摘要

针对电网继电保护方式安排可靠性与智能性仍需提高的现状,提出了基于Petri网理论的智能签票系统防误算法.通过对电网基础数据进行网络拓扑分析,采用分层分类的方法描述操作规则.根据签票语料拓扑结构和防误专家知识库建立Petri网理论模型,实现智能化的签票系统防误功能.实际运行表明,基于Petri网理论的继电保护智能签票系统的防误算法能够对保护方式安排提供准确丰富的校验结果,保障电网保护方式安排操作的准确性与安全性.%Aiming at the status that the reliability and intelligence of power protection alteration scheme design needs to be improved, an intelligent anti-misoperation algorithm based on Petri net theory is put forward to verify a power protection alteration scheme automatically. The first step is to implement topological analysis for grid basic data, then the operating regulation is described based on methods of stratification and classification. The anti-misoperation method of power protection alteration schemes is built by the Petri net theory model which is based on the corpus topology and experts knowledge base. The practical operating shows that the anti-misoperation algorithm for power protection alteration scheme based on Petri net theory has the ability to provide accurate and abundant verification results, which therefore ensure the accuracy and security of the power protection alteration scheme.
