Woodward 9907-1324 Electronic Speed Control Controller

Product Description

Woodward 9907-1324 is an electronic load sharing and speed governor controller of Woodward 2301A series, designed for generator paralleling systems. The 2301A is a classic analog governor with isochronous / droop control modes, multi-unit load sharing, start fuel limit and acceleration/deceleration ramp functions. It receives MPU magnetic pickup speed signal and outputs 0–200mA to drive the actuator, no actuator position feedback required. Built-in load sensing circuit, forward / reverse acting available. It stabilizes speed and distributes load for diesel, gas engine and small steam turbine generator sets. This model is discontinued by original manufacturer and supplied as spare part for power plant control system maintenance.

Product Application

It is deployed on diesel generator sets, gas generator sets and small steam turbine generator sets for single-unit speed stabilization and balanced load distribution after paralleling. It measures real-time engine speed, compares with speed setpoint and outputs current signal to fuel actuator to adjust fuel supply. It supports generator paralleling, decoupling, soft loading and unloading to avoid unit overload or overspeed. Widely used in captive power stations, oil & gas field power plants, marine power stations and emergency backup generators. It serves as critical governor spare part for legacy paralleling power generation systems.
