1、摘 要丰宁抽水蓄能电站位于河北省承德市丰宁满洲自治县,电站以正在建设中的丰宁水电站水库为下水库,上水库位于永利村滦河左岸灰窑子沟顶端。枢纽总体建筑物由上水库、输水系统、下水库、地下厂房系统及地面出线场和开关站等部分组成。电站总装机 175万千瓦,共六台机,每台29万千瓦。水库枢纽工程包括: 钢筋混凝土面板堆石坝、放空隧洞、 进 / 出水口、环库公路 。本电站引水系统较长,尾水系统较短,经比较选择引水和尾水系统均采用一管三机的布置方式。经计算, 引水系统需设置调压井。水道系统由引水系统和尾水系统两部分组成。引水系统建筑物包括 : 上水库进 / 出水口、引水隧洞、引水调压井、高压管道、岔管和高压支
2、管。 尾水系统建筑物包括 : 尾水支洞、尾水事故闸门室、尾水隧洞和下水库进 / 出水口等。上水库进 / 出水口采用岸边侧式进 / 出水口 , 布置于左坝肩上游库岸 , 前沿设有拦污栅和防涡梁 , 其后布置有事故闸门井及启闭机房。电站采用中尾部开发方式 , 地下厂房洞室群布置在粗粒花岗岩层内。AbstractAbundant rather pumps water gathers can the power plant be located the Hebei Province Chende abundant rather Manchu Autonomous County, the power p
