Plant for transmitting electric power to remote facilities which have an electric motor load
First Claim
1. A plant for transmitting electric power to a remote location comprising:
- a direct voltage network for High Voltage Direct Current (HVDC);
a weak alternating voltage network;
a power station having a VSC converter for connecting said weak alternating voltage network to said direct voltage network at a distance along said high voltage network remote from any other alternating voltage network, said VSC converter converting direct voltage from said direct voltage network to an alternating voltage, and converting alternating voltage from said weak alternating voltage network to direct voltage; and
a load connected to said weak alternating voltage network a substantial portion of which is provided by one or more electric motors.

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.
