دانلود Effective method of subsynchronous resonance detection and its limitations

Abstract

The paper presents a novel approach for detection of subsynchronous resonance phenomenon SSR in a series compensated transmission system. The presented method is designed to detect subsynchronous resonance frequency and amplitude in very short time to prevent the failure of transmission systems, which can likely happen if the subsynchronous resonance amplitude is not be mitigated quickly enough. The specific signal demodulation of AC current measurement was introduced in order to detect the subsynchronous resonance. The algorithm was investigated with the use of different test cases based on IEEE second benchmark model of subsynchronous resonance. The results of calculations indicate that the presented concept is an adequate proposition for detection of subsynchronous frequencies.
