EMTDC now serves as the electromagnetic transients solution engine for the PSCAD family of products. PSCAD is used extensively for many types of AC and DC power simulation studies, including: Power electronics (FACTS), sub-synchronous resonance and lightning over-voltages (to name a few).

Typical EMTDC Studies
EMTDC (with PSCAD) is used by engineers and scientists from utilities, manufacturers, consultants, and research/academic institutions, all over the world. It is used in planning, operation, design, commissioning, tender specification preparation, teaching, and advanced research.
The following is a sample of the types of studies routinely conducted using EMTDC:
Contingency studies of AC networks consisting of rotating machines, exciters, governors, turbines, transformers, transmission lines, cables, and loads
Relay coordination
Transformer saturation effects
Over-voltages due to a fault or breaker operation

Component source is inserted in either DSDYN or DSOUT, depending on what the component is connected to. Decisions are made by an involved internal algorithm in PSCAD, which ensures that both feedback and feed-forward **s are properly sequenced, minimizing time delays. However, component source may also be forced into either DSDYN or DSOUT at the user’s discretion. To force source into a specific subroutine, use either the DSDYN or DSOUT segments. To utilize the internal algorithm, use the Fortran segment. For more details on these segments, see the section called Segment Types in the Component Design chapter of the PSCAD Manual.
Example on Time Delays and Code Placement
As mentioned above, it is important to establish the proper use of DSDYN and DSOUT to avoid unnecessary time step delays. Meters used for the measurement of voltage and currents for example, are primarily defined in DSOUT: This is the logical subroutine to choose, as DSOUT will supply the measured quantities directly following the network solution. However, measured quantities are often used as inputs to control systems, where the individual control components are defined in DSDYN. Since there is a time step increment between DSOUT and DSDYN, the control system may be basing outputs on quantities defined in the previous time step.
