Through the Electrical Transient Analyzer Program (ETAP) software, an in-depth load flow analysis of an operational substation belonging to Delhi Transco Ltd. has been conducted. Initially, a simulation model of this specific transmission 220/66 kV substation has been designed, in which each component is configured based on real-world data. Several simulation scenarios including short circuits, and transient conditions have been considered by replicating real power system operating conditions. A load flow analysis has been performed with the values of suitable parameters thoroughly observed and recorded. The assessment of the model is carried out by comparing simulation outcomes with actual substation data. Furthermore, for a comprehensive examination, frequency and harmonic analyses at different bus points have also been performed. Inference of the system behavior is drawn from simulation results. Finally, conclusions are drawn and prospects for further work are discussed.

摘要

Through the Electrical Transient Analyzer Program (ETAP) software, an in-depth load flow analysis of an operational substation belonging to Delhi Transco Ltd. has been conducted. Initially, a simulation model of this specific transmission 220/66 kV substation has been designed, in which each component is configured based on real-world data. Several simulation scenarios including short circuits, and transient conditions have been considered by replicating real power system operating conditions. A load flow analysis has been performed with the values of suitable parameters thoroughly observed and recorded. The assessment of the model is carried out by comparing simulation outcomes with actual substation data. Furthermore, for a comprehensive examination, frequency and harmonic analyses at different bus points have also been performed. Inference of the system behavior is drawn from simulation results. Finally, conclusions are drawn and prospects for further work are discussed.
