The ETAP User-Defined Dynamic Models program can be used to build or customize complex machine control system. This module allows you to build control block diagrams needed to simulate the behavior of machines in Transient Stability and Generator Start-Up simulations. The User-Defined Dynamic Models provides independent self-testing via load rejection, load acceptance, and terminal bus faults for validation of models and their dynamic behavior. The main application of the UDM module is to model dynamic control elements which are not part of the standard ETAP dynamic model library.

User-Defined Dynamic Models software is fully integrated into ETAP and allows the creation of dynamic models without the need to buy additional MATLAB Simulink® software.

The User-Defined Dynamic Models software consists of Graphical Logic Editor (GLE) that allows you to build control transfer function block diagrams. The User-Defined Dynamic Models software also includes a detailed compiler with comprehensive initialization routines that allows you to utilize control block diagrams to simulate dynamic response to power system disturbances via Transient Stability software.
