Abstract

Since we can expect the regenerative coefficient to be lowered by invalidation on particular sections or time zones, we must investigate DC feeding systems capable of increasing the regeneration coefficient. On the other hand, thyristor rectifier substations are being built to replace obsolete silicon rectifier substations. We can control the feeding voltage of substations. In the case of inverter cars such as type 209, the author studied the quantitative effect of energy savings with a feeding voltage control system and demonstrated through simulation an increase in regenerative power and a decrease in power consumption without reducing the acceleration capability of cars. Key words: feeding systems, power electronics, inverter cars 1. Introduction A series of various regeneration car
