Invensys implementing InFusion-based Generation Management System for Williams Power
Posted 06 July 2006Invensys implementing InFusion-based Generation Management System for Williams Power
System to provide foundation for wide area real time production monitoring and dispatch control of all Williams’ generation assets
Williams Power has selected Invensys to implement an InFusion-based
Generation Management System (GMS) for its fleet of electrical generation
assets. These assets include two company-owned power plants and six contracted
facilities located across seven states.
The new system will integrate data from many different automation systems and
applications to help Williams precisely schedule the delivery of generation
capacity from each plant according to changing demand from contracted markets.
The GMS will monitor demand trend data by communicating with the three
contracted ISO (Independent System Transmission Operator) organizations that
serve California (CAISO), the Midwest (MISO) and Mid-Atlantic states (PJM). In
the competitive deregulated generation market, the ISOs are responsible for
monitoring and directing the flow of wholesale electric power into and
throughout the distribution grids that serve their regional markets.
Having all plant data and market demand data in a centralized business decision
support environment will allow Williams to provide set point dispatch control
for production from the generating plants on an hourly basis. This real time
scheduling will help prevent shortfalls in capacity, as well as the generation
of too much electricity, minimizing economic risk in the business and optimizing
the production value of each Williams generation asset.
The new system will be engineered using new modular power industry applications
created in the InFusion Engineering Environment. This will allow these
applications to be deployed on different automation systems across the Williams
generation fleet.
InFusion Access and Historian will collect and model data from a variety of
device types at the eight power plants, constantly comparing the production data
in real time with customer demand trend data from the ISOs throughout each day.
The InFusion View graphical user interface and SuiteVoyager for InFusion Web
portal will provide a local human machine interface (HMI) for operator
visualization and provide authorized managers with secure remote access to GMS
information.
Invensys will implement the Williams GMS connection to the regional ISOs using a
LiveData server using ICCP (Inter-Control Center Protocol), which enables
real-time bi-directional flow of remote data across multiple protocols.
The Invensys Generation Management System replaces an existing SCADA system. The
new Infusion-based system will provide Williams Power with a more flexible,
easier-to-deploy, standards-based data acquisition and business decision support
platform that will be able to adapt to future changes in asset configuration and
energy market characteristics.
The Invensys GMS implementation builds on more than a dozen years of prior
Invensys experience with units of the Williams Companies. Williams has Foxboro
I/A Series automation systems installed at seven gas processing sites.
