摘要
文章针对智能电网环境下配电网故障定位的复杂性,提出了多源信息融合的故障定位方法,解决了分布式电源(DG)接入引发的故障特征复杂化、多源数据异构性及抗干扰能力不足等问题,完善了智能电网故障诊断的技术体系。结果表明,新型故障定位法精度更高、适应性更强,为高比例新能源接入的智能电网提供了高精度、强鲁棒性的故障定位解决方案。
In view of the complexity of distribution network fault location in the smart grid environment,this paper proposes a fault location method based on multi-source information fusion,which solves the problems of complex fault characteristics,multi-source data heterogeneity and insufficient anti-interference ability caused by distributed generation(DG)access,and improves the technical system of smart grid fault diagnosis.The results show that the new fault location method has higher accuracy and stronger adaptability,and provides a high-precision and robust fault location solution for smart grids with a high proportion of renewable energy access.
