摘要
在双同步速MT坐标系模型[1]的基础上,通过引入功率绕组定子磁场定向控制的思想,给出了一种适合独立电源系统的矢量控制策略,系统可以根据独立运行所带负载特性的变化调整励磁电流,实现独立电源系统的变速恒频恒压发电,并间接地实现对功率因数的调节;鉴于BDFG模型复杂,动态响应特性和鲁棒性差的特点,通过引入模糊PI调节器,改善了系统的特性;最后通过仿真验证了该控制策略的正确性和有效性。
Based on MT mode at double synchronous speed of the brushless double-fed generator(BDFG) in stand-alone power supply system, an effective vector control strategy which is based on power winding stator fieM orienting for this system is proposed. By adjusting the excitation current, this system can realize variable speed constant frequency(VSCF) and supply constant voltage and indirectly regulate the power factor. Considering the complex model, poor dynamic characteristic and robustness, and the control strategy obviously improves the performances of the system through the introduction of fuzzy-PI regulator, and the simulation results verify its correctness and effectiveness
