近年來，中國華電集團公司福建安砂水電廠采用“小流量泄洪”，優化梯級水庫調度，與該廠下游的豐海、貢川等電站形成了“梯級聯動、電量增盈”的良好局面。
沙(sha)溪流(liu)(liu)域水道(dao)全(quan)長328公里(li)，流(liu)(liu)域內分布著11座(zuo)大(da)(da)中型水電(dian)(dian)(dian)(dian)站(zhan)。華電(dian)(dian)(dian)(dian)安(an)砂水電(dian)(dian)(dian)(dian)廠從大(da)(da)局(ju)出發(fa)，走互利(li)共贏之路，開展(zhan)“小(xiao)流(liu)(liu)量泄(xie)洪(hong)(hong)”優化調度，提高流(liu)(liu)域的(de)(de)整體經濟效益。“小(xiao)流(liu)(liu)量泄(xie)洪(hong)(hong)”就(jiu)是抓(zhua)住汛期(qi)來水豐(feng)盈的(de)(de)有利(li)時(shi)機，根據沙(sha)溪流(liu)(liu)域水情變化及水庫(ku)(ku)運行(xing)情況，參考(kao)后期(qi)天氣預報情況，合理調控安(an)砂水庫(ku)(ku)的(de)(de)下(xia)泄(xie)流(liu)(liu)量，使梯(ti)(ti)級各(ge)電(dian)(dian)(dian)(dian)站(zhan)盡量實(shi)現滿發(fa)、多發(fa)。“小(xiao)流(liu)(liu)量泄(xie)洪(hong)(hong)”既保(bao)證(zheng)了大(da)(da)壩安(an)全(quan)，騰出防洪(hong)(hong)庫(ku)(ku)容，又促進(jin)了下(xia)流(liu)(liu)各(ge)梯(ti)(ti)級電(dian)(dian)(dian)(dian)站(zhan)增(zeng)發(fa)電(dian)(dian)(dian)(dian)量，充(chong)分利(li)用每(mei)一立方水。2008年，該(gai)廠采用“小(xiao)流(liu)(liu)量泄(xie)洪(hong)(hong)”調度，使下(xia)游梯(ti)(ti)級電(dian)(dian)(dian)(dian)站(zhan)累(lei)計增(zeng)發(fa)電(dian)(dian)(dian)(dian)量600多萬千瓦(wa)時(shi)，最大(da)(da)限度地實(shi)現了沙(sha)溪流(liu)(liu)域效益最大(da)(da)化。
