| 摘 要： | 研制了一种智能的光伏发电逆变器,它既可以与电网并网又可以独立运行.当它与大电网并网时,采用电压电流双闭环的控制策略,以电流源的形式输出电能;当大电网断开出现孤岛时,它采用电压有效值外环瞬时值内环的闭环控制并进行模糊自调整PI参数,以电压源的形式输出电能.最后在光伏发电实验平台上验证了该方法的有效性.

| Abstract: | A novel smart PV power inverter is developed.It runs not only in connected-grid but also in disconnected-grid and keeps voltage stable rapidly in the transient process.When the inverter connected with the grid,the inverter produces power as a current-source with a voltage-current close loop control strategy.Once the islanding event took place,it runs as a voltage-source,adopting a voltage virtual value outer-loop and voltage instantaneous value inner-loop control strategy and fuzzy self-adjusting for PI parameters.Finally the experimental results demonstrate the effectiveness with the PV experimental platform. |
