Aiming at the power grid failure caused by various factors during the operation of transmission and transformation equipment,a new fault diagnosis method is proposed.Based on the big data technology and the Internet of Things technology,this method builds an IoT detection system including data acquisition layer,data transmission layer,data analysis layer and data monitoring layer,and realizes the IoT information communication of the underlying equipment.In the process of fault diagnosis,the traveling wave positioning method and BP neural network algorithm model are also integrated.Through the wave positioning method,users can obtain the real-time transient voltage and transient current data of different monitoring nodes in power transmission and transformation equipment,and then quickly,accurately locate the fault occurrence location of transmission and transformation equipment.The BP neural network algorithm model is used to further optimize the fault information after traveling wave localization,and more accurately learn and train the fault location information of the located transmission and transformation equipment to improve the fault data processing capability of the transmission and transformation equipment.Experiment shows that the error rate of the proposed scheme is low,which greatly improves the fault diagnosis capability of transmission and transformation equipment,thereby improving the overall system operation efficiency.
