A Statistical Analysis System for Protective Relays Based on Protection Verification Data
In order to solve the statistical efficiency problem of relay equipment in power systems,a protective relay sta-tistical analysis system based on protection verification data is designed.In terms of hardware,information storage chips,relay drive circuits,and relay oscilloscopes are designed.In terms of software,based on protection verification data,sam-pling of relay protection information data is implemented.Then on the basis of data cleaning,a statistical analysis process for protective relays is designed and implemented.Test results show that the system has excellent performance,less time overhead,and can meet the statistical analysis requirements.
