In Tokaido Shinkansen, the power of a feeding substation increases in a short time because the train schedule is of high density and the acceleration performance of the rolling stock has improved. If the load power of the feeding substation increases further, the feeder voltage cannot be maintained when the power converter supplies only the reactive power. Because such a case was assumed in the frequency conversion section, we developed the Electronic Frequency Converter controls the A. C. voltage using the fixed power factor method. The Electronic Frequency Converter is under construction in the Numazu frequency conversion substation. We describe the domination of A. C. voltage control using the fixed power factor method.
