基于XGBoost-CNN的多端有源配电网故障检测
Multi-terminal active distribution network fault detection based on XGBoost-CNN
摘要
Abstract
With the increasing number of distributed power sources and new energy users in the distribution grid,the traditional distribution grid has developed into a multi-source structure.In order to prevent the occurrence of reverse power accidents when other distributed power sources continued to supply power to the maintenance area in the branch fault of the multi-source active distribution grid,an improved extreme gradient boosting(XGBoost)algorithm was proposed,and a multi-source active distribution grid fault detection model based on the improved XGBoost algorithm and convolutional neural networks(CNN)was constructed.The peak values of each frequency band voltage,phase-to-phase voltage difference,and 6th harmonic component in the normal and fault states of the multi-source active distribution grid were extracted as the model's input,and the feature data was processed by the CNN network.The simulation experiment results showed that compared with the other three models,the model in this paper had better detection performance and stronger robustness.The model in this paper could effectively and accurately isolate the fault area in the distribution grid and prevent reverse power accidents from occurring.关键词
