摘要
对直驱型风电机组交错并联斩波器的控制和设计中的关键问题进行了较为深入的分析,得出了基于最大功率跟踪(MPPT)算法的斩波器输入电流指令解析表达式;给出了N重交错并联升压斩波器纹波电流的统一表达式,并基于此得到了滤波电感的设计准则;对1.2MW直驱型风力发电全功率并网变流机组进行了全面的仿真,仿真结果验证了提出的控制和设计方案的正确性,具有一定的实用价值。
The key problems during the design and control of parallel interleaving boost chopper in directly-drive wind power generation system were analyzed. The analytic expression of input current order based on MPPT algorithm was obtained, the uniform expression of ripples current in N parallel interleaving boost chopper was given, and the design criterion of the filter inductance was derived. The simulation analysis of 1.2MW directly-drive wind power generation power interconnected converting unit was made, the results show the utility and the trueness of the proposed control and design scheme.
