Abstract: In power system the power flow analysis (also known as load flow study) is an important tool used for analysis of power system. Load flow studies helps in determining the bus voltages, phase angles, active, reactive power, losses, power factor, etc. at different buses, generators, transformer in balanced and unbalanced conditions. For the analysis of load flow, methods generally used are Gauss-Seidel method, Newton-Raphson method and Fast Decoupled method. Newton-Raphson method is comparatively better for radial system hence; this method is identified for load flow analysis. Our scheme for load flow analysis is 11/3.3 kV Electricity Sub centre Padmapur W.C.L. Substation, Chandrapur for which all the parameters are calculated and compare with simulation results. ETAP (Electrical Transient and Analysis Program) software used for the simulation of scheme and the results from substation are compared with the simulation results.

Keywords: Load flow analysis, Electrical transient analyser program, Simulation, Capacitor banks, Voltage profile, Loss reduction.
