Outil de simulation de propagation des creux de tension dans les réseaux industriels

Abstract : This dissertation deals with the voltage dip problem in industrial plants as well as the elaboration of a specific software tool dedicated to voltage dip propagation. First, the power quality aspect is introduced, focusing on voltage dip, its origin and main effects. An iterarive modelling and computational method is proposed to corputu tire load flow of a given radial networh pennitting an accurate and fast calculation. Since induction machines are widely present in the industrial plants, special attention is given to identifying the machine parameters based on minimal data provided from field measurements. Dynamic models of various orders are àaborated for the machines and compared $/ith the goal of combining simplicity with precision. The last part of the dissertation relates to the validation of the developed software tool. The developed tool is applied for a dynamic load flow calculation of a standard network with 14 machines and 3 transformers. The developed tool yields results notable for their precision, as well as for the calculation speed.
