Abstract

This paper discusses distribution feeder related voltage recovery phenomena following typical faults in a power distribution system, considering the existence of dynamic loads. Such loads consist mainly of induction motors. A three-phase, physically based power system model is utilized, allowing inclusion of system asymmetries and imbalances, typically encountered in distribution systems. The proposed modeling and simulation is based on a quadratic power system model, which allows realistic system modeling with a minimum degree of nonlinearity, without compromising the model accuracy. Preliminary numerical experiments are presented for the purpose of quantifying the phenomena and identifying the major parameters affecting such phenomena.
