摘要
考虑到测量风速困难以及风力机功率曲线难获取,提出了一种不需要知道风速及风力机功率曲线的控制方法——模糊控制在线自调整占空比控制法,介绍了风力机特性及控制策略,并详细介绍了模糊控制器的设计,并在matlab/simulink平台上搭建了相应的运行仿真系统,进行了相应的仿真分析。结果表明:在风速发生突变的情况下,也能快速地找到新的最大功率点,追踪效果显著,系统精度及效率很高而稳态误差较小,鲁棒性较好。
Considering the difficulties of measuring wind speed and getting wind turbine power-curve,a control method is introduced based on fuzzy control with automatic parameter or tuning control parameter when wind speed and wind turbine power-curve need not to be known.Introduced are some characteristics and control strategies of wind turbine and detailed design of fuzzy controller.The simulation platform is built on matlab/simulink and then a simulation system is made on the platform.The simulation results show that when the mutation occurred in wind speed,it can quickly find a new maximum power point can be quickly found with remarkable effect.And the system shows high accuracy and efficiency and better robustness.
