Product Introduction

The Woodward 8271-467 Load Sharing and Speed Control Module is a robust and intelligent controller designed to govern engine speed and manage load sharing across multiple generator sets operating in parallel. Purpose-built for applications where precise control, synchronization, and stable power distribution are essential, this module is part of Woodward’s acclaimed 2301D/LS and legacy series.

Equipped with analog and digital interfacing capabilities, the 8271-467 supports real-time communication between generators, allowing for uniform power contribution while maintaining rated frequency and stability. It enables both droop and isochronous load sharing modes, making it suitable for utility-grade applications and isolated power systems.

With proven dependability in power generation, marine propulsion, and oil & gas sectors, this controller is a cornerstone of distributed energy resource (DER) systems and backup power infrastructures requiring unmatched control precision.

Product Applications

The Woodward 8271-467 controller serves as a central element in multi-unit generator and engine systems, where it ensures reliable synchronization and proportional power delivery. Key application areas include:

1. Power Plants (Prime and Standby)
   Controls engine-driven generators in isolated or utility-parallel operation for stable frequency and voltage.

2. Marine Vessel Propulsion Systems
   Maintains steady engine speed and load balancing in propulsion and auxiliary generators aboard ships.

3. Oil & Gas Processing Facilities
   Manages power generation units operating in load sharing across oil fields, refineries, and gas processing stations.

4. CHP (Combined Heat and Power) Systems
   Balances energy output between electrical and thermal demands in cogeneration facilities.

5. Mobile Power Units and Rental Gensets
   Enables rapid deployment and synchronization of multiple gensets for temporary power installations.

6. Industrial Plants with Distributed Loads
   Ensures equitable load management among several generators operating within large industrial facilities.
