Analysis of simultaneous unbalances and transient recovery voltages of power system has been undertaken in this paper. The approach is similar to the one developed in Part I of this paper. The method requires only the assembly of the nodal admittance or impedance matrices of various elements of a power system and subsequent solution of sets of linear algebraic equations subjected to constraints. The transient analysis of a power system having untransposed transmission lines can be carried out by the application of modified Foruier transform and the steady state theory of natural modes. Finally a digital computer can be programmed to calculate the magnitudes of the fault currents and active recovery voltages.
