Digital Calculation of Transient Phenomena in EHV Systems Part I

A method of computing switching transients using a finite difference scheme is presented. The scheme proposed here has the facility of accommodating any termination (including nonlinear elements like lightning arrester). Hence this method is an improvement over the method suggested by Stafford, Evans and Hingorani. Further this method can be used for the determination of the transients arising out of different types of electrical disturbances in the system i.e. component flashover, faults, lightning strokes etc. The stability analysis of the scheme proposed and the computational aspects of the procedure are discussed.
