基于保护和录波信息的分布式故障分析系统子站部分的设计与实现

istributed fault analysis system is divided into master station which is located in dispatching side and substation which is located in transformer substation, substation transport compressed recorder files and the preliminary analysis result of protective relaying and fault recorder data to the master station which is responsible for overall analysis. On the one hand, the redundancy rate of the data source of the fault analysis system has been improved, so as to the accuracy and the reliability improved; on the other hand, decrease the unnecessary transmission, so as to the pressure of the master station and the communication system reduced. Based on the on-site experience of project in Shuozhou city Shanxi Province and Liaocheng city Shandong, introduce communication system and fault analysis system in detail.
