Time series simulation of the impact of harmonics using measured harmonic data

One of the major power quality concerns is harmonic distortion that is caused by the non-linearity of customer loads. Hence, harmonic studies have become an important part in power system modeling, simulation and analysis. This paper presents an application of an Open-source Distribution System Simulator (OpenDSS) for harmonic analysis in time series. Two test case studies, with and without har…

Harmonic domain modeling of a distribution system using the DIg SILENT power …

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…

Evaluation method for harmonic distortion and power losses of photovoltaic sy…

The use of photovoltaic power generation systems is increasing all around the world. However, photovoltaic systems use inverters and other electronics to convert and control DC power from panels to AC power. This may lead to increased power losses, decreased efficiency and power factor, overheating due to higher parasitic currents, and possible damages of the devices designed to work with smoot…

Software predicts harmonic problem and simulates alternative solution

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…
