Description
Woodward 5448-890
Technical Specifications:
- Brand: Woodward
- Model: 5448-890 SPM-D10
- Product Type: Synchronizing Protection Module
- System Integration: Compatible with Woodward 505 and MicroNet control systems
Functional Features:
- Precision Matching: Continuously monitors and compares generator and bus voltages, frequencies, and phase angles.
- Automatic Synchronization: Calculates the optimal breaker close time based on slip frequency to achieve zero-phase-angle closure.
- Safety Interlocks: Prevents breaker closure if synchronization parameters fall outside safe operational limits.
Application Scenarios:
Essential for power generation facilities, microgrids, and industrial plants where multiple turbine generators must be safely paralleled to share electrical loads.
Performance Parameters:
- Synchronization Accuracy: High-precision phase matching
- Response Time: Millisecond-level breaker command output
Material Composition:
Industrial-grade electronic components housed in a protective enclosure designed for control panel integration.
Structural Features:
Modular design compatible with Woodward control racks. Features status indicator LEDs and test points for easy commissioning and troubleshooting.
Working Principle:
The module samples voltage waveforms from both the generator and the bus. It processes these signals to determine the slip frequency and phase difference, issuing a close command at the exact moment when the phase angles align.
Installation Requirements:
Must be installed in a clean, dry control environment. Voltage sensing inputs require properly fused and isolated connections to the generator and bus potential transformers.
Usage Precautions:
Never bypass synchronization safety interlocks. Regularly verify the calibration of voltage and frequency sensing circuits. Ensure the module is correctly configured for the specific generator and grid characteristics.
