User-Defined Dynamic Models Software - Dynamic Model Compilers


ETAP Graphical Logic Editor provides an interactive graphical environment and a comprehensive set of block libraries that let you design, simulate, implement, and test a variety of time-varying electrical power systems. The User-Defined Dynamic Model built-in compiling and testing capabilities include independent self-testing via load rejection, load acceptance, and terminal bus faults for validation of models and their dynamic behavior. Compilers include direct and iterative methods to assemble and integrate the models with ETAP transient stability software.
