Implementation of new approach to determination of synchronous-machine parameters from tests

摘要

This is a follow-up to a published paper dealing with a new theory on the analysis of the results of tests on generators in order to determine electromagnetic parameters. The application of the new theory to tests such as sudden stator short-circuit tests, stator-decrement tests, rotor-decrement tests and frequency-response tests is discussed, and examples of the analysis of such tests are presented. Further analysis, using the new theory, of the published results of tests carried out by the CEGB at Goldington and Northfleet power stations, solves some of the problems which were encountered in the original analyses of these tests. Many comparisons are made between old and new-theory results to demonstrate the worth of the latter.
