| 摘 要： | 结合某电站供水系统所构成的复杂的输水发电系统,为了保证其稳定性和经济性,在系统尾部需要采用设置阀门调节方式。通过详细的数值计算分析,探讨了不同的阀门调节方式对系统稳定性的影响。根据该电站的特殊问题,尾水调压室的水位和阀门的引用流量要求能够尽快达到目标值,提出了分区调节方式,以较简单的控制模式实现了比较复杂的调节目标。

| Abstract: | There is a hydropower station,and its tailrace tunnel is a water supply system.A set of valves will be set on the end of the water supply tunnel in order to assure the stability and economical efficiency of the water conduits system.By the detailed numerical calculation,the effect of the variable regulating method on the stability of the system has been studied.According to the particularity of the hydropower station,the surge tank water level and the valve discharge must be getting to the target value as quickly as possible, a"partitioning control model"is proposed,which can realize complex regulating objectives with a simple control model. |

| Keywords: | hydropower station stability of system valve regulating partitioning control model numerical calculation |
