Procedimiento para el estudio de transitorios electromagnéticos de maniobra a nivel de subtransmisión aplicado al sistema de subtransmisión de la EEASA utilizando el programa ATP-EMTP.

Abstract

The present work of curricular integration is composed of three chapters which have been developed as follows: In chapter one there is an introduction to the overvoltages produced by electromagnetic transients, definition, classification, causes, effects and the importance of their study. There is also a brief review of the mathematical model of the traveling wave, which is the fundamental basis for the study of electromagnetic transients. Chapter two describes the fundamental components of an electrical system and the mathematical models of the ATPDraw software suitable for the realization of electromagnetic transient studies in electrical power systems. It also establishes the guidelines to be followed when entering the parameters of each of the models in ATPDraw. In chapter three, a description of the electrical network of Empresa Eléctrica Ambato S.A. (EEASA) is made, it is considered that the distribution feeders are modeled as loads, while at the subtransmission level the network is completely modeled. Once the network is modeled, case studies are established to simulate electromagnetic transients produced by the energizing maneuver of transmission lines, transformers and compensators that are part of EEASA's network. The results are evaluated and a procedure is proposed for the study of electromagnetic transients of maneuvering at subtransmission level with the purpose of reducing the impact of electromagnetic phenomena on equipment.
