<p>In a plant for transmitting electric power between a direct voltage network (1) and a alternating voltage networks (6, 7) through VSC-converters (8, 9) a first station (5) for transmitting electric power is in voltage regulating mode. Switching members (12, 13) are adapted to be alternatingly switched in and out upon occurrence of a sudden change of power of the second station (4) so as to alternatingly connect one of the poles (2, 3) of the direct voltage network through an associated resistance (14, 15) to ground. A ground current generated therethrough is detected by a ground current measuring member (22) of the first station (5), which is therethrough informed about said unbalance. <IMAGE></p> |
