“…For simple simulations with constant parameters, a model can be applied based on cascades of π circuits. Considering frequency dependent parameters, cascades is used with modified π circuits [4,5,28,29]. The modified π circuits are obtained from classic π circuits used for simulating introductory cases with frequency independent parameters [29].…”

“…Heun's method, or trapezoidal rule, transforms sets of differential equations into sets of algebraic equations [3]. However, it is prone to sudden changes in values used for its application [4,5]. Because of the simplicity and better accuracy than Euler's method, the trapezoidal rule is chosen for the application in Electromagnetic Transient Program (EMTP) and Alternative Transient Program (ATP) [6].…”

“…The infinitesimal unit model of transmission lines can be represented by a lumped-parameter π equivalent model.

Abstract-Simulations of electromagnetic transients in transmission lines can be carried out using simple circuit model. In the case of applications of simple circuit models based on π circuits, there are problems mainly caused by numeric oscillations. The lumped-parameter π equivalent model can be used with some advantages. The numeric integration method applied to the simulations of electromagnetic transients is the trapezoidal rule. If this numeric method is associated with the π equivalent model, results obtained from the simulations are distorted by Gibbs' oscillations or numeric ones. The introduction of damping resistance parallel to the series RL branch of the π equivalent model can mitigate Gibbs' oscillations in obtained results. Voltage peaks caused by these oscillations can also be decreased. So, in this paper, the combined influences of the introduction of damping resistance, the number of π circuits and the time step are investigated searching for minimizing Gibbs' oscillations and the voltage peaks in electromagnetic transient simulations. For this, transient simulations are exhaustively carried out for determining the highest voltage peaks, ranges of damping resistances and other parameters of the model, which minimize these voltage peaks caused by Gibbs' oscillations.
