modelTCULController

Information

Common definitions for TCUL control systems according to [1].
Using the parameter the characteristics of the mechanical delay time (Tm)
and the controlled delay time (Td) the TCUL can be influenced according
to the table below:

----------------------------------
|method|    Td     |    Tm       |
----------------------------------
|  1   |  constant |  constant   |
|  2   |  inverse  |  constant   |
|  3   |  inverse  |  inverse    |
|  4   |  both     |  constant   |
----------------------------------

Use the subclasses TCULContinuous for continuous approximation (more computationally)
efficient or the the subclass TCULDiscrete for the true discrete realization.

The tap changer is locked if the primary side voltage decreases below the
tap locking voltage specified in Vblock.
