Wind Turbine Faults, Faults Diagnosis and Fault Management Systems: A Review

Abstract

Wind power generation is motivated by environmental concern and exhaustion of fossil fuels. It is gradually becoming an irresistible source to meet the demands of green energy. Wind energy systems are complex structures and vulnerable to many possible faults. The fault detection at initial stage of occurrences of faults can lead to increase the performance of the wind energy systems and reduce the failures. This paper gives the comprehensive review of fault occurrences in wind energy systems, its diagnosis and recent progress in the fault management systems: condition monitoring (CM) systems and fault tolerant control (FTC) systems. The main objective of this study is to realize the existing methods for required levels of efficiency, reliability, and availability in high-capacity wind energy systems.
