8月6日，在國網福建省電(dian)(dian)力有限公司調控中(zhong)心，水(shui)(shui)情(qing)調度人員根據(ju)氣象部門預(yu)報(bao)的(de)第13號臺風“蘇迪(di)羅”降(jiang)雨信息(xi)(xi)，利用(yong)福建電(dian)(dian)網大(da)型水(shui)(shui)庫短期徑(jing)(jing)流(liu)預(yu)報(bao)調度系統(tong)顯示的(de)水(shui)(shui)庫短期徑(jing)(jing)流(liu)預(yu)報(bao)信息(xi)(xi)，安排閩江流(liu)域(yu)的(de)水(shui)(shui)口(kou)電(dian)(dian)站等發電(dian)(dian)站加大(da)發電(dian)(dian)力度，降(jiang)低水(shui)(shui)庫庫容水(shui)(shui)位，騰出庫容，迎接即將到來的(de)洪(hong)水(shui)(shui)，確保合理(li)利用(yong)水(shui)(shui)資源，節水(shui)(shui)增發電(dian)(dian)。

福建省(sheng)水(shui)(shui)(shui)(shui)電(dian)資源開發程度高，水(shui)(shui)(shui)(shui)電(dian)站(zhan)數量眾多(duo)，特別是閩江流(liu)域(yu)水(shui)(shui)(shui)(shui)電(dian)站(zhan)群系(xi)統(tong)，27座(zuo)水(shui)(shui)(shui)(shui)電(dian)站(zhan)形成了以水(shui)(shui)(shui)(shui)口電(dian)站(zhan)為(wei)中心(xin)、互(hu)為(wei)關聯(lian)的復雜系(xi)統(tong)，是我國目前水(shui)(shui)(shui)(shui)電(dian)調度最為(wei)復雜的省(sheng)級電(dian)網水(shui)(shui)(shui)(shui)電(dian)系(xi)統(tong)之一。

根據福(fu)(fu)建(jian)水(shui)(shui)(shui)(shui)(shui)電資(zi)源的特點和規(gui)律，國網(wang)福(fu)(fu)建(jian)電力開發了福(fu)(fu)建(jian)電網(wang)大(da)(da)(da)型水(shui)(shui)(shui)(shui)(shui)庫(ku)短(duan)期(qi)徑流預報(bao)(bao)調度(du)系(xi)統(tong)，具備大(da)(da)(da)型水(shui)(shui)(shui)(shui)(shui)庫(ku)短(duan)期(qi)徑流預報(bao)(bao)、大(da)(da)(da)型水(shui)(shui)(shui)(shui)(shui)庫(ku)洪(hong)水(shui)(shui)(shui)(shui)(shui)調度(du)、水(shui)(shui)(shui)(shui)(shui)庫(ku)洪(hong)水(shui)(shui)(shui)(shui)(shui)退(tui)水(shui)(shui)(shui)(shui)(shui)過程預報(bao)(bao)、水(shui)(shui)(shui)(shui)(shui)庫(ku)動態汛(xun)限水(shui)(shui)(shui)(shui)(shui)位洪(hong)水(shui)(shui)(shui)(shui)(shui)調度(du)、天(tian)然來(lai)水(shui)(shui)(shui)(shui)(shui)還原計算及豐(feng)平(ping)枯評價(jia)功能(neng)。該公司利用該系(xi)統(tong)進行(xing)水(shui)(shui)(shui)(shui)(shui)庫(ku)群的跨流域優化調度(du)，在大(da)(da)(da)到暴雨到來(lai)之(zhi)前預先(xian)適當騰庫(ku)，在監(jian)視(shi)到明顯降雨之(zhi)后加大(da)(da)(da)發電出力，在監(jian)測到洪(hong)峰過后進行(xing)攔蓄洪(hong)尾，最大(da)(da)(da)限度(du)地(di)優化利用水(shui)(shui)(shui)(shui)(shui)資(zi)源。

今年，福(fu)建電力(li)調(diao)(diao)(diao)度(du)(du)(du)控制(zhi)中心(xin)在調(diao)(diao)(diao)度(du)(du)(du)受強(qiang)降(jiang)雨(yu)影響形成的水(shui)(shui)(shui)(shui)口電站(zhan)“20150723”雙峰型(xing)洪(hong)(hong)水(shui)(shui)(shui)(shui)中，主動(dong)協調(diao)(diao)(diao)省防(fang)汛部門，在不(bu)影響防(fang)汛安全的前提下，利用水(shui)(shui)(shui)(shui)庫(ku)短(duan)期徑流預報(bao)調(diao)(diao)(diao)度(du)(du)(du)系統，通過采(cai)取洪(hong)(hong)前騰(teng)(teng)庫(ku)迎(ying)峰、洪(hong)(hong)峰過后攔蓄洪(hong)(hong)尾(wei)的調(diao)(diao)(diao)度(du)(du)(du)方式，并采(cai)取調(diao)(diao)(diao)停7臺火電機(ji)組、降(jiang)低3臺核電機(ji)組出(chu)力(li)、臨時增(zeng)加150萬千(qian)瓦電力(li)外送華東的電力(li)平(ping)衡(heng)措施，為水(shui)(shui)(shui)(shui)電盡量(liang)多(duo)發(fa)騰(teng)(teng)出(chu)了(le)空(kong)間，確(que)保了(le)水(shui)(shui)(shui)(shui)口電站(zhan)水(shui)(shui)(shui)(shui)庫(ku)棄水(shui)(shui)(shui)(shui)滿(man)發(fa)率(lv)達到(dao)100%，多(duo)發(fa)電量(liang)約5000萬千(qian)瓦時，增(zeng)加了(le)水(shui)(shui)(shui)(shui)電庫(ku)存(cun)電量(liang)1.4億(yi)千(qian)瓦時，節水(shui)(shui)(shui)(shui)增(zeng)發(fa)電效益顯著。
