New traction sub-station to supply power

Staff Reporter

NEW DELHI: A new Delhi Metro Traction sub-station which will supply power to the underground Metro Corridor — including the seven-km section from the Kashmere Gate to the Central Secretariat that will be inaugurated on July 2 — was commissioned on Tuesday by the Managing Director of the Delhi Metro Rail Corporation, E. Sreedharan. The function was attended by the Managing Director of IRCON, B.S. Kapoor.

This sub-station will feed power to trains and the stations on the 11 km underground section from the Delhi University to the Central Secretariat. The 66/33/25 kV GIS (Gas Insulated Switchgear) sub-station is the first in the country where 66 kV and 25 kV GIS equipment has been used. It has been completed in eight months.

The DMRC said the sub-station is getting 66 kV from the Gas Turbine Power Station (GTPS), Indraprastha, through five-km long cables along the Ring Road and the Jawahar Lal Nehru Marg. The GTPS is a reliable source of power supply and will ensure that even if the Northern Grid fails, Delhi Metro continues to get power. This will reduce the probability of power failure. The underground Metro Station will be lit all the time.

The sub-station will be centrally controlled from the Metro Operational Control Centre at Shastri Park. A fully automatic computerised system called the Supervisory Control and Data Acquisition System will control the supply and can detect faults. The state-of-the-art equipment has been installed by M/s IRCON International Ltd. The Gas Insulated Switchgear System requires only half the space compared to a traditional sub-station and is more reliable, DMRC said. The equipment at the GIS sub-station is placed inside a metallic enclosure filled with Sulphur Floro Oxide Gas.
