China builds world's biggest power grid: report ( 2003-09-22 20:14) (Xinhua)
China has set up the biggest power grid in the world with a combined
installed power capacity of 140 million kilowatts, and a span of 4,600
kilometers across 14 provinces and municipalities, Beijing Daily reported
Monday.
China's two important power grids, the North China Power Grid and Central
China Power Grid, were successfully connected on Friday for the first time, and
the interconnected grid operated smoothly, according to the report.
The interconnected power grid outstrips the Far East Power Grid in Russia in
capacity, the newspaper said, citing sources from state-owned North China Power
Group which runs the North China Power Grid.
The sources said the connection of the two grids will help the power sector
to optimize its electrical power resources, enable the two grids to support each
other in distribution of electricity, and improve operation safety of the power
grids.
The two grids are capable of transmitting 200,000 to 600,000 kilowatts of
electricity to each other.
The connection was made possible thanks to a 210-km, 500-kv transmission
line, which links the Xin'an Transformer Substation of the North China Grid in
Handan City, Hebei Province in north China, with the Huojia Transformer
Substation of the Central China Power Grid in Xinxiang City of Henan Province,
central China, according to the newspaper.
