Fuzzy Comprehensive Evaluation Method for On-line Monitoring Data Quality of Substation Equipment

摘要

This paper analyses the existing problems in on-line monitoring and data quality evaluation of substation equipment, and proposes a multi-dimensional fuzzy comprehensive evaluation method for on-line monitoring data quality of substation equipment. The evaluation index set of online monitoring data quality of substation equipment with 5 dimensions and 11 secondary indexes is established. The weight is determined by combining subjective and objective methods. The fuzzy transformation is completed based on membership function and a multi-dimensional fuzzy comprehensive evaluation model is established. Finally, the evaluation grade of online monitoring data of substation equipment is obtained. Finally, compared with other methods, the validity and accuracy of this method are verified.
