Overview

The Woodward SPM-D2-10 (Model 8440-2166) is a high-performance synchronizer tailored for industrial and utility-scale power systems. It automates the synchronization process between a generator and a live bus or utility grid, ensuring seamless and safe connection. With its advanced microprocessor-based design, the SPM-D2-10 offers fast response times, configurable parameters, and robust protection features.

Moreover, the unit features a two-line LCD display with a built-in synchronoscope and breaker status indicators, enabling clear and intuitive operator interaction. In addition, its compact form factor and flexible power supply options make it suitable for both new installations and retrofit projects.

The SPM-D2-10 supports both manual and automatic breaker closure modes, and its configurable relay outputs allow integration with a wide range of control architectures. Therefore, it’s widely used in critical infrastructure where synchronization accuracy and system reliability are paramount.

Technical Data

Typical Applications

• Power Plants: Synchronizing backup or peaking generators with utility grids.

• Marine and Offshore: Ensures safe paralleling of onboard generators with shore power or other units.

• Industrial Facilities: Used in manufacturing plants for generator-to-bus synchronization.

• Data Centers and Hospitals: Enables seamless generator engagement during utility outages.

• Microgrids and Distributed Energy Systems: Facilitates grid-tied and islanded operation transitions.

For instance, operators in remote or unmanned facilities benefit from its automatic breaker control and real-time feedback. In addition, its wide voltage and frequency range supports global deployment across 50 Hz and 60 Hz systems.
