工程概況

風灘水電(dian)站(zhan)(zhan)(zhan)工程位于(yu)四川省平(ping)(ping)昌縣(xian)巴河大(da)風灘處，距平(ping)(ping)昌縣(xian)城11km，與雙(shuang)灘水電(dian)站(zhan)(zhan)(zhan)構成(cheng)巴河流(liu)域梯級電(dian)站(zhan)(zhan)(zhan)。電(dian)站(zhan)(zhan)(zhan)于(yu)70年(nian)代(dai)末建(jian)(jian)成(cheng)，為漿砌石溢流(liu)壩(ba)，壩(ba)高(gao)17.56m，裝(zhuang)機容量為2×3.2MW。本次擴建(jian)(jian)工程在原電(dian)站(zhan)(zhan)(zhan)大(da)壩(ba)基(ji)礎上加(jia)壩(ba)4m，在原廠房(fang)(fang)左側新建(jian)(jian)廠房(fang)(fang)，新增裝(zhuang)機2×9.0MW，擴建(jian)(jian)后電(dian)站(zhan)(zhan)(zhan)總裝(zhuang)機24.4MW。

建設過程

鳳灘電(dian)站(zhan)(zhan)擴建(jian)(jian)和(he)技(ji)改(gai)工程：鳳灘水電(dian)站(zhan)(zhan)位于雙灘電(dian)站(zhan)(zhan)下游(you)28km的(de)巴(ba)河干(gan)流上(shang)，電(dian)站(zhan)(zhan)為70年(nian)(nian)代(dai)末(mo)建(jian)(jian)成的(de)一座小型水電(dian)工程，電(dian)站(zhan)(zhan)規劃(hua)裝機(ji)4臺(tai)，實際(ji)裝機(ji)2臺(tai)，裝機(ji)容量6.4MW，年(nian)(nian)發(fa)電(dian)量4200多萬kwh。隨著(zhu)上(shang)游(you)電(dian)站(zhan)(zhan)的(de)開工建(jian)(jian)設，為充分利用(yong)上(shang)游(you)電(dian)站(zhan)(zhan)水庫(ku)庫(ku)容的(de)調節作(zuo)用(yong)，采取(qu)對(dui)電(dian)站(zhan)(zhan)進行擴建(jian)(jian)和(he)機(ji)組改(gai)造(zao)。風灘電(dian)站(zhan)(zhan)擴建(jian)(jian)工程為在(zai)原電(dian)站(zhan)(zhan)大壩基礎上(shang)加壩4m，電(dian)站(zhan)(zhan)正常(chang)蓄(xu)水位288.2m，新增電(dian)力裝機(ji)18MW，年(nian)(nian)發(fa)電(dian)量8500多萬kwh，電(dian)站(zhan)(zhan)擴建(jian)(jian)概算總投(tou)資1.637億(yi)元，實際(ji)完成各項投(tou)資近2億(yi)元。風灘電(dian)站(zhan)(zhan)技(ji)改(gai)工程為在(zai)現有水工建(jian)(jian)筑不變基礎上(shang)將現2×3.2MW機(ji)組技(ji)術改(gai)造(zao)為2×5MW，技(ji)改(gai)概算總投(tou)資為2700多萬元。
