摘要(Abstract)：
晶闸管投切电容式消弧线圈因具有调节快速可靠等优点得到广泛采用,而准确测量配电网的电容电流是对消弧线圈进行控制的前提。注入信号法主要通过测量配电网谐振频率从而达到对电容电流的准确测量,避免了对消弧线圈进行频繁调节,给出了TSC式消弧线圈控制器的系统设计。
The arc suppression coil of thyristor switched capacitor(TSC) featured by rapid adjustment and reliability is widely used.Accurate measurement of the capacitance current in the distribution network is the prerequisite to controlling arc suppression coil.It is achieved in the signal injection method by measuring the resonant frequency in the distribution network with no need of adjusting arc suppression coil frequently,the systematic design of the TSC arc suppression coil controller is provided.
