摘要
琅琊山抽水蓄能电站的发电机系奥地利进口产品,不能使用国内常用的消弧线圈接地的定子接地保护,而是采用单相接地变压器保护。文章介绍了如何在电站配用20Hz电源进行100%定子绕组的单相接地保护和基波零序过电压保护。
The generator of the Langyashan Pumped Storage Power Plant was imported from Austria, which could not apply the common-used arc-distinguished coil ＆ earthing-protection but the single-phase transformer at the neutral point of the stator to protect the stator. Also, the 20Hz power supply was employed to carry out the zero- sequence excess voltage protection and 100% stator winding single-phase earthin^-orotection.
