Product Overview

The ABB REG670 generator protection IED belongs to ABB Relion 670 series, designed for comprehensive protection, control and supervision of synchronous generators and generator-transformer blocks in thermal, hydro, gas and pumped-storage power plants. It integrates stator differential, rotor earth fault, loss of excitation, over/under voltage, over/under frequency, negative sequence overcurrent, thermal overload and backup protection functions. It supports high-density analog signal sampling, built-in disturbance recording, flexible programmable logic and HSR network redundancy. It can implement primary and backup protection within one single unit to simplify power plant protection cabinet layout. Built for continuous reliable operation in power plant control rooms, this unit mitigates generator damage and grid disturbance risks caused by aging or defective original protection relays. Manufactured to strict power industry standards and fully tested, it serves as a dependable replacement spare part for generator protection system maintenance and fault repair.

Core Application Advantages

• Low Failure Rate Operation: Constructed with industrial-grade materials and circuitry, delivering strong stability and durability to cut recurring maintenance expenses.
• Fast Fault Recovery: Standard withdrawable module design enables quick installation and removal. Engineers can finish system repairs rapidly to minimize power generation downtime losses.
• Wide System Compatibility: Fully compatible with original ABB Relion 670 substation automation architecture. Supports IEC 61850 process bus and multiple communication protocols for seamless SCADA connection, no complex program adjustments needed after installation, bringing zero adaptation cost.

Typical Application Cases

• Industrial System Emergency Maintenance: Emergency replacement of defective generator protection IEDs in power plants to restore full generator protection rapidly.
• Long-term Spare Part Reserve: Kept as regular inventory for thermal power, hydropower and combined-cycle power plants, easing procurement bottlenecks and long lead times of original imported spare parts.
• Automation System Upgrade: Matches legacy generator protection cabinets during power plant reconstruction and digital smart power station transformation.
