坝式水电厂或称坝库式、堤坝式、蓄水式水电厂,是水电开发的基本方式之一。坝式水电厂是由河道上的挡水建筑物壅高水位而集中水头的水电厂。当水头不高且河道较宽时,用厂房作为挡水建筑物的一部分,这类水电厂又称河床式水电厂,也属于坝式水电厂。
坝式水电厂的发电厂房有坝后式、坝内式、溢流式、岸边式、地下式和河床式几种类型。[1]
引水式水电厂
引水式水电厂是水电开发的基本形式之一。这类水电,宜建在河道坡降较陡的河段或大河湾处,在河段上游筑坝引水,用引水渠道、隧洞、压力水管等将水引到河段下游,用以集中水头发电。这类水电厂大都为高水头水电厂。跨流域引水发电的水电厂必然是引水式水电厂。
混合式水电厂
混合式水电厂或称水库引水式水电厂,这类水电厂由挡水建筑物和引水系统共同集中发电水头,并由水库调节径流发电。
径流式水电厂
式水电厂,是在河道中拦河筑低坝或闸,基本不调节径流,靠天然径流发电的水电厂。当来水流量大于水轮机过水能力时,水电厂满出力运行,多余水量经泄水建筑物直接泄向下游,称为弃水;当来水流量小于水轮机过水能力时,则有部分发电机组容量来被利用。水电厂的这种运行方式称为径流发电。[1]
梯级水电厂
梯级水电厂是分布在一条河流上下游有水流联系的水电厂群,其各级水电厂可以是坝式、引水式或混合式水电厂等不同类型。各类水电厂都有各自的优缺点,建设梯级水电厂可以互相取长补短,取得提高资源利用率,协调水资源综合利用之间的矛盾,缩短总工期,减少总投资等梯级效益。
抽水蓄能电厂
抽水蓄能电厂建有上下两座水库,其间用压力隧洞或压力水管相连接。它是利用电力系统低谷负荷时的剩余电力从下库抽水雷存到上库,在高峰负荷时从上库放水至下库发电的水电厂。
