轮叶导叶并列动作数字控制系统的稳定性

Stability of Digital Control System of Kaplan Turbine Considering the Runner Blade in Parallel With Gate

本文针对转桨式水轮机电液调节装置的发展趋势-微机调速、数字协联,建立了轮叶导叶随动系统并列动作时水轮机数字控制系统的数学模型,并通过稳定分析给出了系统的稳定域.文中还与连续系统的稳定域进行了对比,得到了一些有益的结论.

In accordance with the trend in the development of electro-hydraulic governor of Kaplan turbine, i.e. the microprocessor-based governor, this paper present a mathe-matical model considering the regulation of runner blade servo system in parallel with that of the gate. The Stability ranges of digit as well as analogous control system have been given. And then, some useful conclusions were drawn.
