Abstract

The Kii Channel HVDC Link with capacity of 1400 MW at DC+/-250 kV was commissioned on June 22, 2000. This is one of the largest HVDC links in the world. New technologies, such as high-voltage large-capacity light-triggered thyristors, DC gas-insulated switchgear, new HVDC control method and so on, had been newly developed in order to reduce construction costs and installation space for equipment and also improve system reliability. HVDC system performance tests were carried out under the condition of connecting with commercial AC power system from January to June 2000. In these system tests, fundamental operation functions, PM (power modulation) function, EFC (emergency frequency control) function and so on, were confirmed. The Kii Channel HVDC Link has been operating stably and satisfactorily since its commissioning.
