Hodnocení systému automatického rychlého záskoku

Abstract

In this thesis I deal with the system of the electricity supply to unit and shared substations 6kV of internal consumption which supply technological systems of the generating units and shared facilities of the thermal power station (thermal power plant) Tušimice II. Here I describe possible connection alternatives of these 6kV substations. Releasing factors caused by fault events of the block or line protections are defined. I analyse the process of fast (hot) automatic standby from the perspective of reliability of the recovered objects. I also examine here influences of the possible risks on the technological processes. Another, new possibilities for the development of the system functions are proposed. Finally, evaluation results and potential risk factors are presented.
