Research on the remote automatic test technology of the full link of the substation relay protection fault information system

Abstract

In view of the fact that the actual operation information of sub-station relay protection device and the point table information of relay protection fault information system are still manually point-by-point proof reading. There are still problems such as low automation, long test time and low point-to-point debugging efficiency of the relay protection fault information system. This article proposes the full-link automatic test technology of the relay protection fault information system, and expounds its principle, main modules and key technologies. The full-link automatic test platform of the relay protection fault information system includes three parts: the main station remote test module, the sub-station test management module and the automatic test module. There are organically combined to realize the remote full-link automatic test, the main station, the sub-station and the spacer layer protection device function multi-step proofreading, automatic result evaluation and automatic report generation function in the entire process. The pilot application of the project shows that the full-link automatic test platform of the relay protection fault information system covers a wide range, can be automatically tested by one key, and has high accuracy. Therefore, it has a wide range of application prospects.
