Faults diagnosis of wind energy conversion chain based on doubly fed induction generator by principal components analysis method

PCA method based on residues analysis has been established and applied on wind energy conversion system based on doubly fed induction generator diagnosis. An accurate analytical model of the machine has been proposed and simulated to perform the healthy and faulted data for PCA approach need. Several representations of the …

Strategy for enhancing reliability and lifetime of DC-AC inverters used for wind turbines

Lifetime of wind turbine inverters is below expectations therefore. novel design and drive strategies are timely required to achieve optimum life span. In this work. a novel driving strategy to mitigate stresses on inverters is proposed. First. an electro thermal analysis was carried out using finite element modelling methods. Subsequently. …
