  • Controlling an inverter device of a high voltage DC system for supporting an AC system
    Patent number: 8830712
    Abstract: A method of controlling an inverter device, a control device, an inverter device and a direct current power transmission system are provided. The direct current power transmission system is provided for connection to an AC voltage bus of an AC power system and includes the control device and the inverter device that converts between DC power and AC power. The control device receives measurements of the voltage (VAC) at the AC voltage bus and controls the inverter device to provide a constant AC voltage on the bus.
