Abstract :
The application of HVDC for stabilizing the large interconnected AC networks are resulting in several HVDC links inverting in the close electrical proximity. These multi-infeed HVDC system inverting into a weak AC network are of serious concern. One of the possible solution for better stability is using a VSC-HVDC as one of the infeed for the multi-infeed system. In this paper a multi-infeed HVDC system combining a conventional LCC-HVDC system and a Hybrid HVDC system consisting of LCC as the rectifier and VSC as the inverter is proposed for supplying a very weak AC network. The system performance during steady state and transient conditions is studied by simulation software PSCAD/EMTDC.
