User Defined Models

In general the user-defined modelling (UDM) tools are used for detailed modelling of machine controllers, such as AVRs and Governors. Using the special “universal” machine UDM models can directly control the real and reactive current or power injections onto a busbar based on network conditions.UDM application

The UDM application uses a graphical control block diagram to model controllers, so no coding ability or third-party compilers are required for users.
