The new digital systems will replace existing controls in an upgrade project that is on a fast track to meet the AEP implementation goals.
Invensys will supply Triconex triple-modular redundant (TMR) turbomachinery controllers.
These Tricon systems will be used on each of Cook Units 1 and 2 main turbine generators, as well as the feed water pump turbines for each unit.
To capture, store, retrieve and analyse all turbine operating data from the Tricon turbine control systems, Invensys will supply the Trilogger high speed, high-resolution control event recording solution.
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.
Since the Tricon redundant control functions and diagnostics are embedded and transparent, each system behaves as a single control device to the engineer or operator.
The Trilogger event recorder is specially designed to match the Tricon high-frequency control scan rates, allowing high resolution data access and analysis for all data points relating to the control of the Cook turbines.
Trilogger software modules allow full on-line event logging, off-line playback for data analysis and presentation, and remote data viewing and recording control.
To support comprehensive control system checkout prior to commissioning, 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.
The new turbine control operator interfaces will be based on Wonderware InTouch human machine interface (HMI) software.
This software provides more user-friendly process visualisation, operation, and easier access to performance and operational data.
This data will be maintained in the Wonderware IndustrialSQL Server real-time plant historian, which provides plant decision-makers with immediate access to detailed, real-time plant information, leading to performance improvement.
Providing comprehensive database functionality for plant process information, the IndustrialSQL Server historian is optimised for operation and maintenance of critical automation applications, where uninterrupted data flow is paramount.
