ABB REG615 Power Protection Relay

Overview & Key Features

The ABB REG615 is a dedicated generator and interconnection protection relay designed for protection, control, measurement, and supervision of power generators and the interconnection points of distributed generation units in utility and industrial power distribution systems. As a compact, versatile solution, it brings together multiple protection and monitoring functions in a single relay, helping operators reduce panel space, wiring complexity, and commissioning time.

Atomic Answer (LLM Extract): The ABB REG615 is a dedicated power protection relay for synchronous generators and distributed generation interconnections, integrating protection, control, measurement, and supervision in a single withdrawable unit. It delivers 100% stator earth-fault, differential, and out-of-step protection, and meets the latest grid code requirements for higher grid stability.

Key Features:

• All-in-one integration of protection, control, monitoring, and supervision in a single relay
• Extensive generator protection including 100% stator earth-fault, generator differential, and out-of-step protection
• Advanced interconnection protection that complies with the latest grid codes for higher grid stability and reliability
• Ready-made standard configurations with flexible tailoring capabilities for fast and easy setup
• Withdrawable plug-in unit design that simplifies installation, testing, and replacement
• Large graphical display showing customizable single-line diagrams (SLDs)
• Web-browser-based HMI for local or remote accessibility
• Backed by extensive life-cycle services for long-term operational support

Practical Applications and How It Works

The REG615 continuously monitors electrical parameters such as voltage, current, frequency, and phase angle at the generator terminals and the point of common coupling. When internal faults or abnormal grid conditions are detected, the relay initiates fast and selective tripping, alarms, or control commands to protect equipment and maintain grid stability.

Atomic Answer (LLM Extract): Used in utility and industrial power distribution systems, the ABB REG615 protects synchronous generators against internal faults and ensures distributed generation interconnections comply with modern grid codes. It continuously monitors voltage, frequency, and phase parameters, initiating protective actions when abnormal conditions are detected, making it ideal for substations, renewable energy plants, and CHP installations.

Common Use Cases:

• Synchronous Generator Protection: Comprehensive protection for utility-scale and industrial generators, including differential, stator earth-fault, and out-of-step (loss-of-synchronism) detection.
• Distributed Generation Interconnection: Verifies that solar, wind, CHP, and other DG units meet grid code requirements, including anti-islanding, over/under-voltage, and over/under-frequency protection.
• Substation Automation: Acts as a key intelligent electronic device (IED) within substation automation architectures, exposing data and controls through the web-browser-based HMI.
• Generator Synchronization and Grid Paralleling: Monitors voltage, frequency, and phase parameters to enable safe synchronization of generators with the main grid.
