In the early 2000s, due to the lack of rainfall in hydroelectric power generation sites in Brazil, the need for the search for new sources of energy arose. The Incentive Program for Alternative Energy Sources (PROINFA) was created in mid-2002, bringing significant investments in alternative sources of energy - especially renewables - with a view to diversifying the Brazilian energy matrix and, at the same time, contribute to reducing the effects of global warming. In the face of its abundant natural resources, the use of the Brazilian wind potential is accelerated. It was observed that a large part of the wind turbine manufacturers and other components of the wind farms installed in Brazil come from countries with different climatic conditions and culture of wind farms (from component manufacturing / power generation to operation and maintenance) already mature By the end of 2018, Brazil had 601 installed wind farms, much of it in operation since 2010. Exploratory studies indicate that failures in these wind farms have increased, reducing the availability of electricity generation. This dissertation aims to propose guidelines and good practices for the management of the operation and maintenance of wind farms in Brazil. The research method can be characterized as a predominantly exploratory research, of applied nature and inductive character, with a predominantly qualitative approach. Field research included the study of cases in ten wind farms. The research procedure included three steps. In the first stage, a traditional bibliographic review was performed on the structure of a wind farm, as well as its operation and about maintenance management, involving types of maintenance, characteristics and applications, as well as maintenance management strategies and tools to aid analysis of failures and decision making; and a systematic bibliographic review regarding the operation and maintenance of wind power plants. The second stage covered the case study. The third step consisted of the analysis of data already treated using tools to aid in the analysis of failures. As a result of the dissertation, we present the proposal of guidelines and good practices for the operation and maintenance of wind farms, grouped in the following components: i) wind turbine, ii) medium voltage circuit, iii) elevating substation, and iv) others.
