摘　　要：本文采用了广义瞬时无功功率的谐波检测算法,控制方法分别运用了定时控制的瞬时值比较法以及SVPWM的控制方式,采用带阻感负载的可控整流桥作为谐波源,运用于三相三线制统一电能质量调节器中。仿真结果表明该方案在电网电流和电压存在畸变的情况下,能很好地跟踪谐波,并且具有很好的动态响应速度和较高的补偿效果。In this paper,a three-phase three-wire unified power quality controller based on combining harmonic detection of the generalized instantaneous reactive power with a timing control of the instantaneous value of comparative law and SVPWM control method,by using the harmonic source of a controlled bridge rectifier with resistive inductive load is presented.Through simulation,the paper verifies the following facts：While the current and voltage of power network distorts,this program can have a good tracking harmonic,and has a good dynamic response speed and higher compensation effect.
