Low-voltage transformer area zero line fault judgment method based on voltage curve clustering

The invention discloses a low-voltage transformer area zero line fault judgment method based on voltage curve clustering, and the method comprises the steps: carrying out the clustering of a voltage curve of a user meter of a low-voltage transformer area, and judging whether a zero line fault exists in the low-voltage transformer area or not according to a clustering result. The problems of low automation degree, low judgment efficiency and relatively high operation and maintenance cost of zero line fault detection in a traditional mode can be solved, and a basis can be provided for diagnosis and treatment of the zero line fault of the low-voltage transformer area of a power supply company. 本发明公开了一种基于电压曲线聚类的低压台区零线故障判断方法，本发明的基于电压曲线聚类的低压台区零线故障判断方法通过对低压台区用户表的电压曲线进行聚类，根据聚类结果判断低压台区是否存在零线故障，可以解决传统方式下零线故障检测自动化程度低、判断效率低下、运维成本较高的问题，能够为供电公司低压台区零线故障的诊断及治理提供依据。
