Electrical Vehicle Impact on Distribution Network Power Quality

Published by Sampsa KUPARI, Metropolia, Helsinki University of Applied Sciences Abstract: The electrical vehicle form a huge load (and occasionally a generator as well) that is not resistive but possibly of nonlinear character. This may have an effect on distribution network power quality and possibly disturb seriously other consumers. If this is not taken careContinue reading “Electrical Vehicle Impact on Distribution Network Power Quality”

Analysis of Lightning Current Distribution in the Lightning Protection System (LPS) with using Numerical Simulations

Published by Konrad SOBOLEWSKI, Warsaw University of Technology Abstract. The paper describes the numerical model of a typical lightning protection system (LPS). This model was used to get information’s about lightning current distributions as an effect of direct lightning strike to this protection system. To perform this task was chosen software MATLAB/SIMULINK. With this toolContinue reading “Analysis of Lightning Current Distribution in the Lightning Protection System (LPS) with using Numerical Simulations”
