The solution provides high-precision automatic synchronization control with a phase angle deviation of ≤0.5°, supporting fast grid connection of multiple generator units with a first closing success rate exceeding 99.9%. It is well suited for hydropower plants with frequent unit start-stop operations and complex synchronization requirements. In response to localization and reliability demands, GoLead Intelligent has independently developed fully domestic synchronization devices, ensuring high reliability while meeting localization compliance requirements.

By coordinating fast transfer devices with high-speed vacuum circuit breakers, the solution achieves an end-to-end switching time of ≤20 ms (≤5 ms detection + ≤15 ms operation), far outperforming conventional automatic transfer schemes with typical response times of around 500 ms. This millisecond-level seamless switching effectively avoids auxiliary equipment outages caused by voltage dips and ensures uninterrupted power supply to critical systems such as turbine governors and excitation systems, maintaining overall system stability.

The solution integrates microprocessor-based inrush current suppressors with a market coverage exceeding 70%, specifically addressing inrush current and operational overvoltage issues during the switching of transformers and reactors. Using the proprietary "residual flux and bias flux cancellation" technology, impact currents are significantly reduced, protecting primary equipment insulation. In addition, phase-selection control optimizes circuit breaker closing timing, minimizing arc re-ignition risks, safeguarding sensitive hydropower equipment, and extending overall equipment service life.
