Description

Woodward LS-511

Technical Specifications

  • Function: Automatic synchronization and load sharing.
  • Communication: CANopen interface for integration with EASYGEN controllers.
  • Measurement: True RMS voltage and frequency monitoring.

Functional Features

  • Precision Sync: Matches voltage, frequency, and phase angle before breaker closure.
  • Safety Interlocks: Prevents out-of-phase closing and unsafe paralleling.
  • Bus Tie Control: Manages synchronization between multiple bus sections.

Application Scenarios
Used in multi-generator power plants, microgrids, and facilities with complex utility interconnections.

Performance Parameters

  • Sync Accuracy: High-precision phase and voltage matching.
  • Response: Fast processing for rapid synchronization.

Material Composition
Industrial electronic components with conformal coating for environmental protection.

Structural Characteristics
DIN rail or panel mount module with front-panel status indicators.

Working Principle
Continuously monitors the generator and bus voltages. When the generator is within the predefined sync window (voltage, frequency, and phase), it sends a close command to the generator breaker.

Installation Requirements
Connect voltage and frequency inputs with correct polarity. Ensure CAN bus termination is correct.

Precautions for Use
Never bypass synchronization checks. Verify settings match system requirements before commissioning.
