  EDSA Power Flow Program

EDSA’s Advanced Power Flow (EAPF) program is one of the most powerful, fast, and efficient power flow programs ever created.

Equipped with an easy-to-use, intelligent graphical interface, the EAPF program supports advanced plotting, motor starting, numerous options and modeling features.

The EAPF program is based on advanced and robust solution algorithms that incorporate state-of-the-art solution techniques applicable to large and complex power systems.

    Power Flow results can be written directly on the one-line using the back annotation features or all of the solution quantities (voltages and flows) are exportable to Microsoft Excel, and can be used to customize reports using Professional Report Writer. Back annotation features can be enhanced by using the coloring feature.  
       

 
     
    Key Program Features:
  • Generator local/remote bus voltage control;
  • Four solution techniques: Newton-Raphson, fast de-coupled, hybrid solution, advanced Gauss Seidel;
  • Bus types can be defined as follows: “out of service,” “load,” “generator,” or “swing bus”;
  • Multiple swing buses/co-generation units;
  • Multiple independent islands;
  • Generator models can have different modes of operation: “fixed power output,” “fixed active power and control voltage at the terminal or at a remote location”
  • Two- and three-winding voltage control transformer models;
  • Transformers with fixed tap, voltage control, phase shifter (active power control), and reactive power control;
  • Transformers can be equipped with under load tap changers (ULTC) for local and remote bus voltage control
  • SVC “static-var compensation” and shunt capacitor and reactors;
  • “Area interchange control” allows many areas to participate in the area power interchange; each area will have a dedicated generator for controlling the tie line power;
  • DC lines and converter models;
  • No bus-numbering limitations;
  • Line voltage regulator (LVR);
  • Unlimited generators and/or motors schedules;
  • Transformer sizing through ADPF simulation.
