11 October 2006 -- Invensys Process Systems will supply Energy Northwest with Triconex digital control systems for integrated main turbine and reactor pressure control, and for turbine trip controls at the Columbia Nuclear Generating Station, near Richland, Washington, US.
Invensys will supply a Tricon TMR (triple-modular redundant) turbomachinery control system for the integrated turbine and critical reactor pressure control functions. A Tricon TMR system will also be utilized for a new turbine trip digital control scheme, including lube oil, thrust, vacuum pressure and overspeed. The Tricon systems will be integrated with Wonderware's InTouch HMI (human machine interface) software to bring together more than 600 critical monitoring and control system I/O points from the turbine and generator.
In addition, TRISIM Plus software from SimSci-Esscor will be utilized to simulate Triconex controls for system checkout and operator training. To support the implementation, Invensys will also supply a range of professional services, including on-site testing, start-up services, and specialized training for engineers and operators. Sargent & Lundy is the architecture and engineering firm, providing a range of engineering services including conceptual study, specification development, bid evaluation, plant modification package, procedure update, installation support and project management support.
The Columbia Nuclear Generating Station is a 1,250-MW boiling water reactor (BWR) facility utilizing a Westinghouse main turbine. The new digital systems will replace existing controls in an upgrade project that is on a fast track to meet aggressive Energy Northwest implementation goals.
