Modular Data Centre

A contract to build and operate a new Data Centre based in Almaty, former capital of Kazakhstan, was recently awarded to a leading System Integrator. After lengthy discussions, the Integrator chose AJ Power to provide a back up power supply solution.

The original specification required 5 x 1650kVA Standby generating sets synchronised with each other to provide backup power during the power failure on an N + 1 scheme.

However, after discussions and meetings in Almaty, an alternative solution was agreed. The solution provided by AJ Power consisted of 5 x 1650kVA standby power generating sets powered by Perkins 4012-46TAG2A engines coupled with Newage Stamford alternator with four units working on an island mode and the fifth to act as a ‘swing set’ as a backup in case of a failure of one of the four sets.

To meet the required timelines, it was decided all sets would be containerised locally. AJ Power was heavily involved in the acoustic container design.

Due to the special monitoring requirements involving high security demand, AJ Power needed to provide a solution that could enable the customer to monitor and control all units offline. A custom HMI solution was provided, to monitor and control a standard Genset mounted Insight3250 controller via a hardwired Ethernet connection between the customer’s own PC and the communication card fitted to the controller.

The bespoke graphics simply needed to be installed on the customers PC with no additional or separate touch panel required.

This system will give the operator a clear overview of all five AJ1650 generating sets from one screen with the ability to click into each individual generating sets for a more detailed view.

Within the detailed view the customer will be able to view all of the important operating parameters from the genset as well as remotely start /stop the machine or acknowledge any faults.

The main challenge that AJ Power had on this project was the extremely tight delivery schedule. Once the contract was signed, drawings had to be provided and approved, gensets manufactured and tested whist still achieving despatch of the first units within a six week period.

The second batch was shipped the following week, meeting the customers’ requirements.
