Modelovanje impedanse zemlje kao povratnog provodnika / Modeling of Earth return path impedance

Description

<p>U radu je pokazano da frekvencijski zavisna impedansa<br />zemlje kao povratnog provodnika, pri proizvoljnoj<br />učestanosti može veoma tačno da se odredi pomoću<br />fluksa kompleksnog Pointingovog vektora. Za<br />izračunavanje kompleksnog Pointingovog vektora,<br />neophodno je prethodno odrediti raspodelu struje u<br />zemlji, kao i raspodelu magnetskog polja i u zemlji i u<br />vazduhu iznad povr&scaron;i zemlje. Obe ove raspodele takođe<br />su značajne za analizu elektroenergetskih sistema.</p> / <p>The thesis shows that the Earth return impedance at<br />arbitrary low frequency can be accurately determined<br />from the complex Poynting vector flux. For the complex<br />Poynting vector calculation, first it is necessary to<br />determine the current distribution inside the ground, as<br />well as the magnetic field distribution both inside the<br />ground and in the air above the ground surface. Both<br />distributions are also significant for power electrical<br />systems analysis.</p>
