WIND POWER GENERATION SYSTEM AND CONTROLLING METHOD OF DRIVING THE SAME

摘要

PURPOSE: A wind power generation system and a controlling method for driving the same are provided to ensure the operation time of a backup generator by minimizing the output degradation rate of a wind turbine. CONSTITUTION: A wind power generation system(1) and a controlling method for driving the same comprise a plurality of wind turbine groups(10,20,30) and a control system. A plurality of wind turbine groups comprises wind turbines(10',20',30'). The wind turbines are connected to each other and outputs power to a grid. The control system differently controls the output of the wind turbine groups. The control system successively stops the operation of the wind turbines by the turbine groups.
