摘要
针对亭子口水利枢纽电站500kV角形接线方式下的过电压配合、避雷器设置、合闸电阻配置以及铁磁谐振防止等主要问题,利用电磁暂态程序的分析方法进行了计算分析。根据分析结果,提出了相应的设计方案,解决了近年来类似大型水电站500 kV GIS高压配电装置设计中的常见问题,其研究方法和解决方案可供其他类似工程参考和借鉴。
Through the implementation of the electromagnetic transients program,the overvoltage coordination,arrestor arrangement,closing resistor and ferromagnetic resonance were calculated and analyzed under the mode 500kV angular connection of Tingzikou Hydropower Station. The corresponding design scheme is proposed according to the analyzing results to solve those problems existed in the design of 500kV GIS high- voltage distribution device of a large- scale hydropower project in recent years. The research method and corresponding solution can be a good reference for other similar projects.
