Real-Time Fault Diagnosing Models and Method for Communication Network in Smart Substation
摘要
Abstract
In order to improve operation and maintenance of communication networks in smart substations, a communication network fault diagnosing method based on information from network analyzer is presented. Implementation sketch of fault diagnosing is presented and communication network model, consisting of a network connection model, a source model and a sink model, is established. Based on communication network model, a packet transmission path searching algorithm is proposed to establish mapping between communication relationship and device entities. Then, this paper presents a network fault diagnosing algorithm. Finally, process bus network of 110 kV side in a typical 110 kV substation is taken as example to analyze the proposed method. Analysis results show that the fault diagnosing method has sufficient accuracy and project effectiveness, which can help to guide operation and maintenance crew to quickly restore normal operation of communication network.关键词
