摘　　要：飞轮作为一种储能装置,具有较大的储能容量,并能将所存储的动能转换为电能,反之,亦能将电能转换为动能。开发了基于DSP微处理器的飞轮控制算法,包括飞轮的启动控制和充放电控制,启动控制算法中实现了对飞轮转速的自动检测,充放电控制实现了功率反馈PI控制。感应电机采用VVVF控制,电机驱动逆变器采用空间矢量调制PWM控制。实验结果表明,飞轮具有较快的响应速度,达到100ms,并具有很好的充放电特性。Uninterrupted Power Supply( UPS ), electrical vehicle and distributed energy generator etc.need power storage system.Flywheel applied as a energy storage device has large capacity and can transfer the dynamic to electricity,or conversely the electricity to dynamic. The authors developed a control algorithm for flywheel droved by inductance mo-tor based on DSP, including flywheel start-up control, charge and discharge control. The automatic detection of rotating speed is done before flywheel start-up. Charge and discharge controls were implemented by power PI feedback control.VVVF method was used to control the inductance motor. Using space vector PWM , the inverter for driving the inductance motor was controlled. The experimental results shown that the fast flywheel response is about 100 ms, and the preferable behaviors of charge and discharge are achieved.
