چکیده
Prior to installation of a large harmonic load it is necessary to conduct a harmonic analysis using computer simulation in order to pr"iirt possible negative effects of harmonics' The 'problem is that many parameters are unknown and need to be assumed. One of these are existing or background harmonic levels. Tthe paper describes the resubs of harmonic measurements as Qn inclication of existing harmonic levels' A calculation for the connection of a high power convefter-fed induction furnace to a MV system is presented cLs an example. The results indicated the specific needs for data collection, especially load data and the requirement. Furthermore it is pointed out, that caiculation give only a tent(ttive hint on the harmonic propagation, but measurement is an indispensable part for the analysis of harmonic propagatiott in power sYstems.

A Critical Assessment of the Performance of Magnetic and Electronic Indices of Aromaticity
The lack of reference aromatic systems in the realm of inorganic aromatic compounds makes the evaluation of aromaticity in all-metal and semimetal clusters a difficult task. To date, calculation of nucleus-independent chemical shifts (NICS) has been the most widely used method to discuss aromaticity in these systems. In the first part of this work, we briefly review our previous studies, showin...
متن کاملLocal aromaticity of the six-membered rings in pyracylene. A difficult case for the NICS indicator of aromaticity.
In this work, we have analyzed the local aromaticity of the six-membered rings (6-MRs) of planar and pyramidalized pyracylene species through the structurally based harmonic oscillator model of aromaticity (HOMA), the electronically based para-delocalization index (PDI), and the magnetic-based nucleus independent chemical shift (NICS) measurements, as well as with maps of ring current density. ...
متن کاملMethod/basis set dependence of NICS values among metallic nano-clusters and hydrocarbons.
The influence of various all-electron basis sets and effective core potentials employed along with several DFT functionals (B3LYP, B3PW91, BLYP, BP86 and M06) on the magnitude of nucleus independent chemical shift (NICS) values in different metallic nano-clusters and hydrocarbons is studied. In general, it is demonstrated that the NICS values are very sensitive to the applied method/basis set; ...
متن کاملRole of electron density and magnetic couplings on the nucleus-independent chemical shift (NICS) profiles of [2.2]paracyclophane and related species.
The nucleus-independent chemical shifts (NICS) and electron density profiles along the inner and outer regions defined by the two stacked aromatic rings of [2.2]paracyclophane have been analyzed and compared to those of free benzene and p-xylene and benzene dimers taken as reference models. It is found that stacked aromatic rings show a reduction of the NICS indicator of aromaticity as compared...
متن کاملInvestigating the Effect of Network Parameters on Coordinated Cyber Attacks against a Simulated Power Plant
The fact that modern Networked Industrial Control Systems (NICS) depend on Information and Communication Technologies (ICT), is well known. Although many studies have focused on the security of these systems, today we still lack the proper understanding of the effects that cyber attacks have on NICS. In this paper we use our previously developed framework to study the effects of network paramet...
