摘要：

Aiming at the difficulty of fault location caused by frequent multi-channel simultaneous warning events of optical communication subsystem carrying relay protection service in power system, a fault locating method for relay protection communication system is proposed based on big data of power grid operation and maintenance and the Bayesian network model processing method. Combining with the warning information of RPMS(Relay Protection Management System) and communication network management system, combined with information of OMS(Operation Management System), the fault locating area is reduced. Then based on the prior probability calculated by historical operating data, the fault probability is calculated by the improved Bayesian algorithm to infer the cause of fault, and the fault is located by means of the information of communication resource management system. The results of case study prove the validity and accuracy of the proposed method. The proposed method is also suitable for multi-zone fault locating simultaneously. © 2019, Electric Power Automation Equipment Press. All right reserved.
