Honeywell in Power
Having lead the way in the advancement of DCS technology in the 1970s, Honeywell is once again on the cutting edge of technology
with Experion® Process Knowledge System (PKS), the worlds first true process knowledge system, by offering Experion with many
features which are specific to the power industry. Honeywell has been serving the power industry with a wide range of automation
products and services for last four decades. They are now pushing the envelope by integrating process control with advanced software
applications and providing unified plant control systems for boiler, turbine and balance of plant for the power generation industry to
better meet their emerging business challenges.
Why Advanced Control for Turbine?
The power generation sector worldwide is under lot of pressure to meet ever increasing power demands. This has resulted in
globalization and liberalization of the power industry, making it more demanding and competitive. It has changed the conventional way
of operating power plants such that Capacity Utilization, Asset Life Conservation, Availability, Reliability, Efficiency and
Environment friendly operation have become the necessity for old as well as upcoming power plants. In this scenario it is very
important for a power station to ramp up or slow down the generation quickly and efficiently to capture the requirements of an open
power market and spot trading.
At the same time, most of the installed power generation base is aging with many units more than twenty years old. Maintenance of
these aging systems has posed challenges for operators, as skilled resources are getting more scarce and costly everyday. These are
the main drivers for upgrading control systems to the latest state-of-the-art technology. Honeywell in association with Wood Group is
geared to provide a complete solution to this problem that includes upgrade of hydraulic parts.
Honeywell Teaming with Wood Group
Honeywell has entered into a partnership with Wood Group to leverage Wood Groups OEM independent expertise in the domain
expertise of turbines, including their governing systems. Wood Group is an international energy services company employing more than
16,000 people operating in over 40 countries. Wood Group Turbine Services, a sister division of Wood Group, has more than 2500
employees in 12 countries. Honeywell in association with Wood Group provides Turbine Control Solutions for: Steam
Turbine Combustion
Turbine Hydroelectric
Turbine Reciprocating
Engine

Integrated Turbine Compressor Control (ITCC)
All mechanical drive applications

Experion PKS for Turbine Control
The Turbine Control Solution offered by Honeywell is based on Experion PKS DCS platform. Experion integrates process control with
advanced solutions and services in an open systems environment that increases efficiency, productivity, safety and security. High
Speed Experion controllers along with high speed servo valve positioner modules and speed sensor input modules meet the stringent
requirement for fast response crucial for turbine control and protection systems. Redundancy features at processor, power supply and
communication levels as well as the unique fault tolerant Ethernet (FTE) based network solution enhance system reliability and
availability. The system is modular so that different turbine configurations, from a simple auxiliary turbine to the most complex main
steam turbine in a large capacity power plant, are readily accommodated. A typical configuration has a single integrated control
platform for turbine control and protection.
The control system can provide both full arc and partial arc (single valve and sequential valve mode) steam admissions under the
appropriate conditions and include a valve management function to handle transfer from one mode to another. The valve management
function also performs valve characterization to relate valve position to steam flow so that the valve transfers can be performed without
a change in load.

Various Turbine Control Functionalities in the Offering
The offered solution takes care of two broad functional categories: turbine regulation, and turbine protection. Apart from the standard
requirement of steam/fuel valve lift control and electronic over speed protection, the following functionalities are in the offerings:
Speed, pressure and load control mode of operation
Initial pressure and limit pressure control mode
Automatic Turbine Startup and Shutdown sequence
Turbine stress evaluator
Online testing of valves and trip devices
Load shading and unit islanding operation
Frequency correction for generated load Automatic
synchronization
HMI Custom Displays and Faceplates
The offering is complete with custom displays and faceplates for ease of monitoring and error free operator actions. The operator
screens are customized to the specific needs of each plant.
Benefits of Integrated Turbine Control for the Customer
Honeywell offers an integrated control system for boiler, turbine and balance of plant which helps for better coordination among major
plant equipment, such as boiler, turbine, generator, boiler auxiliaries, feed water pumps, heaters, condensers etc. Other benefits that
customers enjoy with integrated control system are:
Common hardware and software platform
Common pool of maintenance spares
Common engineering, diagnostic and documentation console
Ease of operation and training
Common operator interface for the complete plant
Effective data reporting and archival being a common system throughout the plant
Complete solution including hydraulics part from one source Honeywell
Increased reliability and availability through redundancy features of the Experion system
