摘　　要：在有压引水式发电站中,调压室的设计是工程中的重点及难点,其选型和结构布置直接关乎工程运行的稳定和投资。本文以昭通油房沟水电站调压室设计为例,分析该工程区地形地质条件,对调压室的型式和结构布置进行设计,通过技术可行性和经济合理性两方面对比研究,最终选择阻抗式带上室方案。工程建成投运至今,运行工况良好,可为其他有压长引水系统调压室设计提供参考。The design of the pressure regulating chamber is the key and difficult point of the project in the pressurized water diversion power station. Its model selection and structure layout are directly related to the stability and investment of project operation. The design of Zhaotong Youfanggou Hydropower Station Pressure Regulating Chamber is adopted as an example in the paper for analyzing topography and geological conditions of the project,model selection and structure layout of the surge chamber are analyzed,the impedance upper room plan is finally chosen through the comparative study on the two aspects of technical feasibility and economic rationality. Since the project is completed and put into operation,the operation condition is good. It can provide references for designing pressure regulating chamber of other pressurized long water diversion system.
