Abstract: Power flow analysis is the backbone of power system analysis and design. They are necessary for planning, operation, economic scheduling and exchange of power between utilities. The principal information of power flow analysis is to find the magnitude and phase angle of voltage at each bus and the real and reactive power flowing in each transmission lines. Power flow analysis is an importance tool involving numerical analysis applied to a power system. In this analysis, iterative techniques are used due to there no known analytical method to solve the problem. To finish this analysis there are methods of Mathematical calculations which consist plenty of step depend on the size of system. This process is difficult and takes a lot of times to perform by hand. The objective of this project is to develop a toolbox for power flow analysis that will help the analysis become easier. Power flow analysis software package Develops MATLAB programming and MATLAB GUI. I have used NEWTON-RAPHSON method to find the unknown parameters of 5 BUS systems. The power flow computation consists of imposing specified power and voltage input conditions to a power network and producing the complete voltage information at all the system buses. The calculation is required for both the steady state analysis and the dynamic performance evaluation of power systems.3The paper also describes the undergoing integration and initialization of the well-known system software MATLAB with the load flow program.
