Simulation tool for analysis of the rotating magnetic field using spatial vector and harmonics in MATLAB

Abstract

The implementation of an application designed for the visualization and qualitative analysis of the Rotating Magnetic Field (RMF) in three-phase electrical systems subjected to power quality distortions is presented. The tool utilizes the representation of spatial vectors, and the formulation is based on the Clarke transformation, allowing for the dynamic representation of phase currents, their orthogonal components, and the trajectory of the resulting spatial vector. It simulates operational conditions such as a balanced system, open-phase faults, and the non-sinusoidal response of a six-pulse three-phase rectifier. Additionally, it facilitates the controlled injection of harmonics of orders 3rd, 5th, and 7th. The results demonstrate that the tool is consistent with vector theory and provides graphs for each distortion condition. The main contribution lies in its pedagogical and qualitative diagnostic value, enabling a direct visual correlation between distortion parameters and the geometric deformation of the RMF.
