| 为了缩短爬山算法的计算周期, 提高直驱永磁风力发电系统最大风能捕捉的响应速度, 提出一种根据功率扰动寻求最大功率的优化爬山算法. 该算法在变步长爬山算法盲目搜索的基础上添加数据存储输出功能, 构造了与电机转速对应的最大输出功率表, 避免重复的计算, 同时结合功率反馈控制来实现系统最大功率追踪. 运用MATLAB对该算法进行仿真验证, 结果表明本文所述算法的响应速度和稳定性明显超过传统变步长爬山算法. |
| 英文摘要 |
| An optimized hill-climb search based on power-perturbation is brought forward for the direct-drive permanent-magnet wind-power generation(D-PMSG). This algorithm reduces the algorithm period and increases the speed in capturing the maximum wind power. By adding the function of data-store-access to the variable-step hill-climb search(HCS), we make this algorithm capable of generating the updated Max-Power work-table according to the motor speed for avoiding the repetitive calculations. Meanwhile, it realizes the tracking of the maximum wind power by integrating the power feedback control. Simulation results on MATLAB show that the proposed algorithm outperforms the traditional variable-step HCS in response speed and stability. |
