Power flow computation of a distribution system is very important for the system operation, reconfiguration and for placing the FACTS devices. This paper presents a development of distribution Power System of Radial Distribution Network with laterals Load Flow Analysis tool based on the Tellegen theorem based method by using a User Friendly Graphical User Interface (GUI) Matlab Program. 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 and the GUI tool gives the complete Voltage Profile and Power Losses in the system.The well proved Tellegen theorem is used to obtain the load flow solution of Radial Distribution Network. 12.6KV Distribution system for 12, 28, 33 and 69 bus system..The result shows that all the answers displayed in GUI for every required calculation steps for Tellegen theorem based load flow are successfully verified with the manual calculation Thus, this tool helps student and lecturer to learn and verify their manual calculation and at the same time reduce their calculation time.
