基于粗糙集理论的真空断路器故障诊断方法

Fault Diagnosis Method Based on Rough Set Theory for Vacuum Circuit Breaker

真空断路器的故障和征兆总是存在着随机性、模糊性和不确定性。以粗糙集理论为基础的,用于真空断路器故障诊断。通过以故障征兆为条件属性集,以故障为决策属性集,建立故障诊断的决策表,通过约简决策表,剔除冗余条件属性,建立起征兆与故障的决策规则,从而快速、准确地诊断真空断路器的故障。

The symptoms and faults are always random, fuzzy and uncertain in vacuum circuit breakers. The method based on rough set theory is used in fault diagnosis of the vacuum circuit breakers. By taking fault symptoms as condition attribute set and fault as decision attribute set, the decision table for fault diagnosis is established. By reducing decision table to cut off redundant condition attribute, the rules between symptoms and faults are established. It makes the fault diagnosis of the vacuum circuit breakers fast and accurate.
