RESUMO:

Humanity's need for electricity is increasing. According to Anuário Estatístico de Energia Elétrica (Statistical Yearbook for Electric Energy) of 2016 by Empresa de Pesquisa Energética (Energy research company), there was an average annual growth of approximately 3% in electricity consumption in the world from 2008 through 2012. With demands growing, the search for renewable energies with the least possible impact on the environment is pressing. Among those energy sources, the wind appears as one of the most viable considering a less negative impact on the environment. Currently there are several topologies of wind turbines, each one with their advantages and disadvantages. Most of them use gearboxes and electronic converters. However, a new topology was recently designed by UFRN researchers,Regulador Eletromagnético de Frequência (Electromagnetic Frequency Regulator – REF). It makes the use of gearboxes unnecessary and does not use electronic converters between the generator and grid, but keeps the frequency and voltage constant in the network. The present work aims at carrying out a dynamic simulation of disturbances in the electric network like load rejection and symmetric or asymmetric defects in a wind farm that comes to use REF in its generation topology. Those simulations are aimed at meeting the minimum requirements of Procedimentos de Rede (Network Procedures), concerning the ride-through capacity established in Brazil by Operador Nacional do Sistema (National System Operator – ONS), in sub-module 3.6. The simulations will be done on Real Time Digital Simulator (RTDS), which is a computational platform (hardware and software) for real-time operation of transient electromagnetic and electromechanical phenomena, focusing on electric power systems.
