This model demonstrates the correct
behaviour of a transformer with a tap-changer logic of type
MAX.
The test circuit is composed by
a transformer whth a simple linear load. The transformer is
supplied by an ideal infinte bus with variable
voltage. The linear load
is obtained using a real bus with fixed voltage, the internal
impedance of the bus is used as linear load.
The voltage applied at the
transformer primary input has sinusoidal shape, the tap-changer
logic follows the shape of said voltage. The tap position starts to decrease when the
monitored voltage portB.U becomes higher than UMax threshold, and
stops when said monitored voltage reaches and stays under the UStop
threshold.
Values of voltages and and
transformer ratio for each tap position are not realistic, they are
just to show the tap changer logic behaviour.
