SDG&E Talega STATCOM project-system analysis, design, and configuration

San Diego Gas & Electric (SDG&E) initiated a major transmission system enhancement project involving a key 230/138 kV substation and the installation of a STATCOM-based dynamic reactive compensation system. This project is currently scheduled by SDG&E for an in-service date in October 2002. This paper gives an overview of the SDG&E transmission system project with emphasis on the STATCOM-based dynamic reactive compensation system. The major items with respect to the STATCOM system addressed in this paper include: power system requirements; STATCOM system description; STATCOM system layout; STATCOM construction and installation.
