Description
The 9907-028 is a Woodward SPM-A synchronizer used to help match generator speed and phase prior to paralleling with other devices. this synchronizer has its automatic circuit breaker closure and synchronization of generators, selectable match-up time and output impedance, and adjustable dynamics.
Applications
Thermal Power Plants: Matches steam turbine generators to high-voltage grids.
Shipbuilding Plants: Synchronizes diesel generators with marine switchboards.
Petrochemical Plants: Manages emergency backup power during grid failures.
Emergency Power Plants: Enables fast multi-generator grid interlocking.
Industrial Power Plants: Connects cogeneration units to main electrical systems.
Features
Automatic synchronization: Automatically synchronizes generators for seamless integration.
Adjustable Dynamics: Allows fine-tuning of synchronization parameters for optimal performance.
Frequency and Phase Matching: Matches both frequency and phase, with optional voltage matching.
Selectable Match-Up Time: Provides flexibility in synchronization timing.
Automatic circuit Breaker closure: Ensures safe and reliable operation during synchronization.
Additional Features
The 9907-028 is compatible with Woodward 2301, 2301A, EPG, and 2500 series. A user switch provides four modes: OFF, RUN, CHECK, and PERMISSIVE.
RUN mode enables normal synchronization and breaker closure signals, with lockout activation after signal verification. CHECK mode allows synchronization without breaker closure permission. PERMISSIVE mode prevents synchronization from affecting engine speed.
