SVC converter with an extra phase leg to replace a failed phase leg
First Claim
1. A plant for transmitting electric power having an alternating voltage network having at least one phase and at least one VSC converter, said converter having at least one phase leg with two current valves connected in series, each said phase leg connected at a point between two said current valves to a respective phase, said plant comprising:
- at least one additional phase leg in said converter more than the number of phases of said alternating voltage network; and
means for disconnecting each phase leg from its respective phase and for connecting said additional phase leg at a point between its two current valves to said respective phase.

Abstract
A plant for transmitting electric power having an alternating voltage network with at least one phase and at least one VSC converter is provided. The converter has at least one phase leg with two current valves connected in series. Each phase leg is connected at a point between the two current valves to a respective phase of the alternating voltage network. The plant also comprises at least one additional phase leg in the converter more than the number of phases of the alternating voltage network and a means for disconnecting a phase leg from its respective phase and for connecting the additional phase leg at a point between its two current valves to the disconnected phase.
