Modelagem e simulação aerogerador auto excitado conectado à barra infinita através de duas linhas de transmissão.

Abstract

The continuing global concern about the environment and the emission of fossil fuels into the atmosphere has made the study of new alternative sources of energy very important. Among the various sources of energy, wind stands out because it is renewable, inexhaustible and perennial. The main problem of wind energy is the cost which although decreasing, is still high compared to other energy sources. For example, in Brazil in 2008, the cost per MWh generated from wind farms was around 2.3 times greater than that generated by hydroelectric plants. Another interesting fact is that about 50% of the total of this wind power generation potential is in the northeast. In this way, the development of research works in order to assist the operation and stability of the wind system connected to the national interconnected system are of fundamental importance. In this context, this work proposes the simulation of the generation system with wind turbine connected to an infinite bar through two parallel transmission lines. Carrying out the modeling of the system and characterizing the dynamic and permanent regime with a view to studies to carry out studies of dynamic stability and contingency.
