摘　　要：以同步和异步风力发电机为研究对象,分析其在恒速恒频和变速恒频发电方式下,并入配电网后对电网相关参数的影响。通过对风力发电机的研究,建立了风速、风力涡轮机和传动机构的数学模型[1,2],并用Matlab/Simulink搭建风力发电机模型和电网模型。在输入风速发生变化过程中,仿真并观测发电机的输入机械转矩、转速、机端电压和电流,以及发电机输出有功和无功的变化情况。对不同发电方式下的结果作了简单分析,为进一步研究并网和控制技术提供依据。This paper studies synchronous and asynchronous generator under Constant Speed Constant Frequency（CSCF） and Variable Speed Constant Frequency（VSCF） generation technologies and analyzes the impact of relevant parameters on the power grid when it is connected to the distribution network. Through the research on the wind generator, the model of wind speed, wind turbine and drive gear is established and then wind generator model and power grid model are built based on MATLAB/Simulink. When the wind is in the process of changes, this paper simulates and observes the changes of the generator＇s input mechanical torque, rotor speed, stator voltage and current, output active power and reactive power. The results of different generation technologies are analyzed which provides the basis for the further study of parallel-in and control technology.
