Product Introduction
The ABB GBU72 3BHE055094R0002 represents ABB’s ultimate grid protection solution – a high-speed DC uninterruptible power system engineered specifically for mission-critical circuit breaker control. This integrated system combines the main power conversion unit (3BHE055094R0002), matched battery cabinet (3BHE031197R0001), and optional redundancy module (3BHB030310R0001) to ensure absolute reliability in transmission substations and generator installations. The GBU72 system delivers zero-interruption power to protective relays and breaker trip coils during grid disturbances, preventing catastrophic blackouts.
Designed for compliance with NERC CIP standards, this solution features hardware-encrypted communications and tamper-proof enclosures. The ABB GBU72 ecosystem maintains 72V DC power with <1% ripple even during battery mode, ensuring precise operation of ABB REF615 relays and similar protection devices. Its modular architecture allows scalable runtime from 30 minutes to 8 hours through parallel battery strings, making it the cornerstone of modern grid resiliency strategies.
Core Advantages and Technical Highlights
Grid-Fault Survival:
The GBU72 3BHE055094R0002 withstands 100% voltage collapse for 200ms without transfer to batteries. Dual IGBT inverters with phase-synchronized switching ensure <500μs transfer during complete blackouts – critical for maintaining zone protection schemes.
Cybersecurity by Design:
Implements hardware-based key management compliant with IEC 62443-3-3 SL3. Runtime firmware validation using SHA-256 hashing prevents malicious code injection. All communication ports feature configurable ACLs (Access Control Lists).
Adaptive Grid Harmonization:
Proprietary Active Harmonic Filtering reduces THDi to <5% even with nonlinear loads. Automatic generator synchronization minimizes transfer shock during grid restoration. The 3BHB030310R0001 redundancy module enables seamless module replacement without load disruption.
Extreme Environment Operation:
Cold-start capability at -40°C with battery heaters automatically engaged below -15°C. IP42-rated cabinets with corrosion-resistant coatings withstand coastal salt spray and desert sandstorms.

Typical Application Scenarios
In 500kV substations, the ABB GBU72 3BHE055094R0002 sustains differential protection relays during cascading failures, enabling selective breaker tripping to contain grid disturbances. Its 3.5kVA pulse power capability simultaneously energizes multiple 125V DC trip coils for bus-section isolation.
For offshore wind farms, the system provides ride-through capability during collector grid faults. The 3BHE031197R0001 battery cabinet’s seismic design (IEC 60068-3-3) maintains STATCOM control during turbine-induced vibrations. In hydroelectric plants, the GBU72 executes black-start sequences by powering excitation systems when grid power is lost, with runtime extendable to 4 hours through parallel battery strings.
