Product Advantages and Features

Triple Modular Redundancy (TMR): Operates in a 2-out-of-3 (2oo3) voting logic. This ensures that a single module failure will not cause a nuisance trip or a failure to trip.

On-Line Repair: The modular design allows a single module (like the 5437-1067A) to be replaced while the turbine is running, significantly reducing plant downtime.

Acceleration Protection: Unlike basic overspeed trips, it calculates the rate of speed change (acceleration) to predict and prevent overspeed before it happens.

Integrated Logging: Maintains internal logs for the last 50 trips/alarms and 20 overspeed events with high-resolution timestamps.

Ruggedized Construction: Features sulfur-resistant conformal coating, making it suitable for Class 3C2 corrosive environments.

Introduction

The Woodward 8440-1706 (SPM-D11) is a robust, microprocessor-based synchronizer that eliminates the human error associated with manual generator paralleling.

7 By continuously monitoring the voltage and frequency of both the generator and the utility bus, it issues corrective commands to the engine’s governor and voltage regulator.

Once the generator is perfectly “in phase,” the SPM-D11 triggers the circuit breaker, ensuring a smooth transition of power.

It is highly valued for its reliability in critical infrastructure where even a minor synchronization error could result in significant equipment damage.

The Woodward 5466-425​ delivers critical performance through its closed-loop servo control system.

The core of its operation involves comparing the valve’s actual position (measured by the integrated LVDT/RVDT) to the desired position commanded by the turbine controller.

Any difference (error) between these two signals is amplified and used to drive the actuator—either by porting hydraulic fluid to a piston (in an electro-hydraulic design) or by turning a motor (in a direct drive design).

This continuous correction ensures the valve spool or poppet is positioned with extreme accuracy, resulting in precise fuel flow metering
