Information

In this test case, the interaction between a phase shifter transformer and an HVDC line is shown.

For that an HVDC line parallel to the lineB29B52 is added to the original IEEE 57-bus model and the transformer TfoB7B29 is modeled as a phase shifter transformer monitering TfoB7B29.P1Pu.

At t = 150 s, the lineB29B52 is disconnected. It means that the current now will pass through the HVDC line.

Also, the monitored value of the power falls below the minimum range, so the phase shifter will have to react after 25 seconds if PMonitored < PMin.

Meanwhile the power passing through the HVDC in AC emulation is increasing.

After 25 s, the phase shifter passes a tap, that changes the phase, resulting in the increase of power.

With the dynamic of the HVDC, PMonitored is between the accepted range.
