Panorama da operação e manutenção de parques eólicos no Brasil

Abstract

According to the Associação Brasileira de Energia Eólica (ABEEólica), the installed capacity of wind farms in Brazil reached the mark of 21.6 GW at the end of 2021, with 795 wind farms and 9,176 wind turbines in operation, reaching the second position in the matrix of Brazilian electricity. The operation and maintenance (O&M) phase stands out in the sector, as it is responsible for ensuring the safe and reliable operation of wind farms. In this context, the present work aims to analyze the panorama of the O&M sector of onshore wind farms in Brazil, to show the importance of O&M management in the performance of the plants. First, through a literature review, the fundamentals of wind-electric generation and the subsystems that make up a wind complex are presented. Subsequently, aspects such as organizational management, maintenance planning, contract management, supply chain and operation monitoring, which impact the performance of O&M management, are discussed in a comprehensive manner. The main advantages and disadvantages of the maintenance methods applied to parks are presented, based on the costs and efficiency of maintenance activities, including the

costs of labor and spare parts, quality of maintenance execution and the cost of non- generation, caused by due to the unavailability of the subsystems. Finally, a set of

indicators for performance analysis is proposed, grouped by the Financial dimensions (5 indicators), Energy Generated (8 indicators), Operation and Maintenance (5 indicators) and People (2 indicators). Thus, it is concluded that good management is capable of minimizing costs and optimizing the performance of O&M activities, without compromising the operational efficiency of wind farms.
