Woodward | 9907-028+5464-414 | Synchronizer Control Module
Description
- Manufacturer: Woodward
- Model: 9907-028
- Ordering Information: 9907-028
- Catalog: SPM-A Speed and Phase Matching Synchronizer
- Origin: United States (US)
- HS Code: 85389091
- Dimensions: 16 cm x 16 cm x 12 cm
- Weight: 0.8 kg
Details
The SPM-A Synchronizer is designed to bias the speed of an off-line generator set to match the frequency and phase of another generator or the utility bus. It automatically issues a contact closure signal to close the circuit breaker when frequency and phase are within specified limits. This phase-locked-loop synchronizer ensures precise matching.
Key Features
- Voltage Matching: Generates additional raise/lower signals to the generator's voltage regulator, ensuring voltage matches within the specified tolerance before breaker closure.
- Single and Multiple Unit Synchronization: One synchronizer can control up to seven paralleled generators simultaneously.
- Output Options: High impedance, low impedance, and EPG, selected based on the engine control type.
- Input Voltage: 120 or 208/240 Vac.
- Phase Window: 10-degree phase window.
- Dwell Time: 1/8, 1/4, 1/2, or 1 second (internally switch selectable, factory set for 1/2 second).
Theory of Operation
The SPM-A Synchronizer monitors the phase angle and frequency of both the bus and the off-line generator. Voltage inputs undergo conditioning through filters for accurate measurement. A phase offset potentiometer allows for adjustment of phase errors, ensuring precise synchronization.
Operating Modes
The unit features a user-installed mode switch (four-position: OFF, RUN, CHECK, PERMISSIVE) to control the relay driver, enhancing operational flexibility and safety
