摘　　要：气垫式调压室是一种性能优越的涌浪控制及防止水力振动调压方案,与常规调压室相比具有投资低,工期短,利于环保等优势。调节保证设计是评价水电站气垫式调压室输水发电系统技术经济合理性的重要研究内容之一。本文以西藏地区某水电站为例,开展了水电站气垫式调压室大波动、小波动调节保证设计仿真计算,分析了主要控制参数变化规律,根据计算结果对输水发电系统安全性和各项调节保证设计参数作出评价。The air cushion surge chamber is a kind of superior performance system to control and prevent the hydraulic vibration. Compared with conventional surge chamber, the air cushion surge chamber has advantages of reducing investment, shortening the construction period, environmental protection and so on. Simulation calculation of adjusting the guarantee design is one of the important research contents of economic and technological rationalities for water delivering and power generating system of hydropower station. Taking the example of a hydropower station in Tibet area, this paper has carried out big fluctuation, small fluctuation adjustment guarantee design simulation of air cushion surge chamber, and analyzed changing rule of the main control parameters. According to the calculation results, water power system security and various parameters of adjustment guarantee design are evaluated.
