A Fybrid Computer Study of a DC Power System: I

A hybrid Computer, a direct combination of a digital and an computer, is used to simulate a dc power system. To achieve maximum computing proficiency the simulation is arranged so that the distributed parameter transmission system is represented on the digital computer while the analog computer is employed to represent the 6-phase converters. Results of a computer study are presented wherein system faults and parameter variations are considered. Also, a comparison of results obtained from a hybrid computer study and those obtained using the University of Wisconsin ac/dc system simulator is presented. It appears that the hybrid computer may be conveniently employed to study a large number of power system problems which heretofore have been limited to model studies.
