PSCAD/EMTDC is a general-purpose time domain simulation program for multi-phase power systems and control networks.It is mainly dedicated to the study of transients in power systems.A full library of advanced components allows a user to precisely model interactions between electrical networks and loads in various configurations. A graphical user interface and numerous control tools make PSCAD a convenient and interactive tool for both analysis and design of any power system.

PSCAD seamlessly integrated visual environment features all aspects of conducting a simulation, including circuit assembly, run-time control, analysis and reporting. Users can easily interact with the components during the simulation because of the variety of control tools. The solution meters and the plotting traces are also visible and available during the simulation. Signals can be analysed in real time.

PSCAD features a broad range of models for power system and power electronic studies such as:

  • Frequency dependent transmission lines and cables,
  • Transformers (classical model with saturation/Umec model)
  • Various machines, (synchronous, asynchronous, DC)
  • Various turbines (hydro, steam, wind),
  • Converters & FACTS,
  • Drive & control blocks,
  • Relays.
Fast and Accurate

The time steps interpolation technique combines accuracy and quickness: it allows the simulation to precisely represent the commutations of breakers and switches in the electrical model, for any model’s size, up to extremly large models. PSCAD results are solved as instantaneous values, and can be converted to phasor magnitudes and angles via built-in transducers and measurement functions such as true-rms meters or FFT spectrum analysers. The PSCAD simulation tool can duplicate the response of a power system at any frequency, because the computation step chosen by the user can go from several nanoseconds to several seconds.


PSCAD features multi-run capabilities, enabling a user to run a case multiple times with a set of parameters changed each time in a predetermined manner. This facility makes optimisation an easy game as the optimum results (according the criterion the users defines before) are highlighted by the software.


Create custom components? PSCAD features the built-in Component Workshop, the tool used to create all the Master Library components. The look of the components and the data forms are all designed graphically. It allows each user to easily create their own component library.

Power System Simulation for Engineering (PSS/E) is composed of a comprehensive set of programs for studies of power system transmission network and generation performance in both steady-state and dynamic conditions. Currently two primary simulations are used, one for steady-state analysis and one for dynamic simulations. PSS/E can be utilized to facilitate calculations for a variety of analyses, including:
PSS/E can be utilized to facilitate calculations for a variety of analyses, including:

  • Power flow and related network functions
  • Optimal power flow
  • Balanced and unbalanced faults
  • Network equivalent construction
  • Dynamic simulation

In addition, to the steady-state and dynamic analyses, PSS/E also provides the user with a wide rage of auxiliary programs for installation, data input, output, manipulation and preparation. Furthermore, one of the most basic premises of PSS/E is that the engineer can derive the greatest benefit from computational tools by retaining intimate control over their application.
Power Flow A power flow study (also known as load-flow study) is an important tool involving numerical analysis applied to a power system.
The PSS/E interface supports a variety of interactive facilities including:

  • Introduction, modification and deletion of network data using a spreadsheet
  • Creation of networks and one-line diagrams
  • Steady-state analyses (load flow, fault analysis, optimal power flow, etc.)
  • Presentation of steady-state analysis results

Power Flow A power flow study (also known as load-flow study) is an important tool involving numerical analysis applied to a power system. The PSS/E interface supports a variety of interactive facilities including:


The dynamic simulation program includes all the functionality for transient, dynamic and long term stability analysis. The dynamic simulation interface is operated as a separate program, currently independent of the PSS/E interface. This can be observed when going to a PSS/E program and viewing the dynamics as a separate program. The purpose of the dynamics is to facilitate operation of all dynamic stability analytical functions. The dynamics program, in addition to supporting the dynamics activities, also continues to support the traditional load flow interface through the LOFL(Load Flow) activity. This lab will not address dynamic simulations.
