摘要
偏磁式消弧线圈的现有调谐方法 ,在电网极度平衡地区 ,电容电流检测精度受到限制。本文提出采用注入法的偏磁式消弧线圈的新型调谐方法 ,并进行系统设计 ,研发出基于双机通讯式的采用注入法的偏磁式消弧线圈控制器样机。试验结果表明 ,新型原理正确 。
This paper and analyses the previous control method of petersen coil with magne tic bias,then point out its limitation.A new method for petersen coil with magn etic bias is presented.The capacitive current detector based on injecting variou s frequency signal is worked out and it can communicate with the previous excita tion system to control the magnetic bias petersen coil.The results of experimen ts of prototype show the measuring with injection signal is correct and effectiv e.
