This model demonstrates the correct
behaviour of a transformer with a tap-changer logic of type
INTERVAL.
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 a sinusoidal shape, the tap-changer
logic follows the shape of said voltage. The tap position decreases when the monitored
voltage portB.U becomes higher than UMax threshold, and increases
when said monitored voltage becomes lower than UMin
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.
