Abstract Based on using the node interharmonic detection of MathScript, this paper proposes a method that uses the function and controls of the LabView to realize interharmonic detection of power system. The presented method have avoided the problem effectively, whose operational time is difficult to control when outer node of MathScript is used. Not only could it also detect the ingredients of interharmonic accurately, but also the impact of results by the spectral leakage and non-synchronous sampling is small. Therefore, the method could improve accuracy of measuring result.
