What controls all functions of the BPU's electrical generation, through the Automatic Voltage Regulator logic, and interfacing with the Engine Control Modules (ECM)?

• A. Mechanical governor
• B. Digital control system
• C. Analog controller
• D. Remote interface module

Answer: (B)

The centralized digital control system serves as the brain that governs the BPU’s electrical generation, running the Automatic Voltage Regulator logic and coordinating with Engine Control Modules. It continuously samples generator voltage and frequency, compares them to reference values, and uses software-based AVR algorithms to adjust excitation. That excitation control stabilizes the terminal voltage as load changes. At the same time, it talks to the ECMs to align engine speed, fuel, and other aspects of the mechanical side with the electrical output, ensuring proper synchronization, protection, and coordinated response across the system. A mechanical governor operates with physical, non-electronic feedback and doesn’t manage the full range of modern generation control, so it’s not best for integrated AVR and ECM interaction. An analog controller would handle the AVR with hardware circuitry but lacks the flexibility and seamless ECM communication of a digital system. A remote interface module handles communication pathways but doesn’t control all generation functions.
