Research on Automatic Verification of Relay Protection Setting in Substation Under Data Fusion
A data fusion based automatic verification method for substation relay protection settings has been designed to address the issue of long average verification time caused by the complexity and large amount of data in the substation relay protection system.Translate various complex and variable fixed value orders into a standardized data framework,collect relay protection fixed value data,and then use advanced data fusion technology to comprehensively analyze multi-dimensional information such as fixed value settings,historical fault records,and environmental factors,accurately identify weak areas in relay protection fixed values.A deep sensitivity and selectivity evaluation was conducted on the identified weak areas,and the protection settings were automatically adjusted based on the evaluation results,achieving automatic verification of relay protection settings in substations.The experimental results show that the automatic verification method proposed by the research institute compresses the average verification time to within 0.3 minutes,and its efficiency improvement is particularly significant compared to the methods in reference[1]and reference[2].
