摘要：

The higher-order spectra for signal processing in electrical power engineering was analyzed. It is found that high-resolution spectrum estimation methods, such as MUSIC, can be effectively used to identify the loss of synchronism of synchronous machines. Under high-SNR conditions, correlation and cumulant based results are similar. Under poor SNR conditions, when the additive Gaussian noise is colored, only cumulant based methods indicate the correct number of signal components.
