This paper proposes a new inter-harmonic detecting algorithm based on the generalized dk-qk rotational coordinate transform theory. The proposed algorithm can be used to detect the inter-harmonics of any balanced three-phase system. Firstly, the detected inter-harmonic frequency is transformed to integer; Then the integral harmonic is obtained by applying the dqk coordinate transform; Finally, the inter-harmonic result is restored by the inverse frequency transform. In addition, the zero-sequence component can be detected by the similar algorithm. The simulation and experimental results prove that the proposed method is valid for detecting any terms of inter-harmonic.
