Power grid fault detection method and device

Abstract

The invention discloses a power grid fault detection method and system, which relate to a cloud server, an edge server and a plurality of sensor nodes in communication connection in sequence. The method comprises the steps of obtaining historical power data through the cloud server, constructing a target power load type identification model by adopting historical power data and a preset multi-layer perceptron, sending the target power load type identification model to an edge server, acquiring real-time power data from the corresponding power utilization ends through a plurality of sensor nodes and sending the real-time power data to the edge server, inputting the real-time power data into a target power load type identification model through an edge server to obtain a first power load type corresponding to the real-time power data, and respectively returning the first power load type to the corresponding sensor nodes. According to the method, whether the power utilization end has thefault is judged through the sensor node based on the comparison result of the first power load type and the real power load type corresponding to the real-time power data, the communication delay canbe reduced, and the fault of the power utilization end can be detected in time.
