Subject description
Protection and control equipment in power systems, power system protection principles, redundancy, features of protective relays, current and voltage transformers, protection of generators, transformers, lines, numerical (digital) protection, wide area protection.
Elements of power system control, databases, SCADA systems, communication, signal processing, automation of power systems, frequency and voltage regulation, control functions (network, production, consumption, reliability of supply, simulator, other control functions), control management (control levels – OSI model, configuration of control systems, control and maintenance), standards and protocols, control equipment.
The subject is taught in programs
Objectives and competences
Students will become familiar with basic principles in the field of power system protection and control, basic physical principles of different phenomena in power systems, development of technologies in the field of protection and automation, protective solutions of different elements, wide area protection systems, the role of measurement transformers (current and voltage), protection redundancy, control functions, databases, signal processing, communication technologies, standards and protocols.
Teaching and learning methods
Lectures and exercises.
Expected study results
After successful completion of the course, students should be able to:
– develop mathematical models for all types of short circuits occurring during power system operation,
– describe physical phenomena in devices during short circuit occurrence,
– interpret basic principles of protection of individual devices or set of devices and control systems,
– conceptualization and realization of protective and control systems and automation of power systems,
– explain and upgrade automation and control function in the practice.
