Özet

Transient overvoltages and ovecurrents arise following a switching phenomenon in electric power systems. Consequently, high electric fields occur because of the modified electrical patterns. These fields create several inconveniences both for the environment and for the human life. Theoretical field analysis is a complex and a difficult problem. This paper presents a new evaluation procedure for electrical transients occurring while switching an unload power transmission line. The proposed simulation is applied for an unload transmission line connected between KEPEZ and YATAGAN in 380 kV Turkish National Power Transmission Systems. Frequency dependent T model is used for the simulation of the line. Instantaneous transients during the first cycle following a disconnection of the line are evaluated by using EMTDC/PSCAD Software. Moreover, the effects of transmission line length are also analysed.
