摘　　要：采用新的测试原理并与微机技术相结合 ,实现了补偿电网脱谐度的直接测量。并在此基础上直接以脱谐度为控制信号 ,设计了消弧线圈的自动跟踪调谐系统 ,其特点是 :跟踪速度快 ,响应时间不足 2 0s;测量误差小 ,脱谐度的测量误差不大于 0 6 4 % ,电网电容电流的测量误差不大于 2 % ;此外系统还具有可靠的状态识别功能和良好的抗干扰能力 。A new method principle is adapted and microprocessor technology is combined, which makes direct measurement of turn off degree of compensation network achieve. At the same time, a system of automatically tracing resonant regulation of petersen coil is designed that takes turn off degree as the controlled signal. Its response time is shorter than 20?s with error of turn off degree in measurement less than 0.64% and error of capacitive current in measurement less than 2%. In addition, it is imbued with reliable function of distinguishing state and interference resistant to guarantee the regular operation.
