    To have a bigger knowledge about renewable energies we have made a study of the most important energies, the ways of exploitation, the nowadays technologies, data of implantation, laws and advantages and disadvantages. The most important part of this study is related to the wind energy due to we made the second part of the project of a wind turbines installation and the different elements to connect them to the net. After these we have made the study of the technical aspects that we need to take care for the implantation of a wind park in the province of Pleven (Bulgaria), more concrete, in the local town of Baykal. The park is an alignment of three turbines of 600 kW of unitary power. The energy that we have calculated that we will produce is around 3.6 GWh per year, with 2218 equivalent hours of annual efficiency. In this part of the project we have boarded first the viability of the wind park location from the wind data of the area. These data have been studying technically to known the potentiality of it and have could decide the best turbines to use there. Also, we make an important study of the elements necessaries to the turbines connection to the net, the transformation centers, the protections of them, the types of wire that connect the elements and the switchgear necessary for this kind of installations. The project has three principal parts interrelated: first, the introduction and the study of the most important renewable energies, then, the wind park memory where we have included the technical aspects and the calculations, and finally the planes, the part most visual.

    Wind farm project
    (2016) Sastre Gómez, Ana; Malanda Trigueros, Armando; Tzvetkova, Svetlana; Escuela Técnica Superior de Ingenieros Industriales y de Telecomunicación; Telekomunikazio eta Industria Ingeniarien Goi Mailako Eskola Teknikoa; Technical University of Sofia (Bulgaria)
    La energía eólica ha experimentado un incremento significativo a lo largo de toda Europa, incrementando la importancia de las energías renovables como un recurso energético. Con el fin de posicionarlas como las principales, deberían estar reguladas con un marco legal que garantice la viabilidad económica de estas instalaciones y hacerlas atractivas para los inversores. Durante los últimos años los mayores avances en la eficiencia de las turbinas eólicas es en el uso de vientos menos intensos, que son comunes en la zona donde se realiza el Proyecto. El objetivo del proyecto es la construcción de un parque eólico y se encuentra en la costa del Mar Negro en Bulgaria, concretamente en la ciudad de Suvorovo. Consiste en una alienación de quince aerogeneradores de 2 MW cada uno, lo que supone una potencia total de 30 MW.
