India commissions first VSC HVDC link improving power quality , 4 days ago The JV of Sumitomo Electric and Siemens Energy has completed connecting India’s first high-voltage direct current (HVDC) link featuring voltage-sourced converter (VSC) and DC-XLPE cable technology.
The 2,000-megawatts (MW) electricity transmission system consisting of two links which consists of DC-XLPE cable and overhead transmission line between Pugalur in the southern state of Tamil Nadu to Trichur in Kerala State in South-West India supports transmission operator Power Grid Corporation of India (PGCIL) to counter power deficit in India’s southern region and improve the grid stability.
Siemens Energy supplied the two converter stations for the ±320 kilovolt (kV) HVDC system while Sumitomo Electric was responsible for the XLPE HVDC cable system in the DC circuit.
