Abstract :
The frequency dependent line model (also known as the J. Marti model) which is currently used in most electromagnetic transient programs, is very efficient and accurate for most simulation cases. However, it makes an approximation in choosing the modal transformation matrix that is used to switch variables between the phase and modal domains at each simulation time step. This approximation may not hold true for certain tower configurations and/or conductor types where line parameters vary drastically with frequency. In this paper, a wavelet based alternative solution, which incorporates frequency dependence of transformation matrices into the simulation process is presented
