Power flow calculation is very important for power system operation, economic scheduling and planning. This paper presents gives information about a development of Power System Load Flow Analysis tool based on the Newton Raphson method. This tool introduces a simple interface for the user to perform load flow analysis. It is also designed for a user to view power flow results for each iteration and thus will facilitate especially undergraduate electrical students to verify their manual calculation of load flow solution. By just point and click, the students will easily get the required solution. The load flow tool is evaluated by solving the load flow of several test systems including IEEE bus system. For every required calculation steps for Newton Raphson load flow are successfully verified with the manual calculation and load flow solution in Power World Simulator and VBA Excel. Thus, this tool helps student and lecturer to learn and verify their manual calculation and at the same time reduce their calculation time.
