Análise de Sensibilidade de Parâmetros Elétricos de Linhas de Transmissão Dependentes na Freqüência

Abstract

Abstract: In this work a large sensitivity analysis of longitudinal and transversal electrical parameters of a three-phase transmission line in frequency domain was performed. An actual 440 kV transmission line was used as reference. In sensitivity analysis, the following line characteristics were varied: ground wires diameter, phase conductors diameter, height of conductors, horizontal distance among phases and vertical spacing within external phase bundle. For each line characteristic, the performance of electrical parameters in frequency domain, in terms of primitive andmodalmatriceswas observed.
