智能变电站继电保护状态监测算法设计

Intelligent Substation Relay Protection Condition Monitoring Algorithm Design

针对继保设备运行状态表征的模糊特性,引入模糊数学中的模糊综合评判模型来作为继保设备运行状态量化的手段,以实现对其作出准确评估,进而制定合理的检修策略。实例证明,该类算法简单、有效,能在大幅削减检修费用的同时提升变电站系统的可靠性,值得智能变电站推广使用。

In view of the fuzzy characteristics of the equipment running state, the introduction of fuzzy mathematics, in the fuzzy comprehensive evaluation model for the equipment running status of quantitative method, in order to realize the accurate evaluation, formulate the reasonable maintenance strategy. Examples show that the algorithm is simple and effective, can sharply cut maintenance cost while increasing the reliability of the substation system, is worth popularizing intelligent substation.
