  EDSA Advanced Transient Program

EDSA’s Advanced Transient program is a powerful simulation software program for assessing the dynamic behavior of electrical power systems when subjected to disturbances.
   
  Fast, robust and reliable program is fully-integrated with EDSA’s Universal Control Logic Simulator (UCLS) offering an intuitive, easy to use, graphical dynamic machine model-building environment for user defined AVR and governor models
