A consortium of Siemens and Sumitomo Electric Industries has bagged an order from Power Grid Corporation of India (PGCIL) to supply a high voltage direct current (HVDC) transmission system. The total size of the order won by the consortium is $520 million, of which the share of Siemens is around Rs 1,682 crore.
Siemens will be supplying two converter stations with two parallel converters, each rated 1000 Megawatts (MW), using its VSC HVDC technology, while Sumitomo Electric will be responsible for XLPE HVDC cables in the DC circuit. The grid connection is scheduled to go into operation in the first half of 2020.
The Pugalur-Thrissur ±320 kilovolt (kV) HVDC system will connect Pugalur in the southern state of Tamil Nadu to Thrissur in Kerala State in South-West India. The about 200-kilometer-long HVDC connection will be India’s first direct current link using voltage sourced converter (VSC) technology.
The Siemens scope of supply for the turnkey project encompasses design, engineering, supply, installation as well as commissioning and major equipment supplies of the complete HVDC stations, including converter valves, transformers, cooling systems and control and protection technology.
