The definition of input parameters for modelling of energetic subsystems
(EDP Sciences, 2013-06-26)This paper is a short review and a basic description of mathematical models of renewable energy sources which present individual investigated subsystems of a system created in Matlab/Simulink. It solves the physical and ... -
Evaluation of Harmonics Impact on Digital Relays
(MDPI, 2018-04-11)This paper presents the concept of the impact of harmonic distortion on a digital protection relay. The aim is to verify and determine the reasons of a mal-trip or failure to trip the protection relays; the suggested ... -
New experimental research stand SVICKA neutron field analysis using neutron activation detector technique
(EDP Sciences - France, 2018-04-18)Knowledge of neutron energy spectra is very important because neutrons with various energies have a different material impact or a biological tissue impact. This paper presents basic results of the neutron flux distribution ... -
Two-Terminal Algorithm Analysis for Unsymmetrical Fault Location on 110 kV Lines
(MDPI, 2019-03-27)This work analyses a two-terminal algorithm designed to locate unsymmetrical faults on 110 kV power transmission lines. The algorithm processes synchronized voltage and current data obtained from both ends of the protected ... -
Analysis of IEC 61850-9-2LE Measured Values Using a Neural Network
(MDPI, 2019-04-28)Process bus communication has an important role to digitalize substations. The IEC 61850-9-2 standard specifies the requirements to transmit digital data over Ethernet networks. The paper analyses the impact of IEC 61850-9-2LE ... -
A Physical Calibrator for Partial Discharge Meters
(MDPI, 2019-05-29)This article offers an alternative method of calibrating partial discharge meters for research and teaching purposes. Most current modern calibrators are implemented as precise voltage pulse sources with a coupling capacitor. ... -
On Minimisation of Earthing System Touch Voltages
(MDPI, 2019-10-11)Finding cost efficient earthing system design with acceptable level of safety might be quite tedious work. Thus, many earthing system engineers try to find the most suitable design either by employing only their best ... -
Analysis of Dense-Mesh Distribution Network Operation Using Long-Term Monitoring Data
(MDPI, 2019-11-14)The technical and economic aspects and the possibility of the mesh network topology offering many radial configurations lead to the fact that large municipal networks are generally under radial operation. However, it is ...
