Title: Control arrangement and method for regulating the output voltage of a dc source power converter connected to a multi-source dc system
Inventor: HU LIHUA
IPC: H02M3/158
Filed: 2012-02-07
Abstract: A converter control arrangement (18, 48) for regulating the output voltage of a dc source power converter (16) connecting an ac system (6) to a HVDC system to enable dc electrical power to be supplied from the ac system (6) to the HVDC system comprises a dynamic droop control device (26) including first and second droop controllers (30, 32) in which the droop rate of the second droop controller (32) is greater than the droop rate of the first droop controller (30). The converter control arrangement (18, 48) comprises a voltage regulator (20) for regulating the output voltage of the dc source power converter (16) by comparing an output voltage value (Vout) with a target voltage value (Vtgt) derived by combining a reference voltage value (Vref; V''ref) and a droop voltage value (Vdr) provided by the dynamic droop control device (26). The first droop controller (30) controls the droop voltage value (Vdr) when an output current value (Iout) of the dc source power converter (16) is less than a reference current value (Iref). The second droop controller (32) controls the droop voltage value (Vdr) when the output current value (Iout) is greater than the reference current value (Iref). The reference current value (Iref) is the desired output current value (Iout) of the dc source power converter (16) and defines, in combination with the reference voltage value (Vref; V''ref), a target operating point (36).
