Description
Woodward 9907-028
Technical Specifications:
- Brand: Woodward
- Model: 9907-028
- Product Type: Digital Synchronizer Module
- Power Supply: 18-32 VDC
Functional Features:
- Precision Synchronization: Continuously monitors incoming generator and bus parameters to calculate the exact breaker closing time.
- Load Management: Supports active power sharing and power factor control for stable parallel operation.
- Local Diagnostics: Features an integrated display and keypad for real-time parameter monitoring and configuration.
Application Scenarios:
Widely deployed in power generation plants, marine propulsion systems, and industrial cogeneration facilities requiring seamless generator paralleling.
Performance Parameters:
- Synchronization Accuracy: High-precision voltage and frequency matching.
- Operating Temperature: Designed to withstand harsh industrial environments.
Material Composition:
Housed in a ruggedized industrial enclosure with conformal-coated internal electronics to resist moisture, vibration, and electromagnetic interference.
Structural Features:
Compact modular form factor featuring a front-panel LCD interface, tactile navigation keys, and secure backplane connectors.
Working Principle:
Samples the voltage, frequency, and phase angle of both the generator and the bus. It calculates the slip frequency and determines the precise closing instant to achieve zero-crossing synchronization.
Installation Requirements:
Mount securely in a standard control cabinet. Use shielded cables for all voltage and frequency sensor inputs to prevent signal noise.
Usage Precautions:
Ensure all synchronization parameters are correctly configured for the specific generator set. Regularly verify sensor inputs to prevent false synchronization.
