Overview of major faults in wind turbine components

Renewable energy is seen as the greatest solution for meeting growing energy needs. Wind energy is regarded as a rich energy source, and it frequently coexists alongside solar energy. In comparison to fossil fuels, it is inexhaustible and pollution-free. Based on its purpose and energy producing yield, wind turbines are frequently classified as small or large systems. This paper will present an overview of all possible faults in a wind turbine from structural damage to electrical fault. To improve the system's reliability, sustainable materials and advanced technologies for the development of various parts of wind turbines are being supported. Turbine blades, generators, and other auxiliary parts play an important role in the turbine's smooth functioning. Thus, their material properties are paramount. Hence, an overview of different parts, their yearly corresponding faults and their breakdown causes, are presented in this paper.
