Hello everybody,
Does anybody know how to tune the controllers "DC Voltage Control Override" and "AC Voltage Control Override"? They are both included in the demo about VSC-HVDC link.
Thanks, Ana

In the documentation "VSC-Based HVDC Link", we can read:
_[...] The AC Voltage control override block, based on two PI regulators, will override the reactive power regulator to maintain the PCC AC voltage within a secure range, especially in steady-state.
[...] The DC Voltage control override block, based on two PI regulators, will override the active power regulator to maintain the DC voltage within a secure range, especially during a perturbation in the AC system of the station controlling the DC voltage._
You can adjust the PI regulators and their range of operation in the VSC Controller mask.
