A Comprehensive Performance Evaluation Method of the Distributed Common Grounding Electrode

Aiming to enhance the comprehensive performance of the distributed common grounding DC electrode, reduce the construction cost, and solve the problem of optimizing the topology of distributed common DC grounding electrode, a comprehensive performance evaluation method is proposed. In this paper, three evaluation indexes of the distributed common grounding electrode topology is established. Based on the parameters in Guangdong Province, the weight of each index is calculated by the Criteria Importance Through Intercriteria Correlation and the Analytic Hierarchy Process, and the comprehensive performance of the typical topologies are evaluated by the Technique for Order Preference by Similarity to an Ideal Solution. The proposed evaluation method can effectively evaluate the comprehensive performance of the distributed common grounding electrode under different topologies, and the star topology shows better comprehensive performance. This study provides a reference for the selection of distributed common grounding electrode topology.
