CONTROLLING AN INVERTER DEVICE OF A HIGH VOLTAGE DC SYSTEM FOR SUPPORTING AN AC SYSTEM

摘要

The invention concerns a method of controlling an inverter device, a control device as well as an inverter device and a direct current power transmission system. The direct current power transmission system (10) is provided for connection to an AC voltage bus (13) of an AC power system (14) and comprises the control device (24) and the inverter device (18) that converts between DC power and AC power. The control device (24) receives measurements of the voltage (VAC) at the AC voltage bus (13) and controls the inverter device (18) to provide a constant AC voltage on the bus.
