La investigación responde al problema ¿Cómo Influye el motor de CA en la Pala Eléctrica 4100XPC en la mina Cerro Verde - Arequipa?, como objetivo pretende, determinar la influencia del motor eléctrico de CA en la Pala Eléctrica 4100XPC en la mina Cerro Verde – Arequipa y como hipótesis se asume que el motor de CA influye positivamente en la Pala Eléctrica 4100XPC en la mina Cerro Verde - Arequipa. El diseño fue el descriptivo correlacional, en la muestra de los resultados del funcionamiento dela pala eléctrica 4100XPC mediante el motor eléctrico en CA, a quien se aplicó la experimentación, basado en el análisis de criticidad que permitió mejorar la confiabilidad operacional los equipos en la minera Cerro Verde. Concluyendo que el procedimiento del el motor de CA Influye positivamente en la Pala Eléctrica 4100XPC en la mina Cerro Verde – Arequipa la cual permite obtener niveles seguros de funcionamiento y productividad dentro de cada área de trabajo de la Pala eléctrica 4100XPC, también el estudio correlacional permitió confirmar una influencia positiva entre el motor de corriente alterna y la Pala eléctrica 4100XPC en la mina Cerro Verde Arequipa, lo que nos indica que a mejor funcionalidad de la corriente alterna mejor rendimiento de la Pala eléctrica 4100XPC.

A detail modelling of railway electrical system with energy storages devices is developed in this thesis in order to analyze most of the implemented railway electrical system. The modelling has been realized from a point of view the design of them as from a point of view of purely energetic efficiency. In this way, after analyzing of the electric railway systems, it has been developed simple element models that have been grouped in four categories: contact line and return circuit, fix elements, mobile elements and energy recovery and storages devices. The complete systems are built from the simple element models linked. The system of equations of the complete system is no linear, and it is solved means of numeric methods. Then, it is shown the structure of Rsim software that has been developed completely as a part of this work, to conclude with two examples of the application of Rsim. The first example belongs an alternative current railway electrification and the second example is a direct current railway electrification. Keywords: DC railway system, AC railway system, railway modeling, energetic efficiency, reverse substations, energy storage devices, unbalance, rail potential, stray currents.
