摘要
提出了采用电流型脉冲整流器实现的风能或太阳能发电并网的新方法 ,对电流型脉冲整流器的逆变特性和直流至交流具有的升压特性进行了分析研究 ,该方案很好地解决了采用电压型脉冲整流器并网发电 ,在风速低于同步转速时无法将同步发电机所发出的电能充分回收的问题。控制系统采用了DSP控制芯片 (TMS32 0C2 4 0 )。实验证明 。
A novel method based on current source PWM rectifier to realize clean energy generation to utility grids have been put forward.The current PWM rectifier gives an advantage over voltage source PWM rectifier.It can boost the voltage from DC side to AC side.The energy conversion system proposed have solved the energy utilization problem successfully at low wind speed and insufficientsun light.The experimental results show that with the new scheme the electric energy from wind or sun can be utilized even if when wind speed is lower and the sun light is not enough strong..
