Product Overview

The ABB REF615 is a key member of ABB’s Relion® product family and part of its 615 protection and control series. It’s a compact, withdrawable-unit design that offers comprehensive protection, control, measurement, and supervision functionalities for overhead lines and cable feeders in various distribution networks, including radial, looped, and meshed systems, with or without distributed power generation.

It’s engineered to fully leverage the IEC 61850 standard for seamless communication and interoperability among substation automation devices. The REF615 can provide both main and backup protection, ensuring reliable operation of the power system.

Product Parameters (Key Features & Specifications)

While specific numerical parameters can vary slightly based on the exact configuration and product version, here’s a general overview of its key features and specifications:

• Protection Functions:
  • Overcurrent Protection: Time and instantaneous overcurrent (directional and non-directional).
  • Earth-Fault Protection: Non-directional and directional earth-fault, sensitive earth fault (SEF), and advanced multi-frequency admittance-based earth-fault protection for higher sensitivity and selectivity.
  • Voltage Protection: Undervoltage and overvoltage protection.
  • Other Protections: Negative sequence overcurrent, phase discontinuity, breaker failure, thermal overload, arc protection, and optional high impedance fault (HIZ) protection.
• Control & Measurement:
  • Integrated basic control functionality for one circuit breaker via the front panel HMI or remote control system.
  • Extensive metering and measurement functions (voltage, current, power, frequency).
• Communication Protocols:
  • IEC 61850 Editions 1 & 2: Including GOOSE messaging for high-speed inter-IED communication, HSR (High-availability Seamless Redundancy) and PRP (Parallel Redundancy Protocol) for communication redundancy, and IEC 61850-9-2 LE for sampled values.
  • Other Protocols: IEC 60870-5-103, Modbus®, and DNP3.
  • Time Synchronization: IEEE 1588 V2 (PTP) for high-accuracy time synchronization.
• Hardware:
  • Compact and withdrawable-unit design.
  • Large graphical display for showing customizable Single Line Diagrams (SLDs), accessible locally or via a web browser.
  • Multiple Ethernet ports (optical and galvanic) for flexible network connectivity.
  • Can be configured for conventional Current Transformers (CTs) and Voltage Transformers (VTs), or with sensor inputs.
• Configurations: Available in multiple standard configurations to fit various feeder application needs, with flexibility for customization via PCM600 software.

Product Advantages

• Comprehensive Protection: Offers a wide range of protection functions for various fault types, ensuring maximum feeder reliability.
• Enhanced Selectivity & Sensitivity: Features like multi-frequency admittance-based earth-fault protection improve detection of challenging faults.
• Advanced Communication: Full support for IEC 61850, including GOOSE and redundant communication protocols (HSR/PRP), enables seamless integration into modern substation automation systems and distributed control schemes.
• Flexibility & Scalability: Available in various standard configurations and can be customized to specific application requirements, adaptable to different network types (isolated neutral, resistance-earthed, compensated, solidly earthed).
• Ease of Use: User-friendly Human Machine Interface (HMI) with a large graphical display and web-browser-based access simplifies operation and monitoring.
• Reduced Wiring: IEC 61850-9-2 LE support allows for less wiring and supervised communication, simplifying installation.
• Reliability: Robust design and advanced features like auto-reclose functions contribute to rapid fault clearance and service restoration, minimizing downtime.
• Integrated Functionality: Combines protection, control, measurement, and supervision in a single device, offering a compact and cost-effective solution.

Precautions

• Proper Configuration: The REF615 is highly configurable. Incorrect settings can lead to misoperation or failure to protect the system. Always ensure settings are carefully calculated and validated by qualified personnel.
• Earthing/Grounding: Pay close attention to the earthing/grounding scheme of the network when selecting and configuring the REF615, as its performance depends on it.
• Firmware Updates: Regularly check for and apply necessary firmware updates from ABB to ensure optimal performance, security, and access to the latest features.
• Environmental Conditions: Ensure the installation environment meets the specified temperature, humidity, and vibration limits to guarantee the device’s longevity and reliable operation.
• Personnel Training: Only trained and authorized personnel should install, commission, operate, and maintain the REF615.
• Cybersecurity: Implement appropriate cybersecurity measures, especially when integrating the REF615 into a larger network via IEC 61850, to protect against unauthorized access and cyber threats.

Product Applications

The ABB REF615 is primarily used for the protection and control of:

• Overhead Lines: Protecting overhead power transmission and distribution lines from various faults.
• Cable Feeders: Safeguarding underground cable feeders in distribution networks.
• Utility Substations: Providing main and backup protection for feeders within utility substations.
• Industrial Power Systems: Ensuring reliable power supply and protection for industrial facilities and their internal distribution networks.
• Radial, Looped, and Meshed Distribution Networks: Adaptable to various network topologies, including those with distributed power generation (e.g., solar farms, wind turbines).
• Specific Network Types: Applicable in isolated neutral, resistance-earthed, compensated, and solidly earthed networks.
