Tap Changer Blocking 1 (TCB1)

Extends from BaseClasses.BaseTapChangerBlocking (Base model for Tap Changer Blocking (TCB)).

Information

This model will send a block order to transformers with tap-changers to block the tap to its current step if the voltage becomes lower than a threshold on one controlled node. Such a mechanism enables to avoid voltage collapse on situations where the tap actions become negative for the system stability.

The detailed tap-changer-blocking behavior is explained in the following state diagram:
