Uninterruptible power supplies or UPSs are battery chargers consisting of a combination of convertors, switches and energy storage devices (such as batteries), constituting a power system for maintaining continuity of load power in case of input power failure. 10 CFR 430 Appendix Y 2.27.
It is recommended that each distribution substation should have its own DG Backup so that in case of mains power failure local DG sets are available as backup as per the normal practice. It is not recommended to have a centralized DG Backup to supply 11 KV DG Power to the distribution substations.
During winds, cyclones and storms, the entire distribution system including poles, and conductors collapse taking long time to restore the power supply. The indoor substations work at much lower ambient, say at 28 Degree C, when the outside temperature may be above 40 degree C.
It is not recommended to have a centralized DG Backup to supply 11 KV DG Power to the distribution substations. This will not allow for segregation of essential and non-essential supply. Also in case of any fault in 11 KV feeder cable the whole campus will have no DG Backup.
