摘要
在消弧线圈接地补偿基础上,提出了一种基于IGBT新型消弧接地补偿装置.该装置采用跟踪型PWM技术对接地故障电流进行补偿,补偿速度快、范围宽,并克服了由于传统消弧线圈的引入对系统产生的不良影响,可以随时补偿,随时退出运行.用专业的PSCAD/EMTDCTM和MATLABTM对模型进行仿真.仿真结果表明,该方法可以有效地对接地电流补偿.
A new Ground Faulty Neutralizer using power switch （IGBT） is proposect tn tins paper, which can compensate the cun＇ent of ground faulty quickly because of using the PWM method. The new Ground Faulty Neutralizer can overcome the disadvantages Peterson Coil may bring to power system. The related simulation was performed using the software of PSCAD/EMTDC^TM and MATLAB^TM, the result can show that this method can compensate the cun＇ent of ground faulty effectively.
