Automatic closed loop joint debugging method for telecontrol equipment and regulation and control main station of intelligent substation

Abstract

The invention relates to an automatic closed loop joint debugging method for telecontrol equipment and a regulation and control main station of an intelligent substation. According to the automatic closed loop joint debugging method, The correctly-debugged SCD configuration files from the monitoring background of the substation and the EXCEL model files issued by the regulation and control main station are taken as the standard basis data source; data source simulation generation software based on the existing IEC61850 protocol is adopted for simulating the operations of sending the telemetry and telecontrol data of the substation to the telecontrol equipment, obtaining messages which are sent to the regulation and control center from the telecontrol equipment, performing analyzing, comparing and the like on the messages, and realizing telemetry and telecontrol automatic closed loop joint debugging; and meanwhile, the software automatically simulates the operations of sending down the telecontrol instruction from the regulation and control center to the telecontrol equipment, obtaining the telecontrol data which is sent down to the substation from the telecontrol equipment, performing analyzing, comparing and the like on the messages, and realizing telecontrol automatic closed loop joint debugging. According to the automatic closed loop joint debugging method, the purpose of joint debugging of the telecontrol equipment and the regulation and control main station can be fulfilled without requiring power failure of primary and secondary equipment; the accuracy can achieve 100%; the time saving rate can reach greater than 95%; and therefore, the working efficiency is greatly improved, and the reliable and safe operation of the power grid can be ensured.

Description

technical field [0001] The invention relates to the technical field of power system automation, in particular to a method for automatic closed-loop joint debugging of an intelligent substation telecontrol device and a control master station based on the IEC61850 protocol. Background technique [0002] With the deepening application of unattended smart substations and the improvement of advanced functions of the control master station, the control master station is no longer just responsible for monitoring the position of the switch switch and the power flow of the line in the traditional sense, but has assumed all the primary and secondary tasks of the substation. Monitoring tasks such as monitoring of equipment health status, remote remote operation of primary and secondary equipment, etc. The telecontrol device of the substation plays a connecting role in the control master station. It is a bridge connecting the equipment in the station with the remote control master stati...

AI Technical Summary

Problems solved by technology

The joint commissioning of the substation telecontrol device and the control master station is still a manual method, with a large number of equipment (2 telecontrol devices and at least 4 control master stations), a large number of repeated joint commissioning (at least 4 times), and a huge amount of information in the station (There are more than 10,000 pieces of information in a 500kV smart substation), the manual use of special debugging equipment is slow, the work efficiency is extremely low, and the accuracy of manual joint debugging is not high

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

Due to the low accuracy rate of manual joint debugging, it often causes serious incidents of telemetry and remote signal sending errors, and also causes serious accidents of remote miscontrol or refusal to control the primary equipment of substations

[0007] 3) High security risk

Using the traditional method of artificially using special debugging instruments to carry out incremental testing methods requires isolation of secondary circuits such as current, voltage, tripping, and power supply, and high safety risks during the testing process

[0008] 4) directly cause power grid blackout

The remote control joint commissioning test adopts the method of directly remote controlling the primary and secondary equipment in the substation, resulting in a power outage of the primary and secondary equipment in the substation
