The first part of this paper presents the comparison between two models of distribution system created in computer simulation software PowerFactory (PF). Model A is an existing simplified equivalent model of the distribution system used by transmission system operator (TSO) Eltra for balanced load-flow calculation and stability studies. Model B is accurate model of the distribution system creat…
Many articles have been written about the growing harmonic problems in present day power systems. The topics range from the fundamentals of harmonics to specific case studies showing harmonic cause and effect relationships. The articles follow a common theme: they describe harmonic problems and recommend possible solutions after the problems occurs. This article describes how computer simulatio…
This paper describes the evaluation of a new harmonic calculation software. By using a combination of a pre-stored database and new interpolation techniques the software can very fast provide the harmonic data on real applications. The harmonic results obtained with this software have acceptable precision even with limited input data. The evaluation concludes here that this approach is very pra…
With the increasing proliferation of non-linear loads, more harmonics are expected to be injected into the distribution system. This paper presents time series simulations of harmonic analysis in the distribution system. Modeling and analysis approach is used to perform the time series of harmonic analysis. OpenDSS, an open-source distribution system simulator is utilized in order to perform th…
