摘　　要：对变电站内电容器设备的一般结构和单个电容器内部结构进行了介绍和分析,并在此基础上建立数学模型,用运算软件对单个电容器内部电容元件的几种可能损坏情况进行了仿真,得出了应用性的结论。针对我国发展智能电网的总体趋势,研制一套适用于变电站电容器设备的智能在线监测装置,实现对电力电容器的故障征兆的提前发现,并且对故障进行分析和定位。The general arrangement of capacitor bank in the substation and the internal structure of individual capacitor are introduced and analyzed. Based on this, a mathematical model is established to simulate several possible damages of internal component of individual capacitor by using computa-tion software, and then some applicable conclusions are drawn. According to the overall trend of de-veloping smart grid in China, a system of intelligent on-line monitoring which is applicable to capac-itor installation in the substation is figured out, and a pre-detection of fault symptom of the power ca-pacitor is able to be detected, and the fault could be analyzed and located.
