The paper describes a simulator study of a four-terminal HVdc system with a small parallel tap and interconnected to an AC network with weak AC systems at the four dc terminals. The small tap is rated at 25% of the rating of the HVdc system and the effective short-circuit ratios at the dc terminals are in the range of 2.1 to 3.0. The study includes the… (More)
