Evaluation method for power distribution system based on set pair analysis

According to the characteristics of power distribution system and the commonly used communication mode, the evaluation index system of the communication system for power distribution system, which includes 4 kinds of indexes, including economy, reliability, technology and security is established. Based on the set pair analysis, a comprehensive evaluation model of the communication system for power distribution system is established. By calculating each evaluation index, establishing ideal scheme and negative ideal scheme of the communication system, constructing identity-discrepancy-contrary connection degree of alternative scheme and the ideal scheme, and analyzing the identity-discrepancy-contrary connection degree, a set pair evaluation method of communication system for power distribution system is proposed. The method, with simple structure and a small amount of computation is easy to operate. The results of calculating example show that the set pair evaluation method of the communication system for the power distribution system is reliable and it is an effective method.
