ETAP SOFTWARE BASED TRANSIENT, GROUND GRID AND SHORT CIRCUIT ANALYSES OF 132 KV GRID

Faults always contribute significantly in disturbing the reliability and security of an integrated electrical power system. This requires the considerable attention of researchers and power industry stake holders to address these issues using latest instrumentation techniques. For this purpose a practical power system of 132 kV Grid has been selected for comprehensive analyses using Electrical Transient Analyzer Program (ETAP) software for Transient, Short circuit and Ground Grid analyses. In Transient analysis different waveforms like variation in bus frequency, bus real power loading, bus voltage angle and bus reactive power loading have been recorded for short interval of time. During Ground Grid modeling which is based upon practical data, step and touch potential have been calculated in comparison with set standards. While performing short circuit analysis all the possible short circuit faults like line to ground, double line to ground 3‐phase faults etc on 12 cycle, 1.5 to 4 cycle and 30 cycle netwo...
