考虑损耗功率的双馈风力发电系统最大风能跟踪控制

摘要

对双馈风力发电系统传统功率曲线反馈控制方法作出改进，提出考虑损耗功率的最大风能跟踪控制策略。此方法通过MATLAB/Simulink建立精确的双馈风力发电机模型，并搭建考虑了铜耗、铁耗、机械损耗及杂散损耗的控制模型。经过仿真，验证了优化后控制策略的正确性。%In order to optimize the traditional power curve feedback control method, a maximum power point tracking control strategy considering loss power for doubly-fed wind energy conversion systems based on doubly-fed wind power generation was system prosed. This method built a precise model of doubly-fed wind power generator by MATLAB/Simulink and set up control model considering copper loss, iron loss, mechanical loss and stray loss. The simulation results verified the accuracy of the optimized control strategy.
