Simulation of a Simple Power System using PSCAD
PSCAD is a powerful tool for simulation and analyzation of power systems. In this article, I'm going to create simulate simple power system which includes a power source, transmission line, and load.
First of all, we should create new PScad file. To create a new project, new → new project and add the project name. after pressing ok, there will be new canvas. other than the main canvas there is another canvas called ‘Master Libraty’
In the master library, there are components which we can use. To add source we should go to source panel, → more on sources and add the source we need.
After entering the sources, we can just copy and past elements from the main library to our canvas. After copying, we can rotate them by simply pressing ‘R’. in the same way we can copy our elements to the canvas. Also, there are shortcuts of frequently used components in ‘components tab’.
We can connect all the components using wires. To get wires, we can select it from components tab or we can use the shortcut ‘ctrl/cmd + w’. to connect, we can click at the starting point and click at the endpoint. To release the drawing tool at the endpoint, we should press the ‘ESC’ button. Here I’ve attached a voltmeter to measure the voltages and currents, active power and reactive power, etc.
These are the simulation results at load equals to 10 kilo-ohms.
Please note that here I haven’t included the variable linking procedure.
