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…

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…

Harmonics calculation software for industrial applications with adjustable sp…

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…

Harmonic suppression and simulation based on matlab

An active power filter (APF)based on digital signal processor (DSP) and complicated programming logic component (CPLD) is designed in this paper. Solft and hard wares are introduced and the simulation experiment to compensate the reactive power and harmonics in three-phase four-wires system is done. By using Matlab. simulation model is build for the device. The result shows that this model can …

Modeling and simulation of 6-Pulse rectifier drives with impacts to input cur…

This paper describes the measurements and simulations of harmonics from six pulse adjustable speed drives in Pulp and paper Industry. Harmonic analysis of the distribution system is essential to study the behavior of equipments connected in the non-sinusoidal system environment for designing and optimal location of filters. The simulations are done in Mat lab by sim-link circuit simulator. Vali…

Harmonic modeling and simulation requirements for the revised IEEE standard 5…

Abstract: As IEEE Standard 519-1992 enters its final revision stages for a new release, it is becoming clear that new and improved modeling and simulation techniques are required to address various technologies and control systems that were not considered in the 1992 version. Probably the single largest issue is the emergence of "active rectifier" AC-DC converters. However, other modeling and …

Test systems for harmonics modeling and simulation

This paper presents three harmonic simulation test systems. The purpose is to demonstrate guidelines for the preparation and analysis of harmonic problems through case studies and simulation examples. The systems can also be used as benchmark systems for the development of new harmonic simulation methods and for the evaluation of existing harmonic analysis software.

Software for the evaluation of winding factor harmonic distribution in high e…

In this paper a software developed for the determination of winding connections, the calculation of winding factors and the evaluation of their harmonic distribution of three and two phase windings is presented by using as input data simply the number of slots, pole pairs and phases. The software is implemented as a function in MATLAB environment. By means of some examples, covering the most re…
