对水轮发电机组一次调频控制系统的动、静态特性进行了深入分析，指出了该控制系统在功率闭环模式下存在的问题，提出了开环模式的控制方案，通过在控制系统中引入开度→功率非线性反馈，这种新的方案显示出与其它开度控制类似的对电网频率的快速响应，同时它可以达到与功率闭环控制相当的单位目标功率的控制精度。
This paper presents a thorough analysis on the dynamic and static characteristics of the primary frequency regulation control system of hydro generator units.The analysis shows the problems of the control system at the power closed-loop mode,and thus a control scheme of open-loop mode is put forward.By introducing the opening→power nonlinear feedback into the control system,this new scheme shows a fast response to the grid frequency similar to the other opening controls,while it can reach a control accuracy of units aim-power comparable to the power closed-loop control.
