Description:

The ABB 3BHE031197R0001 is a specialized and highly robust Medium Voltage (MV) Wind Turbine Converter, a core component of ABB’s advanced PCS 6000 series. It is often referred to interchangeably with “GBU72” or other internal ABB part numbers like 3BHE055094R0002. This full-power converter is specifically designed to maximize energy capture and grid integration for large wind turbines, especially in demanding offshore wind farm applications, but also applicable to other high-power renewable energy sources like tidal and wave energy. It utilizes cutting-edge IGCT (Integrated Gate-Commutated Thyristor) technology and a modular design to achieve high efficiency, exceptional reliability, and low losses.

Application Scenarios:

Consider a modern offshore wind farm, a significant investment in renewable energy. These farms face unique challenges, including harsh marine environments, the need for high-efficiency power conversion, and stringent grid code compliance. The ABB 3BHE031197R0001 is deployed as the crucial interface between the wind turbine generator and the main power grid. For example, a single wind turbine with a capacity of 10 MW or more would utilize this converter. It receives the variable frequency AC power from the turbine’s generator (which changes with wind speed) and converts it into stable, grid-compliant AC power at the required voltage and frequency. Its fault ride-through capability ensures that the wind turbine remains connected to the grid even during significant grid disturbances (like voltage sags or swells), preventing costly disconnections and maximizing energy output. Furthermore, its dynamic braking chopper helps manage sudden power surges or grid interruptions, ensuring a smooth and safe shutdown when necessary. This crucial role makes the 3BHE031197R0001 indispensable for the stable, efficient, and reliable operation of large-scale wind power generation.

Technical Principles and Innovative Values:

The ABB 3BHE031197R0001 embodies sophisticated technical principles and offers substantial innovative values in renewable energy conversion:

• Full Power Conversion with IGCT Technology: At its core, the converter employs a full-power conversion topology, meaning it converts 100% of the generator’s output power. This is achieved through advanced IGCT (Integrated Gate-Commutated Thyristor) technology. IGCTs combine the high power handling and low conduction losses of thyristors with the fast switching speeds and simplified gate drive of IGBTs. This results in superior efficiency (near 98%) and reliability, significantly reducing energy losses compared to partial converters.
• Modular and Redundant Design: The 3BHE031197R0001 features a highly modular design with a minimal component count. This modularity allows for easy customization, simplified maintenance (e.g., hot-swappable power modules), and improved reliability through redundancy. If a module fails, it can often be replaced quickly without prolonged downtime, ensuring high availability of the wind turbine.
• Advanced Grid Code Compliance and Ride-Through Capabilities: A key innovation is its robust fault ride-through (FRT) capability, including Low Voltage Ride-Through (LVRT) and High Voltage Ride-Through (HVRT). This means the converter can keep the wind turbine connected to the grid and continue generating power even during significant grid voltage fluctuations or faults, crucial for grid stability and compliance with modern grid codes. It also includes features like dynamic braking choppers for controlled shutdown and overspeed/overvoltage protection.
• Intelligent Control with AC 800PEC: The converter is powered by ABB’s high-performance AC 800PEC controller. This advanced control platform enables sophisticated algorithms for maximum power point tracking (MPPT), optimal active and reactive power control, and seamless grid synchronization. It ensures that the wind turbine operates at peak efficiency regardless of wind speed and provides essential grid support services.
• Environmental Benefits: By reducing power transmission system losses and often eliminating the need for expensive, long cable lines through optimized installation (nacelle or tower), the 3BHE031197R0001 contributes to overall energy saving and reduced carbon emissions, aligning with sustainable development goals.

Application Cases and Industry Value:

In a rapidly expanding offshore wind farm in the North Sea, the operator faced challenges with grid stability and intermittent power generation due to fluctuating wind conditions and strict grid connection requirements. The existing converters were causing frequent disconnections during grid events. The solution involved replacing the legacy converters with the ABB 3BHE031197R0001 (PCS 6000) medium voltage wind turbine converters.

During a significant grid voltage dip caused by a distant transmission line fault, the ABB 3BHE031197R0001 converters demonstrated their superior fault ride-through capabilities. Instead of disconnecting, they maintained grid connection and continued to provide reactive power support, stabilizing the local grid. This significantly reduced downtime for the wind turbines and ensured continuous power delivery. Post-implementation, the wind farm reported a 15% increase in annual energy production due to improved efficiency and reduced disconnections. Furthermore, the modular design simplified maintenance operations in the challenging offshore environment, leading to a 25% reduction in maintenance costs and increased technician safety. This case exemplifies how the ABB 3BHE031197R0001 delivers immense industry value by maximizing renewable energy output, enhancing grid reliability, and reducing operational expenditure in critical offshore wind power generation.
