Navajo project report on subsynchronous resonance analysis and solutions

The history of subsynchronous resonance analysis by the Navajo Project leading to the selection of equipment to be applied at Navajo is presented. The analytical techniques used, potential problems discovered, solutions considered and solutions being applied are reviewed. This represents the first complete study of subsynchronous resonance problems on a particular system leading to selection of specific equipment to be applied as a solution to the problem. This information should be of great interest to those studying the subsynchronous resonance problem on other systems.
