Gas Insulated Substations are essential in the transmission and distribution of electrical energy at growing urban cities. To meet this growing demand, DLF has set up its own electric substation at DLF5. We give you a report.
When conventional air insulated substations fail to meet the requirements of the available space, pollution, safety and maintenance in an urban city, one needs to upgrade it to the next best technology which, in this case were Gas Insulated Substations (GIS).
Since DLF has always been ahead of its time, it recently unveiled a substation at DLF5, a first ever to be set up by a private developer in Haryana. Spread over 1.25 acres, the substation has a capacity of 60MVA with three 16/20 MVA, 66/11 kV transformers and SCADA system for monitoring and controlling 66kV GIS equipment. So it’s no surprise that condominiums at DLF5 now enjoy a 24×7 power supply.
To say it simply, DLF5 was earlier getting power from the substations at sectors 43 and 52. But they were already overloaded. Even the feeders with multiple connections often gave way; power cuts before ESS sometimes went up to 4 hours. But now with the new substation that is safe, compact and low-maintenance, things have really settled down. The new state-of-the-art gas insulated substation has the following advantages
1. ESS isn’t overloaded
2. Electricity breakdowns have come down to almost nil.
3. 3 X 20 MVA=60MVA is its present capacity with space to enhance the capacity up to 75 MVA.
4. SCADA system for real time load monitoring and control.
5. Dedicated 11 kV feeders through underground cables to all condominiums for better safety, control and minimum shutdown time.
6. Two sources of power to DLF GIS, one from sector-52 S/S and the other from sector-56 S/S through underground 66kV cables.
7. Staff quarter for GIS staff for ensuring minimum response time in case of breakdown.
8. Suitable 11kV capacitor banks to maintain the voltage level
