Software tool for the analysis of electromagnetic disturbances propagation

Abstract. The analysis of the conducted electromagnetic disturbances propagation is a complex issue, involving detection and analysis of electromagnetic disturbances, modelling of power grids ’ elements, and study of the influence on the grids ’ elements (electric lines and power transformers) of the existing disturbances. The paper presents a software tool for analyzing the propagation of electromagnetic disturbances. It was implemented as a virtual instrument developed in the graphic programming environment LabVIEW, and helps for the study of propagation of harmonic and unbalanced current/voltages, over-currents and voltage dips caused by common faults in radial distribution power grids.
