Research on Voltage Fault Location of Secondary Circuit Node in Intelligent Substation Based on Neural Network
To solve the problem of voltage fault location in secondary circuit nodes of relay protection,this article designs an intelligent substation secondary circuit node voltage fault location method based on neural network.Firstly,establish a database of secondary circuit node voltages and analyze fault data to identify the characteristics of voltage anomalies.Next,generate a fault status matrix and compare it with real-time monitoring data.Finally,a fault localization model is constructed to accurately locate voltage faults in the secondary circuit nodes of intelligent substations.The experimental results show that the method has a localization accuracy of 88.9%for 9 fault samples,with high accuracy and strong ability in handling multi-point faults.
