The ABB 3BHE022886R0001 (GV D241 A) is a specialized Power Interface Board primarily used in ABB's UNITROL excitation systems, specifically with the UN6080 series. It's a critical component for controlling and measuring parameters related to the power stage of synchronous machine excitation.

Product Description

The ABB 3BHE022886R0001, often identified by the product name GV D241 A or PIN6080, serves as the main interface between the CCM6080 (Control and Communication Module) and the power stage of the UN6080 excitation system. This board is a fully passive board, which means it relies on signals from other active control units.

3BHE022886R0101

Its core functions include:

• Voltage Measurement: It features high-voltage dividers to measure both the 3-phase synchronous voltage (Usyn) of the generator/motor and the DC converter output voltage (Udc) from the excitation rectifier.
• Current Measurement: It measures the converter synchronous current using burden resistors.
• Temperature Measurement: Routes a temperature signal from the converter part to the CCM6080, essential for thermal monitoring and protection.
• Thyristor Firing Pulse Generation: It is responsible for generating the precise firing pulses for the thyristors within the converter, directly controlling their switching.
• Snubber Circuit Interface: Provides an interface for an external snubber resistor, crucial for protecting the thyristors from voltage spikes during switching.
• Cooling Fan Supply Forwarding: Forwards the 24V supply voltage from the CCM6080 to the cooling fans of the converter.

Designed to be mechanically compatible with the SDCS PIN-4 board, it can replace it in certain DCS800 family converter cases, highlighting its robust and integrated design for high-power applications.

Product Application Cases

The ABB 3BHE022886R0001 (GV D241 A / PIN6080) is crucial in large-scale power generation and heavy industrial applications where precise and reliable excitation control of synchronous machines is essential.

• Power Generation Plants: This is its primary application. It's used in the excitation systems of large synchronous generators (e.g., in thermal, hydro, nuclear, and gas-fired power plants). It ensures that the generator's terminal voltage and reactive power output are precisely regulated, critical for maintaining grid stability, optimizing power factor, and preventing damage to the generator.
• Industrial Synchronous Motors: In heavy industries such as mining, metals, and cement, large synchronous motors are used for high-power applications like mill drives, large pumps, and compressors. The board within the excitation system precisely controls the motor's field current, optimizing its efficiency and power factor.
• Grid Stabilization and VAR Compensation: In utility applications, where flexible AC transmission systems (FACTS) or Static Synchronous Compensators (STATCOMs) utilize synchronous machines for voltage support and reactive power compensation, this board would be part of the control loop.

• Power System Interconnections: For connecting different power grids or integrating large renewable energy sources, synchronous condensers might be used for reactive power support, and this board would be fundamental to their operation.
