| Abstract: | The frequency dynamics measurements in both the Eastern Interconnection of the United States and the Sichuan-Chongqing Power Grid of China are given, and the space-time characteristics of frequency dynamics are analyzed. The fundamental methods and important conclusions for frequency dynamics are discussed, and the shortage of current methods is clarified. This paper theoretically explores the frequency dynamics in large power systems with a method of elctromechanical wave, resulting in the frequency wave equation and its dispersion relation, and hence putting forward a novel method for analyzing the space-time characteristics of frequency dynamics. |
