| Abstract: | In this paper, a new independent component analysis approach to remove power frequency disturbance （ICA） is proposed, which can remove the power mixed vibration signals effectively. A brief introduction about the theory of ICA is from vibration signals based on frequency disturbance from the also presented. The validity of the proposed approach is verified by a simulation and test resuhs. |
