摘　　要：调压室的设置位置是水电站引水系统设计的重点内容,不仅关系到工程造价,而且会对电站过渡过程调节保证参数产生影响。基于水力过渡过程的数学模型,对某电站引水系统三种布置方案进行了数值模拟,结果表明:在引水系统不是很长的情况下,适当增大引水隧洞以及压力管道的直径来改善调节保证参数是可行的;调压室越趋近于临界位置,对调节保证参数越有利,但调压室涌浪会有所增加。The location of the surge tank is definitely the top concern in the diversion system design in hydropower station.Because it not only relate to the construction cost,but also effects the guaranteed regulations in transient process of power station.Based on the mathematic model of hydraulic transient process,three diversion system schemes were numerical simulated.The results show that it is feasible to enlarge the diameters of diversion tunnel and penstock properly for improving the guaranteed regulations when diversion system is not too long.And more closer to the critical position the surge tank is,more favorable to guaranteed regulations,but the chamber surge would increase.
