基于多源故障信息的故障定位方法在配网抢修中的应用

Application of Fault Location Method Based on Multi-source Fault Information in Repair of Distribution Network

为提高配电网故障定位速度和精度,提出了基于多源故障信息的配电网故障定位方法。首先提出了适合配电网故障定位的拓扑结构描述和存储方法,然后基于配电网的拓扑结构,对配网故障信息进行一体化处理,利用配电设备的关联关系实现故障信息的分组和优先级的确定,采用模糊集理论实现了在低压故障信息漏报、误报情况下的低压故障定位,最后通过算例验证了该方法的有效性。

Fauh location method based on multi-source fault information in repair of distribution network is proposed to achieve high speed and precision in fault location. Firstly a topology description and storage method which is ap- propriate to distribution network fault location is proposed. Then, based on the topological structure of distribution network, fault information on the distribution network is processed integrally. Fault information grouped and priorities are identified using the association of distribution equipment. Low-voltage fault location is achieved by applying fuzzy set theory in fault message omissions and misstatements situations. Finally, an example demonstrates the effectiveness of this method.
