ABB PPD513AOC-100440 3BHE039724R0C3D AC800PEC Excitation Controller – Key Functions
1. High-Performance Excitation Control
Implements advanced control algorithms to regulate generator field current with ±0.25% voltage accuracy, ensuring stable terminal voltage under dynamic loads.
Supports dual-mode operation: Automatic Voltage Regulator (AVR) and Field Current Regulator (FCR) for flexible grid compliance.
2. Ultra-Fast Response for Grid Stability
Achieves 100μs control cycle times via FPGA-based processing, critical for transient stability during faults.
Integrates adaptive Power System Stabilizer (PSS) to dampen low-frequency oscillations (<2Hz).
3. Modular & Robust Architecture
Part of ABB’s AC800PEC system, featuring fiber-optic communication between controllers and I/O modules for EMI immunity.
Industrial-grade design with -40°C to +70°C operational range and SIL2 safety certification.
4. Cyber-Physical Integration
Compatible with ABB Ability™ 800xA for plant-wide monitoring and IEC 61850 for substation automation.
Supports MATLAB/Simulink® for model-based control development and real-time simulation.
5. Protection & Diagnostics
10+ protection functions including over/under excitation, V/Hz limits, and rotor earth fault detection.
Predictive maintenance via rotor thermal modeling and harmonic analysis (up to 50th order).
6. Typical Applications
Black-start capable excitation for thermal/hydro generators.
Renewable integration (inertia emulation in wind/solar farms).
Industrial megawatt-scale rectifiers (e.g., aluminum smelters).
