Tata Power Delhi Distribution (Tata Power-DDL) has recently commissioned a 66/11 kV AIS grid substation at Dheerpur, Delhi. The newly-commissioned substation will benefit over 56,500 existing and new customers in Dheerpur, Indravihar, Burari, Jahangirpuri, Mukherjee Nagar, Wazirabad Water Works and adjoining areas. The substation will further improve the reliability of power supply and facilitate the load growth in these areas.
The newly commissioned grid substation has an installed capacity of 50 MVA, with 16 outgoing feeders at 11 kV level. It is an unmanned substation and will be remotely operated from Tata Power- DDL’s state-of- the-art supervisory controlled and data acquisition centre (SCADA).
The substation has an incoming supply from four 66 kV composite circuits emanating two Lines from 220KV DTL Gopalpur Grid and two Lines from 66KV TPDDL Jahangirpuri grid. This grid is built on 100 percent pipe foundation and is equipped with two power transformers of 25 MVA capacity each and nitrogen injection fire prevention and extinction system (NIFPES) power transformers along with auto-switched capacitor bank to ensure safe and quality power supply.
Speaking at the inauguration, Mr Sinha said, "The commissioning of the grid substation at Dheerpur (North Delhi area) is a part of our commitment to ensure seamless power supply in our distribution area through N-1 principle which quickly restores supply overcoming contingencies. We are continually making our network future ready so that it can successfully meet the growing electricity demand including any eventuality."
