19、備用容量（1）水電站負(fù)荷備用容量水利動(dòng)能設(shè)計(jì)規(guī)范中規(guī)定，調(diào)整周波所需要的符合備用容量，可以采用系統(tǒng)的負(fù)荷的5%左右,大型電力系統(tǒng)可采用較小值，因此這里取5%計(jì)算，得：n負(fù)荷=98父5% =4.9萬kw。又因?yàn)樵谙到y(tǒng)中，由于火電機(jī)組技術(shù)特性的限制，火電站擔(dān)任系統(tǒng)的調(diào)頻任務(wù)比較困難，且單位電10且可以且不得5%時(shí),能的耗煤率增加，不經(jīng)濟(jì)。而水電站在擔(dān)任調(diào)頻方面比火電站方便，對系統(tǒng)應(yīng)付負(fù)荷變化有利， 降低火電站的單位電能的耗煤率。因此，此系統(tǒng)中的的負(fù)荷備用容量全由水電站承擔(dān)，即：n負(fù)備=98父5% = 4.9萬kw(2)水電站事故備用容量水利動(dòng)能設(shè)計(jì)規(guī)范中規(guī)定，電力系統(tǒng)的事故備用容量可采用系統(tǒng)最大負(fù)

20、荷的10%左右,小于系統(tǒng)中最大一臺(tái)機(jī)組的容量。據(jù)此取水電站事故備用容量為系統(tǒng)最大負(fù)荷的10%計(jì)算得出:n 事故=98x10% =9.8 萬kw由于電力系統(tǒng)中的事故備用容量要分布在電站上，事故備用容量的使用時(shí)間較長，水電站承擔(dān)事故 容量時(shí)，要預(yù)留一定的事故備用庫容，會(huì)增大水電站的投資，當(dāng)算出的v事備大于水庫調(diào)節(jié)庫容的 才不承擔(dān)全部事故備用容量。按水利動(dòng)能設(shè)計(jì)規(guī)范計(jì)算，、,tn 事備360 m9.88 38 3v事備 =0.26 父 10 m 5%v興 =0.21父10 m0.00272” h min0.00272 父 8.5 父 57.55所以水電站不適宜承擔(dān)全部事故備用容量。系統(tǒng)備用容量在水、

21、火電站之間的分配，應(yīng)根據(jù)各電站容量的比重、電站機(jī)組可利用的情況、系統(tǒng) 負(fù)荷在各地區(qū)的分布等因素確定。本設(shè)計(jì)主要依據(jù)各電站容量的比重來分配系統(tǒng)備用容量。.，n水由13 11故有：n水備= m n事備=m9.8 = 2.85kw；n7k 電 +n 水電13.11+31.5水電站的備用谷n為 n水備=n事備十n水備=7.7萬kw ；水電站的必需容量為 n必=n水工+n水備=13.11+7.7 = 20.81萬kw 。(3)水電站的重復(fù)容量的確定水電站重復(fù)容量的設(shè)置，要額外增加水電站的投資和年運(yùn)行費(fèi)，因此，重復(fù)容量需要經(jīng)過動(dòng)能經(jīng)濟(jì) 分析確定。水輪機(jī)在正常蓄水位的過水能力可通過公式：qmax = n必

22、試算得到;a h式中：n必一一為水電站的必需容量；a 為系數(shù)；h 為正常蓄水位時(shí)上下游水位差；經(jīng)試算可以得到：qmax =341.5m3/s。12分別對枯水年、平水年、豐水年流量資料進(jìn)行歷時(shí)調(diào)節(jié)計(jì)算如下表:水庫年調(diào)節(jié)歷時(shí)列表計(jì)算（未計(jì)入水量損失，按豐水年計(jì)算）時(shí)段（月）天然來水各部門綜合用水多余或小足水量棄水時(shí)段末興利庫容蓄水 量（106m3）出庫總流量（m3/s）油(m3/s)水量 (106m3)(m3/s)水量 (106m3)多余 (106m3)不足 (106m3)水量 (106m3)油(m3/s)豐水 期3111.00291.5559.73156.88134.660.000.00364.
