Emerson has won contracts from Kansas City Power and Light to install PlantWeb digital plant architecture with the Ovation expert control system at Iatan Units 1 and 2, using new clean coal technology
Emerson Process Management has won two contracts from Kansas City Power and Light (KCPL) to install its PlantWeb digital plant architecture with the Ovation expert control system at Iatan Units 1 and 2 KCPL, with headquarters in Kansas City, serves about 500,000 customers in 24 western Missouri and eastern Kansas counties - a territory of approximately 4,600 square miles

Automating largest drinking water filtration plant
Emerson has won a USD5.3M contract to digitally automate Canada's largest drinking water filtration plant, which will use UV disinfection and geoexchange processes to supply 2M residents
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 the KCPL comprehensive energy plan to meet the future energy, environmental and economic 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, the Empire District Electric Company, Kansas Electric Power Cooperative and the Missouri Joint Municipal Electric Utility Commission, is scheduled to go into service in 2010.

Automation of Vietnam coal-fired power plant
Emerson Process Management has received a contract to install its PlantWeb digital plant architecture with the Ovation expert control system in Units 1 and 2 of the new Vietnam Haiphong Power Plant
Emerson PlantWeb digital plant architecture utilises 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 operational and maintenance savings.
For new plants, PlantWeb offers additional advantages to power generators: by lowering wiring costs, and streamlining device installation, communications verification and troubleshooting.
This digital bus-based approach translates into faster start-up, and reduced start-up and commissioning costs.
The Ovation control system, a key technology that powers PlantWeb, will monitor and control the supercritical boiler, as well as the burner management system, motors, sootblower and balance of plant processes.
The Ovation system will also interface to the turbine and control the Air Quality Control System (AQCS) for the flue gas desulphurisation (FGD) system.
Under the second contract, the Emerson 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, the Emerson PlantWeb digital automation for Iatan Units 1 and 2 includes AMS Suite: Intelligent Device Manager, which streamlines device configuration, enabling savings and increased start-up efficiency.
AMS Device Manager also provides on-line access to instrument and valve process information, predictive diagnostic information, and automatic documentation of field device maintenance information - all contributing to the on-going efficiency of plant operations and maintenance activities.
Emerson hi-fidelity simulators are also included in the Unit 1 and 2 automation projects.
KCPL selected the Emerson innovative virtual simulator architecture, in which actual controllers are replaced with Ovation virtual controllers that reside on a Microsoft Windows-based personal computer, known as the virtual host.
The virtual controllers, which utilise standard Ovation engineering tools and operator interfaces, run the point scanning, alarming and complete algorithm set, including advanced control algorithms as they exist in the plant controllers.
As such, the virtual controller provides one-on-one functionality that mirrors the actual Ovation controllers that comprise the plant control system.
And, because the virtual technology merges all the benefits of a full simulator into one or more PCs, it offers KCPL a higher level of affordability and scalability - with a significantly reduced footprint.
Incorporation of the virtual simulators will further streamline plant and scrubber start-up at Iatan by validating control/logic loops prior to commissioning.
The simulators will also serve as training tools, enabling operators to fine-tune their skills and familiarise themselves with the new controls, further boosting efficiency.
"The addition of Iatan Unit 2, along with the environmental upgrades to Iatan Unit 1, will more than double the energy supply at the site, while substantially reducing regulated air emissions there.
These projects are important components supporting the continued growth and economic vitality of the area," said Brent Davis, project director, KCPL.
"Emerson, with its experience applying digital automation technologies to supercritical power plants and FGD systems, had the credentials we were looking for".
"We are gratified by KCPL confidence in Emerson and our PlantWeb digital bus approach," said Bob Yeager, president of the Power and Water Solutions division of Emerson, noting that this is the first Emerson contract with KCPL, which has traditionally utilised ABB control systems.
"We are pleased that Emerson advanced automation and control technologies will manage critical power generation processes for KCPL and, in doing so, help ensure an affordable and stable supply of electricity in this growing region".
