SHORT-CIRCUIT CURRENT BASED ON RECTIFIER CIRCUIT AT DC. SUBSTATION

On D.C. electrical railways in urban commuter service sections, an increase in electric load on equipments is so remarkable that in case of a short-circuit fault in the feeder circuit the short-circuit current reaches tremendous magnitude. So far, the exact calculation method for it hasn't been established. Tried was calculation of transient impedance of D.C. feeder circuit consisting of many lines as well as rails, and demonstrated that this can be calculated by treating it as transient phenomena of polyphase rectifying circuits with such impedance on D.C. side. Also proposed is a simplified calculating method that proved the sufficient practical equivalency of the method.
