquisition and return is designed. The system is divided into hardware design and software design. The hardware part consists of two parts: the sub station and the master station. The main station subsystem is the main station error monitoring machine, which mainly includes the main station working machine, peripheral equipment and other information equipment. The substation terminal is composed of power acquisition module, CT switching module and Pt switching module. Its main function is to realize the collection of power and energy meter information data of primary equipment. The software is mainly composed of communication network and database. The main station subsystem and the sub station subsystem realize the data information interaction during the data collection and return through the communication network, and set up the database server in the local terminal equipment and the measurement center respectively. The simulation results show that: the system performance indicators meet the requirements of power grid electricity metering regulations, can replace the manual field monitoring equipment, the error monitoring results are accurate and reliable, and the application effect is good.
