Abstract

This paper analyzes long duration overvoltages due to backfeeding currents from the low-voltage network to the medium-voltage network through network protectors in heavily meshed underground distribution networks. Overvoltages above 3 p.u. may be developed as a result of a simultaneous occurrence of three phenomena: neutral displacement, Ferranti effect, and current chopping. A detailed model of a typical distribution network is utilized for the study. Time-domain simulations are performed using an Electromagnetic Transients Program-type program. The results demonstrate that overvoltages due to backfeeding last longer during peak load operating conditions, and the largest peak overvoltages occur at no load.
