Abstract
The present invention discloses a Bipolar VSC-HVDC and UPFC Hybrid Topology and its operation method. The first control circuit includes a positive and a negative circuit at the series side, in which the VSC converter can operate in bipolar mode; the second control circuit includes a positive and a negative circuit, in which the VSC converter can operate in bipolar mode; the third control circuit is the same as the second control circuit in terms of structure; the positive electrode and negative electrode of the second control circuit are connected to the DC bus via a DC breaker respectively; the other end of the DC transmission line is connected to the third control circuit via a DC breaker. In addition, the hybrid topology of the present invention can perform multiple operation methods and fast conversions, including the VSC-HVDC and UPFC hybrid operation, UPFC operation, VSC-HVDC operation and generalized UPFC operation, featuring long distance power transmission for high power in VSC-HVDC mode and distribution control of AC power flow in UPFC mode. As a result, the flexibility and availability of system operation can be improved.
