Abstract
AbstractThe authors have proposed FRIENDS as a concept of the future electric power system. In order to realize FRIENDS, it is necessary to design the concrete interior structure and control scheme of the Quality Control Center (QCC) which is to be installed between distribution substation and customers. Hybrid‐type transfer switches are assumed to be installed on the high‐voltage side of the QCC to realize network reconfiguration. Some devices for handling power quality are also assumed to be installed on the low‐voltage side to realize customized power quality.In this paper, a novel control scheme for shutoff of the thyristor switches by the power quality handling devices is proposed and the effectiveness of the proposed scheme is investigated through momentary analysis using PSCAD/EMTDC. © 2002 Wiley Periodicals, Inc.
