| 中文摘要 |
| 风力发电机组是复杂多变量非线性系统, 具有不确定性和多干扰等特点. 目前国内应用的风力发电机组大多采用变桨变速恒频系统, 具有风能利用系数高、安全可靠、改善整机受力等优点, 然而依然面临载荷过大、功率波动大和变桨过于频繁等问题, 因此, 在大型风力发电机组系统中, 选择最适合控制策略的控制器的优化设计就显得尤为重要. 在此提出基于模糊性能评估器的控制方法, 建立非线性控制模型并设计模糊控制器, 介绍了控制器的优化设计步骤, 仿真结果表明了这种方法的有效性. |
| 英文摘要 |
| The wind turbine system is a system with nonlinear variables, uncertainties and disturbances. At present, most of the large-scale wind turbines installed in this country are of constant frequency and with adjustable speed and pitch. They are reliable with high values of utilization factor of wind power and desirable stress characteristics of the machine set. However, they are undergoing overloading, variation in power and frequent changes of pitch. To deal with these problems, a new control method is proposed in this paper based on the fuzzy performance evaluator. In this method, a nonlinear control model is built; a fuzzy controller is designed with details described. Simulation shows the effectiveness of the proposed method |
