European Lightning Detection Workshop (ELDW) 2017

The European Lightning Detection Workshop (ELDW) held place from 17 to 20 October in Belgrade with the support of the Mihajlo Pupin Institute. We have been selling the SCALAR system services on the Serbian market in collaboration with the Mihajlo Pupin Institute for 2 years. We also cooperate with the Serbian transmission operator, EMS Serbia.

At the workshop, our associates presented the following papers: "Livestock protection against lightning strike” (Vladimir Djurica”, "Usage of LLS Data for Operation, Design and Protection of Electric Power Networks" (Miha Bečan), "Use of the SCALAR system lightning data for rehabilitation of the earthing of the power line towers" (Primož Hrobat), and "Implementation of SCALAR services in TSO EMS" (Goran Milev).

The EUCLID association meeting was also organised within the scope of the work programme. We have been a member of this association since 2000 when it was founded. Today, the EUCLID combines lightning localisation system operators from more than 20 European countries. Therefore, the location of this year's workshop is not coincidental, because we wanted to present the EUCLID association to our consumers in Serbia.

It should also be emphasised that our associate, Mr Goran Milev, was elected as President of the EUCLID association for a three-year term of office.

The sixth energy literacy promotion festival for the youth (Elektrofest)

Ljubljana, 15 September 2017 - For the sixth year in a row, ELES, Gen energija, Milan Vidmar Electric Power Research Institute and the Faculty of Electrical Engineering of the University of Ljubljana joined forces. They presented the functioning of the electric power system to young people. 

The Milan Vidmar Electric Power Research Institute, ELES, Gen energija and the Faculty of Electrical Engineering of the University of Ljubljana prepared four electric stations or expert sets of content in the field of electric power for more than 400 students. The experts from ELES prepared a lecture, where they used interesting and interactive ways to present the Slovenian electric power system and the role of ELES in it. The employees of the Milan Vidmar Electric Power Research Institute took students to their high voltage laboratory, where they have been implementing tests on devices that operate in the electric power system for more than fifty years. They presented the system for automatic localisation of atmospheric discharge Scalar and simulated the lightning effect. GEN energija company presented a simulation of the operations of the Krško Nuclear Power Plant, at the Faculty of Electrical Engineering, students used games to learn about the principles of electric power transmission from power plants to users. Zavod 404 institute presented three projects of students in front of the ELES business office – i.e. the arcade console (device for playing computer games), growbox and hovercraft. 

Within the scope of the event, an official opening of the event also took place at ELES, where the participants were addressed by the director of the IT and Telecommunications Division in ELES, Mag. Venčeslav Perko, the Head of the Electric Power System Control and Operation Department at EIMV, Mag. Andrej Souvent, and the Dean of the Faculty of Electrical Engineering at the University of Ljubljana, Prof. Dr. Gregor Dolinar.

  The participants were initially greeted by Mag. Venčeslav Perko, the director of the IT and Telecommunications Division in ELES, who emphasised that ELES is well aware of the significance of strengthening energy literacy among the youth. "Knowledge and understanding about energy and the energy sector are an important basis for responsible designing of our energy future," said Mag. Venčeslav Perko. 

The Head of the Electric Power System Control and Operation Department at EIMV, Mag. Andrej Souvent addressed the participants and emphasised that the electric energy system (EES) transformation, boosted by mass integration of renewable dispersed sources of energy and new methods of using electric power, requires new concepts of planning, operation and management of the EES, as well as an enhanced development of new technologies, where information technologies take quite a large share. It also requires highly qualified experts and at the same time energy literate users, because in new concepts each user transforms from a passive to an active participant. "Education - on all levels - is of key importance for a successful implementation of the transition to a modern EES. It must be emphasised that the energy sector is becoming interdisciplinary, where the share of information and communication technologies, machine learning technologies and artificial intelligence is quickly rising," said Mag. Andrej Souvent. 

"Such events are an opportunity for the youth to get a direct insight in one of the fields of electrical engineering and are the result of excellent collaboration between the Faculty of Electrical Engineering," emphasised the Dean of the Faculty of Electrical Engineering in Ljubljana, Prof. Dr. Gregor Dolinar. 

The participants of the event also visited the exhibition entitled EIMV Over Time, prepared by the Milan Vidmar Electric Power Institute. The exhibition, which will be open until next year, presents EIMV over time, i.e. from its beginnings in 1948 until today. It also shows how EIMV was founded and at which important events it has collaborated. The exhibition also presents research areas of work and its role in the future.

A new method at the High Voltage Department

This year a new, very demanding testing method for the control of mineral transformer oils was introduced at the High Voltage Department.
This method involves the Partial Discharge Inception Voltage (PDIV) according to IEC 61294, which has been extended with measurements of some additional parameters for scientific and research purposes.

The measurement cell was produced in a Slovenian company according to the designs made by our engineers. The core element of the cell is the upper electrode – a pin with 1 mm diameter and a specifically determined point radius (3 µm), which must be replaced after each measurement. The pins are supplied by the Ogura Jewel Industry from Japan.

The Milan Vidmar Electric Power Research Institute has therefore become one of the rare global companies that implements this methods with the newest and modern equipment (no other institute is involved in such research in Europe).
