Chair of Power Systems and Substations

The Chair of Power Systems and Substations is planning the following activities:

  1. Application of smart grids in terms of transmission and distribution networks as well as developing micro networks. We are planning to integrate renewable energy power plants in power engineering system by using smart grids. It is essential to use the knowledge and new results about the integration of renewable energy power plants in power engineering system in classes. Additionally, the Chair is planning to apply for the EU projects (ITEA2) which might be multidisciplinary since smart grids use the newest ICT technologies.
  2. Application of modern teaching methods and algorithms for electrical energy market education, setting EU standards and regulatory rules from the field of electrical energy market into teaching thematic units.
  3. The Chair of Power Systems and Substations plans to apply for the scientific-research EU project together with the partners (e.g. HEP-NOC) from both the Republic of Croatia and the Republic of Slovenia. The project will deal with the knowledge transfer and technology of work under voltage resulting in introducing an elective course at the graduate study.
  4. We will develop and introduce thematic units related to SF6 GIS and HIS systems in our classes. Additionally, we plan to introduce units about modern FACTS systems in power networks with the aim of enhancing stability, voltage regulation and losses reduction in power engineering system.
  5. Regarding the protection in power engineering system, we are planning to open a laboratory and educate a laboratory technician who will work with modern numerical relays.
  6. Two assistants from the Chair of Power Systems and Substations will get their doctoral degrees and will be promoted to assistant professor in five years period. Two new assistants will be employed. Otherwise, the Chair and the Department will not be able to perform their teaching activities.

 

Chair of Power Plants and Energy Processes

Plans to be realized are the following:

  1. Within the IPA project REGPHOSYS Photovoltaic systems as actuators of regional development, the Laboratory for Renewable Energy Sources has been established. Classes and scientific-researches will stem from the results obtained in the laboratory. The laboratory consists of the photovoltaic laboratory for measurements and analysis of the effect on the network of different photovoltaic types and converters. Our colleagues from the Department of Electromechanical Engineering who participated in the project can also use the laboratory.
  2. New scientific-research projects, development of new applications and the integration of distributed production from renewable energy sources into advanced (micro) networks are planned. The latter will be especially oriented towards the region of Slavonia and Baranja. We are planning to develop models and patents of small biomass and biogas power plants as well as wind power plants for exploiting the maximum energy of lower wind speed.
  3. We plan to develop the Laboratory for Energy Efficiency that will be able to deal with all challenges. The laboratory will be used to educate engineers in the field of energy efficiency. Additionally, it will be a support for local business subjects regarding measurements as well as an assistance in making crucial decisions.  
  4. The Laboratories will eventually develop into a regional centre for the application of renewable energy sources and energy efficiency. Together with research, the centre will provide life-long education in accordance to the needs of business sectors. Programmes development will be funded by available European funds resources.
  5. We are planning to adjust the existing courses and eventually develop a new graduate or postgraduate study in the field of sustainable power engineering where the emphasis will be on renewable energy sources, energy efficiency and environment protection. Given the multidisciplinary nature, we are planning to cooperate with other constituent units (e.g. Faculty of Mechanical Engineering, Slavonski Brod) and other experts from the field of ecology.
Electromagnetic Compatibility Laboratory

Plans to be realised:

  1. Measurements of low frequency electrical fields and energy quality are performed in the Electromagnetic Compatibility Laboratory. EMC Laboratory is used by the sub-departments of the Department of Power Engineering. In addition, external subjects may also use the EMC Laboratory. Hence, we are planning to improve our teaching contents and activities, participate in scientific and EU projects and upgrade our measuring services themselves.  
  2. We are going to make teaching materials for laboratory exercises within the course Voltage quality in power engineering system. Furthermore, we have already been working on updating the course Designing electrical installations and facilities. We have currently been working on introducing new teaching materials. After we had purchased EPLAN Electric P8, we started working on new teaching materials. Finally, we are going to introduce new contents related to energy efficiency and lightning in the course Installations and lightning.
  3. Scientific projects done by the Department of Power Engineering regarding renewable energy sources, energy efficiency, smart grids, smart installations, etc. will be conducted in the Laboratory.
  4. EMC Laboratory plans to become more competitive in the market. Collaborating with the Photovoltaic Measurements Laboratory, we have started working on new marketing materials and the EMC Laboratory website.
  5. According to the market needs, we are planning to expand our accreditation rights to calculating electric and magnetic fields, hence we are planning to purchase software for calculating electric and magnetic fields.
