The first upstream power converter has at least one first AC terminal electrically connected with a first AC power source. The bipole power transmission network includes a second upstream power converter which has a third DC terminal that is connected with the return conduit, and a fourth DC terminal which is connected with a second transmission conduit that extends, in-use, to the second downstream power converter, and at least one second AC terminal electrically connected with a second AC power source.

Abstract: A voltage limiter includes first and second DC terminals connectable to a DC power transmission medium and ground, respectively. The voltage limiter further includes: (1) a current transmission path including two portions connected in series between the terminals and each including a non-linear resistive element; (2) a current bypass limb connected in parallel with the second portion and including at least one switching element; and (3) a control unit configured to control switching of the or each switching element to selectively switch the current bypass limb, during a fault condition, from a first mode to a second mode. In the first mode, current flows through the current bypass limb and bypasses the second current transmission path portion. In the second mode, current between the DC terminals is inhibited from flowing through the current bypass limb and thereby permits the current to flow through the second portion.

Abstract: A voltage source converter includes first and second DC terminals which have at least one converter limb extending therebetween. Each limb portion includes a chain-link converter that extends between an associated AC terminal and a corresponding one of the first or the second DC terminal. Each chain-link converter also includes a chain-link converter controller which is programmed to control a series of connected chain-link modules. The voltage source converter additionally includes a voltage source converter controller which is arranged in operative communication with each chain-link converter controller to coordinate operation of the chain-link converters. Each chain-link converter controller is further programmed to reconstruct from a received modulation index demand the chain-link converter voltage reference, which the chain-link converter it is controlling is required to produce, by multiplying the received modulation index demand by a total voltage sum established at a first time instant.

Abstract: An assembly including a converter including first and second DC terminals connectable to the DC network and between which extends a converter limb. Each converter limb includes first and second portions separated by an AC terminal. Each portion includes a switching element for normal operation and a switching element and energy absorber for a bypass mode. The bypass mode causes current to bypass the energy absorber in the limb portion and flow through the energy absorber. The assembly also includes an AC circuit breaker which is openable to isolate the converter from the network. The electrical assembly includes a control unit that is a programmed to operate the energy absorption module within the converter in its bypass mode and following a DC fault to initiate opening of the AC circuit breaker then to operate in absorption mode to remove DC fault current within an augmented current path.

Abstract: A method and apparatus for controlling a voltage source converter to energise a DC link. A voltage order generating module generates a voltage order for controlling the voltage source converter to generate a DC voltage on the DC link. An oscillation damping module monitors the DC current flow to determine an indication of current oscillation and the voltage order is based on a voltage reference signal which is modulated by the indication of current oscillation to provide oscillation damping.
