Emerson to install control system at KCP&L’s Iatan Units 1 and 2

7 December 2006 — Emerson Process Management announced that it has won two contracts from Kansas City Power & Light (KCP&L) to install its PlantWeb digital plant architecture with the Ovation expert control system at Iatan Units 1 and 2 in Platte County, Mo. KCP&L, with headquarters in Kansas City, Mo., serves about 500,000 customers in 24 western Missouri and eastern Kansas counties.

Under the first contract, Emerson will digitally automate Iatan Unit 2, a new 850-MW, coal-fired unit that is being built as part of KCP&L’s comprehensive energy plan to meet the future needs of the Kansas City area. This unit is classified as a supercritical plant, meaning it will use new clean coal technology enabling operation at elevated steam temperature and pressure for increased efficiency and reduced fuel-related emissions. This facility, to be co-owned by Aquila Inc., The Empire District Electric Company, Kansas Electric Power Cooperative, Inc. and the Missouri Joint Municipal Electric Utility Commission, is scheduled to go into service in 2010.

Emerson’s PlantWeb digital plant architecture utilizes high-speed communications networks, intelligent field devices, asset management software and bus I/O technologies to help power producers control critical plant processes, increase plant efficiencies and megawatt production, and realize long-term operations and maintenance savings.

The Ovation control system will monitor and control the unit’s supercritical boiler, as well as the burner management system, motors, sootblower and balance of plant processes. The Ovation system will also interface to the unit’s turbine and control the Air Quality Control System (AQCS) for the unit’s flue gas desulphurization (FGD) system.

Under the second contract, Emerson’s Ovation system will also control the AQCS for the new FGD system that is being added as part of a pollution control upgrade project for Iatan Unit 1.

Both projects include extensive use of digital bus-based technologies for networking intelligent field devices: The Unit 1 AQCS project includes 22 Foundation fieldbus segments and 12 PROFIBUS DP segments, while Unit 2 incorporates 102 Foundation fieldbus segments and 50 PROFIBUS DP segments.

Furthermore, Emerson’s PlantWeb digital automation solution for Iatan Units 1 and 2 includes AMS Suite: Intelligent Device Manager, which streamlines device configuration, enabling savings and increased startup efficiency. AMS Device Manager also provides online access to instrument and valve process information, predictive diagnostic information, and automatic documentation of field device maintenance information — all contributing to ongoing efficiency of plant operations and maintenance activities.
