摘　　要：本文针对具有引水隧道、调压井、共管带岔管的复杂水轮机引水系统,提出引入附加输入的方法,将调压井子系统动态处理为系统的附加输入,以降低系统的阶数;将一管多机的水力耦合解耦为附加输入,以降低系统的复杂性和应用的难度.通过引入附加输入,将复杂的水力系统描述为:以等效管参数表示的单机单管标准型式+附加输入.结合实例的仿真表明,本文所提出的方法是合理的.该方法为简化更为复杂的水轮机水力系统控制模型的设计提供了一种新的思路.A method of introducing additional input is proposed to deal with complex conduit system of hydro turbine,including tunnel,surge tank and sharing common conduit.To reduce orders of the hydraulic system,the hydraulic transient of surge tank subsystem is dealt with an additional input;and to reduce the complexity of hydraulic system and difficulty in application,the hydraulic coupling with sharing common conduit is decoupled into multi additional inputs.By introducing additional input,the complex hydraulic system is described as one penstock one machine standard system expressed as equivalent parameters plus additional input.The results of actual simulated application show that the method proposed in this paper is reasonable.This method gives a new way to simplify the designing of control model of hydro turbine for more complex hydraulic system.
