Description

Description:

The GEDS200SLCCG1AFGis a Secondary Logic Control Card(SLCC)designed for GE Speedtronic Mark V gas turbine control systems.This critical module provides redundant processing and I/O interface capabilities to ensure continuous,reliable turbine operation.

Application Scenarios:

During a peak summer demand period,a power generation facility’s GE Frame 6B gas turbine experienced an unexpected control system switchover to the backup processor.Investigation revealed the primaryDS200SLCCG1AFGmodule had detected an internal fault and automatically transferred control to the secondary system without turbine trip.This SLCC module is responsible for processing critical I/O signals including fuel valve commands,ignition sequences,and vibration monitoring.The redundant design allowed continuous power generation while maintenance replaced the faultyDS200SLCCG1AFGmodule,preventing grid instability and revenue loss during high-demand conditions.

Technical Principles and Innovative Values:

Innovation Point 1:Triple Modular Redundancy Architecture.TheDS200SLCCG1AFGoperates within GE’s patented TMR system where three identical control channels process identical data simultaneously.The module uses advanced voting logic to compare outputs across all three channels,automatically isolating any channel that deviates from consensus.This architecture provides fault-tolerant operation critical for continuous power generation applications.

Innovation Point 2:Advanced Diagnostics and Prognostics.The module incorporates comprehensive self-diagnostics that continuously monitor processor health,memory integrity,and I/O functionality.Predictive algorithms analyze performance trends to identify potential issues before they cause system faults,enabling proactive maintenance and reducing unplanned outages.

Application Cases and Industry Value:

A combined cycle power plant implemented a control system upgrade usingDS200SLCCG1AFGmodules across their three gas turbine units.During a lightning storm that caused voltage transients,the redundant SLCC modules maintained stable turbine operation while similar non-redundant systems at neighboring facilities tripped offline.The plant demonstrated 99.95%availability over the subsequent year,with theDS200SLCCG1AFGmodules’reliability contributing to an estimated$2.8M in avoided outage costs and lost revenue.

Installation,Maintenance,and Full-Cycle Support:

Installation&Maintenance:TheDS200SLCCG1AFGrequires careful handling with ESD protection.Installation must follow GE’s detailed procedures including rack grounding verification and firmware compatibility checks.Regular maintenance includes monitoring diagnostic logs,verifying heat sink temperatures,and performing scheduled firmware updates.Always maintain configuration backups to facilitate rapid recovery.
