American Superconductor Corporation announced that it received an order for a D-VAR reactive compensation solution from Xiamen Red Phase Instruments Inc. The new D-VAR system is now being used to resolve power quality issues for China Southern Power Grid. Red Phase will install the D-VAR STATCOM system in a 110 kilovolt (kV) substation in the Yunnan province of China. The D-VAR system is being used to connect a 35kV bus line to the substation while regulating voltage, mitigating transient voltage deviations, ensuring high power quality and improving grid stability.

D-VAR dynamic reactive compensation systems are classified as Static Compensators, or "STATCOMs," a member of the FACTS (Flexible AC-Transmission System) family of power electronic solutions for alternating current (AC) power grids.
