Abstract :
The transient energy function (TEF) method is a direct method of power system transient stability analysis. While research work on the subject continues, questions have been raised regarding potential applications of the method for online dynamic security analysis (DSA). Some of the problems are investigated, and solutions for problems arising in the use of TEF in DSA, based on tests using real utility data, are suggested. A prerelease version of a TEF program called DIRECT (version 2.9) was used in the tests. The results indicate that TEF does have a place in DSA in conjunction with other available DSA methods
