China has developed smart power grid technology that cuts blackout recovery time to a 10th of a second, according to state media, which said the innovation was expected to play a bigger role in ensuring the safe and stable distribution of electricity worldwide.
The grid protection technology enables power grid faults to be isolated and restored within a hundred-millisecond window, compared with the hours otherwise required, according to a Science and Technology Daily report on Tuesday.
It also solves the problem of identifying micro-current faults at the hundred-milliampere level.
The development, which is in use in industries such as power, steel and rail transport, has been deployed across the country and exported to 12 nations. It was developed by the China Electric Power Research Institute, an affiliate of the State Grid Corporation of China.
“As a key technological support for the safe operation of modern power systems, this achievement not only ensures the reliability of power supply in the capital and the country, but also promotes the intelligent manufacturing upgrade of power equipment,” the report said.
