China Power Investment Group has awarded Emerson Process Management a contract to install its Ovation expert control system at two new ultra-supercritical power generating units, each of 1 GW, under construction at the Changshu power plant in Jiangsu Province, China.

The two new units, Unit 5 and Unit 6, at the Changshu plant, which currently has four 300 MW units, are expected to come online in February 2012 and August 2012, respectively.

At each new unit, the Ovation system will monitor and control the Shanghai boiler and balance- of-plant processes, as well as interface to the controls of the Shanghai turbine. The Ovation systems for the two units will manage more than 30,800 I/O points. Emerson will supply a total of 18 workstations and 56 redundant controllers.

“We look forward to working with China Power Investment Group as they enhance the Changshu plant’s capacity, efficiency and environmental performance,” said Bob Yeager, president of Emerson Process Management’s Power & Water Solutions.

“Such large, complex projects offer an ideal opportunity to apply our unique combination of local resources and global power-industry expertise.”

Ultra-supercritical technologies that can make coal fired generation 50 per cent more efficient are becoming more prevalent in China. Emerson claims that its automation and control technologies are installed in nearly two thirds of China’s 1 GW power plants.
