8月6日，在國網福建省電力有限(xian)公(gong)司調(diao)控中(zhong)心，水(shui)情(qing)調(diao)度(du)(du)人員根據氣象部門預報的第13號臺風“蘇迪羅”降(jiang)雨信(xin)息，利(li)(li)用福建電網大型水(shui)庫(ku)短期徑流(liu)預報調(diao)度(du)(du)系(xi)統顯示的水(shui)庫(ku)短期徑流(liu)預報信(xin)息，安排閩江流(liu)域的水(shui)口電站等(deng)發電站加(jia)大發電力度(du)(du)，降(jiang)低水(shui)庫(ku)庫(ku)容(rong)水(shui)位，騰出庫(ku)容(rong)，迎接即將到來的洪水(shui)，確保合理利(li)(li)用水(shui)資源，節水(shui)增發電。

福(fu)建(jian)省(sheng)(sheng)水(shui)電(dian)(dian)(dian)(dian)資源(yuan)開發程度高(gao)，水(shui)電(dian)(dian)(dian)(dian)站(zhan)數量眾(zhong)多，特別是(shi)閩(min)江流域水(shui)電(dian)(dian)(dian)(dian)站(zhan)群系(xi)統(tong)，27座(zuo)水(shui)電(dian)(dian)(dian)(dian)站(zhan)形(xing)成了以水(shui)口電(dian)(dian)(dian)(dian)站(zhan)為(wei)中(zhong)心、互(hu)為(wei)關聯的復雜系(xi)統(tong)，是(shi)我國(guo)目前(qian)水(shui)電(dian)(dian)(dian)(dian)調度最為(wei)復雜的省(sheng)(sheng)級電(dian)(dian)(dian)(dian)網(wang)水(shui)電(dian)(dian)(dian)(dian)系(xi)統(tong)之一。

根據福(fu)建(jian)水電資源的(de)特點和規律，國網(wang)福(fu)建(jian)電力(li)開發(fa)了福(fu)建(jian)電網(wang)大(da)(da)型水庫(ku)短期徑流預(yu)(yu)報調度系(xi)統(tong)，具備(bei)大(da)(da)型水庫(ku)短期徑流預(yu)(yu)報、大(da)(da)型水庫(ku)洪水調度、水庫(ku)洪水退水過(guo)程預(yu)(yu)報、水庫(ku)動(dong)態汛限水位洪水調度、天然來(lai)水還原計算及豐(feng)平枯評價(jia)功能。該公司(si)利(li)用(yong)該系(xi)統(tong)進行水庫(ku)群的(de)跨流域優(you)化(hua)調度，在(zai)大(da)(da)到(dao)暴雨到(dao)來(lai)之(zhi)前預(yu)(yu)先適當(dang)騰庫(ku)，在(zai)監視到(dao)明顯降雨之(zhi)后加大(da)(da)發(fa)電出力(li)，在(zai)監測(ce)到(dao)洪峰過(guo)后進行攔蓄洪尾，最(zui)大(da)(da)限度地優(you)化(hua)利(li)用(yong)水資源。

今年，福建電(dian)(dian)(dian)力調(diao)度(du)控制中(zhong)心在調(diao)度(du)受(shou)強降雨(yu)影響(xiang)形成的水(shui)口電(dian)(dian)(dian)站“20150723”雙(shuang)峰(feng)(feng)型(xing)洪水(shui)中(zhong)，主動協(xie)調(diao)省(sheng)防汛(xun)部門(men)，在不影響(xiang)防汛(xun)安全的前提下，利用水(shui)庫短期徑(jing)流(liu)預(yu)報(bao)調(diao)度(du)系統，通過(guo)采取(qu)洪前騰(teng)庫迎峰(feng)(feng)、洪峰(feng)(feng)過(guo)后攔(lan)蓄洪尾(wei)的調(diao)度(du)方式，并(bing)采取(qu)調(diao)停(ting)7臺火電(dian)(dian)(dian)機(ji)組、降低3臺核電(dian)(dian)(dian)機(ji)組出力、臨時(shi)增(zeng)(zeng)加150萬千瓦(wa)電(dian)(dian)(dian)力外送華東的電(dian)(dian)(dian)力平衡措施，為水(shui)電(dian)(dian)(dian)盡(jin)量多(duo)發騰(teng)出了空間，確(que)保了水(shui)口電(dian)(dian)(dian)站水(shui)庫棄水(shui)滿發率達(da)到(dao)100%，多(duo)發電(dian)(dian)(dian)量約(yue)5000萬千瓦(wa)時(shi)，增(zeng)(zeng)加了水(shui)電(dian)(dian)(dian)庫存電(dian)(dian)(dian)量1.4億(yi)千瓦(wa)時(shi)，節水(shui)增(zeng)(zeng)發電(dian)(dian)(dian)效益顯著。

“通過(guo)不斷創新，改善水(shui)電(dian)(dian)(dian)(dian)調(diao)(diao)(diao)度(du)方式，優化水(shui)火(huo)聯合(he)調(diao)(diao)(diao)度(du)，我們用同樣的水(shui)資(zi)源(yuan)創造了(le)更大的效(xiao)益，也達(da)到了(le)節能(neng)(neng)減(jian)排的效(xiao)果(guo)。”福(fu)建(jian)(jian)電(dian)(dian)(dian)(dian)力調(diao)(diao)(diao)度(du)控制中(zhong)心(xin)相關負(fu)責人(ren)表(biao)示，1～6月，該中(zhong)心(xin)加強水(shui)電(dian)(dian)(dian)(dian)發(fa)電(dian)(dian)(dian)(dian)調(diao)(diao)(diao)度(du)管理，密(mi)切跟蹤(zong)水(shui)庫來水(shui)和電(dian)(dian)(dian)(dian)網負(fu)荷變化情(qing)況，積(ji)極(ji)采取(qu)汛前、洪前發(fa)電(dian)(dian)(dian)(dian)騰庫及(ji)攔蓄洪尾，合(he)理安(an)排梯(ti)級水(shui)電(dian)(dian)(dian)(dian)廠檢修，減(jian)少水(shui)庫棄(qi)水(shui)；當(dang)可能(neng)(neng)出現棄(qi)水(shui)時(shi)，通過(guo)調(diao)(diao)(diao)停火(huo)電(dian)(dian)(dian)(dian)機組、降低火(huo)電(dian)(dian)(dian)(dian)出力、抽蓄電(dian)(dian)(dian)(dian)站調(diao)(diao)(diao)峰等措(cuo)施(shi)，優先讓水(shui)電(dian)(dian)(dian)(dian)等清(qing)潔能(neng)(neng)源(yuan)多(duo)發(fa)電(dian)(dian)(dian)(dian)，確(que)保(bao)了(le)水(shui)電(dian)(dian)(dian)(dian)全額消納(na)，棄(qi)水(shui)損(sun)失電(dian)(dian)(dian)(dian)量(liang)為(wei)零。上(shang)半年，福(fu)建(jian)(jian)電(dian)(dian)(dian)(dian)網調(diao)(diao)(diao)度(du)口徑水(shui)庫節水(shui)增(zeng)發(fa)電(dian)(dian)(dian)(dian)量(liang)達(da)8.42億千(qian)瓦(wa)時(shi)，水(shui)電(dian)(dian)(dian)(dian)水(shui)能(neng)(neng)利用率提(ti)高9.94%。
