Nokia Supplies Mission-Critical Network to Indian Utility
Thursday, March 09, 2017 | Comments

Nokia provided Indian power utility Tata Power Delhi Distribution (Tata Power-DDL) with an IP/multiprotocol label switching (IP/MPLS) network to support the management of its electrical grid in its area of operation in north and northwest Delhi. The deployment enables the utility to support both mission-critical operational services, as well as traditional business and IT services on a single communications network.

Tata Power-DDL is the first power utility in India to implement teleprotection service using line-differential relay (LDR) over an IP/MPLS network. This is an essential requirement for operating and maintaining a reliable, robust and safe electric grid. Teleprotection makes it possible to detect the presence of faults and trip breakers to isolate a certain section of the grid, containing the impact of the fault to a localized region.

Other mission-critical operational services supported by this network include supervisory control and data acquisition (SCADA), integrated surveillance system, distribution management system and distribution automation. The network is also enabling Tata Power-DDL to support emerging smart grid applications such as distributed energy resources, mobile workforce management systems and automated demand response. The network also delivers traditional video surveillance systems.

On top of its IP/MPLS network equipment, Nokia provided professional services including network design, installation, commissioning and integration. Nokia will also provide maintenance services and support.

"We are happy to join hands with Nokia for modernizing electrical grids with advanced communications networks,” said Praveer Sinha, CEO and managing director of Tata Power-DDL. “The IP/MPLS network provided by Nokia will not only aid in speedier smart grid implementation but will also help in improving the reliability, scalability, security and efficiency of the power network through real-time monitoring, which will benefit our customers."
