Title: WIND TURBINE START ASSIST DEVICE
Abstract:
A wind turbine start assist device comprises: a blade rotational speed calculation unit (11) that calculates the blade rotational speed when a blade (903) of a wind turbine (900) passes through laser light output by a wind measuring lidar device (200) mounted on a wind turbine nacelle of the wind turbine; an arriving wind speed calculation unit (12) that calculates, on the basis of the wind speed in the line-of-sight direction of a laser (5a, 5b) acquired from the wind measuring lidar device (200), the speed of the arriving wind; and a start assist control unit (14) that controls, on the basis of the blade rotational speed calculated by the blade rotational speed calculation unit (11) and the speed of the arriving wind calculated by the arriving wind speed calculation unit (12), start assistance for facilitating startup of blade (903) rotation.
