Research on remote calibration and online monitoring system of electric energy metering device

Abstract

This paper introduced research on remote calibration and online monitoring system of the gateway electric energy metering device. The function combined with composition of the station's remote calibration-monitoring device and the master station management platform are emphasized. The system integrated the ways of multi-channel synchronous remote calibration, multi-dimensional monitoring, intelligent switching of detection and calibration loop, self-test of detection unit and so on into the complete set, cooperated with the master station management platform, to realize remote calibration, online monitoring, fault diagnosis and state evaluation of the gateway electric energy metering device. The system innovatively adopts a multi-channel synchronous remote calibration method to realize intelligent switching of detection and calibration loops. Through multi-dimensional data detection and state evaluation algorithms, it is possible to more comprehensively detect device status and achieve fault diagnosis. In addition, the system has high stability, accuracy and flexibility. The research plays an important role in reducing the operation-maintenance costs of the gateway electric energy metering device, guaranteeing the safety of operators and improving the level of operation and management, which ensures the accuracy of gateway energy metering and the fairness of both parties in power trade.
