The paper proposes a novel method of current detection for an active power filter and power system, it is based on a generalized dq(k) coordinate transform. The so-called dq(k) generalized coordinate is defined as the coordinate frame rotated at the angle frequency k omega of the kth harmonic current. This method can effectively and accurately detect the fundamental current, its active and reactive components and any term harmonic current component of three-phase-circuit. The simulation results are carried out to verify the method of current detection.
