SOUTH CENTRAL RAILWAY

TRACTION DISTRUBUTION ORGANISATION

OF GUNTAKAL DIVISION

INTRODUCTION:


First Electrification work in Guntakal Division was taken up between GDR-TPTY via Renigunta Railway junction in the year 1984. Renigunta is a gateway to world famous pilgrim centre of Lord Sri. Venkateswaraswamy of Tirumala. Renigunta is connecting Railway link to Tirupati, Katpadi & Kanyakumari in the one direction, Chennai in the second direction, Guntakal & Mumbai in the third direction & Gudur, Vijayawada, Kolkata & New Delhi in the fourth direction. GDR- RU- TPTY section is one that connects Vijayawada Division with Guntakal Division and forms a bypass line for South bound trains from north, and eastern parts of the country.


Profile Details:


      In the year 1984 GDR- RU - TPTY section about 150 TKM (Single line) was electrified making Guntakal Division to occupy a place in the Electrification map of Indian Railways.


Subsequently the Electrification is rapidly expanding in the Division as follows:

Organization:


  • The Organization is headed by Sr. DEE, and assisted by Divisional Officer at Guntakal and Sub Divisional officers at Renigunta, Kadapa, Gooty and Raichur. The division consists of 15 Over Head Maintenance (OHE) and Power System Installations (PSI) depots and 16 sub-stations. The OHE depots carry-out preventive maintenance of the traction installations i.e. the wires over the track from which the Locomotive panto graph draws the current. The PSI depots maintain the Railway traction sub-stations which feed the OHE with 25 KV A.C. Power.
  • The PSI and OHE activities are monitored by the Traction Power Controller (TPC), who monitors the voltages of the system and advises the Section Traffic Controller to regulate trains when there is bunching of trains leading to low voltage and stalling of trains.
  • The equipment at traction sub-stations and switching stations is controlled remotely by TPC.

We Perform:

  • The activities of this department are maintenance of Traction power supply installations, Over Head Equipment, SCADA, construction activities pertaining to the section, and monitoring of energy conservation in electric traction.
  • The Power to OHE required for hauling of electric locos is fed from the 16 Traction sub-stations maintained by Railways, with state-of-the-art protective equipment. A 100% standby Power supply arrangement is designed for feeding un-interrupted power to traction. Railways takes supply from Supply authorities i.e. APTRANSCO/TSTRANSCO/GESCOM at 220/132/110kV for more reliability. The 220/132/110 kV is stepped down to 25kV and fed to the Locos via the Overhead Equipment.

Ø  The electrification of single line section between GTL-DHNE, GY-PDL & DHNE-PNM on 31.03.2017, 30.05.2017 & 04.10.17 respectively.

Ø  Doubling and Electrification works under progress in GTL-NDL section in this DHNE-PDL doubling with electrification completed on 09.03.2020.

 

      Infrastructure was created for maintaining this mighty electrified section at various stations with latest facilities to maintain reliability & tackle break downs at shortest time. Equipments at Railway Traction Substations are being controlled remotely from Remote Control Centre at Guntakal. Status of equipment and parameters at all Remote terminal units will be monitored from Remote Control Centre. Electric Loco shed is being constructed at Guntakal to cater Electric engines to coaching and passenger trains. Un-interrupted power supply to run trains is taken at 132 kV/220kV high voltage supply from DISCOMs at various stations.

 

      Self-propelled OHE inspection Cars and Road vehicles are equipped at various maintenance depots all along electrified route of Guntakal Division. Electrification work is being executed by M/s RE i.e. DMM-PAK & YA-NDL sections shortly to cover 100% of route kilometers of Guntakal Division.

 

      The monthly average electrical consumption towards Electrical Traction is 22.95million units, billing to 15.17 Crore (approx.).

 

Tariff: With effect from April 2020, Traction Tariff per unit (two part tariff) has been changed from 3.75 per kVAh to 5.50 per kVAh & 350 per kVA for all TSS of APSPDCL

Senior Divisional Electrical Engineer – Traction of Guntakal Divisional is the overall in-charge of the Traction Distribution and Traction Operations.  He is  responsible for all technical and organizational matters connected with the efficient maintenance and operation of the power supply installations, Over Head Equipment, Remote control center in the traction distribution, Electrical train operations in the division.
