Design of MV switchgear used for laboratory purpose

Abstract

Within the cooperation between Technical University of Ostrava and ABB European operation center in Ostrava was completed a project of detailed design of the substation that should serve in purpose of science as a laboratory unit. This work contains a description of the main stages completed during the execution of the project. The first half is devoted to the theoretical aspects necessary for this project, and the second half considers all the main design steps directly. The main attention is paid to the design of the substation control system, namely, the development of the control cabinet. The basic aspects of the interlocking concept and protection functions were considered as well.
