    Power system analysis on programmable calculators
    Walker, Michael Allen (Virginia Tech, 1974)
    The objective of this thesis is to develop and implement a power systems analysis package for use on minicomputers and programmable calculators. Algorithms for four different load flow techniques are developed and tested on the HP9830A programmable calculator. The transient stability analysis problem is reviewed, with special attention being given to the solution of the system performance equations by either the bus impedance matrix approach or the bus admittance matrix approach. Also attention is focused on the solution of the machine swing equations by the state transition method and by the technique of fourth-order Runge-Kutta. Comparisons are made between the different load flow methods to possibly determine the 'best' method to be used in the analysis package. Comparisons are also made between the methods of solving the swing equations in order to select a preferred technique for use in the stability program.
