Woodward 9907-018 2301A Load Sharing and Speed Control

The Woodward 9907-018 2301A is an electronic control device developed for full authority speed and load management applications.

The controller receives speed signals from the engine sensing system and adjusts actuator output to maintain stable engine speed. In generator applications, it can operate in isochronous or droop modes, allowing flexible operation for both single-unit systems and multiple generator configurations.

The unit includes load sharing capability through generator current sensing and can coordinate power distribution between multiple generator sets operating on the same electrical bus. Its adjustable parameters allow technicians to tune system response, including gain, compensation, and fuel control characteristics.

The 9907-018 is designed for retrofit projects, generator control upgrades, and industrial applications where dependable speed control performance is required.
