Abstract :
From the starting point of multi conductor power-transmission-line equations in scattering form in the frequency domain, the paper first summarises the principal aspects of numerical time-convolution and z-transform methods as applied to electromagnetic transient analysis in power-network systems. Against that background, the paper provides a detailed comparative study of the two analysis methods with particular reference to the representation of the nonlinear frequency-dependence of transmission-line parameter sets, multinode-system modelling, storage requirements, execution times, solution accuracy, and algorithm stability.
