Abstract

In this paper, a new application of time frequency distribution algorithm (TFD) is introduced for analyzing subsynchronous resonance (SSR). A computation algorithm is derived to utilize the information obtained from TFD for detecting of subsynchronous modes. Three different study systems with different network configuration and different series compensation arrangements are used to measure the effectiveness of TFD and the computation algorithm in detecting network eigenvalues. Comparison between the results obtained from TFD computation algorithm and from the mathematical model is presented for each study system
