Abstract

The purpose of this work is to create a laboratory task using ABB REF630 protection, which is located in the laboratory of the Faculty of Electrical Engineering and Computer Science of VŠB-TUO. The theoretical part discusses the different protections used in distribution and transmission systems and the requirements placed on them. Then the thesis focuses on the description of the REF630 protection, especially on its DSTPDIS distance block. The next part of the thesis deals with the creation of a laboratory task for students. The procedure and wiring of the REF630 protection for the use of its spacer block is developed. Students first simulate a three-section line where they use the protection to measure the values to set the distance block. From the measured values, they will calculate the necessary parameters to build a tripping plan for the distance protection for the 3 protected zones. Using the fault module, they simulate short circuits on each section to verify the correctness of the settings. At the end of the work a sample protocol is created.
