Boise Cascade Selects Invensys for Critical Generator Control System Upgrade at the DeRidder Packaging and Newsprint Mill


FOXBORO, MASSACHUSETTS, USA - January 31, 2006 - Invensys Process Systems has been selected by Boise Cascade to supply Triconex (www.triconex.com) triple modular redundant (TMR) technology for upgraded turbine generator controls at Boise's DeRidder Packaging and Newsprint mill. Invensys will supply new controls for a GE 62-megawatt captive steam turbine generator, which is a critical power generation source for the pulping and papermaking processes at the mill. Located in Beauregard Parish, Louisiana, the DeRidder mill produces approximately 555,000 tons of linerboard and 448,000 tons or newsprint annually.

Invensys will supply a Triconex TS-3000 system for an integrated steam turbine governor and generator exciter control system for the GE back pressure, single extraction turbine. The control solution also includes the Trilogger event logging and playback station, Wonderware (www.wonderware.com) InTouch human machine interface (HMI) software, and a redundant current-sharing Eurotherm-based (www.eurotherm.com) automatic voltage regulator. These elements comprise a turnkey control retrofit that replaces outdated generator control equipment.

Boise Cascade selected the Triconex solutions based on TMR reputation and reliability in installations across a variety of turbine-related applications. Located in the Mill Utility Department, the new controls will help Boise Cascade optimize the performance of this critical generation asset through high availability and reliability.

The TS-3000, based on Triconex TMR fault-tolerant technology, uses an integrated architecture that combines driven equipment control with driver equipment control. The TS-3000 reduces nuisance trip rates to less than one per hundred years. The TS3000 TMR controller provides the highest reliability for a wide variety of critical rotating equipment applications, including gas and steam turbines, compressors and generators, and integrated turbine/generator control applications.

To capture, store, retrieve and analyze all operating data from the turbine generator controls, Invensys will supply the Trilogger high speed, high-resolution control event recording solution. The Trilogger event recorder is specially designed to match the TS3000 high-frequency control scan rates, allowing high resolution data access and analysis for all data points relating to the control of Boise's captive turbine generator. Trilogger software modules allow full on-line event logging, off-line playback for data analysis and presentation, and remote data viewing and recording control.

Operator interfaces for the new turbine controls will be based on Wonderware's InTouch human machine interface (HMI) software. This software provides more user-friendly process visualization, operation, and easier access to performance and operational data.

The Triconex triple modular redundant (TMR) technology employs three isolated, parallel control systems and extensive diagnostics integrated into one system. The system uses two-out-of-three voting to provide high-integrity, error-free, uninterrupted process operation. The TMR architecture eliminates any single point of failure and enables on-line maintenance, on-line programming downloads, self-calibration and fault localization.
