摘要
对直驱式风力发电系统中交错并联控制器的研究和控制进行了较为深入的分析,得出了单Boost电路下的小信号模型下的传递函数,并据此设计了PI参数。对并联的Boost电路的均流控制和控制时的电流采样时间进行分析。对此,在3.5 kVA的并网逆变器上进行了实验验证,实验结果验证了设计的正确性和价值。
The research and control of parallel interleaving boost converters in direct-driven wind power generation system were given, obtaining the transfer function under small-signal model. PI parameters can be designed according to the stuty. The current sharing control of parallel interleaving boost converter and choice of sample time were analyzed. At last, the theory was verified on a 3.5kVA grid-connected inverter. And experiment results proved the design.
