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 signals 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.
