调匝式自动补偿消弧装置调谐测量原理研究

针对调匝式自动补偿消弧装置现有调谐方法测量精度差、不能适应在牵手变电站中并联运行等问题,提出了利用谐振法结合曲线拟合法测量系统电容电流的方法。该方法测量精度高,调档数目少,能自动并联,无需相互通信,适合在各种场合并联运行。模拟电网试验和现场运行试验结果令人满意。

Study on tuning principle of multi-tap automatic compensation arc-suppression device

In view of some problems on forthcoming tuning method, such as low measurement accuracy and not being adaptive to parallel operation in ring distribution system, this paper proposes a new tuning method for multi-tap automatic compensation are-suppression devices, using resonance method coupling curve-fitting. With the new method, high measurement accuracy is acquired and parallel operation of are-suppression coils in ring distribution system is easy to implement. It needs no communication between each other. The experiment and operation results are satisfietory.
