Technical Specifications 24VDC nominal power supply; built-in high-precision AC voltage and current sampling circuits; discrete I/O channels and communication ports; conforms to industrial EMC standards. Operating temperature: -40℃ ~ +85℃.
Functional Features Generator and busbar synchronizing monitoring; automatic synchronizing and breaker close command; active and reactive load balancing; real-time electrical parameter measurement; fault alarm and timestamped event logging.
Application Scenarios Multi-unit diesel and gas generator parallel power stations, grid-connected power generation systems.
Performance Parameters High synchronization precision; fast load adjustment response; stable power balance under dynamic load changes.
Structural Characteristics Panel-mounted metal shielding housing, front LCD display and operation keypad, screw-type wiring terminals.
Working Principle The controller continuously samples voltage, frequency and phase signals of generator and busbar. When synchronization conditions are satisfied, it outputs a closing signal for the circuit breaker. Afterwards, it sends raise/lower commands to governors and AVRs to evenly distribute load across paralleled generators.
Installation Requirements Flush panel installation; separate AC sampling cables and high-power cables; reliable shielding grounding.
Usage Notes Check CT and PT polarity and wiring before commissioning; optimize load sharing parameters during on-site tuning.
