Method for transformer substation telecontrol device and regulation and control master station remote signaling automatic closed-loop joint debugging

Abstract

The present invention relates to a method for transformer substation telecontrol device and regulation and control master station remote signaling automatic closed-loop joint debugging. A transformer substation monitoring background real-time database is taken as correct standard basis, EXCEL model telecontrol file published by the regulation and control master station is taken as joint debugging task guidance, and newly developed automatic closed-loop joint debugging software based on the IEC61850 protocol is employed to lead in the transformer substation monitoring background SCD configuration file to simulate telecontrol data and send the telecontrol data to the transformer substation background and the telecontrol device step by step. The transformer substation monitoring background receives the simulated telecontrol data and returns the telecontrol data of the monitoring background real-time database back to the automatic closed-loop joint debugging software based on the IEC61850 protocol; the regulation and control master station receives the telecontrol message of the telecontrol device and performs analysis, and returns real-time database telecontrol data of the regulation and control master station back to the automatic closed-loop joint debugging software based on the IEC61850 protocol to automatically compare the telecontrol data of the regulation and control master station and the transformer substation monitoring background. The correction rate of the method can reach 100%, the time saving rate of the method can reach more than 95%, the work efficiency is greatly improved, and the reliable and safe operation of the power grid is ensured.

Description

technical field [0001] The invention relates to the technical field of electric power system automation, in particular to a method for remote signal automatic closed-loop joint debugging of a substation telecontrol device and a control master station. Background technique [0002] With the deepening application of power regulation integration, the central role of the provincial (regional) regulation master station is increasing day by day, and it has been responsible for the signal monitoring of the health status of all primary and secondary equipment in substations. The remote control device of the substation is a bridge connecting the first and second equipment status signals (referred to as "remote signal") in the substation to the remote control master station. The correctness of remote signal data between the remote control device and the control master station directly affects the safe operation of power grid equipment. [0003] The existing substation telecontrol devi...

AI Technical Summary

Problems solved by technology

The joint commissioning of the substation movement device and the control master station is still a manual method, and the amount of information in the substation is huge (a 500kV substation based on the IEC61850 protocol has about 10,000 pieces of information). Manually use the SCD file of the monitoring background to simulate the remote signal trigger of the secondary equipment. It is necessary to search and locate items one by one, and assign values ​​​​one by one to send, which is extremely low in work efficiency and the accuracy rate of joint debugging is not high

[0006] 2) Affect the reliability of power system operation

The SCD configuration file of the substation monitoring background is not the real-time running database of the monitoring background. The SCD file and the monitoring background database are manually configured by the manufacturer, and the two may be misplaced. Carefully check the monitoring background data again, resulting in hidden errors that are not easy to be found
