1. Installation context
Ensuring a continuous power supply is a significant challenge for any Datacenter. Even a brief outage of a few seconds can have serious consequences on hosted services. This project took place in the Philippines, in a strategic data center.
The objective was twofold: to parallel five existing gensets and to replace an open-transition ATS with a soft-transition ATS (Soft close). This evolution ensures a more reliable and smoother backup power supply, while avoiding the disruptions caused by sources switching.
The installation is based on a robust and diversified energy infrastructure, including :
- 2 Mitsubishi gensets, 1500 kVA – 400 V
- 2 Mitsubishi gensets, 1000 kVA – 400 V
- 1 Cummins genset, 750 kVA – 400 V
- 2 power transformers, 1500 kVA – 34.5 kV/400 V
- 2 power transformers, 1000 kVA – 34.5 kV/400 V
- 1 power transformer, 750 kVA – 34.5 kV/400 V
Thus, paralleling these sources and modernizing the ATS system now ensures a secure energy supply. They also guarantee seamless transitions, which is essential for a datacenter.
2. Issues encountered by the customer
Before modernization, the installation had a significant limitation: the lack of redundancy in the backup power supply. In practical terms, availability relied on the proper functioning of a single genset. For a critical site, this risk was unacceptable.
However, power continuity is an absolute requirement for IT infrastructures. Even a temporary shutdown can affect sensitive equipment and disrupt services.
The implementation of redundancy through genset paralleling was therefore the most suitable solution.
The solution we provided
To secure the site's power supply and ensure continuity of service, three types of CRE Technology controllers were integrated:
- 5 GENSYS COMPACT PRIME for genset management and paralleling
- 5 MASTER COMPACT for load transfer control in no break change over mode
- 5 BTB COMPACT for busbar management and protection
This architecture ensures perfect source synchronization, complete redundancy and seamless power transitions.
1. GENSYS COMPACT PRIME module – Genset management
Five GENSYS COMPACT PRIME modules have been installed (one for each genset), to enable autonomous and coordinated management:
- Engine start/stop: automated activation and shutdown of the gensets based on grid status
- Synchronization capability: automatic synchronization of the 5 groups with each other and with the main power grid, ensuring seamless transition back to the grid
- Active and reactive load sharing: optimized distribution of active and reactive power between the gensets
- Generator power management (kW, kVAR): efficient control of delivered power for optimal operation
2. MASTER COMPACT module – Load transfer management
Five MASTER COMPACT modules have been integrated to modernize the ATS system and ensure reliable switching:
- Grid fault detection: automatic identification of faults or outages on the main source
- Automatic transfer to backup source: immediate switchover to gensets in the event of an outage
- Seamless load transfer (No Break Change Over): soft transition (Soft Close) with no interruption for critical equipment
3. BTB COMPACT module – BTB circuit-breaker management
The five modules BTB COMPACT modules installed ensure safe management of interconnections between busbars:
- Paralleling breaker control: supervision of the opening and closing of breakers
- Synchronization with grid or gensets: paralleling with the grid source or gensets
- Active and reactive load sharing: balanced distribution of active power and reactive power for reliable power supply
The integration of BTB COMPACT significantly simplified the installation design by enabling a clear and structured segmentation of the power plant. Their implementation is particularly intuitive: it only requires identifying the segments located on either side of the tie breaker, which helps optimize configuration and commissioning time.
Conclusion
Thanks to this modernization, operation of the power plant is now simple, flexible and totally secure. It fully meets datacenter redundancy requirements. The power plant can be to run in normal mode or in parallel with the generators, with seamless transitions made possible by the coordination of CRE Technology controllers.
This project perfectly illustrates the added value of CRE Technology solutions in critical environments:
- GENSYS COMPACT PRIME ensures reliable synchronization and optimal load sharing
- MASTER COMPACT ensures a smooth transition between sources
- BTB COMPACT enhances plant safety and flexibility
In conclusion, this modernization provides the client with a reliable, scalable power plant ideally suited to the demands of a modern datacenter. It once again demonstrates CRE Technology's ability to support its partners in their most demanding projects.
