风场与风力机模拟系统的设计与实现

为了满足变速恒频风力发电技术的研究需要,提出了一种基于谱密度分析的自回归风速模型;并结合基于叶片微元受力分析的风力机转矩计算模型,设计了一套风场与风力机模拟系统。试验证明,该系统能够根据外部设定,结合主控制器指令,真实地模拟风力机在不同风况下的实际运行状态,同时驱动直流电机输出风力机模拟风轮转矩。该系统的实现,为实验室条件下研究风力机的运行提供了一套完整的解决方案,为风力发电技术的试验开发做出了现实铺垫。

Design and Actualization of Wind Farm and Wind Turbine Imitation System

In order to meet the requirements of wind power generation research,the wind and wind turbine imitation system is designed,in which an Auto-Reverse wind model using spectrum analysis is created and a wind turbine torque calculating model is built based on mechanical analysis.In experiment,receiving orders from main controller,this system could imitate wind turbine running status by user requests and drive DC machine to output the responding turbine torque.The foundation of this system has provided a completed method for researching the running of wind turbine in experimental circumstance,and offered a practical help for wind power generation development.
