ABB KUC711AE101 Excitation Control System – Key Functions
The ABB KUC711AE101 (3BHB004661R0101) is an advanced excitation controller for power generators.
Its main roles are:
1. Voltage Control
Maintains stable generator output voltage by adjusting field current.
Works in AVR (Auto Voltage Regulator) or manual mode.
2. Grid Stability
Includes Power System Stabilizer (PSS) to reduce power oscillations.
Supports reactive power (VAR) control for better grid synchronization.
3. Protection & Monitoring
Prevents over/under-voltage, overcurrent, and loss-of-field faults.
Provides real-time diagnostics via IEC 61850, Modbus, or DNP3.
4. High Reliability
Redundant design for fail-safe operation in power plants.
Industrial-grade hardware for harsh environments.
5. Applications
Thermal/hydro plants, wind farms, industrial generators.
