Technical Specifications 24VDC power supply, dual-channel PT AC voltage input. Operating temperature: -40℃ ~ +70℃, adjustable synchronizing window parameters.
Functional Features AC voltage sampling, frequency and phase angle measurement, synchronization condition judgment, out-of-step alarm, closing permission output.
Application Scenarios Grid-connected generator synchronization control, generator bus voltage monitoring and protection.
Performance Parameters High-precision phase detection, fast deviation calculation, reliable blocking under asynchronous status.
Structural Characteristics Rack pluggable logic module, synchronization status and fault LED indicators.
Working Principle The module continuously samples voltage waveforms from generator and bus PT loops. It compares amplitude, frequency and phase. When all deviations are within preset allowable ranges, it releases the synchronization closing permission.
Installation Requirements Ensure correct PT wiring polarity and phase sequence, never short-circuit PT secondary terminals.
Usage Notes Perform synchronization function test before grid-connected commissioning, adjust synchronization window according to site requirements.
