调压室作为压力引水系统利用室内自由水面反射水锤波,限制水锤波进入引水道,减小压力水管及水轮机的水锤压力。改善水轮机在负荷变化时的运行条件及系统供电质量。其体型尺寸确定的是否合适对压力引水系统以后运行的稳定性影响很大,西花水电站在调压室设计过程中采用解析法初步确定调压室体型尺寸后并委托科研单位对引水系统进行了水力过渡过程计算,进一步优化了调压室的体型尺寸。 The pressure regulating room, as a pressure water diversion system, uses the indoor free water surface to reflect the water hammer wave, restricting the water hammer wave from entering the diversion channel and reducing the water hammer pressure of the pressure water pipe and the turbine. Improve the turbine operating conditions in the load changes and the quality of the system power supply. Whether its size and shape are suitable for the future operation of pressure diversion system has a great impact on the stability of the West Hydropower Station in the design process of the surge chamber by the analytical method to determine the size of the surge chamber body size and entrusted scientific research units of the diversion system Hydraulic transition process calculation, to further optimize the body size of the surge chamber.
