Hydroelectric
Leveraging over 80% market share in the synchronizer sector and industry-leading technology in fast transfer switching, our company offers an integrated solution featuring Precision Synchronization + Seamless Transfer + Intelligent Inrush Suppression.
This solution is designed to cover critical scenarios such as generator synchronization, auxiliary power switching, and auxiliary equipment drive, enabling zero-interruption power supply, low-impact switching, and extended equipment lifespan. It is fully adaptable to the complex operating conditions and environmental challenges commonly found in hydropower plants.
Achieves phase angle difference ≤ 0.5°, supporting fast synchronization of multiple generator units. First-time closing success rate exceeds 99.9%, meeting the complex grid-connection demands of hydropower stations with frequent unit starts and stops.
In line with national industrial localization policies, our company has independently developed a fully reliable synchronizer to meet domestic equipment requirements.
Coordinated operation between the fast transfer device and high-speed vacuum circuit breaker achieves total switching time ≤ 20 ms (detection ≤ 5 ms + action ≤ 15 ms), significantly faster than the traditional 500 ms ATS switching. This eliminates voltage sag-induced auxiliary equipment shutdown risks.
Ensures uninterrupted power supply to key loads such as turbine governor systems and excitation systems during source switching, guaranteeing system stability.
Utilizing a microprocessor-based inrush current suppressor (with over 70% market share), the solution addresses transformer and reactor inrush as well as switching overvoltages. Through the “residual flux and bias flux counteraction” principle, the system effectively reduces inrush impact and protects the insulation integrity of primary equipment.
Optimizes circuit breaker closing timing, reducing the risk of arc re-ignition, protecting sensitive hydropower station equipment, and extending equipment lifespan.
In a large-scale hydropower plant deployment, our solution has demonstrated the following results:
Enhanced Power System Stability
Continuous power supply to critical loads reached 100%, effectively eliminating equipment downtime caused by power source transfers.
Extended Equipment Lifespan
By integrating inrush current suppression and overvoltage protection, equipment failure rates were reduced by 30%, significantly extending the service life of key assets.
Improved O&M Efficiency
The intelligent monitoring and diagnostic capabilities reduced the need for manual inspections, leading to a notable improvement in operation and maintenance efficiency.
