摘要
分析了负序电流产生的原因,以及负序电流对发电机组和电力系统产生的危害;给出了基于两相CT小接地电流系统下负序电流的获得方法,并给出了相应的硬件电路实现。
This paper introduces a method to measure the negative sequence current. The reason to the negative sequence current and the damage to the generator and power system are analyzed. A practicable arithmetic for the negative sequence current in the ground small-current system of two-phase CT connection is given, and the hardware circuit is presented.
