Synchronizing Multiple Generating Units

In hydropower plants and other multi-generator sites, several units often need to connect to the grid simultaneously. Traditionally, two approaches were used:

One synchronizing device per unit → reliable but costly.
Shared synchronizing device across units → cost-saving but requiring numerous external selector switches, leading to complex wiring and higher failure risk.

Operators asked: Can one device support multiple units, while integrating synchronizing-point selection internally?

The ODES Answer: Multi-Unit Manual Synchronizing Device

Building on the proven manual synchronizing device platform, ODES developed the multi-unit manual synchronizing device with integrated synchronizing-point selection.

ODES MBCR652C Manual Synchronizing Device

Key Features

Integrated synchronizing-point selector: Eliminates external switching hardware.
Reduced wiring: Significantly fewer external connections, simplifying construction and fault tracing.
Higher reliability: Unified logic and reduced hardware improve system consistency and operational dependability.
Lower cost: One device supports multiple units, cutting procurement and installation expenses.

Technical and Engineering Value

Simplified commissioning: Less wiring and fewer manual switches shorten FAT/SAT procedures.
Consistency across units: Centralized logic ensures uniform performance across multiple generating units.
Enhanced maintainability: Clearer system architecture reduces troubleshooting complexity.
Protection-class design: Developed to IEC 60255 standards, ensuring accuracy, EMC immunity, and environmental resilience.

Conclusion

The path from five separate meters → one integrated device → multi-unit synchronizing reflects not only technological progress but also customer-driven evolution. Today, the ODES multi-unit manual synchronizing device delivers safer, simpler, and more cost-efficient synchronizing for hydropower and multi-generator projects.
