Abstract:
The present invention discloses a novel Unified Power Flow Controller UPFC and its control method. Supposing that one end of DC converter is connected to the DC transmission line of HVDC converter station or substation and the other end is connected to the DC side of a series converter, the AC output voltage of the series converter can be controlled to regulate the line power of the UPFC for operation in UPFC and SSSC mode. In addition, when the number of transformers and shunt converters is decreased at the shunt side of the UPFC, the HVDC Converter Station can be used to provide active power for the series converter of UPFC, which can effectively reduce operation costs and ensure stable operation of power grid. Therefore, there is a bright application prospect for the invention.
