The ability to analyze a power system is essential to power system engineers and
planners. The Bus program, a Microsoft Windows-based program, helps users make these
analyses. Unlike other power system analysis programs, the Bus program performs three
different types of analyses (short circuit, load flow, and state estimation) and offers users a
graphical interface on which to enter their system and data. This thesis presents the Bus
program and discusses various aspects of it, focusing on the load flow and state estimation
routines, which were the main thrust of the project. Each of these routines was written by
setting up a flowchart and defining the calculations to be carried out. Vehicles were then
developed so that users can enter system data and view the results of the calculations.
The ability to do this graphically is one of the main features of the program. Several test
cases are presented to demonstrate the program's operation, and a User's Manual is
included to show users how to operate the program.
