  EDSA Advanced Motor Starting Program

EDSA’s Advanced Motor Starting program (EAMS) is a powerful, fast, and efficient program that supports advanced plotting, numerous options and modeling features.

The program is based on advanced and robust solution algorithms, that incorporate state-of-the-art solution techniques applicable to large and complex power systems. The program is equipped with an easy-to-use and intelligent graphical interface to enhance user productivity.

Induction Motor Dynamic Data

 
     
    Key Program Features:
     
  • Individual dynamic motor starting;
  • Simultaneous multi-motor starting;
  • Four solution techniques: Newton-Raphson, Fast De-coupled, Hybrid Solution, Advanced Gauss Seidel;
  • Automatic voltage control: transformer tap, generator voltage control, static VAR compensation;
  • No bus-numbering limitations;
  • Including or not the power source impedance;
  • Motor starting feature based on IEEE Brown Book including a variety of the latest solid-state/soft-state motor start controllers: full voltage, full voltage square, wye-delta, auto-transformer, part winding, series resistance, series reactance, shunt capacitance, solid state voltage control, solid state current limit, solid state current ramp, solid state voltage ramp, solid state torque ramp, variable frequency drive, VFD with constant U/Hz.
  • User-selectable options to switch from one starting method to other method;
  • All of the solution quantities (voltages and flows) are exportable to Microsoft Excel, and can be used to customize reports using Professional Report Writer;
  • Display the motor starting results directly on the one-line diagram (simultaneous multi-motor starting option);
