A study of ±500 kV, 2400 MW compact converter station

Consolidated Edison has been involved in a number of research projects aimed at the development and demonstration of HVDC equipment for use in urban environments. The most notable of these projects has been the installation, in conjunction with EPRI, of a compact HVDC station in Astoria, New York. The Astoria experiment was recently concluded. Here , the authors describe how, as part of Consolidated Edison´s ongoing program to assure the availability of transmission equipment to meet its possible future needs, work was carried out in 1989 to develop a conceptual design of this 2400 MW HVDC compact terminal station based on available equipment suitable for installation in New York City. The study also identified areas where additional research could reduce the cost or space requirements of the installation
