9907-076

Woodward 9907‑076 is a 2301A series electronic speed and load‑sharing governor, engineered for diesel/gas engines, steam/gas turbines and generator sets. It provides precise speed regulation, parallel load sharing, overspeed protection and fault monitoring for prime movers in power generation, petrochemical, oil‑gas and marine heavy‑duty industries.

Description

Core Functions

  1. Dual control modes: isochronous mode for single‑unit constant‑speed operation; droop mode for multi‑unit genset parallel load sharing.

  2. PID closed‑loop regulation with startup ramp control, actuator stroke limit and load rejection protection.

  3. Built‑in overspeed protection, real‑time self‑diagnosis and relay alarm outputs.

  4. 4‑20 mA analog remote setpoint input for integration with DCS/PLC systems.

  5. Standard forward‑acting control logic for fuel actuator driving.
