ABB REG615 | Generator Protection Relay for Distributed Generation

Product Description: ABB REG615 Generator Protection Relay

The ABB REG615 is a reliable generator protection relay from ABB’s Relion® 615 series, designed for small to medium-sized synchronous generators in power plants and industrial facilities. This intelligent electronic device (IED) combines protection, control, measurement, and monitoring functions into one unit, ensuring efficient and safe operation of generators.

The REG615 provides extensive protection for generators, including differential protection, overcurrent, earth-fault, loss-of-field, over/under-voltage, and frequency protection. Its control functions encompass breaker control, disconnector control, interlocking, and automatic reclosing, making it a versatile tool for managing generator faults and maintaining power system stability.

In addition to protection, the REG615 offers advanced monitoring and recording capabilities, such as disturbance recording, event logging, and fault recording. These features are essential for fault analysis and troubleshooting, providing valuable insights into system performance. It also supports several communication protocols—IEC 61850, Modbus, DNP3, and SPA bus—allowing for seamless integration into SCADA and DCS systems for real-time monitoring and control.

With a user-friendly local HMI featuring an LCD display and keypad, the REG615 ensures easy operation. Additionally, remote access is available via communication ports, providing flexibility in system management. Its compact and modular design enables easy installation and scalability, ensuring that the device can be adapted to various power generation systems.
