天荒坪抽水蓄能电站枢纽布置

The general layout of Tianhuangping Pumped storage Power Station

天荒坪抽水蓄能电站位于浙江省安吉县境内，距杭州５７ｋｍ，接近华东电网的负荷中心。电站上下库主要挡水建筑物均为土石坝，电站采用２条斜井式钢筋混凝土衬砌的高压管道，每条高压管道通过钢筋混凝土岔管接３根钢衬高压管道，引水进入机组。电站的主副厂房、主变洞、母线道、尾水闸门洞、通风和５００ｋＶ电缆竖井等建筑物均布置于地下洞室群中。５００ｋＶ开关站、地面ＧＩＳ室及中控楼等布置于下库左岸进／出水口３５０．２ｍ高程平台上。电站安装６台立轴单级可逆混流式水泵水轮机，发电电动机为立轴悬式、空冷、可逆式三相同步电机。电站以５００ｋＶ一级电压接入华东电网。

The Tianhuangping Pumped storage Power Station is located in An'ji county, Zhejiang province, 57 km away from Hangzhou City, close to the load center of East China Power Network The retaining structures of the upper and lower reservoirs of Tianhuangping Pumped storage Power Station are earth rock dam The station has two inclined shaft type penstocks with reinforced concrete lining Each penstock connects three steel lined penstocks through reinforced concrete bifurcated pipe, which diverts water into the power generating unit The structures, such as main and auxiliary power house, main transformer chamber, busbar gallery, tailwater gate chamber, ventilation and 500 kV cable shaft, are all arranged in the underground chamber group The 500 kV switchyard, ground GIS room and the central control building are arranged in a platform with an elevation of 350 2 m in the left inlet/outlet of the lower reservoir The station has 6 vertical axis single stage reversible mixed flow pump turbines The power generator is a type of vertical axis suspension, air cooling, reversible, three phase synchronous generator The station connects with East China Power Network by a voltage of 500 kV level
