Capita Secure Data Centre — Protection Study
A detailed loadflow, short circuit and protection study for a secure data centre
The challenge
Aurora was approached by Capita to carry out power system analysis and an overall protection study for a secure classified data centre in Cornwall. The site was undergoing a significant expansion and needed a full independent review and protection coordination study on a critical and challenging network.
What Aurora did
We carried out a full loadflow and short circuit study to validate the system design and confirm that all equipment was correctly rated for the required duty. This included both main and failover supplies, as well as sustained operation from backup diesel generator sets. We then undertook a detailed protection coordination study for the entire network, covering the HV, LV and UPS systems and the cable differential protection network. The coordination was unusually complicated because of the multiple operating configurations, closed-ring HV and LV systems, directional protection and alternative setting groups.
