Design of electrical system based on load flow analysis using ETAP for IEC projects

This paper explains about performing load flow analysis using ETAP for IEC projects and selection of electrical equipment parameters based on ETAP result. Load flow analysis is the basic analysis for electrical power system design, electrical power system planning, etc. This paper discusses about input required for modeling electrical system, standard/typical values of input, values to be assumed if input is not available, acceptable limit of load flow analysis result and methods to be followed to achieve correct result. All the power system equipments are designed to withstand worst case conditions. This paper also discusses about certain worst cases to be analyzed using load flow analysis.
