Description

WOODWARD 2301A 9907-018 Load Sharing & Speed Control Documentation

1. Product Overview

The WOODWARD 2301A 9907-018 is a forward-acting speed control module designed for diesel, gas engines, and turbines. It enables precise regulation of speed or load based on 4–20 mA or 1–5 Vdc signals from process systems or computers. Ideal for power generation, oil and gas, and marine applications, the 9907-018 supports isochronous (constant speed) or droop (variable speed) control modes, ensuring stable operation in both standalone and multi-unit generator systems.

3. Advantages and Features

Precision Control:
- Isochronous mode maintains constant speed for isolated grids; droop mode allows load sharing in parallel systems.
- High-accuracy algorithms ensure ±0.1% speed regulation.
Integration Flexibility:
- Built-in signal converter eliminates external hardware.
- Compatible with Woodward’s SPM-A synchronizers, load sensors, and auxiliary controls.
Reliability:
- EMI/RFI shielding and rugged metal chassis protect against harsh environments.
- CE/CSA certifications guarantee safety and compliance.
User-Friendly Design:
- Front-accessible potentiometers simplify setup.
- Automatic start fuel limit reduces engine wear and emissions.

4. Application Areas and Use Cases

Power Generation: Synchronizing generators in thermal, hydro, and gas turbine plants.
Oil & Gas: Controlling pumps and compressors in offshore platforms.
Marine: Optimizing power distribution in shipboard systems.

Case Study: A European power plant reduced synchronization errors by 25% using the 9907-018, improving grid stability and operational efficiency.

5. Competitive Comparison

The 2301A 9907-018 outperforms alternatives with:

Dual-Mode Operation: Combines isochronous and droop control in a single unit.
Compact Design: Space-saving layout ideal for retrofitting.
Cost-Effective Maintenance: Modular components reduce downtime.

6. Selection Recommendations

Voltage Compatibility: Choose low or high voltage models based on system requirements.
Actuator Type: Verify compatibility with Woodward EG, PB, or TM actuators.
Environment: Opt for IP-rated enclosures in dusty or humid settings.

7. Precautions

Installation: Avoid mounting on engines; ensure adequate ventilation and vibration isolation.
Calibration: Regularly test load sensors and potentiometers.
Software Updates: Use Woodward’s official tools for firmware upgrades.
