| 摘 要： | 针对电力系统中有大量的储能元件组成许多串联或并联的振荡回路,在正常的稳定状态下运行时,不可能产生严重的的振荡,而当系统发生故障或由于某种原因电网参数发生了变化时,就很可能发生谐振的问题,以溪洛渡电站投产初期发生的两起铁磁谐振过电压情况为背景,研究了在500 k V GIS开关站中铁磁谐振过电压发生的原因,提出了相关处理改进措施。

| Abstract: | A large number of energy storage components are used in the electric power system , which form a lot of series or parallel oscillation circuits .Under a stable operation state , serious oscillation will not occur .But when the system fails or grid parameters change , resonance phenomenon may occur .Two ferromagnetic resonance overvoltage accidents happened in the 500 kV GIS switching station of Xiluodu Hydropower Station are studied .Possible reasons of the faults are analyzed and corresponding treatment measures are proposed . |
