基于定子磁链定向的双馈电机变流器控制策略

风能是一种蕴藏量大、分布广、可再生且无污染的重要能源,为了更好更方便地利用风能,在不具备风电场进行实验的情况下,可以建立一个能模拟风电场特性的实验平台。在构建10kW变速恒频双馈电机实验平台的基础上,采用DSP2808芯片编写了变流器的基于定子磁链定向控制策略的机侧和网侧的程序,并通过空载并网实验验证了本设计的可行性。

Doubly-fed motor inverter control strategies based on stator flux

Wind power was a kind of reserved,widely distributed,renewable and pollution-free energy,and had been paid attention by the countries all over the world.In order to use the energy more convenient,an experimental platform was established under the situation that there was no wind farms for experimentation.Based on the experiment platform of the 10 kW variable speed constant frequency doubly-fed machine (DFIG),the program of machine side and network side of converter based on stator flux oriented control strategy was written by using DSP2808 chip.And the feasibility of this design through the light parallel in the experiments was verified.
