ABSTRACT:
A plant for transmitting electric power comprises a direct voltage network for High Voltage Direct Current (HVDC) and at least one alternating voltage network connected thereto through a first station. The station transmits electric power between the direct voltage network and the alternating voltage network and comprises at least one VSC converter. The VSC converter converts direct voltage into alternating voltage and, conversely, alternating voltage to direct voltage. The alternating voltage network is a weak alternating voltage network, or a network without any generation of its own, and a large part of a load connected to the alternating voltage network consists of one or more electric motors.
