Changes in Electric Power System Technology at Kyushu EPCO

摘要

This paper describes how Kyushu EPCO (Electric Power Co.) has strategically developed over time cutting-edge technologies for its power system in line with the geographical characteristics and social environment of the Kyushu area. Focus is placed on three remarkable accomplishments: technological development to structure an efficient power transmission system taking into account the unique locations of power generating facilities and power demand; measures to improve power system stability in Kyushu, which is located at the terminal end of the west Japan 60Hz power system; and technical solutions to interconnect a long-distance cable between Kyushu's main island and remote islands.
