Course detail
Power Plants and Heating Power Stations
FEKT-MELEAcad. year: 2016/2017
The course deals with basic electrical equipment for power generation in conventional power plants and heating plants. Emphasis is put on the operating characteristics of synchronous machines that determine the way of power control in the electricity grid. Students learn the generator protections function and extend their knowledge of electrical machines through the measurement on the generator model in laboratory. Further section deals with an electrical power output of the generator and the devices for own power plant consumption.
