description: In master thesis, the issues on design of power supply system for the catalytic cracking unit at oil refinery are considered.
Estimated object load is determined by methods of ordered diagrams and ac-cording to demand coefficient. Main electrical equipment is selected and checked with short circuit current analysis in the network up to and above 1 kV. All calculations are carried out on the basis of existing regulatory documents, taking into ac-count specifics and increased requirements for reliability of petrochemical industry power supply system.
Circuit design is substantiated based on calculation of center of electric loads, issues of equipment layout are considered, and decisions on reactive power compensation and relay protection are made. Special attention is paid to the safe operation of electrical equipment.
This applied research is carried out as part of real existing object reconstruction. A number of technical solutions adopted during the study are used at the design stage of this unit.
