Intelligent station relay protection calibrator with line reclosing automatic judgment function

Abstract

The invention relates to an intelligent station relay protection calibrator with the function of automatically judging line reclosing. The intelligent station relay protection calibrator includes a programmable hardware platform, a reading and loading interface connected to the programmable hardware platform, and a graphical and human-computer interaction platform connected to the programmable hardware platform. The reading and loading interface is used to receive the SCD file and configuration parameters of the smart substation; the programmable hardware platform is used to parse the SCD file, build the line IDE linked list and virtual terminal list of the smart substation based on the result of parsing the SCD file, and obtain SV and GOOSE data , Based on the SV and GOOSE data, the logical judgment of the line reclosing condition is carried out to obtain the line reclosing judgment result; the graphical and human-computer interaction platform is used to graphically display the line reclosing judgment result. The invention can automatically and quickly judge and display the line reclosing of the intelligent substation, thereby improving the debugging work efficiency.

Description

technical field [0001] The invention relates to the field of relay protection equipment calibration of an intelligent substation in a power system, in particular to an intelligent substation relay protection calibrator with the function of automatically judging line reclosing. Background technique [0002] At present, during the reconstruction and expansion of smart substation lines, commissioning and acceptance, and regular verification, the state of the reclosing switch cannot be automatically judged during the debugging process. Quickly locating the causes of unsatisfied reclosing conditions and parameter configuration errors requires testers to check the reclosing conditions and parameter items one by one, which brings great inconvenience to the debugging of line protection devices and reduces work efficiency. Contents of the invention [0003] The purpose of the present invention is to provide an intelligent substation relay protection calibrator capable of automatica...
