Emerson Wins Contract for Automation of Basin Electric Power Cooperative’s New Dry Fork Station

PlantWeb® digital plant architecture with Ovation® control system to use digital bus-based communications, SmartProcess® optimization technology, and Scenario® high-fidelity simulator

PITTSBURGH, PA (Jan.14, 2009) — Emerson Process Management announced today it has received a contract from Basin Electric Power Cooperative to digitally automate Dry Fork Station. This new, 385-MW coal-fired power plant is being built to meet the growing electricity demand of the cooperative members. Dry Fork, located in the Gillette, Wyo., area, is expected to be operational by 2011.

Emerson’s comprehensive PlantWeb® solution includes deployment of the Ovation® expert control system, which will monitor and control the plant’s main and auxiliary boilers, as well as the burner management system, air quality control system, and balance of plant processes. The Ovation system will also perform data acquisition, including sequence of events. The new plant will make extensive use of digital bus-based technologies, with Emerson’s Ovation system incorporating 230 Foundation™ fieldbus segments (representing 1,100 devices) and 106 Profibus segments (representing 1,000 Profibus-DP devices). In total, the Ovation system will manage more than 4,600 hard I/O points.

In addition, Emerson will provide AMS® Suite predictive maintenance software which streamlines device configuration and commissioning. AMS Device Manager also provides online access to instrument and valve diagnostics and automatic documentation of all field device maintenance information – all contributing to ongoing efficiency of plant operations and maintenance activities.

Dry Fork will also utilize Emerson’s SmartProcess® combustion optimization technology. By incorporating fuzzy logic, advanced analytics and model predictive control, SmartProcess optimization technology offers adaptive improvement solutions to help utilities achieve optimized equipment performance for emissions compliance, temperature control, efficiency, and overall continuous operational improvement.  

As part of its comprehensive automation and control solution, Emerson will also supply a high-fidelity Scenario® simulator. Configured using control logic identical to that of the plant, high-fidelity simulators offer a highly realistic training and engineering analysis environment. In addition to training Dry Fork operators on the new Ovation system, Emerson’s simulation solution will be used to test and verify control logic and for unit check-out prior to the plant’s synchronization to the grid.

"We’re gratified to have once again earned the trust of Basin Electric,” said Bob Yeager, president of the Power & Water Solutions division of Emerson. “We’re particularly pleased to be able to provide a complete automation and control solution that encompasses not only our Ovation control system, but also the latest predictive maintenance, simulation, optimization and digital bus technologies. By seamlessly integrating these complementary solutions, Basin Electric can expect Dry Fork to achieve smoother commissioning and startup, as well as greater plant availability, reliability and performance over the long term.”
