Abstract
In view of the energy crises caused by the growing consumption of electric energy and the instability of the rain regime, which supplies flooded areas of hydroelectric plants, wind energy is highlighted for having an unlimited, renewable, and decentralized source, being considered a clean way of obtaining energy. Base of wind energy, the wind turbine, also called aerogenerator, is mainly composed of blades, hubs, gearbox, generator, nacelle, tower, and foundation. A set of wind turbines is called a wind farm and there are two species of them, onshore and offshore. Onshore wind farms are located on land, close to the seacoast or inland, and offshore wind farms are installed at sea. Its installation must be done outside the migratory routes of birds in the region, to avoid the collision of these animals. Maintenance as a strategy to increase the availability of assets and to ensure the capital invested allows the offer of more competitive products, which benefits companies and the population. Based on this strategy, it is essential to adopt tools and techniques for maintenance management, such as Lean Service. Such a technical concept consists of the application of lean services, which aim the optimization of processes, resulting in zero waste. Tools of this technique can be applied to wind turbines, such as Standardization, Operator Balance Graph and Paretto's Digram. Such elements increase the quality of service and the delivery of results to the organization, while reducing maintenance costs and waste. The main objective of this article is to propose a new model for the execution of preventive maintenance of onshore wind turbines, using the fundamentals of Lean Service. With the application of Lean Service tools, it is possible to present a new model of preventive maintenance, which reduces the likelihood of equipment failures and the risk of energy shortages in certain locations.
