摘要

A plant for transmitting electric power comprises a direct voltage network (1) for High Voltage Direct Current (HVDC) and at least one alternating voltage network (6) connected thereto through a first station (5), said station being adapted to perform transmitting of electric power between the direct voltage network and the alternating voltage network and comprising at least one VSC converter (10) adapted to convert direct voltage into alternating voltage and conversely and an apparatus (11) for controlling the converter. The alternating voltage network is a weak alternating voltage network or a network without any generation of its own, and a great part of a load connected to the alternating voltage network consists of one or more electric motors (7).
