摘要
电磁式电压互感器(PT)造成的铁磁谐振过电压是中性点不接地的电力系统中最常见和造成事故最多的一种内部过电压,一直以来还没有完善的解决方法,影响电力系统的安全运行.用非线性电路相平面的观点定性分析了初始相位对铁磁谐振的影响,并给出示例,说明铁磁谐振研究中数值仿真和实验的可比性关系.
The ferromagnetic resonance caused by the electromagnetic potential transformer(PT) is one of the most common overvoltage in ungrounded systems. Without a perfect solution, it always endangers the safety of the systems. Qualitativly analyzing the ferromagnetic resonace system with nonlinear theory shows initial phase play an important role in behaviors of the system. Some examples given explain how to compare numerical simulation and experiment in ferromagnetic resonance studying.
