Engineering r Summary Introduction to the PSAT Internet community Installation Executing the PSAT GUI Mode Case study and data preparation How to set up a test system for power ow analysis Settings and power flow solution Viewing and analyzing results Questions Rensselaer Polytechnic Institute Electrical Computer and Systems Engineering Introduction What is the PSAT Is an open source power system analysis toolbox for Matlab and GNUOctave developed by Dr Federico Milano What is it used for It can be used for power system analysis and control learning education and research What is this presentation about Is about how to use PSAT from scratch to do simple power flow analysis What will you learn from this presentation This presentation does not intend to give you neither a complete nor solid understanding of the PSAT program It serves as a simple introduction to get you up and running with the program Rensselaer Polytechnic Institute Electrical Computer and Systems Engineering Internet Community The PSAT Forum is an internet community of developers program users and power system enthusiasts More than 1050 users around the world Part of the Open Source nature an philosophy of PSAT a spirit of collaboration You can get help and ask questions related to the PSAT and Power Systems knowledge Also download the most recent version of PSAT PSAT Documentation sample data les etc Hope to see you there httptechgroupsyahoocomgrouppsatforum Rensselaer Polytechnic Institute Electrical Computer and Systems Engineering Installation You will be provided a compressed tarball with the most recent distribution of the PSAT and the documentation You can alternatively download the PSAT from httpwwwpoweruwaterloocafmilano Uncompress the les and copy the psat folder preferably to the work directory in the Matlab directory It is advisable that you add the psat directory and its subdirectories to the Matlab Path Note the latest version of PSAT is only compatible with Matlab 7 R

must save the file and load it to PSAT it via the Data File field in the PSAT Main GUI This will translate your Simulink diagram to a PSAT readable data file We will cover how to use the GNE if you
