| Abstract: | This paper reviewed mechanism,analysis methods,control measures of low frequency oscillation and its exiting problems in power system. An online monitoring system of low frequency oscillation based on Wide Area Measurement System (WAMS) was presented. The trends were indicated to combine the spectral algorithm with Prony algorithm for researching the oscillation modes of system, and to apply a novel method-modal series method, for analyzing the mechanism of "the super low frequency oscillation" in interconnected power networks. |
