Emerson controls for new Saudi power plant
8 Jul 2010
Pittsburgh, Pennsylvania – Emerson Process Management is to install its Ovation expert control system at Saudi Electricity Co.’s new 1,320-MW (2x660 MW) oil-fired Rabigh Power Plant. The contract was awarded by SEPCO III, which is the first Chinese company to secure an EPC contract to build a power plant in Saudi Arabia.
At each unit, the control system will perform data acquisition, and monitor and control the boiler, turbine and heat recovery steam generator, all supplied by Donfang Electric Corp.
The unified control of boiler and turbine operations will improve unit stability, responsiveness and thermal efficiencies, according to Emerson. It will also, it said, tighter overall control of plant operations; and a more streamlined view of key plant and turbine parameters.
The Emerson 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, the Emerson 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. The control systems will together manage around 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.
