Functional Features

1. Independent Emergency Protection System
   • Triple Redundancy: Three VPRO boards process data in parallel, using a 2-out-of-3 voting mechanism to eliminate single-point failures .
   • Overspeed Protection: Triggers a trip signal within 0.1 seconds when speed exceeds 110% of rated value, cutting fuel supply and braking the turbine .
   • Controller-Independent Operation: Executes emergency shutdown via hardwired logic even if the main controller fails .
2. Real-Time Monitoring & Diagnostics
   • Multi-Parameter Surveillance: Simultaneously collects speed, vibration, temperature, and pressure signals, analyzing anomalies with predictive algorithms .
   • Self-Diagnostics: Continuously monitors hardware health (e.g., power voltage, processor load), auto-switching to redundant channels and logging events during faults .
3. Industrial-Grade Reliability
   • EMI/RFI Immunity: Opto-isolated interfaces and shielded cabling minimize interference .
   • Hot-Swap Capability: Modules can be replaced without system downtime .
   • Longevity: Industrial-grade capacitors and resistors ensure an MTBF exceeding 100,000 hours .
4. Flexible Configuration
   • Modular Design: Works with TREG terminal boards and TRIP boards to build multi-level protection networks .
   • Programmable Logic: Customizable protection logic (e.g., delay times, trigger thresholds) via GE Speedtronic Mark VI 组态 software .

Application Scenarios

1. Power Generation
   • Steam/Gas Turbines: Prevents overspeed in coal-fired and gas power plants, ensuring safe operation of power generation systems .
   • Combined-Cycle Units: Monitors synchronization between gas and steam turbines in integrated power plants .
