    • PROBLEM TO BE SOLVED: To provide a wind power generating system with a start assisting function, capable of starting rotation even at a low wind speed.
      SOLUTION: When a wind speed sensor detects a wind speed of specified value or higher, a standby timer function is actuated by a timer device. When a standby timer period expires, a drive timer function with a shorter period is selected. A power generator is switched to a motor by a switching relay only during the drive timer period, for rotation for assisting start using a drive circuit. When the drive timer period expires, the standby timer period is resumed. The above processes are repeated as necessary. During this period, when the rotational speed of a rotor being monitored by a rotational speed measuring instrument based on an output voltage Vm of a three-phase energizing coil becomes a specified value or higher, power generation by a three-phase generator and charging to a battery are started.

    • 要解决的问题:为了提供具有启动辅助功能的风力发电系统,即使在低风速下也能够启动旋转。

      解决方案:当风速传感器检测到指定值或更高的风速时,定时器设备启动待机定时器功能。 当待机定时器周期到期时,选择具有较短周期的驱动定时器功能。 发电机仅在驱动定时器周期期间由开关继电器切换到电动机,用于辅助启动使用驱动电路的旋转。 当驱动器定时器周期到期时,恢复待机定时器周期。 必要时重复上述处理。 在此期间,当基于三相通电线圈的输出电压Vm的由转速测量仪器监视的转子的转速变为规定值以上时,通过三相发电机的发电并对 电池启动。 版权所有(C)2008,JPO&INPIT
