Abstract
In order to meet power grid’s requirement of primary frequency regulation (PFR) of hydropower unit, we analyze the typical problems and influencing factors of PFR , and present a method of optimizing the PFR perform -ance of hydropower unit.The method of optimizing PID parameters of hydraulic turbine governor is analyzed in de -tail.We propose to adjust the PID parameters according to the range of the deviation , and to change the dead band of the PFR calculation.Furthermore, we put forward some suggestions for PFR and AGC (Automation generator control) coordination control.Power regulation mode used as a priority control mode could guarantee the coordina -tion between PFR and AGC.Through hardware modification and internal program of governor , the PFR performance is optimized and improved.The method is applied to a hydropower unit of 600MW for verification, and the result suggests that the PFR performance is improved .关键词
