Abstract:

从能量角度出发,提出一种基于无源性控制(PBC)与自抗扰控制(ADRC)相结合的双馈感应发电机(DFIG)高性能非线性控制方法。建立了DFIG的PBC模型,并证明了其无源性,设计了电流内环PBC控制器,推导出转子电压控制量。基于ADRC原理,以由风机最大风能捕获确定的DFIG给定转速及实际转速作为输入信号,以电磁转矩给定值作为输出信号,设计了ADRC转速外环调节器。该方法在有效实现DFIG最大风能捕获同时,保证了DFIG转速、定子电流及转子电流的准确快速跟踪,实现了有功功率、无功功率独立运行;ADRC调节器能够根据系统实际情况为给定转速合理地安排过渡过程,转速、定子电流与转子电流超调量得到了显著降低,此外能够实时估计出系统所受扰动并及时进行补偿,提高了系统鲁棒性。仿真结果验证了该方法的可行性和有效性。
