M-File for Calculating Harmonic Content in Current

This is an M-file implementation in MATLAB for calculating harmonic content in electrical current, delivering exceptionally high accuracy. In power systems, harmonic content in current is a critical parameter that directly impacts equipment lifespan and power quality. Accurate calculation of current harmonics is therefore essential. Using this M-file, harmonic analysis in power systems becomes more accessible while ensuring precise computational results. The implementation typically utilizes Fast Fourier Transform (FFT) algorithms to decompose current signals into fundamental and harmonic components, with configurable parameters for sampling frequency and harmonic orders. Furthermore, the customizable nature of M-files allows for adjustments and optimizations to meet specific requirements of different power system applications, such as real-time monitoring systems or power quality analyzers. The code structure includes functions for data preprocessing, windowing functions to reduce spectral leakage, and harmonic magnitude/phase extraction with proper unit conversion capabilities.
