Sensors might help protect power grids
AMES, Iowa, June 27 (UPI) -- U.S. scientists are creating a network of sensors to
monitor electricity transmission systems to prevent power disruptions from
cascading into blackouts.
With the wireless sensors detecting suspicious activity at utility poles, the Iowa
State University researchers say the system would be especially useful at quickly
locating breakdowns. That could allow power companies to react in time to avoid
widespread blackouts.
The research team, led by electrical and computer engineering professors
Arun Somani and Jerry Junkins, says the network of sensors might also aid
power companies in quickly locating problems when severe weather brings down
electrical lines.
The project is supported by a $400,000 grant from the National Science
Foundation and $150,000 from Iowa State's Information Infrastructure Institute.
