中文摘要	为了提高大型水轮机组远距离输电的安全稳定性,在具有刚性水锤的一类水轮发电机的综合非线性模型的基础上,根据非线性微分几何控制理论,提出了新的调节输出设计法。该方法可以克服现有调速器非线性控制面临的零动态设计瓶颈,从而推导出调速器的一种新型非线性控制律——综合非线性调速器控制器(CNGC)。同时,论证了理想水轮机模型是该综合非线性模型在额定运行点线性化近似的结果。数字仿真实验表明,所提出的CNGC不但效果远好于常规控制律,而且优于现有的基于理想水轮机模型推导的非线性控制律(GNOPSS)。; In order to enhance the stability of the long-distance electricity transmission system for large hydraulic turbine generators, on the basis of the comprehensive nonlinear model (CNM) with the assumption of the non-elastic water hammer for the hydraulic turbine, a new kind of output regulation design method is suggested by means of nonlinear geometric control theory, which can overcome the difficulties caused by zero-dynamics design problem. From this new output regulation design method, a novel governor control strategy is constructed, and in addition, it is verified that ideal hydraulic turbine model is a kind of linearization of the CNM at a rating operation point. The digital simulations are carried out on a simple power system and the results verify that the performance of the suggested strategy is much better than not only the conventional control laws but also the exiting nonlinear control law from the ideal hydraulic turbine model.; 国家自然科学基金资助项目(59837270,50377018) 国家电力公司重大科技项目(SPKJ008-05)。~~
