摘要

The invention relates to a method for controlling a high-voltage direct-current network (1) comprising: - high-voltage power lines (121, 123, 131, 133, 231, 233); - first to third conversion stations (11, 12, 13) each comprising: - a direct-current network interface comprising first and second poles (141, 142, 143); - at least two AC/DC converters (101, 102) connected between the alternating-current network interface and the direct-current network interface; - a control device (15) accessing a database storing a maximum intensity value at the nominal voltage and the corresponding growth time for each of the converters; - the control device determines an increased power to be exchanged for compensation on the second pole of the stations in the event of a fault on one of the high-voltage lines connected to the first pole based on the defective pole and based on the values stored in the database.
