Steady-state and transient analysis of transmission lines by using state-space techniques

ABSTRACT STEADY-STATE AND TRANSIENT ANALYSIS OF TRANSMISSION LINES BY USING STATE-SPACE TECHNIQUES MAMÎŞ, Mehmet Salih M.S. in Electrical and Electronics Eng. Supervisor: Prof. Dr. Muhammet Koksal September 1992, 103 pages In this study, the steady-state and transient analysis of transmission lines using state-space technique is investigated. Transmission lines are considered as the interconnection of many lumped parameter sections. By this approach state-space equations are formulated for the system choosing the capacitor voltages and inductor currents as the state variables. These equations are solved using state- space techniques to compute steady-state and transient analysis of transmission lines for different source and load terminations. Both the formulation and solutions steps are programmed in Fortran language to be handled by a digital computer. To illustrate the prepared program and to sight different aspects of the lumped parameter approach several examples are carried out. When it is compared with other methods, it is shown that this method has some superior properties cited in the conclusion section of the thesis.
