摘　　要：采用1500kW风力发电机组,基于直驱式风力发电机运行特性及最大风能跟踪原理,在Matlab/Simulink仿真环境下建立了直驱式风电系统低电压穿越的仿真模型,通过接入不同的阻抗,进而产生不同的电压跌落,对其在风电机出口发生三相短路故障时,电压跌落50%进行低电压穿越仿真,结果显示在进行电压跌落过程中风机能够保证稳定运行,验证了模型的合理性。This paper utilizes 1500kW wind turbines, based on direct drive wind generator operating characteristics and maximum wind energy tracking principle, modeling of low voltage ride through for direct-drive wind power system was built in Matlab/ Simulink software environment, and access to different impedance, producing different voltage drop, three-phase short-circuit fault occurs in wind turbine export, Simulation of low voltage ride through when the voltage drops by 50% ,The results show the system to ensure the stable operation during voltage dips process, verifies the rationality of the model.
