Technical Specifications 24VDC power supply, dual-channel AC voltage PT input. Operating temperature: -40℃ ~ +70℃, adjustable synchronization window parameters.
Functional Features Voltage amplitude comparison, frequency difference detection, phase angle monitoring, synchronizing permission output, out-of-step alarm.
Application Scenarios Grid-connected generator synchronization control, multi-generator bus paralleling systems.
Performance Parameters High-precision phase angle sampling, fast difference calculation, reliable blocking for out-of-sync conditions.
Structural Characteristics Rack pluggable logic module, synchronization status and fault LED indicators.
Working Principle The module collects generator voltage and bus voltage signals simultaneously. It continuously calculates voltage, frequency and phase deviation. If deviations are within preset allowable windows, the module sends out closing enable signal for circuit breaker.
Installation Requirements PT signals from generator and bus must come from independent voltage transformers, wiring polarity must be correct.
Usage Notes Verify phase sequence and polarity during commissioning, never short-circuit PT secondary terminals.
