Electromagnetic transients in overhead lines considering frequency dependence and corona effect via the method of characteristics

In order to take into account the frequency dependence of transmission line parameters, the propagation equations with transient parameters have to be solved. In this work these equations are integrated by means of the method of characteristics and a convolution procedure using synthesized rational functions. The effects of corona are included using voltage-dependent shunt capacitances and an iterative process in the finite difference solution of the line equations.
