ABSTRACT:
A structure of an upwind type wind turbine and the operating method thereof capable of preventing the occurrence of damage of the blades by evading excessive irregular loads from acting on the blades in the slanting direction in the event of power failure when strong wind blows, are provided.In the upwind type wind turbine having a nacelle supported for rotation on a support, the nacelle is rotated to a downwind position by rotating it by 180° from a normal upwind position and kept in stand-by condition at a downwind position when detected wind speed is higher than the predetermined cutout wind speed, which is the reference wind speed for shifting to an idle operation state. When the detected wind speed is higher than the DWSS wind speed determined based on the maximum permissible instantaneous wind speed, the nacelle is rotated from an upwind position to a downwind position and the yaw brake is released.
