Ojo Wins Sigma Xi Research Award

Thanks to his work on alternative energy sources for electric power generators, Joseph O. Ojo earned one of Tennessee Technological University's highest honors for research.

Ojo, associate professor of Electrical Engineering, received the 1996 Sigma Xi Faculty Research Award. The award was based on Ojo's article "Dynamics and System Bifurcation in Autonomous Induction Generators," published in the July/August 1995 issue of IEEE Transactions in Industry Applications.

Faced with dwindling global energy resources, engineers are increasingly studying non-conventional energy sources, such as wind and water, for electrical power generation. An intensely investigated alternative source, the induction generator system, holds promise, but questions remain about certain aspects of the system's operation.

Ojo's research significantly improves understanding of induction generation. In his article, he provides a mathematical model of stand-alone generators as well as a computer simulation strategy for the system and verification of simulation experiments.

"The uniqueness of the paper stems from the intermingling of an otherwise abstract mathematical theory, experimental results and computer simulations to provide solutions to the long-standing and heretofore unresolved practical problems in autonomous electric power generation," says Marie Ventrice, associate dean of the College of Engineering at Tennessee Tech.

The research award, given annually by our chapter of Sigma Xi, recognizes an outstanding research contribution published in a professional journal. Ojo's article also received an award from the Electric Machine Committee of the Institute of Electrical and Electronic Engineers Industry Application Society.
