To maintain the generation of electric power at adequate level the power has to be transmitted in proper form and quality to the consumer. Open access transmission has created a deregulated power market and brought new challenges to system planning. This paper proposes a new method to compute a probabilistic load flow in extensive power systems for the purpose of using it as a quick screening tool to determine the major investment on improving transmission system inadequacy. This research paper deals with the simulation of 132 kV substation in Electrical Transient Analyzer Program (ETAP) with detailed load flow analysis and also to overcome the problem of an under voltage. The results are based on actual data received from 132 kV Hingna II substation. Keyword— Load Flow,ETAP software, reactive power , Buses, voltage profile. I. INTRODUCTION The Power Station Load Flow Analysis program calculates the bus voltages, branch power factors, currents, and power flows throughout the electrical system. The program allows for swing, voltage regulated, and unregulated power sources with multiple utility and generator connections. It handles both radial and loop systems. Table 1.1:-Load flow studies The Display Options section explains what options are available for displaying some key system parameters and the output results on the one-line diagram, and how to set them. The Load Flow Calculation Methods section shows formulations of different load flow calculation methods. Comparisons on their rate of convergence, improving convergence based on different system parameters and configurations, and some tips on selecting an appropriate calculation method are also found in this section. The Required Data for Calculations section describes what data is necessary to perform load flow calculations and where to enter them. Finally, the Load Flow Study Output Report section illustrates and explains output reports and their format. II. Load Flow Using Electrical Transient Analyzer Program (ETAP) ETAP Load Flow software performs power flow analysis and voltage drop calculations with accurate and reliable results. Built-in features like automatic equipment evaluation, alerts and warnings summary, load flow result analyzer, and intelligent graphics make it the most efficient electrical power flow analysis tool available today. ETAP load flow calculation program calculates bus voltages, branch power factors, currents, and power flows throughout the electrical system. ETAP allows for swing, voltage regulated, and unregulated power sources with unlimited power grids and generator connections. This load flow calculation software is capable of performing
