重点论述了混流式和轴流定桨式水轮机的动态特性。文中首先给出了水轮机调节系统的一种新稳定域图,应用该图分析了调速器和调节对象参数对稳定域的影响。业已证明,Hovey和S.Hagihara所研究的稳定域图仅是本文当e_n=0和理想水轮机条件下新稳定域图的一不特例。文中讨论了调速器参数对调节品质的影响,研究了几种真实水轮机的动态特性,并给出了三种典型水轮机的最优运行区。
The dynamic characteristics of Francis turbine and Axial-flow propeller turbine are mainly discussed. In this paper, a new stable region graph of turbine governing system is given first. The influence of the governor and the parameters of the tuning object on the stability region is analyzed. It has been shown that the stable domain graph studied by Hovey and S. Hagihara is only a non-specific example of the new stable domain graph when e_n = 0 and ideal turbine conditions. In this paper, the effect of governor parameters on adjusting quality is discussed. The dynamic characteristics of several real hydraulic turbines are studied. The optimal operation zones of three typical hydraulic turbines are given.
