A computer program and an associated instruction manual were developed to fill a need for a useful learning tool for the study of transmission network power-flow programming techniques. Past programs were found to use techniques that did not give the student "hands-on" programming lessons, but instead gave them practice at using "pull-down menu" type of programming experience. The PFLOW program written is intended to be used "hands-on" with a complete instruction manual included to help the student use the program successfully and study the complete analysis technique. This includes network modelling, structure of input data, understanding program software, and correct meaning of outputs based on the complete knowledge of program solution methods. Sample input and outputs are also included to help get the student started, and to demonstrate the use of the PFLOW program. This program should prove beneficial to those with a general background in power transmission systems analysis.
