超高海拔抽水蓄能电站发电电动机及其配套开关设备适应性提升技术研究
Improvement on the Adaptability of Generator-Motor and Switchgear of Pumped-storage Power Stations in Ultra-high Altitude Region
摘要
Abstract
In view of the difficulty in selecting generator-motor and switchgear for the pumped-storage power stations in ultra-high altitude region,the design and manufacturing difficulties of generator-motor and switchgear are introduced.By studying the main influencing factors such as the insulation and anti-corona,ventilation and cooling,and electromagnetic design of generator-motor,and the insulation level of switchgear,the adaptability improvement path of these equipments under ultra-high altitude condition is analyzed.Finally,a preliminary selection scheme for key parameters such as rated voltage and unit capacity of generator-motor for the pumped-storage power stations in ultra-high altitude region is proposed,in order to provide reference for the planning and design of pumped-storage power stations in ultra-high altitude region in the future.关键词
