“…In [13] SPV integration in African Railways yet describe DC to Dc interface as seen in paper [14] Power quality issues due to tiny capacity posing problems of synchronous inertia i.e rate of change of frequency [15]. Hybrid topology as discussed in [16] again rests with DC-to-DC interface. High speed multiple units [17] applications provide solutions to load side but not the source side from green power interception.…”

Indian Railways has planned to tap 1000 MW solar energy in ensuing five years.500 MW from railway platform roof tops & rest from other official ancillary complexes to supplement traction load. Roof-Top spaces are ample considering long & wide railway platform at stations in India. TSS in railway traction power supply is placed for each 50 to 90 km segment along railway track for UP & DOWN routes. It is possible to design suitable scheme that can be interfaced for direct connection to 25 kV AC system at TSS locations on 4 to 5 average railway platforms from Bhusawal via Jalgaon, Pachora Nandgaon, Manmad, Lasalgaon, Niphad, Nashik Road ,Igatpuri & Kasara Stations. Considering roof top area of 1000 to 5000 sq-metre, it is possible to install solar panels which can generate 100 kW to 500 kW. Saving with conventional Energy intake from utility to the tune of 30 to 40 %. It has been physically seen on live train passing that the load varies from few hundred kW to 3 or 4 MW for duration of few seconds to minutes. Neutral sections facilitate balanced loading on all three phases of utility as the phases R, Y & B are loaded in sequence. This paper explores the ever-tried model of direct solar power feed from railway platform rooftops to 25 kV AC traction supply using dynamic inter-phase power flow technique in real time with all associated balance of equipment’s.
