基于可信性理论的高压断路器运行状态评估

Condition Assessment of High Voltage Circuit Breakers Based on Credibility Theory

采用基于可信性理论来评估高压断路器运行状态。根据高压断路器的相关试验和实际运行参数建立了运行状态评估指标体系;然后利用可信性理论和改进的层次分析法构建了一个多层次模糊综合评估模型。最后利用该模型对实例进行了分析评估,验证了模型的可行性与可靠性。

This paper adopts credibility theory to evaluate the operation state of high voltage circuit breakers. Firstly, establish state evaluation index system according to the relevant high voltage circuit breaker testing and actual operat-ing parameters; then use the credibility theory and improved Analytical Hierarchy Process （AHP） to build a multi- level fuzzy comprehensive evaluation model; finally, utilize the model for real case analysis and evaluation and verify the feasibility and reliability of the proposed model.
