摘　　要：提出了基于轨迹灵敏度的方法来研究水电系统参数及初始运行状态不确定性对水电系统动态安全的影响。研究建立水机电联合系统动态模型及其轨迹灵敏度模型,通过水电系统动态过程对其控制系统参数及初始运行状态的灵敏度来分析其参数及初始运行状态对整个水电系统动态过程的影响,提出对系统安全运行较大的参数及初始运行状态特点、参数的安全调整范围。This paper proposes application of the trajectory sensitivity method in the investigation of the effects of hydropower parameters and instability of the initial operation conditions on the dynamic security of the hydropower system. Through researches, the paper sets up a combined hydro-mechanical-electro dynamic model and its trajectory sensitivity model by simulation. Through applications of the method in analyzing the parameters of the control system and the initial conditions and their effects on the entire hydropower system, it proposes the larger parameters, features of the initial operation and the adjustment range of parameters which have larger effects on the safety operation of the system.
