Abstract:
The present invention provides a method of MMC for HVDC. According to the present invention, there is provided a redundancy control method of an MMC for HVDC, wherein the MMC includes multiple converter arms each has multiple submodules in operation and redundancy modules for spares, the method including: checking whether a breakdown of a submodule in operation of a first converter arm among the multiple converter arms occurs in a case where the all redundancy modules of the first converter arm are applied in operation; and lowering an output voltage of each submodule of other converter arms in such a manner that a DC link voltage of each of the other converter arms is controlled to be equal to a DC link voltage of the first converter arm when the breakdown of the submodule of the first converter arm occurs.

Claim (Index 1):
A redundancy control method of an MMC for HVDC, wherein the MMC is connected to HVDC and is composed of multiple converter arms each including multiple submodules and redundancy submodules, the method comprising:\n checking whether a breakdown of a submodule in operation of a first converter arm among the multiple converter arms occurs in a case where the all redundancy submodules of the first converter arm are applied in operation; and controlling a DC link voltage supplied to the multiple converter arms to be equal to a sum of output voltages of the submodules of the first converter arm except for the submodule which has broken down and lowing an output voltage of each submodule of other converter arms according to the DC link voltage when the breakdown of the submodule in operation of the first converter arm occurs.
