Description
Woodward SPM-D105448-906
Technical Specifications
- Part Number: 5448-906.
- System Type: SPM-D10 Series Synchronizer.
- Processing: Microprocessor-based control logic.
- Compatibility: Designed for use with compatible speed governors and voltage regulators.
Functional Features
- Automatic Synchronization: Automatically matches frequency, phase, and voltage before closing the generator breaker.
- Synch-Check: Verifies grid conditions before allowing breaker closure.
- Dead Bus Start: Capable of closing the generator breaker without synchronization when the bus is de-energized.
- Analog/Discrete Outputs: Provides bias signals to adjust prime mover speed and generator excitation.
Application Scenarios
Widely applied in power plants, industrial facilities, and marine applications requiring reliable generator paralleling and grid synchronization.
Performance Parameters
- Sync Accuracy: High-precision phase and voltage matching to prevent mechanical stress.
- Response Time: Fast processing for rapid synchronization during emergencies.
Material Composition
Industrial-grade printed circuit boards housed in a robust, protective enclosure designed for control panel integration.
Structural Characteristics
- Form Factor: Compact module designed for DIN rail or panel mounting.
- Indicators: Front panel LEDs for status, synchronization window, and breaker closure.
Working Principle
Continuously monitors generator and busbar voltages, calculating the slip frequency and phase angle difference. When the parameters fall within the predefined synchronization window, it issues a close command to the generator circuit breaker.
Installation Requirements
Connect voltage inputs with correct polarity. Ensure proper shielding of measurement cables to prevent electromagnetic interference.
Precautions for Use
Always verify the synchronization window settings match the generator and breaker specifications. Never bypass the synch-check function during normal operation.
