【摘要】：永磁直驱风力发电机组由于系统参数的变化而具有多变量、非线性及强耦合的特点,因此矢量控制会受到影响。文章针对永磁直驱风电系统稳定性和动态性能的问题,采用直接功率控制策略,通过省去电流闭环环节,减少了坐标变换,从而简化控制算法以改善系统性能。最后,通过Matlab/Simulink搭建直接功率控制仿真模型,对控制策略的可行性进行仿真验证;并采用DSP+FPGA实现所提出控制策略,进行了实验验证。仿真和实验结果均证明了控制策略的有效性。
[Abstract]:Permanent magnet direct drive wind turbine has the characteristics of multivariable, nonlinear and strong coupling because of the change of system parameters, so vector control will be affected. In this paper, the stability and dynamic performance of permanent magnet direct drive wind power system are discussed. The direct power control strategy is adopted, and the coordinate transformation is reduced by eliminating the current closed-loop link, which simplifies the control algorithm to improve the system performance. Finally, the simulation model of direct power control is built by Matlab/Simulink. The feasibility of the control strategy is verified by simulation, and the proposed control strategy is implemented by DSP FPGA. The simulation and experimental results show the effectiveness of the control strategy.
