Tata Power Delhi Distribution limited (TPDDl) and Nokia on Thursday join hands to modernise electrical grids with advanced communications networks. Nokia will equip the TPDDl with an ‘Internet Protocol/MultiProtocol’ (IP/MPlS) label switching network to support the management of its electrical grid in its operations in North and North-West Delhi.
With this deployment, TPDDl has become the first power utility in India to successfully implement teleprotection service using line-differntial relay (lDR) over an IP/MPlS network.
Praveer Sinha, CEO & MD of TPDDl said: “We are happy to join hands with Nokia for modernising electrical grids with advanced communication networks. 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.”
Sanjay Malik, head of India Market, Nokia, said: “Our leadership in the development of utility-specific features for IP/MPlS networks has enabled us to deliver a resilient, secure and highly efficient network for TPDDl that will serve as an ideal foundation for smart grid applications in the future.”
TPDDl is the first power utility in India to successfully implement teleprotection service using 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 localised region.
“Through the new IP/MPlS network, TPDDl is able to support virtually all of its operational and business services on a single network, providing enormous efficiencies. Since privatisation, the “Aggregate Technical & Commercial” (AT and C) losses in TPDDl areas have shown a record decline. Today, AT and C losses stand at 8.88% which is an unprecedented reduction of around 82% from an opening loss level of 53% in July 2002,” said a TPDDl official.
“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 localised region. This also enabled TPDDl to support missions such as critical operational services as well as traditional business and IT services all on a single communications network,”he said.
