PlantWeb Architecture Coming To Brazil Power Plant
Emerson Process Management is installing its PlantWeb digital plant architecture with Ovation expert control system at the Usina Termelétrica Luis Carlos Prestes power plant in Brazil.
Owned and operated by Petróleo Brasileiro S.A. (Petrobras), the plant is located in Três Lagoas, about 644 km northwest of São Paulo. The Ovation system will help improve the overall efficiency and reliability of the plant, which is being expanded to increase generation capacity, Emerson said.
The plant began operation in 2003 as a 240 MW, simple-cycle power plant using an Alstom generator and four GE 6FA turbines fired by gas from the nearby GASBOL pipeline. To boost productivity and efficiency, the plant is being converted into a 2x2x1 combined-cycle facility. Emerson’s Ovation system will monitor and control four new CBC Heat Recovery Steam Generators (HRSGs) that will feed two new Siemens steam turbines. The steam turbines will generate an extra 128 MW of electricity – using the same amount of fuel – helping Petrobras meet the area’s growing demand for power.
As part of the contract, Emerson is also upgrading all existing Ovation controllers and adding its AMS Suite predictive maintenance software. The Ovation system will interface to other systems via Modbus RTU over Ethernet, PROFIBUS DP, and OPC communications protocols. In all, the Ovation system will manage 10 500 I/O points. Emerson will also provide training and field services for plant startup and commissioning. The plant is expected to be in full production in July 2011.
