4. Product Introduction
The ABB REG670 is a flagship member of the Relion® 670 series, designed to provide state-of-the-art protection, control, and monitoring for generators and large motors in critical power generation facilities. It represents the pinnacle of ABB’s protection technology, offering unparalleled flexibility, performance, and cybersecurity.Key Capabilities:
- Comprehensive Generator Protection: Includes advanced functions like 100% stator earth fault protection (using 3rd harmonic or injection methods), loss of excitation, out-of-step protection, and high-impedance differential protection.
- IEC 61850 Native: Built from the ground up to support IEC 61850 Edition 2, enabling seamless integration into modern digital substations and smart grid architectures. Supports GOOSE messaging for high-speed interlocking and trip schemes.
- Redundancy Options: Supports hot-standby redundancy configurations to ensure maximum availability for critical generation assets. If the primary unit fails, the secondary takes over instantly without disruption.
- Advanced Diagnostics: Features extensive self-monitoring, condition monitoring, and disturbance recording capabilities to aid in predictive maintenance and root cause analysis.
- Cybersecurity: Designed with “security by design” principles, complying with IEC 62351 standards to protect against cyber threats.
The REG670 is the modern successor to legacy ABB generator protection relays (such as the REG216, REG316, and REG416), offering significant improvements in speed, accuracy, communication, and ease of engineering via the PCM600 software suite. We supply genuine new surplus units with full factory documentation.
5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Part Relevance | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No Power LEDs | Auxiliary Supply Issue | ❌ Low | Measure voltage at auxiliary terminals; check fuses | Verify supply range (DC/AC) matches rating |
| “Hardware Fault” LED | Internal Module Failure | ✅ High | Check event log via PCM600 or local HMI | Restart unit; if persistent, contact support for RMA |
| Communication Timeout | Network Config/IP Conflict | ⚠️ Med | Ping device IP; check VLAN settings; verify SCL file | Ensure switch port config matches relay settings |
| False Differential Trip | CT Saturation/Wiring Error | ⚠️ Med | Review disturbance records; check CT polarity/ratios | Perform secondary injection test; verify bias settings |
| GOOSE Message Missing | Subscription/Config Error | ⚠️ Med | Check GOOSE subscriber configuration in PCM600 | Verify publisher MAC-ID and AppID match |
| 100% Earth Fault Alarm | 3rd Harmonic Level Low | ⚠️ Med | Check generator load; verify neutral PT connection | Adjust sensitivity settings based on actual harmonic levels |
| Display Frozen/Unresponsive | Software Hang | ⚠️ Med | Try remote access via PCM600; reboot if possible | Update firmware if compatible; check for known bugs |
Closing Suggestion: For complex issues involving protection logic or communication protocols:
- Export the Disturbance Record and Event Log.
- Capture the Configuration File (.IED) from PCM600.
- Provide these files to technical support for detailed analysis.
Our engineers can typically diagnose communication or logic issues within 2 hours using these data points.
6. Frequently Asked Questions (FAQ)
Q1: What are the main differences between REG670 and the older REG216/REG316?A: The REG670 is a generational leap forward:
- Architecture: REG670 uses a modern, high-speed processor architecture vs. the modular/hardware-based logic of REG216.
- Communication: REG670 natively supports IEC 61850 (GOOSE/MMS), whereas REG216 relies on serial protocols (Modbus/Profibus) with limited bandwidth.
- Protection Accuracy: REG670 offers higher precision, faster trip times, and advanced algorithms (e.g., adaptive bias, harmonic restraint).
- Engineering: Configured entirely via PCM600 software with drag-and-drop logic, compared to dip-switches and complex menu navigation in legacy units.
- Cybersecurity: REG670 includes built-in security features (user roles, encryption) absent in legacy models.
Q2: Can the REG670 be configured for redundant operation?A: Yes. The REG670 supports hot-standby redundancy. Two identical REG670 units can be paired so that one acts as the primary and the other as a backup. They continuously synchronize their data and status. If the primary unit detects an internal fault or loses power, the backup takes over protection functions seamlessly (typically within milliseconds), ensuring no gap in protection coverage. This is critical for large generators where unplanned trips are extremely costly.Q3: Does the REG670 support 100% Stator Earth Fault Protection?A: Absolutely. The REG670 provides comprehensive stator earth fault protection options:
- Fundamental Frequency (59N): For faults away from the neutral.
- Third Harmonic Voltage (27H/59H): For faults near the neutral point (covering the remaining ~90-95%).
- Injection Method (95%+): Optional low-frequency signal injection for true 100% coverage, even when the generator is offline or at standstill.
This ensures complete protection of the generator stator winding against ground faults.
Q4: What software is used to configure the REG670?A: The ABB PCM600 (Protection and Control Manager 600) software is the standard engineering tool. It provides:
- Intuitive graphical configuration of protection functions.
- IEC 61850 system configuration (SCL file handling).
- Real-time monitoring and testing.
- Disturbance record analysis.
- Firmware management.
PCM600 is compatible with Windows 10/11 and supports all Relion 615/670 series devices.
Q5: Is the REG670 suitable for wind turbine generator protection?A: Yes. The REG670 is widely used in wind power applications. It includes specific features for wind turbines, such as:
- Handling variable frequency operations.
- Specific logic for collector grid protection.
- Robust communication for SCADA integration in remote locations.
- Ride-through capability compliance (grid code support).
Its rugged design and wide temperature range make it ideal for harsh wind farm environments.
Q6: How do you handle firmware updates and cybersecurity?A:
- Firmware: Updates are performed securely via PCM600 using signed firmware files to prevent tampering.
- Cybersecurity: The REG670 supports role-based access control (RBAC), secure shell (SSH), TLS encryption for MMS, and IEC 62351 compliance. Unused ports can be disabled, and password policies can be enforced to meet NERC CIP or similar regulatory requirements.
Q7: What is the warranty and support status for REG670?A: As a current-generation product, the REG670 is fully supported by ABB with long-term availability guarantees.
- Warranty: We provide a 12-month warranty on our New Surplus units (covering hardware defects).
- Support: Full access to ABB technical documentation, firmware updates, and software tools.
- Lifecycle: Expected service life exceeds 15-20 years with ongoing support.
