Computation of transmission line transients by using fast inverse Laplace transform (Q1273269)

Summary: Transients appearing in power transmission systems due to line energization are computed by using the fast inverse Laplace transform (FILT). The \(s\)-domain transfer function of the system is calculated by using a distributed parameter representation of the transmission line. For the frequency to time domain transformation of the transfer function, the fast inverse Laplace transform is applied. Comparisons are made between the results obtained by the FILT and conventional methods such as the conventional Laplace transform and the electromagnetic transients program.
