9907-018
Engineered for intelligent and efficient generator system management, the WOODWARD 9907-018 integrates core functions of speed regulation and load sharing, supporting two adjustable operation modes: droop control and isochronous control. The isochronous mode delivers zero-error constant speed control, ideal for standalone generator operation and isolated grid system scenarios, while the droop control mode provides flexible load distribution adjustment to adapt to complex multi-unit parallel operation conditions. In terms of system configuration, this module features high system compatibility and expandability, which can be seamlessly matched with Woodward’s supporting equipment such as automatic power transfer devices, I/O controllers, and generator load managers to build a complete integrated generator control system. Equipped with standard Modbus communication protocol, it supports real-time data transmission, remote parameter configuration, and operating status monitoring, enabling intelligent linkage with SCADA industrial control systems. Meanwhile, it has built-in overvoltage, overcurrent, and over-temperature protection mechanisms, which can automatically trigger protection responses in abnormal working conditions to effectively avoid equipment damage and ensure the safe and stable operation of the entire power generation system.
With its ultra-high control precision, strong environmental adaptability, and excellent system compatibility, the WOODWARD 9907-018 is widely applied in multi-unit generator sets and various industrial power generation scenarios, serving as a core control component for stable power system operation. Its main application fields cover industrial factory backup power generation systems, commercial building emergency power units, offshore engineering power generation equipment, distributed power stations, and diesel generator parallel grid-connected systems. In addition, it is perfectly suitable for isolated power grid operation scenarios in remote mining areas, construction sites, and marine vessels, effectively solving unstable load distribution and speed fluctuation problems during multi-generator parallel operation. It can also be used in intelligent power plant monitoring and energy management systems, providing accurate data support and precise control guarantee for industrial power intelligent operation, greatly improving power supply stability and energy utilization efficiency.
