High-Precision Synchronization and Grid-Connection Control

As a synchronization unit module, it performs highly accurate measurement of key electrical parameters including voltage, frequency, and phase angle. During generator grid-connection operations, the module determines the optimal closing moment, reducing mechanical and electrical impact on both the generator and the power grid.
In industrial production environments, it enables precise synchronization of multiple devices or motion axes, ensuring coordinated operation across complex production processes.

Comprehensive Protection Functions

The module integrates multiple protection mechanisms—overvoltage, undervoltage, underfrequency, incorrect phase sequence, and excessive phase-angle deviation. These protections prevent equipment damage or grid disturbances during generator synchronization. In industrial automation scenarios, they also help prevent mechanical faults, equipment collisions, and production accidents resulting from asynchronous operation or circuit abnormalities.

High Adaptability and Easy System Integration

A modular design allows flexible configuration of operating parameters through software, supporting diverse application requirements in power plants, production lines, packaging machinery, and more.
Standardized communication interfaces and modular hardware architecture enable seamless integration into existing automation or control systems, significantly reducing modification effort and upgrade costs.

Typical Application Scenarios

Power Generation: Serves as core synchronization equipment in power plants and substations, performing automatic synchronization between generators and the main grid.

Industrial Self-Generation Systems: Used in factories with in-plant power generation to manage parallel operation between local generators and the public grid, ensuring stable and reliable power supply.
