Course detail
Distribution and Industrial Networks
FEKT-MKC-MEZAcad. year: 2022/2023
The course deals with operation of distribution and industrial networks, both viewpoints of requirements for power quality and of the reliability of supply. The ways of operating and fault conditions of these networks and their protection are explained, as well as problems of distributed generation sources connection. Part of the course is devoted to the currently used standards for evaluating the reliability of power supply.
