An integrated test and detection device for power distribution automation

Abstract

The invention provides a distribution automation integrated test and detection device, which includes an integrated test command center and a plurality of mobile comprehensive test terminals, each mobile comprehensive test terminal includes a feeder automatic tester, and the feeder automatic tester is used to receive signals from Test the simulation data of the command center, then connect the same simulated current to the tested power distribution terminal and the tested switch respectively, connect the same simulated voltage to the tested power distribution terminal and the tested switch respectively, and receive the initial The feedback data from the tested power distribution terminal and the tested switch are fed back to the integrated test command center; the integrated test command center is used to simulate the normal operation state and fault state, and output the simulation data to the feeder automatic tester, The feedback data fed back from the feeder automatic tester is received to determine whether the requirements are met. The invention realizes the integration test of primary equipment (switch) and secondary equipment (power distribution terminal).

Description

technical field [0001] The invention relates to the field of distribution automation, in particular to a distribution automation integrated test and detection device. Background technique [0002] Feeder automation refers to the automation of feeder lines between substation outlets and user electrical equipment. Its content can be summarized into two aspects: one is user detection, data measurement and operation optimization under normal conditions; the other is faults under accident conditions Detection, fault isolation, transfer and restoration of power control. [0003] When conducting on-site testing of power distribution automation, it is necessary to detect the linkage between the corresponding primary equipment, secondary equipment, and remote equipment. Among them: the main test content of the primary equipment is the output accuracy and volt-ampere characteristics of PT, CT and other equipment when the power system fails; the main test content of the secondary equi...

AI Technical Summary

Problems solved by technology

[0005] The power supply for on-site testing is difficult to solve;

[0006] The integration test of primary equipment (switch) and secondary equipment (power distribution terminal) cannot be realized;

[0007] The linkage test of smart devices (power distribution terminals) between different locations cannot be done;

[0008] Communication support between different places depends on mobile phones, walkie-talkies, etc., which cannot guarantee the synchronization and real-time performance of the test
