摘要

配电网由配电设备和相应的传感测量网络组成

由于传感器自身可能出现故障

容易导致告警漏报或误报

这给配电系统的故障检测带来了困难

特别是难以区分馈线区段故障和传感器故障。针对配电网传感器故障检测问题

首先

提出了一种基于能量平衡的故障检测方法

给出了能量网络模型的构建和描述方法。然后

基于能量平衡这一基本物理定律建立电气测量数据之间的关联模型。该方法在没有馈线故障信息的情况下

利用传感器之间的相互校核

可以甄别配电网传感器故障。最后

利用仿真实验证明了该方法的有效性。

Abstract

Distribution network consists of distribution devices and corresponding sensor networks. The failures in the sensor itself will miss or mistake the alarm

which brings difficulties to fault detection. Moreover

it is difficult to distinguish the failure between devices and sensors. In order to solve at the detection problem of the sensor fault in distribution network

a sensor fault detection method for distribution network based on energy balance is proposed. The construction method of energy network model is given. According to the basic physical law of energy balance

an association model between electric measurement data is established. This method can be used to detect sensor faults by checking the sensors themselves without feeder fault information. Finally

simulation results show the effectiveness of the proposed method.
