Woodward 9907-018 Load Sharing And Speed Control

Technical Overview

The 9907-018 is a high-precision electronic control module from the renowned Woodward 2301A series. This unit is engineered to provide deterministic speed regulation and proportional load sharing for a wide array of prime movers, including diesel and gasoline engines, as well as steam and gas turbines. By integrating a self-contained load sensor, the 9907-018 eliminates the need for external sensing hardware, simplifying the control architecture in multi-generator or multi-engine power plants.

Designed for high-reliability applications, the 9907-018 ensures balanced load distribution across parallel-operating units, preventing engine hunting and optimizing fuel efficiency. Its ruggedized internal circuitry is shielded against electromagnetic interference (EMI) and radio frequency interference (RFI), making it suitable for installation in environments with high electrical noise.

Application and System Deployment

The 9907-018 is a critical component in microgrid management and industrial power generation. It is frequently utilized in marine propulsion systems, standby power stations, and turbine-driven mechanical drives. The unit’s ability to interface directly with Woodward’s legacy and modern actuators makes it an ideal choice for both new installations and the modernization of existing governor systems. Its "all-in-one" load sensing capability allows for a more compact control cabinet footprint while maintaining laboratory-grade precision in speed governing.
