中文摘要:

配电网是电网中发生短路故障最多且智能化程度较低的地方。目前主要使用基于零序电流比幅法来进行接地故障的故障诊断，但存在非接地故障识别率低和无法快速识别等问题。采用5G通信技术，提出三序复合电流检测法并结合广义回归神经网络（GRNN，generalized regression neural network）来实现配电网故障诊断的实时传输与快速决策。测试结果表明可提升非接地故障的识别率达20%以上，解决了以往通信不可靠和故障诊断智能化不高等问题。

英文摘要:

Distribution network is the place with the most short circuit faults and low degree of intelligence. At present, the zero-sequence current amplitude comparison method is mainly used for fault diagnosis of grounding fault, but there are some problems such as low recognition rate of non-grounding fault and unable to identify quickly. 5G communication technology is adopted, three-sequence composite current detection method is proposed, and generalized regression neural network (GRNN) is combined to realize real-time transmission and rapid decision-making of fault diagnosis in distribution network. The test results show that the recognition rate of non-grounding fault can be improved by more than 20%, which solves the problems of unreliable communication and low intelligent fault diagnosis.
