一、概況
茶林河水(shui)(shui)(shui)電站(zhan)位于湖(hu)南省(sheng)慈利縣境內的(de)澧水(shui)(shui)(shui)中(zhong)(zhong)游,是經(jing)中(zhong)(zhong)華人民(min)共(gong)和國(guo)(guo)國(guo)(guo)家計(ji)委和水(shui)(shui)(shui)利部(bu)批準的(de)《澧水(shui)(shui)(shui)流(liu)域規劃報告(gao)》中(zhong)(zhong)梯(ti)級開發的(de)重點項目之一。湖(hu)南省(sheng)也一直將其作(zuo)為重點,并列入了“九五(wu)”與2010年發展規劃。壩址以上控(kong)制流(liu)域面(mian)積11642km2,占澧水(shui)(shui)(shui)總流(liu)域面(mian)積18583km2的(de)62.6%。
茶林河水電站以發電為主,水庫正常蓄水位81m,相應庫容0.242億m3,有效庫容0.114億m3,采用貫流式水輪發電機組,裝機3臺,總裝機容量72MW,保證出力1.09萬KW,年發電量2.8億KW.h,并入湖南省電網運行。壩址地質條件簡明,施工條件好,特別是上游有江埡、魚潭水庫的調節作用,經濟指標好,是湖南省水力資源開發的最佳電源點之一。
茶(cha)林河水(shui)電(dian)(dian)(dian)(dian)站(zhan)工程位于湘南張(zhang)家界市慈(ci)利(li)縣境內的(de)澧水(shui)中游,是澧水(shui)干流(liu)(liu)規(gui)劃確定的(de)第13梯級電(dian)(dian)(dian)(dian)站(zhan),上(shang)距(ju)城關電(dian)(dian)(dian)(dian)站(zhan)(慈(ci)利(li)縣城)15km,下距(ju)三江(jiang)口電(dian)(dian)(dian)(dian)站(zhan)約30km。總(zong)庫(ku)容1.29億立方米,壩址以(yi)上(shang)控制流(liu)(liu)域面(mian)(mian)(mian)積(ji)11642平方公里,占澧水(shui)總(zong)流(liu)(liu)域面(mian)(mian)(mian)積(ji)的(de)62.6%,裝機(ji)3×1.8萬千瓦,電(dian)(dian)(dian)(dian)站(zhan)裝設3臺(tai)型號為(wei)GZ995a-WP-530、SFWG18-64/6220燈泡貫(guan)流(liu)(liu)式水(shui)輪發電(dian)(dian)(dian)(dian)機(ji)組(zu)。該水(shui)電(dian)(dian)(dian)(dian)站(zhan)的(de)建(jian)成,除具有滯洪和(he)防(fang)洪功(gong)能(neng)外(wai),還可(ke)以(yi)增加耕(geng)地(di)面(mian)(mian)(mian)積(ji)和(he)水(shui)產(chan)(chan)養殖面(mian)(mian)(mian)積(ji),促進農(nong)林生產(chan)(chan)和(he)水(shui)產(chan)(chan)養殖,緩和(he)湘西(xi)北地(di)區(qu)供電(dian)(dian)(dian)(dian)矛盾。
