摘要: 为了实时监测矿用高压电缆的绝缘状态，提出了一种基于广域测量系统（WAMS）的矿用高压电缆绝缘在线监测方法。该方法利用WAMS实时同步获取电缆线路首末两端的电压和电流，通过建立电缆线路对地等效电路模型推导出电缆的绝缘电阻、等值电容，从而动态监测电缆的绝缘状态。仿真结果表明，该方法测量精度满足矿用高压电缆绝缘在线监测要求，且随着电缆绝缘劣化程度增加，该方法测量误差逐渐减小。Abstract: In order to monitor insulation condition of mine-used high voltage cable in real time, an online monitoring method of mine-used high voltage cable insulation based on wide area measurement system(WAMS) was proposed. In the method, real-time voltage and current of cable ends are obtained synchronously by use of WAMS, and insulation resistance and equivalent capacitance of cable are derived through establishment of equivalent circuit model of cable to ground, so as to realize dynamic monitoring of cable insulation condition. The simulation results show that measurement error of the method decreases with increase of cable insulation deterioration, which meets precision requirement of online monitoring of mine-used high voltage cable insulation.
