Description
The Woodward 2301A Load Sharing Speed Control 9906-018 is an electronic generator control module designed for prime mover speed regulation and generator load sharing applications. It provides speed control, load sharing, and actuator control functions for diesel engines, gas engines, steam turbines, and gas turbines used in power generation systems. The 2301A series controls generator output by monitoring engine speed and generator load conditions, allowing multiple generators operating in parallel to share load proportionally.
The 9906-018 model is part of the Woodward 2301A Load Sharing & Speed Control family and is typically integrated with magnetic pickup speed sensors, proportional actuators, current transformers, and generator control equipment. It supports isochronous and droop speed control modes for different generator operating conditions.
