VPRO Emergency Trip System Integration

• VPRO system provides primary emergency trip control. Triple redundant boards coordinate trip solenoids through TREx terminals.
• IS200TPROH1CAA supplies speed signals to VPRO. Enables emergency overspeed detection and response.
• VPRO controls up to three trip solenoids between TREx and TRPx terminals. Provides necessary voltage for solenoid operation.
• Sophisticated voting mechanism utilizes 12 relays on TREG board. Ensures redundancy and reliability in emergency trip functions.
• System expansion supports second TREG board via J4. Driven from VPRO for enhanced redundancy and functionality.

TREx Terminal Functions

• TREG, TREL, and TRES terminals control trip solenoids. Critical interface between protection boards and trip hardware.
• TREx terminals ensure safety and integrity of turbine operations. Direct control path for emergency shutdown.
• Coordination with TRPx terminals provides complete solenoid control. Redundant voltage paths prevent single-point failures.
• Protection system operates autonomously from turbine control. Separate module configuration eliminates common-cause failures.
• Triple redundant board arrangement maximizes fault tolerance. Single board failure does not compromise trip capability.

Input Signal Management

• 24 thermocouple inputs dedicated to exhaust over-temperature protection. Precise monitoring for gas turbine temperature anomalies.
• Supports E, J, K, S, and T thermocouple types. Compatible with standard turbine temperature sensors.
• Three analog current inputs for exhaust over-temperature monitoring. Early detection and prevention of overheating issues.
• JP1A and JP1B jumpers configure analog input type. Select 4-20 mA or voltage input per application requirements.
• VPRO supplies 28 V DC power to energize analog transmitters. Ensures continuous and accurate monitoring of critical parameters.

Generator and Speed Monitoring

• Supplies generator signals for backup synchronization check protection. Detects synchronization faults with grid or power sources.
• Magnetic speed pickups connect to second terminal block. Provides vital feedback for rotating machinery speed measurement.
• Speed signals enable emergency overspeed protection. Rapid detection and response to hazardous overspeed conditions.
• Maintains turbine synchronization with grid. Prevents instability and inefficient operation.
• Generator and bus potential transformers wire to first terminal block. Essential sensors integrated for accurate monitoring and control.

Protection System Architecture

• Protection system operates in separate module from turbine control. Complete autonomy ensures safety functions remain independent.
• Triple redundant boards provide fault-tolerant operation. No single point of failure compromises turbine protection.
• TPRO and VPRO work in tandem for comprehensive protection. TPRO supplies signals and inputs; VPRO provides power and coordination.
• Emergency overspeed protection responds in milliseconds. Swift trip solenoid activation prevents turbine damage.
• System designed for GE gas, steam, and hydro turbines. Field-proven reliability across global generation fleets.

Installation and Configuration

• Wire generator and bus PTs, analog inputs, and thermocouples to first terminal block. Critical first step for sensor integration.
• Connect magnetic speed pickups to second terminal block. Essential for speed measurement and overspeed protection.
• Configure JP1A and JP1B jumpers for 4-20 mA or voltage input. Match sensor output type for accurate signal processing.
• Perform thorough verification and testing after wiring. Check connections, signal integrity, and sensor functionality.
