摘要
通过理论推导得出,无论电压有无畸变,基于Fryze功率理论的谐波检测算法与基于瞬时无功功率理论的p-q算法最后检测出的有功电流是完全一致的。当电压无畸变时,两种方法都可以精确检测三相系统的谐波及无功电流,但在Fryze功率理论方法中没有坐标变换,计算量要比p-q算法少很多。
Through theoretical derivation, we conclude that the active current detected by Fryze theory and by p-q theory is completely the same no matter whether voltage is distorted or not. When voltage is not distorted, these two methods can detect harmonic and reactive current. And In Fryze method there＇s no coordinate conversion, the amount of calculation is much fewer than p-q theory.
