| Abstract: | An improved detection algorithm of reactive current is proposed in this paper.This improved algorithm can detect the reactive current precisely by detecting the phase value of fundamental voltage of the power grid. The theoretical analysis and MATLAB simulation indicate that the reactive current of system can be detected accurately by the improved detection algorithm when the three phase voltage is unbalance and non-sinusoidal. |
