Hitachi‑Energy (ABB) REC670 Product Description
The REC670 (order code 1MRK004814‑xx) is a bay‑control intelligent electronic device (IED) within the Relion® 670 series for high‑voltage transmission substations. It executes bay‑level control, interlocking, measurement, alarm supervision and breaker‑failure protection for switchgear. Supports single‑breaker, double‑breaker and 1‑1/2‑breaker substation layouts. The large front‑panel HMI enables local operation, event‑log and disturbance‑record review. It fully supports IEC 61850 including process‑bus sampled‑values, HSR redundancy and precision time‑sync for digital‑substation deployment. Hardware is modular; application configuration and parameter setting must be completed via PCM600 tool before commissioning.
Product Features
- Bay‑control IED for transmission‑voltage switchgear; controls breakers, disconnectors and earthing‑switches with built‑in interlock‑logic
- Multiple application variants: A30(single‑breaker), B30(double‑breaker), C30(1‑1/2‑breaker), D30(with PMU phasor‑measurement function)
- Integrated protection functions: breaker‑failure protection, stub‑protection, over‑current / voltage / frequency protection elements, broken‑conductor detection
- Full IEC 61850 compliance: MMS communication, GOOSE messaging, process‑bus 9‑2LE sampled‑values, HSR ring‑redundancy, IEEE‑1588 time‑synchronization
- Front‑panel graphical HMI for local control, setting‑group switching, fault‑event & disturbance‑recorder access; large‑capacity internal event‑buffer storage
- Modular plug‑in hardware design: configurable binary‑input, binary‑output, analogue‑input modules; wide‑range DC auxiliary power‑supply
- Programmed and commissioned by PCM600 engineering software; supports setting‑group switching for different operating‑conditions
- Rack‑mount 19‑inch cabinet installation, IP20; compliant with IEC‑60255 EMC immunity standards for substation harsh‑EMI environment
Application Scenarios
- HV / EHV transmission substation bay‑level control‑and‑supervision for circuit‑breaker bays
- Digital‑substation projects using IEC‑61850 process‑bus architecture for merging‑unit signal interfaces
- 1‑1/2‑breaker and double‑bus‑bar substation configurations requiring complex switchgear interlocking logic
- Retrofit‑replacement & spare‑part maintenance for existing Relion‑670‑series substation automation systems
- Utility power‑grid, industrial large‑power plant and metallurgical‑plant high‑voltage switch‑yard control systems
- Substation‑wide PMU synchrophasor‑measurement applications for wide‑area monitoring (D30 variant)
Frequently Asked Questions
A1: REC670 is bay‑control unit, focus on switch‑gear control, interlocking and breaker‑failure protection. REL670 is line distance‑protection main‑protection IED, core function is transmission‑line fault‑protection; they cannot substitute each other directly.
A2: No. The hardware is blank without bay‑configuration, protection‑setting parameters and logic scheme. Must download project configuration via PCM600 software, verify setting‑groups and GOOSE‑links before energizing.
A3: Check Ethernet‑cable link status, network‑switch HSR ring health, IED time‑synchronization status, access‑point setting, PCM600 downloaded GOOSE configuration consistency, and peer‑IED online‑status.
A4: Modules support mechanical hot‑swap, but REC670 executes critical bay‑control and breaker‑failure protection. Follow substation safety‑procedure; isolate related bay‑control‑power and block tripping‑output before module replacement.
A5: Anti‑static wrist‑strap mandatory for plug‑in‑module replacement. Avoid mechanical shock impact. Store in dry low‑humidity substation‑grade environment; keep original anti‑static packaging for spare‑part preservation.
