3. Detailed Product Description

In the realm of industrial power generation and mechanical drive applications, maintaining consistent speed and accurately sharing loads among multiple prime movers are crucial for efficiency, stability, and equipment longevity. Imagine a power plant where generators must operate seamlessly in parallel, or a gas compressor driven by a turbine that needs precise speed regulation under varying loads. This is where the WOODWARD 9907-2024 steps in, offering a time-tested and reliable solution for sophisticated prime mover control.

The WOODWARD 9907-2024 is a core component within the venerable Woodward 2301A series, a family of electronic controls renowned for their durability and performance in demanding environments. This particular model excels at providing precise control over the speed and load of engines and turbines, making it an indispensable asset for critical power generation and industrial applications. Its robust design, encapsulated in a sturdy sheet-metal chassis, ensures reliability even when faced with the rigors of industrial operations.

Key Features and Benefits

Versatile Speed and Load Control: The primary function of the WOODWARD 9907-2024 is to meticulously control the speed of prime movers and facilitate efficient load sharing. Whether you’re dealing with a standalone engine driving a pump or multiple generators synchronized to a grid, this module provides the precision needed to maintain optimal operating conditions. It’s particularly well-suited for complex setups involving engines isolated with torque converters and split shaft gas turbines, where dynamic control is paramount.

Selectable Control Modes (Isochronous & Droop): The 9907-2024 offers critical flexibility through its selectable control modes:

• Isochronous Mode: Ideal for single-prime-mover operations or when a constant speed is desired regardless of load changes. This mode ensures the prime mover maintains a precise speed, providing a stable frequency for generators.
• Droop Mode: Essential for parallel operation of multiple generators or prime movers. This mode allows for a controlled speed drop as load increases, facilitating stable load sharing among units without hunting or instability.

Robust and Field-Proven Design: As part of the 2301A series, the 9907-2024 is built for industrial longevity. Its compact design, featuring a single printed circuit board housed within a protective sheet-metal chassis, emphasizes durability. All adjustment potentiometers are conveniently accessible from the front, simplifying setup and maintenance.

Flexible Actuator Interface: The control module is designed to interface seamlessly with a proportional actuator. This actuator, in turn, precisely positions the fuel-metering device (like a fuel rack or valve), directly translating the electronic control signals into accurate mechanical adjustments to regulate the prime mover’s output.

Advanced Control Capabilities: Beyond basic speed and load control, the 9907-2024 includes advanced features to optimize prime mover performance:

• 4-20 mA or 1-5 Vdc Remote Speed Setting: Allows the prime mover’s speed or load to be set remotely via a process control signal or a computer, offering seamless integration into larger plant control systems.
• High and Low Speed Adjustments: Enables fine-tuning of operating limits to match specific application requirements.
• Start Fuel Limit with Override: Provides precise control over fuel delivery during startup, enhancing safety and preventing over-fueling, with an override option for specific operational needs.

Environmental Considerations: For optimal performance and longevity, it’s crucial to install the 9907-2024 in an environment free from excessive vibrations, moisture, high voltage interference, and electromagnetic interference (EMI). Its design is suited for closed industrial control cabinets.
