摘要
用EMTP仿真计算了10kV中性点不接地系统电磁式TV饱和引起的铁磁谐振。应用4TV法前后计算结果对比说明4TV接法可有效抑制但不能杜绝铁磁谐振且其谐振电压有高频分量较低频分量的频率更低等一些新特点。
The ferroresonance, which results from the electromagnetic potential transformer in a 10 kV distribution system, is simulated and studied by the Electro-Magnetic Transient Program （EMTP）. Through the simulations with and without the method of setting the fourth TV between the 3-phase TV＇s neutral point and the ground, it is concluded that the 4TV method can restrict the ferroresonance effectively. But the feroresonance can not be eliminated totally by this method and there are some new traits of ferroresonance in the system with the method.
