| 摘要: |
| 针对分布式风力发电机，传统的扰动观察法和模糊法在风速变化频繁的实际系统中输出效率较低，不能充分发挥同步发电机的最佳性能，提出了将模糊法和扰动观察法相结合的最大功率点跟踪（ＭＰＰＴ）方法。通过和传统的扰动观察法和模糊法的比较，仿真结果表明所提方法在风速变化频繁的情况下有效地改善了系统输出特性，提高了系统输出效率。同时，利用免疫理论改进系统的动态性能。仿真结果表明所提方法减小了系统输出的振动，并提高了输出效率、响应速度和鲁棒性。 |

| Abstract: |
| An efficient MPPT（Maximum Power Point Tracking） method combining fuzzy MPPT and PO（Perturbation and Observation） is proposed to enhance its output efficiency of distributed wind power generation system. Compared with the conventional PO and the fuzzy MPPT method，the simulative results show that both the system output efficiency and performance are effectively improved when wind speed varies frequently. The immune theory is applied to enhance the dynamic performance of system and the simulative results show that the system output libration is reduced and the output efficiency，response speed and robustness are increased. |
