modelLoadAlphaBetaRestorativeNetwork
Generic model of a restorative Alpha-Beta load, same model as in the Network.
Extends from BaseClasses.BaseLoad (Base model for loads), AdditionalIcons.Load.
Information
After an event, the load goes back to its initial PPu/QPu unless the voltage at its terminal is lower than UMinPu or higher than UMaxPu. In this case, the load behaves as a classical Alpha-Beta load.This load restoration emulates the behaviour of a tap changer transformer that connects the load to the system and regulates the voltage at its terminal.
