| 摘 要： | 讨论了1.2MW变速恒频风力发电变流系统中的多重斩波器。变流系统采用AC/DC/AC结构,基于DSP控制,使得永磁同步电机输出的电能高效地传递到电网。其中多重斩波器采用平均电流法控制,利用状态空间平均法以及小信号模型分析了升压斩波电路,确定了电路的PI调节器参数。实验结果验证了理论分析,证明PI调节器具有很好的动态性能和稳态性能。

| Abstract: | This paper presents the wind energy conversion system with a rated output of 1.2MW which is applied to the variable speed constant frequency wind energy system(VSCF).It utilizes the AC/DC/AC power converter to deliver the high-level power energy from permanent-magnet generators to the grid.As the important section of DC energy delivering link in the system,a multiple Boost converter controlled by DSP with average current-control strategy is proposed and specifically analyzed in this paper.By using the state space averaging method and small signal modeling,the parameter of PI regulator is specified.The experimental results verified the feasibility of the multiple Boost converter used in the wind energy conversion system and confirmed the analysis. |
