Which substations have uninterruptible power supplies

With UPS installations in plants and substations, you can guard against downtime throughout your entire infrastructure. Avoid the irony of a power plant without power with uninterruptible power supplies to ensure the continuity of the utility's supply and minimize disruptions.

In order to eliminate or reduce the loss of important data or control, it may be necessary to provide a level of power protection for your particular needs. An Uninterruptible Power Supply (UPS) can be that answer. These devices are designed to provide continuous power to a load, even with an interruption or loss of utility supply power.

In this case the DC supply is duplicated to each control and relay panel by sectionalizing the DC distribution board and having separate feeders to each panel. Each relay and/or control panel DC circuit associated with each power substation circuit is also monitored for loss of DC supply.

4 Substation Auxiliary Power Supplies 4.1 INTRODUCTION All but the smallest substations include auxiliary power supplies. AC power is required for substation building small power, lighting, heating and ventilation, some communications equipment, switchgear operating mechanisms, anticondensation heaters and motors.

Energy supply companies use DC UPS systems in combination with remote control technology to protect the control systems of their power plants and to ensure the integration of renewable energies through transfer stations and distribution networks such as local secondary substations.

The choice for substation auxiliary supplies lies between lead acid and nickel cadmium cells and variants within these categories. Substation auxiliary AC supplies may be derived from dedicated sources or from additional circuits on low voltage distribution switchgear forming part of the substation's outgoing distribution system.
