中文摘要：
研究具有共用管段水力系统的耦合问题,提出水力耦合分解成多个仅依赖于各自管段流量的单变量函数的解耦方法,以解决水力耦合带来的复杂性和困难。将传递函数描述的弹性水击水力动态转化为相对值形式的微分方程模型,与主接力器运动方程构成水轮机的微分方程模型。解耦后的其他管段的耦合作用以附加输入扰动的形式出现在水轮机模型中,实现输入的解耦,可有效简化控制器的设计。仿真表明,所提出的解耦方法是有效的。
英文摘要：
Studying on the hydraulic coupling with sharing common conduit,a decoupling method was proposed to reduce its complexity and difficulty in application due to hydraulic coupling,that the hydraulic coupling was approximately decomposed into multi function depending on each penstock flow.The hydraulic dynamics with elastic water column was converted from transfer function to differential equations in relative value,and differential equations model of hydro turbine was composed by connecting it with motion equation of main servomotor.Those couplings of another penstocks obtained by decoupled were taken as additional disturbance in hydro turbine model,which input control was decoupling in this way,and simplify the controller design.The simulation results show that proposed decoupling model is effective.
