Emerson Process Management has won a contract to automate the new 780MW Wangting combined cycle power plant.

Emerson will install its innovative PlantWeb digital plant architecture at the Wangting plant, which is owned by China Huadian Corporation and located in Suzhou City in China's Jiangsu Province.

The two-unit plant will provide additional power to China's eastern provinces, which are developing faster than the existing power supply.

Emerson is introducing PlantWeb to the China power generation controls market, which is estimated to total $120 million annually, with projected growth of around 15% per year.

Current planning calls for construction of 500 new power units by 2010.

New to the China power market, PlantWeb has proven to deliver significant savings in construction and engineering of new projects, as well as operations efficiency across industries throughout the world.

Emerson's digital automation of the Wangting plant will include deployment of Foundation fieldbus technology that saves design, wiring, termination, and space cost by replacing bundles of individual wires with single wire buses.

The single wire busses carry significantly more information about the process and equipment than traditional systems, enabling efficiencies in operation and maintenance.

Emerson's Power and Water Solutions industry centre will co-ordinate and supervise the project, which represents the company's first Asia-Pacific application of Foundation fieldbus with its Ovation expert control system.

For Emerson customers, PlantWeb is the blueprint for implementing a comprehensive, digital solution that delivers installed cost savings and operations savings.

This automated solution delivers asset management, process control and management execution through intelligent field devices and critical plant assets, standards and scalable platforms, and integrated modular software.

Throughout the plant, control and monitoring of the process is performed by intelligent field devices that deliver predictive diagnostic information to AMS Suite: Intelligent Device Manager software within the Ovation system.

At Wangting, Emerson will install a redundant Fast Ethernet network, eight redundant controllers (four per unit), 10 Ovation workstations (five per unit), Hart intelligent field devices, Rosemount Foundation fieldbus temperature devices, and AMS Suite: Intelligent Device Manager.

In all, the Ovation system will manage over 2400 I/O points and will provide data acquisition and control, including sequence of events, electrical control, main plant control and balance of plant control.

The units are expected to be operational in June 2005.

"We selected Emerson because its proven PlantWeb digital automation approach differentiates the organization from its competitors", said Feng Guo Rong, China Huadian Group.

"We were looking for a control system that would enable the plant to provide clean, efficient energy and comply with future environmental regulations".

"We found that in Emerson".

"We've experienced firsthand in other industries how the early adoption of PlantWeb can dramatically impact construction costs and follow-on operations efficiency", said John Berra, President of Emerson Process Management.

"Emerson is committed to helping the power generation industry adopt this approach".

"This project is significant because it indicates China's growing confidence in bus-enabled technologies like Ovation and PlantWeb".
