A computer model of the hybrid compensator of fast varying loads was developed in this dissertation. The computer model was implemented in MFC Visual C++ compiler version 6.0. The classification of fast varying loads and effects of their operation in distribution systems were described in this dissertation. The power properties of fast varying loads were expressed in terms of the Currents' Physical Components Theory. Therefore, the Currents' Physical Components Theory was applied to systems with non-periodic voltages and currents. The supply current of the fast varying loads was decomposed into the useful and the useless components using an algorithm based in the Currents' Physical Components Theory. The current components resulting from this decomposition were used to generate the reference signals for compensator control. The systems of equations that modeled the integrated operation of the distribution system, the fast varying load and the hybrid compensator were developed in detail. The computer model was developed with sequential subroutines that allowed both the analytical solution of the compensation of fast varying loads and the incorporation of the hybrid compensator in the compensation of fast varying loads. The performance of the computer model was verified by comparison between the analytical results with the results obtained with the effect of the hybrid compensator. Finally, the computer model provided reduction of the active and reactive power variation and reduction of the distorted component of the supply current of the fast varying loads tested.
