Siemens Energy and Sumitomo Electric commission first VSC HVDC link improving power quality in India

“Thanks to the excellent cooperation between PGCIL, Siemens Energy and Sumitomo Electric, we are now able to proudly commission the first HVDC link in India featuring VSC technology. The result of this fruitful collaboration will significantly help achieving grid programs like the ‘24x7 power for all’ initiative by India’s Ministry of Power to meet the country’s growing power demand,“ said Beatrix Natter, Executive Vice President Transmission at Siemens Energy.
“We are pleased to announce the successful delivery of the first HVDC-XLPE cable project in India. This was achieved through strong support from PGCIL and collaboration between Sumitomo Electric and Siemens Energy at various levels, even during difficult circumstances caused by COVID-19. With the successful completion of this unique hybrid system, consisting of HVDC-XLPE cable and overhead lines, we proved our reliable technology and project execution. I hope this will be a basis for continuous collaboration with PGCIL and a significant contribution to transmission systems in India,” said Masaki Shirayama, Managing Director at Sumitomo Electric.
Siemens Energy is responsible for design, engineering, supply, installation, and commissioning of the HVDC stations, including converter valves, transformers, cooling systems as well as control and protection technology, plus a complete transition station, while Sumitomo Electric provides design, engineering, supply and installation of the HVDC cable system including civil and installation works. In comparison to conventional HVDC systems, the VSC-based HVDC PLUS technology featured at the Pugalur-Trichur link comes with benefits like additional control features, black start capability, and other functions that will improve the performance and security of the transmission system. The converter stations are linked via a 108km XLPE HVDC cable system comprising four cables a route of 27 km each which was supplied by Sumitomo Electric, and overhead transmission line a route of approximately 155 km installed under another contract.
In February Shri Narendra Modi, Prime Minister of India, officially inaugurated the link that now have been put into commercial operation and enables the exchange of electricity in both directions. HVDC links offer operators more ways, boosting stability and increasing the grid’s power quality, efficiency, and security of supply – urgently needed options as the role of renewable energy grows. In India, where 175 gigawatts of renewable energy-based installed capacity by 2022 is targeted, the HVDC link between Pugalur and Trichur will help meet future requirements and facilitate the efficient use of renewable energy. To date Siemens Energy has implemented more than 57 HVDC projects worldwide and is involved in eleven projects that are currently under construction. Sumitomo Electric Industries has installed nine HVDC cable projects worldwide and works on two ongoing projects including one of the first DC525kV XLPE cable project in Germany.
