Main Functions

1. Core real‑time excitation control algorithm execution：Run AVR automatic voltage‑regulation logic, reactive‑power / power‑factor closed‑loop control, excitation‑limiter function and multiple‑set parameter switching logic for synchronous generator.
2. Excitation protection and sequence logic processing：Complete over‑excitation, under‑excitation, loss‑of‑field, over‑current protection calculation; handle cabinet startup‑stop sequence, field‑breaker control interlock logic.
3. System‑wide data coordination：Interact with measurement board, pulse driver board, communication board via back‑plane bus; receive sampling data, send firing‑pulse commands, forward operating data and alarm events.
4. Parameter storage and fault waveform recording：Store project configuration parameters locally; capture fault snapshot, event log and disturbance recording waveforms for post‑accident analysis.
5. Hardware watchdog self‑monitoring：Built‑in hardware watchdog circuit; trigger safety pulse‑blocking protection when CPU runs abnormally to avoid uncontrolled excitation output.
6. Comprehensive self‑diagnosis function：Detect firmware exception, memory failure, back‑plane bus communication error. Fault codes are generated and uploaded to local HMI and remote DCS alarm system.
7. On‑board multi‑LED status indication
   • Green LED：Board 24 V auxiliary power supply normal, CPU running healthy
   • Yellow LED：Back‑plane bus data transmitting / receiving active
   • Red LED：CPU fault / bus communication failure / hardware error

Installation & Wiring Requirements

1. Insert board into standard Euro‑card cabinet slot, lock front‑panel handles; ensure back‑plane gold‑finger connector fully engaged. Hot‑swap is strictly forbidden; cut off cabinet total power before disassembly and assembly.
2. Ensure cabinet ventilation and heat dissipation; avoid conductive dust and corrosive gas accumulating on PCB surface.
3. Cabinet protective grounding must strictly follow ABB UNITROL6000 system grounding specification to guarantee anti‑interference capability.
4. Verify 24 V DC logic power supply within allowable tolerance; over‑voltage will cause permanent hardware damage.
5. After replacement, download matching firmware and project parameters; perform overall control‑loop commissioning test.
