基于拓扑图元信息融合的电网故障诊断模型
Power Grid Fault Diagnosis Model Based on Information Fusion of Topological Graph Element
摘要
Abstract
Fast and accurate identification of faulty element is the primary prerequisite for reducing power outages and recovering power quickly.Since most of the existing fault diagnosis methods are modeled for a single element,it is difficult to adapt to the topology change.In this paper,an adaptive fault diagnosis model based on topological graph element information fusion was proposed.The topology incident matrixes of elements,protections and circuit breakers were established according to topological analysis,and taken these incident matrixes as basic graph elements,the information fusion diagnosis model was constructed.Besides,the topology mapping rules for the secondary backup protection and the complete information fusion algorithm were given based on the protection logic and tripping relationship.Finally the case studies of the IEEE 14-bus system show that the proposed method can identify the fault element quickly and accurately,also it has strong fault tolerance and can adapt to the network topology changes.关键词
