Abstrakty

EN

In the paper an analytical method for calculation of magnetic field emissions, caused by overhead power line, is dealt with. The obtained results are verified with measurements performed on a 400 kV double-system overhead power line and with numerical calculations using finite elements method. The results obtained by the proposed analytical method are compared with results of calculation where conductor sagging is considered. The proposed method is suitable to be used in optimization procedures where the computational time could have an important role.

W artykule opisano analityczną metodę obliczania emisji pola magnetycznego przez napowietrzną linię elektroenergetyczną. Wyniki porównano z pomiarami przeprowadzonymi na linii napowietrznej dwutorowej 400kV z wykorzystaniem metody elementów skończonych. Proponowana metoda pozwala na dużą oszczędność czasową i optymalizację tego rodzaju obliczeń.
