India has the world's fifth largest coal reserves and, as an affordable commodity, coal may remain the fuel of choice for a long time to come. Given this backdrop and the need to rapidly add new capacity in the power generation sector to meet the supply-demand gap while complying with environmental regulations, it becomes imperative to adopt technologies that increase fuel efficiency and reduce carbon emissions from coal-fired thermal power plants.
Consequently, supercritical technology assumes significance in India's power sector, both to improve efficiency and adhere to environmental standards. Today's supercritical units can achieve thermal efficiency of more than 45 percent, compared with a typical subcritical plant's 30-35 percent. In a typical power plant, however, major equipment - boiler, tur-bine and generator (BTG) - are controlled with separate control systems supplied by different manufacturers. Even control systems for station control & instrumentation (C&I), electrical, and the balance of plant (BOP) equipment such as coal handling, ash handling, and cooling water systems, are often separate. Each system has its own hardware and software platform, which adversely affects the interface time between control systems and limits operational flexibility.
