Product Description: Woodward 5461-654 Automatic Synchronization Controller / Digital Speed Regulator

Product Model: 5461-654

Brand: Woodward

Product Type: Microprocessor Synchronizer / Automatic Synchronization and Load Controller (Microprocessor Synchronizer & Load Controller)

I. Product Overview

The Woodward 5461-654 is a dedicated automatic synchronization and load control module specifically designed for three-phase AC generators (steam turbine generators, gas generators). Its core function is to achieve automatic and high-precision synchronization and grid connection of the generator with the power grid, and to complete precise load distribution and regulation after grid connection. It is the key intelligent unit in the "grid connection - load carrying" section of the 5461 series, widely used in scenarios requiring parallel operation such as power generation, petrochemical industry, and ship propulsion.
