山西垣曲抽水蓄能电站输水系统设计

Design of water transmission system for Shanxi Yuanqu pumped storage power station

山西垣曲抽水蓄能电站装机4×300 MW,额定水头457 m,在系统中承担调峰、填谷、储能、调频、调相和紧急事故备用等任务,保证电网的安全、稳定、经济运行。文章对该抽水蓄能电站输水系统的工程地质条件、输水系统布置以及进/出水口、引水调压室、尾水调压室、压力管道钢衬段及其排水设计做了介绍,可为类似工程设计提供参考。

Shanxi Yuanqu pumped storage power station has an installed capacity of 4×300 MW and a rated water head of 457 m.In the system,it undertakes the tasks of peak and valley filling,energy storage,frequency and phase modulation and emergency standby to ensure the safe,stable and economic operation of the power grid.The paper introduces the engineering geological conditions,the layout of the water transmission system,the inlet/outlet,the diversion surge chamber,the tailwater surge chamber,the steel lining section of the pressure pipeline and its drainage design of the pumped storage power station,which can provide reference for the similar engineering design.
