基于半物理仿真平台的风力机PID控制研究

摘要

The control method of taking accounting of mechanical transmission and damping is researched on the basis of the characteristics of variable speed variable pitch wind turbines,the wind turbine semi-physical simulation platform,and the es-tablished model of wind speed and different operating regions of wind turbines. The experiment verification of the method was conducted. The results showed that the experiment of real physical platform can reflect the mechanical properties of the wind tur-bines better,and the established PID control method is relatively close to the control characteristics of real wind turbines.%针对变速变桨风力机组的特点，基于风力机半物理仿真平台，根据建立的组合风速模型及风力机不同的运行区域，研究了考虑机械传递、阻尼等因素的风力机PID控制方法，并进行了实验验证。结果表明，真实物理平台实验更能体现风力机的机械特性，建立的PID控制方法也较为贴近真实风机的控制特性。
