PSCAD is one of the specialized software in the field of electrical engineering used for the analysis and simulation of power circuits, providing responses in various transient and steady-state conditions. In this software, circuits can be designed, simulated, and executed schematically, and their responses can be analyzed. The software includes a library of pre-designed and tested models, comprising simple passive elements, complex controllers, electric machines, devices, and transmission lines and cables. Information in this software is presented in a fully graphical environment, allowing users to simultaneously draw diagrams and measure system variables. Users have the capability to design their required models from scratch using the software’s model library. The PSCAD software environment is entirely graphical, enabling users to draw their circuits using the powerful components available in the software library and view their required information in the software environment as variables or graphs. Features and capabilities of PSCAD software include:

• Resistance, inductance, and capacitance components
• Mutual inductance coil wires
• Presence of transmission lines dependent on frequency
• Analysis and simulation of power circuits, obtaining responses in various transient and steady-state conditions
• Voltage and current sources
• Switches and circuit breakers
• Protective relays
• Design of required models from scratch using the available program libraries
• Diodes, transistors, and GTO (Gate Turn-Off thyristor)
• Analog and digital controllers
• Design, simulation, and execution of circuits schematically and analyzing their responses
• DC and AC machines
• Models and tools for wind, turbines, and wind governors.
