To be able to keep all users’ data safe, all mobile operators need a reliable backup power system for their data centres. ComAp has also delivered a solution for a local data centre. To ensure N+1 redundancy criteria were met, the ‘H-system’ configuration was used in this application. This configuration allows the interconnection of two mains incomers and two 1,800-kW standby generators through a bus-tie breaker into a redundant standby system. Various configurations of the site provide flexible distribution of the power from the mains incomers, or one or both generators to the load feeders. Everything is controlled by ComAp InteliGen NT and InteliMains NT controllers and the whole site is monitored using InteliVision 17Touch screens in the control room.
