摘要
本文针对水轮机调速机构存在的间隙特性在其精确数学描述的基础上,通过数字仿真,从理论上研究了间隙特性对文[1]中提出的自校正Robust水轮机调速系统的影响。结果表明,间隙特性将降低系统的性能。从而指出,设计适应式水轮机调速器时,应把间隙特性考虑进去。本文还提出了改进的自校正Robust水轮机调速器。
Directed against backlash existing in hydro-turbine speed governing system, and based on mathematical description of backlash, this paper studies through digit simulation the innfluence of backlash on STR robust hydro-turbine speed governing system presented in [1]. Simulation results show that backlash declines the performance of the systems. It is pointed out that backlash must be taken into consideration when designing adaptive hydro-turbine Speed govrnor. At last, this paper presents improved STR-R hydro-turbine speed governor.
