Product Features
WOODWARD 9907-014 features dual-mode control, redistribution function, dynamic adjustment function, safety protection and extended compatibility.
Dual-mode control: WOODWARD 9907-014 supports isochronous and droop modes
Isochronous mode: maintains a constant speed, suitable for single units or multiple units in isolation (load control accessory required).
Droop mode: the speed varies with the load (the speed decreases as the load increases) and is suitable for parallel connection to an infinite grid or for parallel operation of several units.
Load distribution function:
The generator load is detected by current transformer (CT) and voltage transformer (PT), and the internal load matching circuit realizes the proportional distribution of load among multiple units to ensure the load balance during parallel operation.
Dynamic adjustment function:
GAIN, RESET and ACTUATOR COMPENSATION knobs can be adjusted to optimize the dynamic response of the unit (e.g. speed stability during sudden load changes). WOODWARD 9907-014 supports START FUEL LIMIT and RAMP TIME adjustment to avoid speed overshoot or smoke during startup.
Safety Protection:
integrated speed signal failure detection circuitry automatically places the actuator in the minimum fuel position when the speed sensor signal is lost (requires external emergency stop). WOODWARD 9907-014 supports external fault signal override for temporary bypass of speed signal detection at startup.
Extended compatibility:
External speed trimmer potentiometer, SPM-A synchronizer and other accessories can be connected to support remote speed adjustment and synchronization of the unit with the grid.
Product Application
WOODWARD 9907-014 is suitable for power generation systems that require precise speed control and parallel load distribution, typical scenarios include:
Diesel / Gas Gensets:
WOODWARD 9907-014 stable operation of a single unit (synchronous mode) or parallel power supply of multiple units (sag mode), e.g., data center backup power, remote area microgrid.
Marine Power Systems:
WOODWARD 9907-014 drives marine generators to ensure load balancing and maintain grid stability when multiple units are in parallel.
Industrial power station:
WOODWARD 9907-014 steam turbine or gas turbine-driven generator control for self-supply power station in chemical industry, metallurgy and other industries.
Emergency Power System:
WOODWARD 9907-014 works with automatic transfer switch (ATS) to realize seamless switching between utility power and generator to guarantee power supply to critical loads.
