Abstract

The accurate and efficient measurement of flicker severity levels is crucial for evaluating and compensating power system flicker in electric power systems. This paper proposes a simple and fast measurement algorithm for power system flicker severity evaluation. The algorithm utilizes an equivalent measurement model and employs the Hilbert transform for effective envelope extraction. Subsequently, the extracted envelope is processed using windowed interpolation fast Fourier transform to accurately determine the flicker parameters. Finally, flicker assessment indicators are obtained. By simplifying the measurement procedure recommended by IEC Standard 61000-4-15, the proposed algorithm reduces the calculation process of flicker indicators, making it suitable for real-time flicker analysis in embedded applications. The accuracy and effectiveness of the algorithm are validated through simulation and practical test results.
