    • Wind power can be always detected even when a wind turbine 11 forcibly brakes, as well as cost of components can be reduced. A generator includes a wind turbine 11 rotated by wind power to generate a driving force, a dynamo 19 operated by the driving force of the wind turbine 11 to generate electricity, a short-circuit brake 21 for switching the output side of the dynamo 19 between an output state and a short-circuit state, a rotational speed input unit 41 or an arithmetic processing part 51 for recognizing the magnitude of the wind power in both of the output and short-circuit states based on the rotational speeds of the wind turbine 11 in both of the output and short-circuit states, and an arithmetic processing part 51 for determining which state the dynamo 19 should be changed over to between the output and short-circuit states based on the rotational speed of the wind turbine 11 and controlling the switching of the short-circuit brake 21 based on the determination result.
    • 即使当风力涡轮机11强制制动时也可始终检测风力,并且可降低部件的成本。 发电机包括由风力旋转以产生驱动力的风力涡轮机11,由风力涡轮机11的驱动力操作的发电机19以发电,短路制动器21用于将发电机19的输出侧切换 输出状态和短路状态;转速输入单元41或算术处理部分51,用于基于风力涡轮机11的转速识别输出和短路状态两者中的风力的大小 在输出和短路状态两者中,以及运算处理部分51,用于基于风力涡轮机11的转速确定发电机19应该切换到输出状态和短路状态之间的哪个状态,并且控制 基于确定结果切换短路制动器21。
