An intelligent substation auxiliary point-to-point test method and system for full-link information flow

Abstract

The invention relates to an intelligent substation auxiliary alignment test method and system of full-link information flow, comprising the following steps: step S1, a tester completes the ''four remote'' function check of secondary equipment and primary equipment in the substation subsystem test phase, and records the full-link information flow and the function point number of all ''four remote''functions of the point in the substation; Step S2, carrying out closed-loop test of the telemechanical device; 3, aft that closed loop t is completed, the tester reproduces the network behavior of the space layer equipment, and checks the correctness of the graphics, the pressing plate, the handle and the numerical value on the monitoring back table; Step S4: Test the dispatching master station.A true reproduction of the actual test process, The test method covers two links: subsystem commissioning and station system commissioning, And cross-cover two links, using the full-link information flow of the intelligent substation auxiliary point test system can achieve automation and intelligent testing of substation function, reduce human error in the test process, improve work efficiency, ensure the standardization and correctness of the test items.

Description

technical field [0001] The invention relates to the technical field of substation function verification, in particular to an intelligent substation auxiliary point-to-point test method and system for full-link information flow. Background technique [0002] At present, from installation and commissioning to commissioning and operation, substations need to go through station-side unit commissioning, sub-system commissioning, station system commissioning, and system commissioning. The function inspection of "four remotes" in the station is an important test in the debugging of the subsystem, which is often called "point-to-point in the station". The content of the inspection is the correctness of the information or control instructions issued by the source equipment to reflect the health status of the equipment, and the correctness of the transmission path of the information. After the commissioning personnel complete the sub-system commissioning, they will provide the point ...

AI Technical Summary

Problems solved by technology

This method only solves the problem of test automation in station system commissioning. Because it isolates the previous point-to-point process in the station, it only completes the "four remote" information confirmation from the substation end to the dispatching master station, and cannot determine the signal sent by the equipment simulator. The consistency of the signal sent by the source device makes it impossible to truly and completely replace the on-site manual point-to-point process
