Woodward 9907-252 Steam Turbine Speed ​​Controller Module

Product Dimensions：

The Woodward 9907-252 is a high-performance 2301A Load Sharing and Speed Control unit. It is designed specifically for controlling induction motors and engines, providing precise speed and load management in power generation and industrial applications.

1. Product Detailed Description

The 9907-252 is part of the legendary 2301A series. Its primary function is to regulate the speed of a prime mover (engine or turbine) and manage how that unit shares its electrical load when paralleled with other units or the main utility grid.

It operates by sensing the speed of the engine via a magnetic pickup (MPU) and comparing it to a setpoint. It then sends a proportional signal to an actuator to adjust fuel or steam delivery.

3. Product Advantages

• Precision Control: Offers excellent stability and transient response, ensuring the system recovers quickly from sudden load changes.

• Reverse Power Protection: Built-in logic helps prevent the generator from being driven by the grid (motoring).

• Isochronous & Droop Modes: Flexible operation allows for standalone precision (isochronous) or grid-parallel stability (droop).

• Proven Reliability: The 2301A architecture is “bulletproof,” known for decades of service life in harsh environments.

• Simple Setup: Unlike modern digital controllers that require complex software, this analog unit is tuned using straightforward potentiometers.

4. Safety Precautions & Warnings

Caution: Incorrect wiring of the load sharing lines can cause significant system instability or “hunting.”

• Proper Grounding: Ensure the chassis and shielded cables are grounded correctly to prevent EMI (Electromagnetic Interference).

• Magnetic Pickup (MPU): The MPU must be mounted with the correct air gap. If the signal is too weak, the controller will fail to sense speed.

• Actuator Compatibility: Verify that the 0–200 mA output matches your specific actuator requirements before powering on.

• Live Tuning: Use insulated tools when adjusting potentiometers while the engine is running to avoid accidental shorts.

5. Product Applications

The Woodward 9907-252 is a versatile controller used in various sectors:

• Power Plants: Parallel operation of multiple diesel or gas generator sets.

• Marine Vessels: Managing main propulsion engines or auxiliary power systems.

• Industrial Facilities: Peak shaving and emergency standby power systems.

• Oil & Gas: Controlling turbines and engines used in remote pumping stations.
