利用电力电子扰动技术的系统对地电容检测方法
Detection Method for System Grounding Capacitance Using Power Electronic Disturbance Technology
摘要
Abstract
Accurate calculation of system ground capacitive current is very important for precise compensation for self-tuning petersen-coil.In this paper,the power electronic switch is used to generate disturbed voltage and current containing plenty of frequency components by momentarily controlling its conduction state.The disturbance voltage and current signals are used to measure the ground capacitance in conj unction with the measuring method of harmonic impedance based on power electronic perturbation technique.The method is highly effective,and the impact on the working state of the arc suppression coil can be neglected.Simulation analysis and simulated experiment have proved the effectiveness of the method.关键词
