摘要
变速抽水蓄能机组因可实现机电系统的柔性连接,满足电网有功调峰、无功补偿要求,并具有快速响应、运行稳定性高的优点,受到行业普遍关注。本文介绍了海水抽水蓄能10MW变速发电电动的总体结构、通风结构、绝缘结构,并重点介绍了转子结构,为今后大容量变速发电电动机的设计积累了经验。
Nowadays,much attention has been paid to variable speed pumped-storage units in the hydropower as their flexible connection with electromechanical systems,capability of active and reactive power control as desired,fast response and high stability.In this paper,the general structure,ventilation structure and insulation structure of the 10 MW variable speed generator-motor(VSGM)for seawater pumped-storage are introduced,and the rotor structure is presented in detail,which will lay a foundation for the design of the large capacity VSGM in the future.
