Product Overview

The Woodward 9907-018 (2301A) is a high-precision electronic controller designed for load sharing and speed synchronization in industrial power systems. It manages diesel engines, gas engines, steam turbines, and gas turbines in both standalone and parallel configurations. The unit provides a critical interface between speed sensors and proportional actuators, ensuring stable system frequency under dynamic load conditions.

Technical Specifications

Engineering Advantages

Isochronous and Droop Control
Supports both isochronous mode (constant speed) and droop mode for effective grid synchronization or island operation.

High-Resolution Actuator Drive
Provides a 0–200 mA output signal for precise actuator control, ensuring smooth response and minimizing speed instability during load changes.

Integrated Load Sharing
Automatically balances load across multiple generators in parallel operation, preventing overload and reverse power conditions.

Wide Voltage Tolerance
Operates within a 20–40 VDC range, ensuring reliability in standard 24 VDC systems even during voltage fluctuations.

Compact Design
Low-profile (2.5" depth) and lightweight construction allow easy installation in space-constrained or high-vibration environments.

FAQs

What types of prime movers does the 9907-018 support?
Compatible with diesel engines, gas engines, steam turbines, and gas turbines using appropriate sensors and actuators.

Does this unit require a separate load sensor?
No. It typically uses internal CT/PT inputs to directly measure generator load.

How do I calibrate the speed settings?
Front-panel potentiometers allow manual adjustment of speed, gain, reset, and load-sharing parameters without external software.

Can this module replace older 2301 series units?
Yes. The 2301A is an enhanced version, but wiring and voltage compatibility should be verified before replacement.
