Abstract:
A method of discharging a Modular Multilevel Converter (MMC) includes a plurality of phase legs connected in delta configuration. Each leg includes a plurality of series connected submodules, each submodule including an energy storage. The method includes disconnecting the MMC from an electrical grid, discharging the energy storages by means of a circulating current, and reconnecting the MMC to the electrical grid. The discharging includes, for each phase leg, setting a voltage reference, and sequentially selecting submodules in zero state by means of a sorting algorithm for switching each of the selected submodules to plus or minus state until the voltage deviation from the set voltage reference of the energy storage of each submodule in the phase leg is within a predefined range.

Claim (Index 6):
A Modular Multilevel Converter, MMC, comprising:\n a plurality of phase legs connected in delta configuration, each leg comprising a plurality of series connected submodules, each submodule comprising an energy storage; a circuit breaker for, in a closed position, connecting the MMC to an electrical grid, and for, in an open position, disconnecting the MMC from the electrical grid; and a control arrangement configured for, when the circuit breaker is in the open position, for each phase leg:\n setting a voltage reference; and \n sequentially selecting submodules in zero state by means of a sorting algorithm for switching each of the selected submodules to plus or minus state until the voltage deviation from the set voltage reference of the energy storage of each submodule in the phase leg is within a predefined range.
