摘要
通过仿真分析了影响铁磁谐振产生的两个重要因素,并给出了铁磁谐振发生时各相电压的特征。在模拟10kV电网实验室进行物理实验,证明了仿真结论的正确性。
The electromagnetic PT excited ferroresonance in neutral point ungrounded system is studied. The mathematical model of PT is established based on the circuit principles. The equivalent circuit of system is simulated with a 10kV net model, The behaviors of each phase with ferroresonance are analyzed. Two factors influencing ferroresonance are obtained. Simulation result indicates that the occurrence of ferroresonanee and neutral voltage amplitude are influenced by the line length and faulted voltage recovery phase.
