A wind power generation system has a windmill, a lift improvement device, a power generator, a storage, and a controller. The windmill rotates when receiving an airflow. The lift improvement device has a capability of operating and halting, the lift improvement device increases a lift force to a blade of the windmill when operating. The power generator generates power by rotation of the windmill and a torque is generated in a direction suppressing rotation of the windmill. The storage stores a plurality of characteristic maps indicating characteristics of the torques of the power generator in relation to rotation speeds of the power generator. The controller controls a power generation amount of the power generator by switching and using the plurality of characteristic maps of the storage in correspondence with a state of operating or halting of the lift improvement device.
