摘　　要：随着风力发电机装机容量在电网中所占比例不断增大,为提高电网的电能质量和保证安全、稳定、经济运行,介绍了变速恒频双馈风力发电机组的基本结构和工作原理。通过建立变速恒频双馈风力发电机在dq同步旋转坐标系下的数学模型,在Matlab/Psat软件中搭建了系统仿真模型,并对其进行了时域仿真研究。仿真结果表明:当双馈风电机组并网后,其自身参数的改变对电力系统的暂态稳定具有一定的影响。With the increase of installed capacity proportion for wind power generation in power system,to improve the power quality and ensure safe,stability and economic operation,introduces the basic structure and working principle of variable speed constant frequency（VSCF） double-fed wind generator unit.Then the dynamic mathematical model of VSCF double-fed wind gererator unit in d-q coordinate system is established.The simulation model is set up in Matlab/Past software and carries the study on time domain simulation.The results show that when double-fed wind generator units get connected,its parameters will change that has effect on power system＇s transient stability.
