Article
Full-text available
Accurate electrical parameters of the overhead power lines are essential inputs for industry (protection relays settings, power flow calculations, grid stability estimation) and scientific studies (simulation models in general). While impedance measurements of overhead power lines are common today, capacitance measurements are mostly insufficiently...

In recent years, the emerging fear of an energy crisis in central Europe has caused an increased demand for distributed energy resources (DER), especially small photovoltaic rooftop installations up to 10 kWp. From a technical point of view, distributed PV in low-voltage networks is associated with the risk of power quality violation, overvoltage,...

This paper studies the voltage stability of the Slovak Republic’s power system (PS) based on an assessment of the PV curves. The PV curve is a tool for assessing voltage stability, and based on its shape, it is possible to determine weak and strong voltage nodes with the possibility of voltage stability reserve quantification. We present an analysi...
Conference Paper
The paper discusses the ongoing trends in distribution systems, such as increasing distributed energy generation combined with small battery storage systems. Distributed energy generation alone has a negative effect on power quality and can cause an increase in power losses in a situation with no consumption at a close distance. However, the situat...
Conference Paper
Distributed energy resources have become a stable and rapidly growing part of power systems. DER character and properties depend significantly on the type used technology and application. Their common feature is the probabilistic nature of their behavior and parameters. Penetration of DER into classical power systems raises the question of power qu...
Conference Paper
As is electromobility is still expanding, its effects on the power grid need to be expected and be prepared for. This paper is analyzing the possibilities of creating a very simple probabilistic model while keeping the outputs still accurate enough for most of the applications in power engineering. The simplicity and flexibility of this model are p...
Article
Full-text available
Calculation and measurement of the overhead power lines electrical parameters is common practice in today’s electrical engineering industry; however, there is very little data to actually compare these two approaches because measured data in such detail are mostly unavailable for academic purposes. Based on the very detailed model of an overhead po...
Article
Full-text available
The problem of electromagnetic fields produced by overhead power lines is still a widely discussed topic. These concerns itself are coming not only from the power line designers, but also from general public sector. Therefore, the topic can be separated into two different areas of interest: health concerns and technical problems. Conducted discussi...
Article
Full-text available
The current transformation of power systems is aiming towards distributed source integration and general decentralization. Renewable energy sources and support of local energy supply create conditions for widespread use of new technologies and smart grids. As the electrical grids become more electrically independent, the importance of frequency con...
Article
The separation distance is defined as distance providing the electrical insulation between the lightning protection system and metallic installation components of a building. This paper presents experimental verification of material coefficient which defines separation distance for external lightning protection system. Separation distances for diff...
Article
Full-text available
This paper is aimed on the calculation of the electrical parameters of the overhead transmission lines. Standard trans- position and untransposed calculations are presented, also with results on the existing power line on 110 kV voltage level and known measured values of the electrical parameters. These measured parameters are used as the reference...
Article
Full-text available
p> This article presents a superposition method in combination with the Coulomb’s law and the Method of image charges for calculation of the electric field distribution generated by high voltage overhead power lines above a flat surface in every dimension. Such calculations are required to ensure the operational safety of people exposed to the acti...
Conference Paper
The paper presents a finite element method for numerical calculation of magnetic flux density around a high voltage power transmission line. The need of such calculation is based on growing safety demands of people exposed to the action of external magnetic field as well as reduce the cost of people protection. Method extends the calculation of mag...
