Technical Electrodynamics| Резюме: | Increased progress of power systems has led to a structure of close generator groups connected to other groups by weak transmission lines. This has been known to cause oscillations were these groups oscillate against each other in an inter area fashion. This implies that power oscillates between areas and thus diminishes the transmission capability of the interconnected system. This paper describes the identifying modes of oscillations in interconnected power systems by means of using recordings of a Wide Area Measuring System. To detect the dominant oscillation frequency, the Fast Fourier Transform is applied. The algorithm is tested on known test system and results were compared with the results of modal analysis of power system. It is obvious from the analysis that further investigations are necessary to improve system damping. This is an important goal not only to ensure reliable system operation but also to improve transmission capacity of the grid with the existing high voltage lines. References 5, tables 2, figures 2. |
