Özet:

 

The integration of a capacitor-commutated converter (CCC)  high-voltage direct current (HVDC) (CCC-HVDC) and voltage source converter  (VSC) HVDC (VSC-HVDC) is proposed in this paper to supply entirely passive  AC networks. The key point of this integration is the flat characteristic of  the DC voltage of the CCC-HVDC, which provides the condition for the VSC to  connect to the CCC DC link via a current regulator. The advantages of the  proposed combined infeeding system are the requirement of only one DC line,  and better dynamic responses. The structure of the proposed infeeding  system, as well as its control system, is studied. Simulation results are  provided to validate the effectiveness of the proposed system and its  control strategy. Two other schemes for infeeding AC passive networks are  studied to demonstrate the advantages of the proposed system.
