ABB GRID BREAKER UNIT GBU72 3BHE055094R0002 Module
1.1 Product Name
ABB GRID BREAKER UNIT GBU72 3BHE055094R0002 Industrial Wind Farm Grid-Connection Breaker Control Module—— A dedicated control unit for wind farm grid connection, belonging to ABB’s wind energy auxiliary system portfolio. It specializes in “grid breaker status monitoring + safe on/off-grid control + fault protection coordination” and is matched with medium-voltage circuit breakers in 2MW-8MW wind turbines to ensure reliable grid connection/disconnection of wind power systems.
1.2 Product Description
The ABB GRID BREAKER UNIT GBU72 3BHE055094R0002 addresses core challenges in wind farm grid connection, such as unsafe breaker operation during voltage fluctuations, poor coordination with grid codes, and difficulty in remote status monitoring. Its key functions are as follows:
- Safe Grid On/Off Control: It serves as the “brain” for wind turbine grid breakers, receiving grid connection commands from the wind turbine controller (WTC) and executing breaker closing/opening operations with a response time of ≤200ms. It integrates pre-closure grid quality detection (voltage deviation ≤±5%, frequency deviation ≤±0.5Hz) to avoid inrush current damage to the grid and turbine.
- Real-Time Status Monitoring & Fault Protection: Equipped with 8-channel analog input (for grid voltage, current, breaker temperature) and 16-channel digital input (for breaker auxiliary contact status, lockout signals). It monitors breaker operation status in real time (e.g., contact wear, mechanical jamming) and triggers protection actions (e.g., emergency opening) within ≤100ms if faults like overcurrent (120% rated current) or overvoltage (110% rated voltage) occur.
- Grid Code Compliance: Complies with global wind farm grid codes (IEC 61400-21, IEEE 1547) by supporting low-voltage ride-through (LVRT) coordination—when grid voltage dips, it maintains breaker closure to keep the turbine connected (sustains 0% voltage dip for 150ms) and disconnects only when grid recovery is impossible, avoiding unnecessary off-grid events.
- Remote Integration & Harsh Environment Adaptability: Supports Modbus TCP/DNP3 communication protocols, enabling data interaction with wind farm SCADA systems (e.g., ABB Ability™ Wind Power Management) for remote breaker control and fault diagnosis. Adopting a compact, corrosion-resistant housing (IP54 protection), it operates stably in -30℃~+50℃ (onshore) / -20℃~+45℃ (offshore) environments, resisting salt spray (IEC 60068-2-52) and vibration (10-50Hz, ≤0.5g).
This module is widely used in onshore/offshore wind farms, acting as a critical link between wind turbines and the grid to ensure safe, compliant, and efficient grid connection operations.
