| Abstract: | Appling Hilbert space to definite orthogonality, this paper presents a new method of detecting harmonic and reactive currents. The algorithm of this method is simple and can be realized easily. This method can precisely detect fundamental reactive current or harmonic currents instantaneously. The validity of the proposed approach has been proved by the simulation results. |
