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(guān)閉規(guī)律 ;針對可逆機組獨特的過流特性 ,設(shè)計了具有延時段的三段折線關(guān)閉規(guī)律 ,在減少總關(guān)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(guān)閉與機組轉(zhuǎn)速上升聯(lián)合作用引起的水錘壓力 ;介紹了考慮轉(zhuǎn)速信號反饋的可逆機組導葉關(guān)機規(guī)律 ;為抽水蓄能可逆機組的事故緊急關(guān)機規(guī)律的設(shè)計提供了一種新思路。
