Abstract

This paper is concerned with the analysis of voltage sags characteristics and propagation in radial networks following the faults in the system. Both symmetrical and asymmetrical faults are simulated at the different voltage levels and different locations in the network. Realistic pre-fault voltages and voltage phase-angles obtained from load flow study are used in all calculations. The influence of the size of the embedded generation, dynamic loads, load structure and composition on voltage sags characteristics is also investigated
