Summary
Natural power transporting capacity of overhead transmission lines in high voltage level and above is defined mainly by their source impedance loading (SIL) level. Lines with augmented power capacity are denominated as high surge impedance loading (HSIL) lines. In this paper the transient behavior and main characteristics of HSIL lines created using a new methodology for optimizing overhead transmission lines are analyzed. Three different lines for 500 kV systems are considered: a conventional line and two non-conventional lines. The first HSIL line has 1331 MW meanwhile the second 1429 MW. In those lines were performed simulations for: line energization, load rejection, line-to-ground fault and three phase fault. Result shows an important SIL increment and cost reduction for optimized lines. Furthermore, transiente overvoltages of test systems are similar.
