| 摘 要： | 为了在电网电压骤降情况下满足电网对风力发电系统的要求,对无刷双馈电机(BDFG)风力发电系统矢量控制进行了研究,给出了计及电网电压变化时BDFG的控制模型及基于模糊规则参数自整定PI调节器的改进控制策略,并进行了仿真研究.仿真结果表明,该控制方案可以较好地控制BDFG控制绕组电流,降低电磁转矩波动,提高BDFG风力发电系统在电网电压骤降情况下的不间断运行能力.

| Abstract: | Vector control of wind power generation system with brushless doubly-fed generator(BDFG) was studied to meet the needs of grid on wind power generation systems under voltage sag.The revised control model of BDFG considering variations of grid voltage and the improved control scheme based on a parameter auto-tuning PI controller with fuzzy rules were proposed.Simulation results show that the proposed schemes are able to regulate the control winding current of BDFG,to reduce its electromagnet torque fluctuati... |
