Step by Step Procedure to Run a Power Flow Simulation Using PSSE

The Siemens - PTI PSSE power flow simulator is a well known and reliable power flow simulation tool for simulating power systems of up to large scale in size. However, just like other sophisticated analysis tools, it’s hard to learn the basics of using it, specially, for the new user of the software.

Below is a simple tutorial and procedure of constructing a single line diagram, and how to run a power flow using PSSE. I will be using version 30.2 in this tutorial.

1. Run the PSSE power flow module, PSSE (Power Flow)

2. In the menu bar, click “File” then “New”. A dialog box like this should appear:

Select “Case” then press “OK”.3. If a “Build New Case” Dialog box appear. Set the Base MVA to 100 MVA, then, press “OK”.

4. A spreadsheet will appear. This is where you will input all the data necessary for the simulation of the system. Save this file as a “.sav” file.

5. At “Bus Number” Column, input “1″, then, move on the next row using the arrow key in your keyboard. This step is just to put an initial value in the spread sheet. A part of the spreadsheet should look like this:

6. Do step number 2, but this time, choose “Diagram” then, click “OK”. Save this diagram in whatever name that you want.7. In the “activity tree”, in the left side of the interface, go to Network -> Buses folder, and click on the content of the “Buses folder”, similar to this:

Then, click the auto draw icon:

And, click on the diagram where you want to put the bus drawing.8. You should come up with the schematic representation of a bus in the diagram interface, similar to this:

This is where you are going to start in drawing the single line diagram. You can now use the traditional drag and drop in drawing. To edit the data, just double click the section that you want to edit. When double clicked, the spread sheet containing the information of the diagram will appear. This is where you are going to edit the information in the single line diagram.9. To pan, just click:
