| 中文摘要:基于风力机的发电效率因环境风速变化而改变，本文选用LabVIEW为仿真平台建立风力机最大功率点的追踪系统。首先根据风力机的风能捕获输出功率公式，在LabVIEW平台上搭建了风力机系统模块、风力机控制模块、风轮转速调节模块、风速变化判断模块等。为了弥补传统扰动法存在的追踪精度等问题，利用变步长的扰动观测法对输出功率进行最大功率点追踪，使风力机的输出功率保持在最大输出功率。实验结果表明该系统在不同的仿真风速环境下，能有效的追踪风力机最大输出功率点。 |

| Abstract:Based on the wind turbine power efficiency changes due to wind speed of environment, the wind turbine maximum power point tracking system is established in this paper using LabVIEW as simulation platform .Firstly, according to the wind energy capture and output power formula, the wind turbine system module, the wind turbine control module, the wind turbine speed regulation module, the wind speed change judgment module are designed on the LabVIEW platform. In order to remedy tracking accuracy of the traditional perturbation method, the perturbation observation method with variable step size is adopted for maintaining at the maximum output power of the wind turbine. The experimental results show that the system can track the maximum output power of the wind turbine effectively at different simulated speed. |
