POM72 3BHE051397R0101 Other Names:
PCS 6000 System Full Power Converter POM72 3BHE051397R0101
POM72 3BHE051397R0101 PCS 6000 System Medium Voltage Wind Turbine Converter
PCS 6000 System Medium Voltage Converter POM72 3BHE051397R0101
ABB’s core grid circuit breaker unit POM72 3BHE051397R0101 is designed specifically for large wind turbines, featuring a low component count, high availability, and minimized losses. The higher voltage rating of medium-voltage converters means lower currents in the power transmission system, making them easier to integrate into wind turbines. These converters can be designed for nacelle or tower installation, and their modular design allows for easy customization to meet customer needs. They also feature fault ride-through and grid compliance capabilities.
System Affiliation: The POM72 3BHE051397R0101 is a core component of ABB’s PCS6000 medium-voltage power conversion system. As a grid breaker unit (GBU), it performs grid connection, power control, and system protection functions.
Core Functions:
Grid Control: Implements grid-side circuit breaker closing/opening, grid synchronization, power distribution, and fault isolation, ensuring safe system startup and shutdown, and continuous operation.
Circuit On/Off Control: Enables intelligent connection/disconnection between the grid and the drive system, supporting grid synchronization and power distribution.
Protection Mechanisms: Integrated overload, short-circuit, undervoltage, and overvoltage protection functions. Rapid shutdown (response time <1μs) and arc extinguishing technology limit short-circuit current peaks, improving grid stability.
Communication Coordination: Supports fiber optic, PROFIBUS DP, Modbus RTU, and other interfaces, enabling efficient communication with host controllers (such as the AC 800PEC), HMIs, and remote I/O modules.
Multiple Protection Mechanisms: Integrated overload, short-circuit, undervoltage, and overvoltage protection with a response time <1μs. Advanced arc extinguishing technology limits short-circuit current peaks, improving system stability.
Arc Extinguishment: Advanced arc extinguishing technology limits short-circuit current peaks, improving system stability.
Communication Interface: Communicates with a host controller (such as the AC 800PEC) via fiber optic cable and supports MODBUS or custom protocols, enabling remote monitoring and parameter configuration.
Expandability: By adding I/O modules (such as the GFD563A102) or communication interfaces (such as PROFIBUS DP and Modbus RTU), the system can adapt to project needs of varying sizes and support system upgrades and functional expansion.

Application Scenarios and System Integration
Typical Applications:
Industrial Drives: Control of high-power motors in metallurgical rolling mills, mining machinery, and cement plants, compatible with ACS6000 medium-voltage inverters.
Renewable Energy: Synchronize power conversion with the grid in wind turbine converters and photovoltaic inverters, supporting low-voltage ride-through (LVRT).
Rail Transit: Control of subway traction converters and port cranes, ensuring high-reliability operation.
Infrastructure: Power grid protection systems and data center power management, enabling power outage protection and system interlocking.
System Collaboration:
Commonly works with ABB PM891/PM861 master control modules, IGCT modules (such as 3BHB030310R0001), 3BHE055094R0002 (power modules), and power modules (such as PS907W) to form a complete power conversion and control system.
Installation and Maintenance Key Points
Installation Requirements:
Installation must be performed in a control cabinet environment with a temperature range (-20°C to +70°C) and humidity range (<80% RH non-condensing). Ensure the backplane is compatible and the power module is properly connected.
Before installation, use an anti-static wrist strap to prevent static electricity from damaging the module’s internal components. An aluminum alloy heat sink is recommended to maintain the junction temperature below 100°C.
Maintenance Specifications:
Regularly check the control cabinet’s heat dissipation. Use ABB Control Builder software to monitor module status, log information, and communication status.
When replacing or upgrading a module, power must be disconnected. Current program and configuration parameters must be recorded. Firmware upgrades and system calibration are supported (recommended every two years).
Summary
The POM72 3BHE051397R0101 , the core grid circuit breaker unit in the ABB PCS6000 system, is a core component in industrial automation and power control. Its high reliability, redundant configuration, and multi-protocol communication capabilities make it an ideal choice for high-power industrial drives, energy management, and critical process control.
