摘　　要：白鹤滩水库蓄水后将淹没原以礼河四级水电站的尾水系统、开关站、地下厂房、球阀室等设施。为利用剩余发电水头,以礼河四级水电站复建工程将沿用原首部枢纽、引水上平洞、调压室等建筑物,新建压力管道、地下厂房、尾水系统、地面出线场、业主营地等,复建后总装机容量为130MW,采用4台立轴冲击式水轮发电机组。该工程引水发电系统为新老结合的工程,尤其是沿用了原调压室及采用了冲击式机组更加剧了电站运行调节保证的复杂性,主要对所假定的工况进行调节保证计算,并对真机甩负荷进行复核,确保整个工程的运行安全。After reservoir impounding,Baihetan Reservoir will submerge tailrace system,switch station,underground power house,ball valve room and other facilities of Yilihe Fourth Cascade Hydropower Station.In order to utilize the remaining generation head,the original Headrace complex,diversion level tunnel,surge chamber and other structures will be used in Yilihe Fourth Cascade Hydropower Station Reconstruction Project,and new penstock,underground power house,tailrace system,ground outlet yard,owner's camp,etc.will be built.After reconstruction,the total installed capacity is 130MW,and 4 vertical-shaft impact hydraulic generator units are used.The water diversion and power generation system of this project is a combination of old and new projects,especially the original surge chamber and impact unit are used,which aggravates the complexity of operation regulation guarantee of power plant.In this paper,the assumed conditions are adjusted to ensure calculation,and the load rejection of real machine is checked to ensure the operation safety of the whole project.
