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,本文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,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,仿真实验表明了该方法的有效性。
Abstract:
      Distribution network consists of distribution device and sensing network. The sensor failure will cause false positives or false negatives. This phenomenon brings difficulties to the fault detection, especially it is difficult to distinguish between device failure and sensor fault. A sensor fault detection method for distribution system based on energy balance is proposed. The construction method of energy network model is given. Based on 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 without feeder fault information. Simulation results show the effectiveness of the proposed method.
