摘要
建立了包括异步感应式发电机、双馈感应式发电机和永磁同步发电机在内的3种不同的风电机组数学模型,针对不同的机组类型提出了相应的风力机模型和变频器控制策略。以建立的数学模型为基础确立了接入无穷大系统的风电场模型。模拟风力机风速变化情况,对各个风机模型在风速扰动下的响应特性进行了仿真分析研究,并将仿真波形进行了简单的比较。结果验证了所建模型的正确性,并且表明变速恒频发电机组与异步发电机比较而言具有更好的动态特性。
Three different dynamic models for wind turbine sets, including asynchronous machine, doubly-fed machine and permanent-magnet synchronous machine are established. According to their different kinds, the paper also presents the different models of wind-turbine as well as different control algorithms to rectifier. It constructs a model of wind farm which connected with infinite system on the basis of above dynamic models, too. Taking changing wind speed for example, the response characteristics of different dynamic models for wind turbines are simulated and simply compared. The simulation results show that the established model are correct and variable speed wind turbines（VSWT） possesses better dynamic characteristics.
