正孔水电站工程水轮发电机组的选型分析

Analysis on Hydro Turbine Type Selection for Zhengkong Hydropower Stationt-A Small Hydropower Project in Place of Fuel

小水电代燃料项目正孔水电站位于贵州省正安县安场镇正江村,为芙蓉江左岸一级支流三江河干流上水电梯级规划的第六级电站,距正安县城22 km,距县安场镇11 km。正孔水电站坝址以上流域面积1 030 km2,厂址布置在河道右岸距离大坝下游250 m处,距上游已建的瓮溪水电站厂址约9.4 km,距下游已建的螺丝塘水电站坝址约2.9 km。现右岸距离河床约100 m高差处有简易公路通往,交通条件一般。该水电站为混合式电站,主要任务是水力发电。文章对电站工程水轮发电机组的选型进行了比较分析。

Zheng＆#39;an Hydropower station is located in the Zhengjiang village,Anchang Town,Zheng＆#39;an County,Guizhou Province,the sixth hydropower station on the Sanjianghe River mainstream,which is the first tributary of the Furongjiang river,1 1 km away from Anchang Town,22 km away from Zheng＆#39;an Town,.The catchment area over the dam 1 030 km2,powerhouse is located in downstream of the dam on the right bank,250 m from the dam,about 9.4 km away from upstream existing Wengxi hydropower station,2.9 km away from the existing Siluotang hydropower station.There is a simple road at the right bank of river bed,elevation distance about 100 m,the traffic conditions is not good.The hydroelectric station is a hybrid power plant;the main task is to hydroelectric power.The selection of power plant turbine generator unit is analyzed in the paper.
