Testing system and method for whole station information intelligent point alignment of digital substation

Abstract

The invention discloses a digital substation whole station information intelligent point-to-point testing system and method. The system includes a point-to-point server, an intelligent point-to-point tester and intelligent substation equipment including a device to be tested. The point-to-point server parses the SCD file and 104 point table files, establish the corresponding relationship between substation information data and telecontrol point table data according to semantic information matching, generate a test plan and send it to the intelligent point-to-point tester; the intelligent point-to-point tester receives the test plan from the point-to-point server, drives The peer server realizes the reading and remote control operation of the remote signal / telemetry signal of the smart substation equipment through the 104 protocol, and directly reads the device data from the smart substation equipment through the MMS specification, performs test judgment, and sends the test result data to the peer Point server; the point server receives test data from the intelligent point tester and generates a test report. The invention can greatly improve the point-to-point work efficiency, reduce labor costs, and shorten the debugging period.

Description

technical field [0001] The invention relates to a power system automatic debugging device and method, in particular to a digital substation whole station information intelligent point-to-point testing system and method. Background technique [0002] Usually, the point-to-point test in the substation consists of four parts: remote signal point-to-point, telemetry point-to-point, remote remote control point-to-point, and protection information (action information, alarm information) point-to-point. For conventional substations that use analog voltage and current input and hard contact input and output, the analog or input signal can only be manually applied to the corresponding device, and the signal change can be checked through the background of the remote control device to see if it is correct. [0003] With the popularization and application of digital substations, intelligent electronic devices (Intelligent Electronic Devices, IEDs) in the substation are modeled using the...

AI Technical Summary

Problems solved by technology

[0004] At present, the point-to-point work of the whole station information of the digital substation is still manually tested one by one. Usually, there are thousands of signals that need to be tested in each substation, which brings a huge workload to the on-site commissioning personnel. A large number of manual point-to-point processes are also prone to errors, which brings safety hazards to the normal operation of substations
