Emerson to unify control of boiler and turbine operations for improved unit stability, responsiveness, and thermal efficiencies

PITTSBURGH (July 8, 2010) — Emerson Process Management has been selected to install its Ovation™ expert control system at Rabigh Power Plant units 1 and 2. Owned by Saudi Electricity Company (SEC), this new 1,320-MW (2x660 MW) oil-fired plant will provide electricity to spur economic development in the Western Province of Saudi Arabia. The contract was awarded by SEPCO III, which is the first Chinese company to secure an EPC (Engineer Procure Construct) contract to build a power plant in this Middle Eastern country. 

At each unit, an Ovation control system will perform data acquisition, and monitor and control the boiler, turbine and heat recovery steam generator (HRSG), all supplied by Donfang Electric Corp. Unifying control of boiler and turbine operations contributes to improved unit stability, responsiveness and thermal efficiencies; tighter overall control of plant operations; and a more streamlined view of key plant and turbine parameters.

The Ovation system will also control the modulation control system, sequence control system, furnace safety supervisory system, electric control system, flue gas desulfurization (FGD) system, feedwater pump turbine and balance-of-plant processes. In addition, Ovation technology will manage systems common to units 1 and 2 using multi-networking technology. For additional efficiency, operators will be able to monitor and control operations of both units from a central control room. 

All told, the Ovation control systems will manage approximately 18,700 I/O points. The contract calls for Emerson to supply a total of 44 Ovation redundant controllers (20 per unit, as well as four that will be common to both units) and 22 workstations. Unit 1 is currently slated for startup in July 2012, and Unit 2 in April 2013.

“Emerson has earned a stellar reputation based on its previous involvement in large EPC power projects,” said Wei Yuan, I&C specialist, SEPCO III. “Their prior EPC experience, along with leading-edge technologies and strong engineering and service resources, were the primary reasons we selected Emerson for this project.”  

“This project demonstrates how we are able to leverage our resources to efficiently and effectively meet customer needs anywhere in the world,” said Bob Yeager, president of Emerson’s Power & Water Solutions division. “We’re honored to be selected by SEPCO III for a project that will further economic development in Saudi Arabia.”
