Siemens selected to upgrade India’s oldest HVDC system

India: Power Grid Corporation of India selected Siemens to modernize 30-year-old high voltage direct current (HVDC) system in Madhya Pradesh state of India.

The country’s first and oldest 500 MW HVDC back-to-back link, Vindhyachal, was commissioned in 1989 to interconnect the asynchronous 400 kV alternating current networks of the Northern and Western regions.

Siemens will be responsible for installing latest HVDC components in order to extend the life of the HVDC link and ensure reliable power supply.

Siemens Gas and Power Transmission Solutions head, Mirko Düsel, said: “We look forward to extending the lifespan of the station and enhancing the installation’s efficiency by implementing our state-of-the-art technology.”

Siemens said that contract will be its first HVDC modernization project in India and its first refurbishment of a third-party system involving replacement of the thyristor valves.

Under the contract, Siemens will install new thyristor valves, converter cooling system, HVDC control and protection system, direct current measuring devices and surge arrestors.

The firm plans to deliver the key components for the upgrade including the thyristor valves as well as the HVDC control and protection system, from its facility in Goa, India.
