摘要
传统的双馈电机数学模型是忽略铁耗的,因此在实现最大风能追踪时忽略了铁耗的影响,造成了理论值与实际值的偏差,本文将建立含铁耗的双馈电机(DFIG)数学模型,并建立模糊规则,利用模糊控制器实现双馈电机的最大风能输入和最高电能反馈电网的最优控制策略。并通过Matlab仿真和实验,验证了本文提出的最优控制策略的正确性。通过模糊控制,实现了系统响应速度更快、控制策略更简单,而且系统在风速变化下也具有良好的动态调节性。
The ordinary control strategy on the DFIG ignores the iron loss. This paper will build the DFIG mathematical model considering the iron loss and build the fuzzy control rule to realize the optimal control strategy. The correctness and good dynamic adjusting of this optimal control strategy are proved by experiment Matlab/Simulink. And the responding time of the system has been reduced by using the fuzzy controller.
