摘要: Wind turbines proliferation in industrial and residential applications is facing the problem of maintenance fault diagnosis. Periodic maintenances are necessary to ensure an acceptable life span. The aim this paper therefore assess impedance spectroscopy contribution failure diagnosis doubly-fed induction generator-based wind turbines. Indeed, already used for batteries, fuel cells, electrochemical systems. For evaluation purposes, simulations carried-out on a 9-MW farm consisting six 1.5-MW connected 25-kV distribution system that exports power 120-kV grid. In context, two common failures investigated: phase grounding short-circuits. addition, generator stator resistance variation also considered performance
