Functional Features:

Precise Synchronization Control: Automatically adjusts generator speed and voltage to match grid/load parameters (frequency, voltage, phase angle), enabling smooth grid connection or load coupling without inrush current.
Dual-Mode Operation: Supports both “manual synchronization” (for operator intervention) and “automatic synchronization” (for unmanned, real-time adjustment), adapting to different operational scenarios.
Comprehensive Protection Functions: Integrates over-speed protection, under-voltage protection, over-voltage protection, and phase mismatch protection; triggers alarm or shutdown signals immediately when abnormal conditions occur to prevent equipment damage.
Real-Time Monitoring and Display: Equipped with a built-in LCD screen (128×64 pixels) to display key parameters (generator speed, voltage, frequency, synchronization status) and fault codes; supports parameter setting via front-panel buttons.
Grid Adaptability: Compatible with both 50 Hz and 60 Hz power grids, and supports voltage adjustment for different rated voltage levels of generators, ensuring wide applicability across regions and equipment types.

Application Scenarios:

Power Generation Plants: Used in thermal power plants, hydropower plants, and diesel generator sets to synchronize generators with the public grid before connection, ensuring stable power injection and avoiding grid disturbances.
Industrial Power Systems: Applied in large manufacturing facilities (e.g., steel mills, chemical plants) with on-site backup generators, enabling fast synchronization of backup power to the internal power grid during mains failure.
Marine and Offshore Systems: Integrated into marine generators (for ships, offshore platforms) to synchronize multiple generators in parallel, maintaining stable power supply for navigation equipment, living quarters, and production systems.
Renewable Energy Systems: Used in wind farms or solar hybrid systems with energy storage generators, synchronizing the generator output with the grid to ensure compliant and efficient power feeding.
Large Motor Drives: Applied in industrial scenarios with high-power motors (e.g., water pumps, fans, compressors) to synchronize motor speed with load requirements, optimizing energy consumption and extending motor lifespan.
