    • 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 DEG from 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 said 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.
    • 提供了一种逆风式风力涡轮机的结构及其操作方法,其能够通过在强风吹动时发生断电时通过避免过大的不规则负载在倾斜方向上作用于叶片而防止叶片的损坏。 。 在具有支撑在支撑件上旋转的机舱的逆风式风力涡轮机中,通过从正常的逆风位置旋转180°将机舱旋转到下风向位置,并且在顺风位置处保持待机状态 检测风速高于作为转入怠速运转状态的基准风速的预定切断风速。 当所述检测到的风速高于基于最大允许瞬时风速确定的DWSS风速时,所述机舱从上风位置向下风向位置旋转,并且所述偏航制动器被释放。
