Sheila Dikshit inaugurates state-of-the-art SCADA centre at Balaji Estate in Kalkaji

NEW DELHI: Chief Minister Sheila Dikshit on Friday inaugurated a state-of-the-art Supervisory Control And Data Acquisition (SCADA) system of BSES which is expected to reduce fault restoration time by over 60 per cent.

Speaking at the inauguration of SCADA centre at Balaji Estate in Kalkaji, Ms. Dikshit expressed happiness that installation of the system has brought Delhi in the league of global cities like Singapore, Hong Kong and Stockholm and strengthened its claim of becoming a truly world-class city. "I sincerely hope that SCADA will bring about visible improvements in power distribution and reduce the incidence of outages. We are all committed to ensuring that Delhi tops the list of great cities by providing unparallel public services to its residents,'' she said.

BSES said the SCADA System -- which would cost around Rs.153 crore -- would change the face of power distribution in its licensed area and benefit all its 23 lakh customers. The SCADA System Centre will monitor the power distribution system and supply on a real time basis and abnormalities in the system will be immediately flagged and corrective action taken.

Operations of all 117 grid stations in the BSES area would now be remote-controlled through the SCADA control centre.

While 60 grid stations are already online, the remaining will also come into the SCADA fold over the next few months. The first phase of SCADA will cover all the 66/33 kV Grid Stations and the second phase will cover the 11 kV Distribution Network comprising transformers, feeders and lines.

Stating that "the communication between the Grid Station and Control Centre is being established and optic fibre network with ring loop formation will ensure online connectivity at all times,'' a BSES official said when fully implemented, SCADA would lead to faster identification-isolation-and restoration of faults, loss minimisation, forecasting of load, intelligent alarms, better resource handling, reactive power management, Distribution Management System (DMS), more efficient outage management, switching optimisation and network study and planning.

Also on complete implementation, SCADA will drastically reduce the total fault restoration time from an average of 110 minutes at present to less than 45 minutes.

BSES Rajdhani Power Limited CEO Lalit Jalan said SCADA was a giant leap in the efforts to automate the total process of electricity management and when fully implemented, it would lead to a quantum leap in operational efficiencies.

BSES Yamuna Power Limited CEO Arun Kanchan said: "The integrated outage management system, running over Geographical Information System (GIS) will help identify affected areas on geographical map and facilitate the maintenance crew with route maps, network details for a faster response time.''

BSES also announced adoption of international disaster management practices to ensure that its customers continued to get uninterrupted power supply even in the wake of unforeseeable disasters and calamities. It said a Master Control Centre (MCC) and a Backup Control Centre (BCC) had been planned with a Fibre Optical Communication Network that would ensure that both remain connected, synchronised and updated in real time.
