摘要
汽轮发电机组的负荷控制特性，特别是它在甩负荷情况下的动态响应，是机组运行指导和科学研究中尤为引人关注的问题．为此，针对我国引进型３００ＭＷ汽轮发电机组数字电一液控制系统，建立其负荷控制的动态数学模型，在对此进行数字仿真研究的基础上，提出了这一系统在甩负荷状态下的动态响应特性和仿真结果的分析结论．
During parallel operation of a turboalternator on the power grid,the load control systemplays a constant role,The load control characteristics,especially the dynamic response in thecase of load throw-off for a turboalternator,are problems of very great public concern in theanalysis of the operating state,the calculation of shaft torsional vibration,the investigationon the interaction between electrical and mechanical systems,and the system parameter ad-justment and function improvement.A dvnamic mathematical model for load control hasbeen developed to simulate the digital electro-hydraulic control system in an imported 300MW turboalternator. On the basis of digital simulation study,some analytic conclusions onthe dynamic response characteristics during load throw-off are given.
