Dynamic voltage restoration (DVR)

Dynamic voltage restoration (DVR) is a method of overcoming voltage sags that occur in electrical power distribution.These are a problem because spikes consume power and sags reduce efficiency of some devices. DVR saves energy through voltage injections that can affect the phase and wave-shape of the power being supplied.

Devices used for DVR include static var devices, which are series compensation devices that use voltage source converters (VSC). The first such system in North America was installed in 1996 – a 12.47 kV system located in Anderson, South Carolina.
