Abstract: Dual feeder crew simulation inertia frequency regulation can respond to the frequency change of the system、System m88 sports bettinginertia M88 games apkreduction caused by alleviating large -scale wind power grid。But the rotor storage kinetic energy is limited，When the speed of the rotor drops to a certain limit, the wind turbine will exit the frequency adjustment and restore the speed，This will cause the system frequency to fall in a secondary fall。In the text, the inertial frequency adjustment characteristics of the dual -feeding wind power unit in different wind speed areas are analyzed，M88 games apkand quantified m88 com live casino registeranalyzed the effective release of the wind power crew in different wind speed areas to participate in the frequency adjustment process，then proposed a active speed protection control strategy based on the negative feedback of kinetic energy loss。This strategy adjusts the ratio of the speed protection controller according to the capacity of the dual -feeder unit and the real -time operating operating operating conditions -integral coefficient，M88 games apkMake the M88 Online Live Casinodual -feed power unit gradually exit the frequency adjustment process with the speed of the rotor，to maintain the stability of the wind turbine in the process of release the power，Avoid the frequency of frequency falling。Simulation results in different wind speed areas verify the effectiveness of the active speed protection control strategy。
