000000311 520__ $$aThe out-of-step operation conditions of a synchronous machine may occur as a result of a power system three-phase fault. The mostly used methods of identification of loss of synchronism are not secure enough. In the paper a new method using high-resolution spectrum estimation method is presented. In the case of asynchronous operation of a synchronous machine the current waveform in the stator winding can be resolved into three components, which frequencies differ insignificantly. High-resolution subspace methods enable to estimate the frequencies and on this way to identify the asynchronous operation.  Copyright © 2003 IFAC
