摘　　要：地下厂房渗漏、检修、事故排水设计是关乎电站安全运行的一项重要内容。抽水蓄能电站机组吸出高度大,安装高程低,往往难以做到全自流排水,需要抽排。本文从方案设计、运行管理、安全性等多方面进行了计算论证,优化了宁海抽水蓄能电站地下厂房排水设计方案,提高了经济性,最大限度保证地下厂房运行安全。Leakage,maintenance and accident drainage design of underground powerhouse is an important content related to the safe operation of power station.Because of the high suction height and low installation elevation of the pumped storage power station,it is often difficult to achieve full gravity drainage,which requires pumping.In this paper,from the aspects of scheme design,operation management and safety,the calculation and demonstration are carried out,and the drainage design scheme of the underground powerhouse of Ninghai pumped storage power station is optimized,which improves the economy and ensures the operation safety of the underground powerhouse to the maximum extent.
