TVA to share technology

NORTH MISSISSIPPI — The Tennessee Valley Authority (TVA) is sharing its success with a computer system developed to collect information on the eastern U.S. power grid, and support the creation of a smart grid, by making the system openly available to others in the industry.

The technology developed by TVA is called SuperPDC. PDC stands for phasor data concentrator, a system used to determine the health of a power grid. The system collects data from devices called phasors, which measure electric current 30 times every second. Each measurement carries a precise time stamp taken from global positioning system satellites, so that the entire electric grid can be analyzed at any moment in time.

By making the system available in the industry, others can use and contribute to the computer system as TVA tests and releases new versions. The entire TVA phasor platform also has been released under a public license agreement that allows the creation of new commercial applications based on it.

TVA announced its open PDC approach at a meeting of utility representatives, computer system vendors and researchers interested in improving the use of data on the power grid. The meeting in Chattanooga, Tenn., was led by the North American Electric Reliability Corporation.

“We’re hopeful that TVA’s technology will enable both computer system vendors and the electric power industry as billions of dollars are invested to modernize the power grid over the next several years,” said TVA vice president of power control systems Jacinda Woodward. “The open source process will allow the TVA SuperPDC to undergo broad review to improve its performance, usability and security.”

The operational success of the TVA technology led the North American Electric Reliability Corporation to contract with TVA to expand the system into a regional PDC, which is targeted for wide industry use beginning in 2010. TVA currently collects information from the power grid throughout the eastern half of North America.
