摘要
简述了引起35kV系统铁磁谐振过电压的原因及其危害,总结多年来防止35kV系统铁磁谐振过电压的各种措施,提出采取35kV零序TV防止35kV系统铁磁谐振过电压的最佳措施。同时对35kV母线压变加装零序TV前后和可能出现的各种异常运行状况作了对比分析,并且提出了加装35kV零序TV的具体实施方案。
Through the analysis on the cause and the damage of arousing 35 kV system ferromagnetic resonance over-voltage, has Sumed up various measure about guarding against 35 kV system ferromagnetic resonance over-voltage from many years, has suggested that the zero sequence TV is the best measure to guard against the 35 kV system ferromagnetic resonance over-voltage . The text also analyses the difference when the 35 kV bus voltage transformer adds the zero sequence TV and no, and comparative analyses the possible various abnormal operational states, also, puts forward a detailed implementary method on how to add 35 kV zero sequence TV.
