Abstract

The design of directly light-triggered, water-cooled thyristor valve was designed and manufactured as an extension for the Shin-Shinano frequency converter station (back-to-back system, 300 MW, 125 kV-2400 A) of Tokyo Electric Power Co. is described. The light-triggered thyristor, triggering LED and light guides, gating system, cooling, and structural design are covered. Various tests conducted in the factory and a seismic test on a full-scale valve model are reported
