Nokia has provided Tata Power Delhi Distribution Limited (DDL) with a state-of-the-art Internet protocol/multiprotocol label switching network to support the management of its electrical grid in its area of operation in North and North-West Delhi. This deployment has enabled Tata Power-DDL to support mission-critical operational services as well as traditional business and IT services, all on a single communications network. Tata Power-DDL is the first power utility in India to successfully 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, distribution automation, and much more. 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 business applications, including customer relationship management (CRM), enterprise resource planning, and video surveillance systems.
