FUNCTIONAL DESCRIPTION:

IS200EDFFH1AAA is an Exciter DC Fanned Feedback Board manufactured and designed by General Electric and is part of the EX2100e Series used in Excitation turbine control systems. The component features a dual system setup that improves its performance and redundancy. For smooth functionality, the board requires a fiber-optic connection, which provides voltage isolation between the EAUX and EDFF boards. This isolation enhances safety and significantly reduces noise interference. The model consists of three separate groups, each designed to meet specific system needs. The H2 group, to which this component belongs, operates within a dual system configuration, boosting its capabilities and overall reliability.

FUNCTIONS:

• Voltage Regulation: The Exciter DC Fanned Feedback Board regulates the excitation voltage to the generator's field winding, ensuring a stable output voltage. It adjusts the excitation current to maintain the desired generator performance and efficiency.

• Feedback Control: The board processes feedback signals from the exciter's DC supply to compare the actual voltage with the desired reference. It then adjusts the excitation voltage to keep the generator's output stable.

• Redundancy and Safety: The board ensures safety through voltage isolation using fiber-optic links, preventing electrical faults from spreading. The dual-system design enhances redundancy, ensuring continuous operation if one system fails.

• Cooling (Fanned Design): A fan-based cooling system dissipates heat generated by the board, maintaining safe operating temperatures. This prevents overheating and ensures reliable performance, especially under high-load conditions.

• Noise Immunity: The use of fiber-optic links minimizes electromagnetic interference, ensuring clean signal transmission. This noise immunity helps maintain accurate feedback and stable voltage regulation.

• System Monitoring and Protection: The board continuously monitors the exciter’s performance, adjusting excitation levels to protect against faults. It triggers protective actions if anomalies, like voltage spikes or drops, are detected.

• Dual System Configuration (H2 Group): Operating within a dual system framework, the board provides redundancy for enhanced fault tolerance. This configuration ensures that one system can take over if the other fails, maintaining continuous operation.
