Abstract

The invention discloses a remote on-line detection system of an electric energy metering device. The system comprises a data server, a network switch, a terminal computer and a substation device, wherein the network switch is connected with the data server; the terminal computer is connected with the network switch; the substation device comprises a multi-channel on-site standard electric energy meter, a substation industrial personal computer and a human-computer interface; the substation industrial personal computer is connected with the multi-channel on-site standard electric energy meter; the human-computer interface is connected with the substation industrial personal computer; and the substation industrial personal computer is connected with the data server through a telecommunication channel. In the on-line detection system using the technical scheme, a voltage current transformer and secondary voltage drop are detected by a data comprehensive analysis method, so various indexes of the electric energy metering device can be comprehensively and remotely detected on line, the error of the electric energy meter is checked by using the multi-channel on-site standard electric energy meter, and the accuracy of on-site check and the reliability of a secondary loop are guaranteed.

Description

technical field [0001] The invention belongs to the calibration of electric variable measuring instruments, in particular to an online detection system for remote detection of electric energy metering devices at substation gateways. Background technique [0002] The complete substation electric energy metering device consists of electric energy meter, voltage transformer, current transformer, and secondary circuit. In order to ensure the accuracy of metering, the online detection system of the metering device has been used for real-time detection. However, the functions of this type of system are relatively Single, generally mainly to detect the error of the electric energy meter, but cannot reflect the operation of the voltage and current transformer, so that it cannot fully reflect the measurement accuracy of the metering device. Contents of the invention [0003] The purpose of the present invention is to provide a remote on-line detection system for electric energy met...
