Keywords:industrial power systems, load flow, power system planning, Power system reliability, substations
This paper presents a comparative analysis for two alternatives of industrial substation arrangement with selective secondary radial type: first with one main transformer and one reserve and the second one with two main transformers and one reserve. The methodology is based on the power flow calculation, short circuit and reliability indices using the Electrical Power System Analysis Software (ETAP) and on the acquisition costs of equipment and materials. The methodology application in both alternatives is presented and the results are analyzed and compared as well.
