Description

The Woodward 9907-018 is a forward-acting electronic load sharing and speed control module from the 2301A series. This unit is engineered to manage the speed and load sharing of prime movers, including diesel engines, gasoline engines, and steam or gas turbines. It is widely utilized in power generation systems where multiple generator sets must operate in parallel, ensuring stable frequency and effective load distribution.

Features

Forward-acting speed control logic.
Supports both isochronous and droop control modes.
Compatible with diverse prime movers: diesel, gas, steam, and turbine systems.
Front-accessible potentiometers for field calibration and adjustment.
Automatic fuel limiting capabilities for controlled start-ups.
Designed for integration into isolated bus or infinite bus power systems.

Applications

Generator Set Control: Facilitates load sharing and precise speed regulation for parallel gensets.
Industrial Drive Systems: Maintains constant speed for pumps, compressors, and rock crushers.
Marine Power Systems: Manages generator synchronization and load management in shipboard environments.
Prime Mover Management: Provides reliable control for various engine and turbine configurations.

Technical Specifications

Model	9907-018
Series	2301A
Input Voltage	18–40 V DC
Speed Stability	+/- 0.25% of rated speed
Load Sharing Deviation	+/- 2% of rated power
Actuator Output	Max 2 A
Speed Feedback Range	50 Hz – 10 kHz (Selectable ranges)
Operating Temperature	-40 degC to +85 degC

Installation Guidelines

Mounting: The unit is housed in a sheet-metal chassis intended for panel mounting. Ensure adequate ventilation to maintain operating temperatures within the specified range.
Wiring: Use twisted-pair shielded cables for all signal lines to minimize EMI.
Grounding: Connect cable shields only at the control end to the grounding lug located below Terminal 9. The opposite end should remain insulated to prevent ground loops.
Safety: Ensure the power supply is compliant with SELV (Safety Extra Low Voltage) standards. Always power down the system before inserting or removing the module.
Configuration: The speed range is factory-set for 2000–6000 Hz but can be adjusted via internal switches for specific application requirements.

FAQ

What is the primary function of the 2301A control?

The 2301A is designed to sense the speed of a prime mover, compare it to a reference, and adjust the fuel or steam mechanism via an actuator to maintain a constant speed and share load equally among parallel units.

What are the supported control modes?

It supports isochronous mode for constant speed operation and droop mode for speed control as a function of load, typically used when paralleling with an infinite bus.

How is the speed sensor connected?

The control accepts signals from a magnetic pickup (MPU). The input impedance is 100 to 300 ohms, and it accepts signals from 1.0 V AC minimum to 30 V AC maximum.
