q method

Comparison of harmonic detection in three-phase four-wire system between p-q-r method and FBD method;

p-q-r法与FBD法在三相四线制系统谐波电流检测中的对比

The limitation of the p-q-r method, which is put forward by Korean research fellow Mr.

指出了韩国学者Hyosung Kim提出的p-q-r法在电力系统谐波检测中的局限性,详细讨论了在电压有畸变的情况下用p-q-r法检测三相谐波电流的问题。

The Ant-Q algorithm can effectively implement this kind of tree search,and then the optimal solution of the rectangular part optimal layout will be obtained.

使用Ant-Q算法能够有效实现这种树搜索,从而求得矩形件优化排料问题的优化解。

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.

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。
