Invensys to supply upgraded digital
controls
Multiple Invensys capabilities united in fast-track implementation for main turbine generator control, critical reactor pressure control and HMI technology
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 Invensys will supply a Tricon TMR (triple-modular redundant) turbomachinery control system for the integrated turbine and critical reactor pressure control functions

Software enables multiphase flow simulation
Latest software from Invensys Process Systems enables powerful multiphase flow simulation in plant utility and relief networks from within the SIM4ME Portal.
A Tricon TMR system will also be utilised for an all 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 utilised to simulate Triconex controls for system checkout and operator training.

Advanced simulation and modeling in Excel
SIM4ME provides a communication link between SimSci-Esscor PRO/II and the spreadsheet program, Microsoft Excel.
To support the implementation, Invensys will also supply a range of professional services, including on-site testing, start-up services, and specialised training for engineers and operators.
Sargent and Lundy is the AandE (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-megawatt BWR (boiling water reactor) facility utilising 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.
The TMR architecture provides the highest levels of nuclear industry-required reliability by employing three, isolated, parallel control systems and extensive diagnostics integrated into a single Tricon system.
Using two-out-of-three voting, the system provides high-integrity, error-free, uninterrupted process operation with no single point of failure.
For comprehensive control system checkout prior to commissioning, the TRISIM Plus software from SimSci-Esscor will be employed to exactly model the new Triconex control architecture.
TRISIM Plus provides comprehensive simulation, facilitating efficient control system design, training, commissioning and start-up.
This virtual control system precisely duplicates the operational experience in an off-line, low risk manner and dramatically reduces the time required for commissioning.
