The total collapse time to 1 second can cause power grid
The world more seconds can cause power grid KMxtdxdl P [total collapse,
According to the west of yunnan Thai wire and cable co. , LTD. , has learned 】
More years world 'seconds', Beijing time: : special phenomenon.
Fast one second slow for a second time everyone feel not to come out, but experts say the grid fault maintenance, power grid and grid interconnection between time is very precise, if the error of the second, could lead to the whole power grid, power outage or even collapse.
Because based on the earth's rotation of 'world' and the 'atom' is determined based on the atomic oscillation period of the two time scales measuring method is different, and the trend of the earth's rotation has a long slow.
As time goes on, there will be differences between the two time system.
Years, international conference on measurement, when the 'world' and 'atom' between vary over time.
Second, on the coordinated universal time (plus or minus the second
Is a leap second or negative leap seconds)
To try to close to the world, we call it a leap second.
If you encounter a leap second, our mobile phone time from communication stations, automatically adjust.
General watch hand against television, radio, radio table can be adjusted automatically.
Most computer need to manually adjustable, if the computer installed the software, when a school can be automatic alignment.
Although a leap second basic will not affect the daily life of ordinary citizens, fast one second slow for a second time everyone feel not to come out.
But for the aerospace and military, diving, some special industries, such as electric power department, the error of one second is enough to cause a series of influence.
Will fly in space, the spacecraft second nearly kilometers, if sent this second, error is big, may offset the spacecraft orbit, the spacecraft landing sites may be miles behind, what's worse is the safety of the ship will be a great threat.
On the network communication, coordinated universal time is used in a lot of Internet standards, as the network time protocol is one of them.
If there is a second error, so many computers around the world all of a sudden all messed up.
In some systems, the computer clock displays need to scroll to the next minute seconds, or display the first seconds twice.
Results calculated there was a leap second chance to back in time, lead to system error or central processing unit (
In terms of power grid, power grid fault maintenance, power grid and grid interconnection between time is very precise, if the error of the second, could lead to the whole power grid, power outage or even collapse.
