| 摘 要： | 介绍了一种基于改进型谐波检测方法.该改进型检测方法用积分、延时和增益环节代替传统ip、iq检测方式中的低通滤波器,检测延时可减少到1/6个电源周期,同时这种方法可以推广到单相、三相四线电路和三相不平衡负载的场合中.仿真结果验证了该控制方案的正确性.

| Abstract: | Improved harmonics detecting method is introduced.This improved detecting method replaces the low pass filter in conventional ip,iq method by integration,delay and gain,which can reduce the detecting delay to 1/ 6 of source period.Meanwhile,this method can be applied to a single phase circuit,three phase four wire circuit and three unbalanced loads.Simulation results prove the validity of the control method. |
