This can be defined in the load-flow page of the transformer. The attached example shows how to use a phase-shift transformer to control the active power shared between several transformers…

This can be modelled using an external tap controller or a master-slave mode. First of all, both transformers shall have a type which includes settings for the tap changer. In addition, the…

Firstly, it is considered a transformer that has a tap changer on the HV side, with a voltage source of 100 V on the HV. If the tap is on the position where the primary turns are np=50 then the…

This is possible by using a trick. Enter as the phase of the additional value an angle of phiu: phiu=180 degrees.…

The LDC is normally used in MV/LV radial networks to control the voltage at a remote end (by measuring the load current and compensating the voltage drop). A detailed explanation of the Line Drop…
