ABB REB670 1MRK002820-AC

This is a high-end device that is widely used in the field of power system protection and control.

1. Main Functions and Features
Core Protection Function:
At its core is current differential protection, the most sensitive, fastest, and most selective primary protection scheme for protecting transmission lines.

Line Differential Protection: By comparing the amplitude and phase of the currents at both ends of the line, it accurately detects faults within the line (such as phase-to-phase shorts and ground faults) and instantly trips the circuit breaker. It is also highly sensitive to high-resistance ground faults at the end of the line.

Backup Protection: In addition to primary protection, it also integrates a complete set of backup protection functions, including:

Distance protection (with sectional and directional elements)

Overcurrent protection (directional and non-directional)

Zero-sequence overcurrent protection (ground fault)

Auto-reclosing

Voltage protection

Frequency protection

Circuit breaker failure protection: A built-in Back-up Frequency Delay (BFD) function activates the backup trip logic if the circuit breaker fails to open normally after a command is issued.

2.Control and Monitoring Functions:
Measurement and Metering: Provides high-precision measurements of voltage, current, power, power factor, frequency, and energy.

Event Logging: Detailed records of all operations, alarms, and fault events with precise timestamps.

Fault Recording: Records current and voltage waveforms before and after a fault for analysis.

Sequential Event Recording: Records the sequence of all input/output signal changes with millisecond-level accuracy.

Remote Control: Supports remote opening and closing of circuit breakers, disconnectors, and other devices.

Communication and integration capabilities:

This is the strength of the REB670 series, which supports multiple international standard protocols and ensures seamless integration into substation automation systems.

Communication Protocol:

IEC 61850 (GOOSE/SV for station control and process layers)

IEC 60870-5-103/101

DNP3.0

Modbus

Hardware Interface: Multiple Ethernet ports, fiber optic interfaces, and serial communication ports are provided to meet diverse connectivity requirements.

Key Features:

High Reliability: Redundant power supplies and robust hardware design make it suitable for harsh power environments.

High Safety: Built-in advanced algorithms such as CT saturation detection and capacitor current compensation prevent false or ineffective protection.

User-Friendly: Configuration and commissioning can be performed via a local HMI (human-machine interface) or professional PC tools such as PCM600, with an intuitive graphical interface.

Modular Design: Flexible I/O modules can be configured to meet specific needs.

3. Typical Applications
The REB670 is primarily designed for medium- to ultra-high-voltage transmission networks requiring high-performance protection. Specific application scenarios include:

Differential protection of two-terminal or three-terminal transmission lines (T-connected lines)

Power utility main grids

Incoming and tie lines for large industrial plants and mines

Grid-connected lines for renewable energy power plants (such as wind farms and photovoltaic power plants)
