摘要 根据双馈发电机的数学模型,对系统耦合量的处理方式进行研究,在强迫定向的定子磁场定向控制策略的基础上,针对独立运行双馈发电机系统的控制目标建立相应的励磁控制模型,并分析和比较了并网型和独立运行双馈发电机系统在构成以及控制策略上的异同。实验结果与理论分析均表明,双馈发电机独立运行时,定子输出电压以及定子磁链标准唯一取决于等效的定子磁化电流,与负载大小无关,而定子出口输出功率唯一取决于负载大小;而负载一定时,定子输出电压、定子磁链以及定子出口输出功率等都取决于等效的定子磁化电流。 From the beginning of mathematics model of doubly fed generator, how to deal with system coupling variables is researched. The corresponding excitation control model for stand-alone doubly fed generator according to control target is established based on forced stator-flux-oriented control strategy. The similarities and differences of system form and control strategy between the grid-connected and stand-alone doubly fed generator are also analysed and compared. The experiment results and theory analysis are all shown that the level of stator output voltage and stator flux for stand-alone doubly fed generator are only determined by the equivalent stator magnetising current, which are independent of load but stator port output power is only determined by load. When load is to be a certainty, stator output voltage, stator flux and stator port output power are both determined by the equivalent stator magnetising current.
