ABB GHR9010100R0002
Product Introduction
The ABB GHR9010100R0002 is a REG670 series advanced generator protection relay engineered for critical power generation assets. As part of ABB’s Relion® 670 product line, this device integrates comprehensive protection, control, and monitoring functions specifically optimized for hydro, gas, steam, and combined-cycle generators. Its core role is safeguarding multi-million-dollar rotating equipment against electrical faults, abnormal operating conditions, and grid instability events through microprocessor-based algorithms.
Technically positioned as a multifunctional protection IED (Intelligent Electronic Device), the GHR9010100R0002 combines traditional protection elements (differential, overcurrent) with specialized functions like stator earth fault detection (64G), inadvertent energization (50IE), and generator synchronization (25). Unique among its class, it features integrated synchrophasor measurement (PMU) compliant with IEEE C37.118, enabling wide-area monitoring and grid stability applications. Within modern power systems, this relay serves as the primary defense against generator damage while providing critical data to plant DCS/SCADA systems via IEC 61850 communication.
Core Advantages and Technical Highlights
Multi-Layer Generator Protection: The ABB GHR9010100R0002 provides 20+ protection functions including 100% stator ground fault detection using third-harmonic voltage monitoring and sensitive directional neutral overcurrent. Its adaptive differential protection automatically compensates for CT saturation during severe faults.
Grid Compliance & Synchrophasor Technology: With IEEE C37.118-2005/2011 compliant PMU functionality, the relay delivers 30/60 frames-per-second phasor measurements synchronized to GPS (via IRIG-B or PPS). This enables:
Real-time grid stability monitoring
NERC PRC-002 compliance
Oscillation detection for torsional stress prevention
Cybersecurity & Communication Robustness: Features hardware-enforced IEC 62351 security for GOOSE messaging, role-based access control, and audit trails. Dual Ethernet ports support PRP/HSR redundancy for zero-packet-loss communication in IEC 61850 substations.
Advanced Logic & Coordination: Integrated CFC (Continuous Function Chart) editor allows custom logic creation without additional PLCs. Sequence-of-Events (SOE) recording captures 1024 events with 1ms resolution for forensic analysis.
Adaptive HMI & Diagnostics: The 5.7″ color display renders real-time vector diagrams, oscillography, and thermal overload curves. Continuous self-supervision monitors hardware health, CT/VT circuits, and protection algorithm integrity.
Typical Application Scenarios
Hydroelectric Plants: Protects generators against stator faults (87G), overexcitation (24), and motoring (32) during turbine shutdown. PMU functionality monitors grid angle stability during load rejection transients.
Combined-Cycle Gas Turbines (CCGT): Implements loss-of-field (40) and out-of-step (78) protection during grid disturbances. GOOSE messaging coordinates with switchgear for <100ms fault clearance.
Industrial Cogeneration: Prevents back-feeding accidents with directional power protection (32/32R). IEC 61850 integration enables seamless control from plant DCS.
Offshore Wind Farms: Synchronizes generators via IEC 60255-181 compliant sync-check (25). Withstands salt fog (IEC 60068-2-52) and vibration (IEC 60255-21).
Black Start Facilities: Controls generator excitation during system restoration. Records voltage recovery waveforms via 128-sample/cycle oscillography.
Peaking Plants: Thermal replica algorithms model rotor heating during rapid starts/stops. Binary inputs interface with turbine safety systems (TSI).

Installation, Commissioning and Maintenance Instructions
Installation Preparation: Verify CT/VT ratings match relay specifications (1A/5A CTs, 67V/120V VTs). Ensure proper grounding of shield wires at CT/VT cabinets. Maintain 100mm clearance from high-voltage cables. Use shielded twisted-pair cables for binary I/O. Confirm DC supply stability (±15% ripple max).
Maintenance Suggestions: Perform annual secondary injection tests using ABB’s PCM600 software. Monitor “Watchdog” LED status monthly. Backup configuration files before firmware upgrades. Check fiber-optic connections (if used) for attenuation (<3dB loss). Calibrate analog inputs every 4 years using certified test sets. Replace backup battery (CR2032) every 5 years. Analyze disturbance records after grid events to validate protection logic.
