基于模糊逻辑的断路器状态检测

Using Fuzzy Logic for Diagnosis of Technical Condition of Power Circuit Breakers

高压断路器的监测与诊断是提高电力系统可靠性和安全性的一项重要工作,本文基于模糊逻辑推理建立了一套高压断路器模糊的故障诊断方法。通过该方法对高压断路器运行数据进行模糊化处理,有效降低了谐波信号对故障诊断过程的影响,同时通过断路器运行的典型故障特征分析,进而实现对断路器的状态检测。

Monitoring and diagnosis of high voltage circuit breaker is an important character to improve the reliability and safety of the power system.This paper establishes a set of fuzzy fault diagnosis method of high voltage circuit breaker based on fuzzy logic reasoning.This method blurs the high voltage circuit breaker operation data and effectively reduces the influence of harmonic signal process of fault diagnosis.Using the fuzzy fault diagnosis method through the analysis of the typical fault characteristics of the circuit breaker operation at the same time, detecting the state of the circuit breaker.
