Power Distribution and Industrial Systems

Subject description

Basics of distribution and industrial networks: basic configurations, voltage levels, distributions and transformation stations, rural and metropolitan area networks, practice in Europe.

Electrical equipment in distribution and industrial networks: transformers, transformer connections and earthing, overhead and cable networks, industrial networks, switching devices, switchgear, compensation devices, loads and their characteristics, selection of proper equipment.    

Operation of distribution and industrial networks: local standards, voltage drop, voltage regulation, faults in distribution and industrial networks, influence of network parameters and earthing on fault currents, protection devices, lightning protection, and specificities of industrial networks.

Safety for users: basic operating and grounding modes of distribution and industrial networks from the safety viewpoint, earthing of transformers, generators and loads, safety risks for users, touch and step voltage, protection measures.

Distributed generation: integration of distributed and industrial generation units into distribution and industrial networks, influence of distributed generation on network behaviour, island operation with distributed and industrial generation units, stability and reliability of networks in island operation, using load shading, problems connected with networks in island operation mode. 

The subject is taught in programs

Objectives and competences

The student will learn about the basic characteristics of distribution and industrial networks. During the lectures he/she will be acquainted with the characteristics of electrical equipment used in these networks and will learn how to select the appropriate equipment according to the network parameters and loads. During exercises he/she will learn how to perform basic calculations of conditions in the network. Students will also be aware of the risks for the users of these networks and will be familiar with appropriate safety measures.

Teaching and learning methods

Lectures, exercises. Part of the pedagogical process will be carried out with the help of ICT technologies and the opportunities they offer.

Expected study results

After successful completion of the course, students should be able to:

– list the elements of the distribution and industrial networks and describe their characteristics;

– explain the operation of distribution and industrial networks;

– interpret different contingencies in distribution and industrial networks;

– select suitable equipment for use in distribution and industrial networks;

– calculate voltage drops and short-circuit currents in distribution and industrial networks;

– design simple distribution and industrial networks.
