Abstract

This paper presents an original analytical model for the direct connection of a HVDC converter to a synchronous generator, without AC filters and AC bus, usually referred to as Unit Connection. All the operation modes and its transition regions are precisely determined, which simplifies the usual analysis of this arrangement. Digital simulations of an equivalent traditional model, based on an electromagnetic transient program for DCAC systems, were used to validate the results.

José Daldegan Jr, ELETRONORTE - Brazilian Holding Electric Power Co., Caixa Postal 04163, CEP 70.718-900 - Brasília – Brazil

was born in Brasília, Brazil, in 1962. Received his B.Sc. in Electrical Engineering in 1984 from the University of Brasília; received his M.Sc. and D.Sc. in Electrical Eng. from the Federal University of Rio de Janeiro, in 1992 and 1999 respectively, both related to Power Electronics Applied to Power Systems. From 1985 to 1988 he worked at a consulting company of power systems. Since 1989 he works on the Eletronorte – a Brazilian Holding Electric Power Co., studying the transmission systems in the north of the Brazil. Dr. Daldegan was member of the CIGRÉ Joint Working Group 11/14-09 which systematized a guide for preliminary design and specification of hydro stations with HVDC unit connected generators.
