水擊壓力、機組轉(zhuǎn)速變化等數(shù)據(jù)的計算,稱為調(diào)節(jié)保證計算.調(diào)保計算的目的是:計算引水系統(tǒng)的最大和最小內(nèi)水壓力;丟棄負荷、增加負荷時的機組轉(zhuǎn)速變化率,驗證其是否在允許范圍內(nèi);選擇水輪機調(diào)節(jié)器調(diào)節(jié)時間和調(diào)節(jié)規(guī)律,保證壓力和轉(zhuǎn)速變化在允許值范圍內(nèi);研究減小水擊壓力及機組轉(zhuǎn)速變化率的措施.本文以緬甸境內(nèi)太平江一級水電站4臺機組為原型,重點對電站機組調(diào)節(jié)保證計算進行分析.
