ABB REC650 Bay Control IED

Product Overview

The ABB REC650 is a dedicated bay control Intelligent Electronic Device (IED). It provides high-fidelity control and supervision for sub-transmission and distribution substations. This unit manages circuit breakers, disconnectors, and earthing switches. It features integrated synchrocheck and energizing check functions.

Technical Specifications

• Series: Relion® 650.

• Function: Dedicated Bay Control and Supervision.

• Communication: Native IEC 61850 (Editions 1 & 2), DNP 3.0, and IEC 60870-5-103.

• Redundancy: Supports HSR (High-availability Seamless Redundancy) and PRP (Parallel Redundancy Protocol).

• Digital Integration: GOOSE messaging and Sampled Values (IEC 61850-9-2LE).

• Control Capacity: Support for multiple primary objects (Breakers/Disconnectors).

• Display: Graphical HMI with customizable Single Line Diagrams.

• Mounting: 1/2 x 19" 6U rack-mount or flush-mount options.

Key Features and Engineering Advantages

• Pre-Configured Variants: Comes with ready-made configurations for common bay types, drastically reducing engineering time and potential for errors.

• Advanced Synchrocheck: Prevents dangerous out-of-phase closing by verifying voltage, phase angle, and frequency differences between the busbar and the line.

• Programmable Interlocking: Offers flexible logic to ensure that disconnectors and breakers cannot be operated in an unsafe sequence.

• Ethernet Redundancy: Utilizes PRP and HSR to ensure that control commands are never lost due to a single point of network failure.

• High-Speed GOOSE Messaging: Enables peer-to-peer communication for distributed functions like busbar stripping or station-wide interlocking without hardwiring.
