Technical Specifications 24VDC power supply; AC voltage and current sampling circuit; discrete input/output and communication interface; EMC anti-interference design. Operating temperature: -40℃ ~ +85℃.
Functional Features Generator auto-synchronization; circuit breaker closing control; active and reactive load sharing; electrical parameter measurement; fault alarm and event record.
Application Scenarios Multiple diesel/gas generator parallel power plants and grid-connected generation systems.
Performance Parameters High synchronization accuracy, balanced load distribution, fast adjustment response to load variation.
Structural Characteristics Panel mounting metal housing, front LCD and membrane keypad, screw terminal blocks.
Working Principle Continuously sample generator and bus electrical parameters, calculate phase, frequency and voltage difference. When synchronizing conditions are met, output breaker close signal, and adjust governor and AVR to balance load among generators.
Installation Requirements Panel flush installation; separate AC sampling wires and power wires, reliable shielding grounding.
Usage Notes Verify CT and PT polarity before commissioning; tune load sharing parameters on-site.
