Description
Woodward 9907-026
Technical Specifications
- Model Series: 9907 Series
- Output Type: Analog Output
- System Compatibility: Designed for integration with Woodward speed control systems and SPM-A synchronizers
Functional Features
- Active Load Sharing: Adjusts the load signal of each generator set so that the load signal voltage is identical across all units at full load.
- Isochronous Load Sharing: Operates in droop mode and interfaces with synchronizers to bias the summing point for seamless grid synchronization.
- Adjustable Calibration: Features an internal potentiometer for precise calibration of load signal matching.
Application Scenarios
Essential for power plants, marine vessels, and industrial facilities operating multiple diesel or gas generators in parallel on an isolated or grid-tied bus.
Performance Parameters
- Signal Accuracy: High-precision analog signal conditioning to ensure proportional load sharing.
- Response Stability: Maintains stable load distribution during transient load changes.
Material Composition
Housed in a robust industrial enclosure with conformal-coated printed circuit boards to protect against moisture, dust, and electromagnetic interference.
Structural Characteristics
- Adjustment Interface: Internal potentiometer accessible for fine-tuning load signal voltages.
- Terminal Block: Clearly labeled terminals for analog inputs, outputs, and power supply.
Working Principle
The module continuously monitors the generator’s load and adjusts its analog output signal. When paralleled, it communicates with other modules to ensure each generator carries its proportional share of the total bus load based on its rating.
Installation Requirements
Install in a climate-controlled control panel. Keep wiring lengths to a minimum and route through conduit to minimize electrical noise, especially from SCR devices.
Precautions for Use
Use a single-point ground and take control power directly from the battery. Do not use distribution points or starter terminals for control power to prevent noise interference.
