Application of z-Form to the Solution of Swing Curve

Introduction The z-form, (1-3 ) method of analysis is an out-growth of z-transform mathematics and is a numerical method of obtaining the response of continuous linear or non-linear systems. The solution is obtained as a time series representing the value of the response at equally spaced intervals of time. The method is ideally suited to the digital computer approach to the solution of power system problems. The inverse Laplace transform ofa given function C(s) is
