ABB has won a turnkey Flexible AC Transmission System (FACTS) order, valued at US$17 million, from Powergrid Corporation of India Limited (PGCIL).
ABB will build a fixed and thyristor-controlled series compensation scheme for PGCIL’s 412-kilometer long, 400 kV double-circuit inter-regional tie line.
According to ABB, the line, along with the existing 1000 MW HVDC back-to-back link in Chandrapur, will ensure reliable power supply and stable inter-regional transfer of power from eastern to southern India. In addition, this will reportedly minimise cascade trippings and the chances of a grid collapse, if either pole of the HVDC bipoles were to trip.
The order comprises design, manufacture, equipment supply, erection, testing and commissioning of this FACTS application.
The equipment includes thyristor valves and associated cooling system, the complete control systems, as well as digital optical current transformers.
The project is scheduled to be commissioned in around 15 months.
