Woodward 8273-128 2301D-ST Digital Load Sharing and Speed Control Module

Product Description

High-Precision Digital Governing for Steam Turbines

The Woodward 8273-128 is a specialized control module from the 2301D-ST series, engineered for digital load sharing and speed control of single-valve steam turbines and engine-driven generator sets. This microprocessor-based unit provides the critical logic required for parallel generator operation, ensuring that multiple units distribute the electrical load proportionally and efficiently. The 2301D-ST (Steam Turbine) variant is specifically tuned for the unique response characteristics of steam-driven prime movers, delivering deterministic speed regulation and seamless synchronization to the bus.

Advanced Load Sharing and Synchronization

The 8273-128 acts as the primary governor, utilizing digital electronic sensing to maintain precise frequency control under varying load conditions. It features an integrated load sensor that monitors the generator's power output, allowing the module to communicate with other 2301D units for automatic load balancing. This digital architecture eliminates the drift associated with legacy analog controls and provides a more robust interface for modern SCADA and DCS systems. The unit is designed for "normal" mounting locations (non-hazardous), providing a cost-effective yet high-performance solution for industrial power houses.
