Continuity of supply with electric energy by power system, crucial for personal, commercial and industrial activities, can be endangered by natural phenomena like lightning, wind, earthquakes, limited reliability of equipment or human errors. If energy is not delivered by a part of a second, it could be only annoying situation; if it this is lasting several hours blackout, it is a real disaster.
Such situations are prevented by extremely sophisticated protection equipment capable of sensing faults and coordinating operations necessary for preserving the supply continuity.
The Power System Protection Laboratory is equipped with the most advanced digital relays for protection of generators, transmission and distribution systems, as well as motors. The faults are modeled in the Lab with power system simulators capable of modeling power system response to any fault. A satellite synchronous clock enables synchronization of the Lab relays with events in any real power system. The Lab relays can be accessed via Internet, which enables their remote settings.
With the aid of analytic software, the Lab teaches students how faults affect the power system and provides them genuine knowledge on coordination of the protection relays to achieve the most reliable power system possible.
