Proposed Terms and Definitions for Subsynchronous Oscillations

Abstract

This paper presents proposed terms, definitions and symbols in pursuit of Electric Utility Industry uniformity and common understanding in the analysis of subsynchronous resonance. For the purpose of this paper the discussion is limited to series compensated transmission systems. These definitions are recommended, where applicable, in other unique areas encompassing subsynchronous oscillations. The work presented is a product of the Subsynchronous Resonance Working Group as part of the activity of the IEEE System Dynamic Performance Subcommittee.
