Resumen:
The present work aimed to present a digital method, based on space-state analysis techniques, to study dynamic overvoltages in EHV power systems due to rapid charge rejection. It was demonstrated the convenience of the L-representation for the equivalent circuits of the transformers and verified the behavior of the system with linear reactors at the ends of the transmission line. The effect of transformer saturation was also observed. The last chapter is devoted to the presentation of the equations to be used in a possible simulation for the unbalanced three-phase case.
