Abstract [eng] |
Determination of switching-on overvoltages in power transmission line is important factor for designing system insolation. A recurrent mathematical model based on electromagnetic surge phenomena and Bergeron line model theory was designed for calculating switching-on overvoltages in complex configuration high voltage transmission line. A research of switching-on overvoltages dependence on various parameters using designed power transmission line model was carried out. It was determined, that switching-on overvoltages are influenced by system phase angle, impendance and voltage level. Furthermore, it was determined that transmission line switching-on overvoltages has a complex dependence on power transmission line sections length, number of branches, location, length and number of power cable insertions. What is more, it was determined that a variation of a wave inpendance has a small influence on switching-on overvoltages which may be neglectend in a approximate calculations. |
