RELATING TO CONNECTING A DC CONVERTER TO A DC SYSTEM IN POWER TRANSMISSION NETWORKS

A method for connecting a DC converter to a DC system using a connection circuit, the connection circuit including a first switch connected in series between the DC converter and a second switch, the second switch connected in series between the first switch and the DC system, and a resistive component connected in parallel with the second switch. The method includes operating the first switch from the open configuration to a closed configuration, such that a first current is able to flow through the connection circuit; determining the first current flowing through the connection circuit; adjusting a DC converter voltage of the DC converter, as a function of the first current, to reduce the first current through the connection circuit to or below a threshold value; and then operating the second switch from the open configuration to a closed configuration, thereby connecting the DC converter to the DC system.
