近年来,风能作为一种可再生的清洁能源日益受到世界各国的广泛重视,使得近30年来风力发电在世界范围内得到了快速的发展,风力发电机作为风力发电系统的核心关键设备,其国产化设计制造问题一直是我国风力发电的瓶颈.在近十年来,随着我国风九发电设备国产化工作的开展,异步发电机的研究和设计已是电机行业要迫切解决的课题,在国家相关优惠政策的扶植和推动下,我国风电事业也得到了迅猛的发展,1998年风电总装机容量达到20．395万千瓦．随着风电规模的不断扩大,由于风能的随机性和间歇性的特点,风电对电网稳定性的影响已不容忽视.建立暂态电势为变量的风力异步发电机的数学模型,使得风力发电机在风电系统稳定性分析计算中可以类似于同步机来处理.异步风力发电机是风力发电的一种重要的机型,研究基于SPS的仿真模块的研究有很大的意义.对异步发电机而言,由于结构简单、价格便宜、且不需要严格的并网装置,可以较容易地与电网连接,但其转速可以在一定限度内变化,就能吸收瞬态阵风能量.但异步发电机需借助电网获得励磁,加重了对电网的无功功率的需求.
本文基于异步风力发电机控制系统研制的要求,按照发电机惯例建立了风力发电机的数学模型,并运用MATLAB/SIMULINK 对其过程进行了仿真,仿真结果与风力发电机实际运行情况基本相符.

In recent years,wind energy as a renewable and clean energy has increasingly come under the extensive attention of all countries in the world,making nearly 30 years of wind power in the world has been the rapid development of wind turbine wind power generation system as the core of key equipment,Localization of the design and manufacturing problems have been the bottleneck of China's wind power generation.In the past 10 years,as China's wind power generation equipment 9 of the work of domestic and asynchronous generators of research and design of the electrical industry has been pressing to resolve the issue at the national preferential policies related to the support and promotion of China's wind power Has been the cause of the rapid development of wind power in 1998 reached a total installed capacity of 203,950 kilowatts.With the wind scale of the expansion,due to the wind and the occasional random to the characteristics of wind power on the stability of power grids have been Can not be ignored.Transient potential for the establishment of variable wind generators asynchronous model,making wind turbines in wind power system stability can be analyzed in terms similar to synchronized machine to deal with them.Asynchronous wind generator of wind power is an important model,a simulation based on the SPS module of great significance.The asynchronous generators,since the structure is simple,cheap,and does not require strict and network devices,can be more easily connect with the power grid,but its speed can be changed to a certain extent,will be able to absorb wind energy transient.However,Xu Jiezhu asynchronous generator power grid was exciting,adding to the power grids of reactive power demand.
Based on asynchronous wind turbine control system developed by request,in accordance with the established practice of generating wind turbine model,and use MATLAB / SIMULINK its process of the simulation,the simulation results and the actual operation of the wind turbine basic line.
