Inter-Harmonics Analysis Based on the STFT Applied to the Power System

Abstract:

This paper introduces a method of analyzing the time-frequency characteristics for inter-harmonics by Short Time Fourier Transform (STFT). Compared with the traditional arithmetic, the STFT can acquire more precise results and provides theoretical base for inter-harmonic detection. The STFT is used to analyze the inter-harmonics by selecting proper window slides function in Matlab which can acquire more precise resolution for the time-frequency characteristics. This method is useful to eliminate the inter-harmonics in power system. So the quality of power energy can be further improved.
