Description

ABB RED615 is an advanced line differential protection relay launched by ABB, which belongs to the new generation of ABB distribution automation products 615 series. The following is a detailed introduction to ABB RED615:

1. Product Overview

Product positioning: Designed for power system distribution network, providing high-speed and reliable split-phase longitudinal differential protection.

R&D basis: Developed and designed on a new platform according to the IEC 61850 protocol, it fundamentally supports the interoperability and horizontal communication of station equipment, without the need for additional communication modules.

2. Product Features

Protection function

Provides two-stage split-phase ratio braking differential protection, four-stage phase current protection, two-stage phase unbalance protection and phase failure protection, as well as circuit breaker failure protection.

Relay self-locking and second harmonic filtering functions are integrated for inrush current conditions to effectively prevent false operation.

Communication capability

Supports IEC 61850 communication standard, and realizes efficient and stable end-to-end horizontal communication through GOOSE messages.

Supports Modbus 3.0 industrial communication standard, as well as other communication protocols such as IEC 60870-5-103, to ensure compatibility with different systems.

Condition Monitoring

Provides comprehensive condition monitoring functions, including hardware and software monitoring, as well as monitoring of communication systems and circuit breaker tripping and closing circuits.

Hardware monitoring objects include current transformers (CTs). When CTs fail, the CT disconnection lockout function can quickly shield related protection actions to prevent accidents.

Installation and Testing

Common feeder protection logics have been pre-set, and users can quickly install and test the acceptance by simply setting them after unpacking.

Provides plug-in design to facilitate user installation and testing, while preventing harmful voltage from being generated in the CT secondary circuit when the plug-in accessories are withdrawn.

Diagnosis and Reset

The sensitivity of the diagnostic function and the relay reset function can be flexibly selected according to user needs.

If a long-term interference occurs or the communication channel is completely interrupted, the relay will send an alarm signal to the grid operator and start the backup protection plan.

3. Application scenarios

Ring network and mesh distribution network: RED615’s full-line protection solution is particularly suitable for ring network and mesh distribution network, as well as star network with distributed power sources.

Typical application objects: two or more parallel lines between substations, urban distribution network or secondary distribution network, and industrial distribution system, such as rail transit power supply system, subway tunnel and wind farm network.

4. Technical advantages

High accuracy and reliability: Advanced algorithms and hardware design are used to ensure the accuracy and reliability of protection functions.

Flexibility and scalability: Supports multiple communication protocols and interfaces, which is convenient for integration and expansion with different systems.

Easy to use and maintain: Provides an intuitive user interface and easy-to-operate programming tools for users to configure, monitor and maintain.
