GE Energy (Atlanta, Georgia, U.S.) will provide two 500-kV series compensation systems to the China Southern Power Grid Co. to increase the power transfer capability in the Louping-Baise-Mawo transmission corridor.

GE Energy's series compensation systems include capacitors, metal oxide varistors, triggered air gaps, and a fully redundant digital protection and control system based on a GE FANUC programmable logic controller. The series capacitors compensate the transmission line impedance, thereby providing a cost-effective means of increasing the capacity of the transmission lines to deliver power. These systems will be GE's first in China.

China's Southern Power Grid covers four provinces and one autonomous region in South China, including Guangdong, Guangxi, Hainan, Yunnan and Guizhou. The total gross domestic product of the five areas is expected to exceed 6 trillion yuan (US$722.9 billion) by 2020, and their growing economies will consume a large amount of electricity.
