Development of an Interactive Program to Study of the Continuation Power Flow

The purpose of this paper is develop an interactive program to study of the continuation power flow. Both, the graphical user interface and the power flow program have been developed in the Matlab environment and it allows the direct change of information between both. Besides, it provides not only a good computational performance, but also an users-friendly teaching software. With the use of this interactive program the user is liberated to edit the input and output data files of the selected systems and can visualize and analyze the results of the program directly in the computer screen. Directly from the system one-line diagram, the graphical interface allows the user change the parameters of the system (bus and lines system data); remove the transmission line clicking directly on it; view the buses voltage profile, and the real and reactive power flows. In addition, the user can obtain all the P-V curves of pre and post-contingency loading margin. All these characteristics make the developed program recommended for educational purpose.
