Intelligent online monitoring of power capacitor complete equipment in substation

The general structure of capacitor complete equipment inside the substation and internal structure of single capacitor are introduced and analyzed in this paper. Based on this, a mathematical model is established to simulate several possible damages of internal component of single capacitor by using computing software, and then some applicable conclusions are drawn. In accordance with China´s overall trend of developing smart grid, a system of intelligent online monitoring applicable to the substation capacitor complete equipment is figured out, and a pre-detection of fault symptom of the power capacitor is able to detected, and the fault could be analyzed and located.
