摘　　要：异步风力机因风速变化的不规律会导致电网电压崩溃。UPFC是FACTS元件中装置中功能最强大的元件,可以维持风电场电压和系统稳定。运用UPFC、风力机和异步发电机的数学模型,在Matlab/Simulink中建立了带UPFC的风电场仿真模型,通过研究风速骤变时带与不带UPFC的风电场功率、电压状况,验证了UPFC对风电场电压的支持作用,并能维持风电场及系统的稳定,保证风力发电机的持续运行。Voltage of asynchronous wind generator may collapse because of irregular changing of wind speed.UPFC is the most useful component in FACTS devices.It can maintain voltage of wind farm and system stability.Using the mathematical models of UPFC,wind turbine and asynchronous generator can model the wind farm with UPFC simulation models on Matlab/Simulink simulation platform.Studying the power and voltage of wind farm with/without UPFC when irregular changing of wind speed verifies that UPFC can support the voltage of wind farm,maintain system stability and make wind farm operate continuously.
