Description
Woodward SPM/D11
Technical Specifications
- Model: SPM-D11
- Type: Microprocessor-based Synchronizing Unit
- Functions: Synchronization, Synch-check, Dead Bus Start
- Compatibility: Designed for use with Woodward and compatible speed controllers/AVRs
Functional Features
- Core Synchronization: Automatic frequency, phase, and voltage matching.
- Safety Interlocks: Synch-check prevents out-of-phase closing.
- Dead Bus Operation: Automatic closing on de-energized buses.
Application Scenarios
Found in existing power plants, marine generators, and industrial facilities that were commissioned with legacy Woodward synchronization systems.
Performance Parameters
- Voltage Inputs: Supports standard generator and bus VT secondaries.
- Control Outputs: Discrete raise/lower for speed and voltage.
- Display: Basic LCD or LED indication for status and parameters.
Material Composition
Robust industrial enclosure with high-quality internal electronics designed for decades of service life.
Structural Characteristics
- Form Factor: Standard panel-mount module.
- Interface: Front-panel buttons and display for local operation.
Working Principle
Monitors generator and bus voltages, calculates slip and phase difference, and outputs discrete raise/lower pulses to adjust the generator until synchronization conditions are met.
Installation Requirements
Follow original installation manuals for wiring and mounting. Ensure proper VT polarity and phase sequence.
Precautions for Use
As a legacy product, ensure spare parts availability. Consider upgrading to SPM-D2 series for enhanced features and USB configuration support.
