摘要：The invention relates to a method for protecting a network comprising: -electrical lines (120, 130, 230); -three nodes (10, 20, 30) for interconnection with: -a high-voltage interface with controlled switches; -a local network interface; -local networks foreach respective node (10, 20, 30), comprising: -an MMC converter (16, 26, 36); -a protectivecircuit with, in parallel, a first controlled switch (14) and a first limiter (15), a secondcontrolled switch (12) and a second limiter (13). The method comprises the steps of: -keeping said first switches (14) closed and said second switches (12) open; -measuringvoltage and current at the high-voltage interfaces; -communicating the direction of thecurrent, to the other end of a high-voltage line; -for each node: -identifying a fault; -checking that the current is lower than the breaking capacity of the high-voltageinterface switch and opening this switch.
