Abstract
Disclosed is a device for controlling a terminal connected in a multi-terminal high-voltage direct current transmission facility, the terminal being able to provide or draw power on the DC part of the facility comprised between an upper power limit and a lower power limit, the device further comprising at least one regulation circuit configured to vary the power provided or drawn by the terminal on the DC part of the facility, as a function of a voltage variation on the DC part of the facility, the device further comprising a limitation circuit configured to limit the variation of the power provided or drawn by the terminal, for a given voltage variation, when the power difference between the power provided or drawn by said terminal and the upper power limit or the lower power limit becomes smaller than a determined value.
