Midwest ISO Announces Grid Monitoring System

LCG, Jan. 15, 2004--A new computer system that uses data from tens of thousands of points on the transmission system across the Midwest and beyond has been installed by the Midwest Independent Transmission System Operator, Inc. (MISO), the grid manager said today.

The computer system not only takes data every thirty seconds from 30,000 busses, but also from 87,000 Inter Control Center Protocol (ICCP) locations. Calculations based on the readings provide contingency analyses, which are necessary should a failure take place on a vulnerable part of the grid.

Manitoba, Canada, Pennsylvania and Tennessee are among those areas that feed data into the State Estimator model. James P. Torgerson, president and CEO of the MISO, said in a statement, "Implementation of the State Estimator model is a key operational milestone that reaffirms our commitment to ensuring the safe and reliable transmission of electricity."
