Control system installed for power generating units

The Changshu power plant in Jiangsu Province, is expanding its power generating units and is using Emerson's Ovation expert control system for automation


Emerson Process Management is installing its Ovation expert control system at the Changshu power plant in China. Courtesy: EmersonThe 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 under construction at the Changshu power plant in Jiangsu Province, China. Ultra-supercritical technologies are becoming more prevalent in China because they can boost the efficiency of coal-based electricity generation by approximately 50 percent, while maintaining superior environmental performance. Emerson’s technology will help China Power run the new units safely and efficiently.

Expansion of the existing 4 X 300-MW Changshu plant will support economic development of China’s Yangtze Delta area. The two new units, Unit 5 and Unit 6, 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.
