pumped-storage units

The broken-line closing law of reversible pump-turbine usually used in pumped storage plants is analyzed and discussed.

評述了目前抽水蓄能可逆機組常用的分段折線關閉規律 ;針對可逆機組獨特的過流特性 ,設計了具有延時段的三段折線關閉規律 ,在減少總關閉時間的同時 ,有效的降低了抽水蓄能可逆機組由于導葉關閉與機組轉速上升聯合作用引起的水錘壓力 ;介紹了考慮轉速信號反饋的可逆機組導葉關機規律 ;為抽水蓄能可逆機組的事故緊急關機規律的設計提供了一種新思路。
