Study on synthesis fault diagnosis strategy of the brake system of wind turbine based on evidence theory

Abstract

Wind turbine is a large and complicated machine to gather the machine, electricity, liquid in the integral whole, the brake system is importance constitute the part of wind turbine. therefore, opening the fault diagnosis of brake system is very important meaning. Jamming of cartridge is an important bottom thing to fault tree, because the circumstance is complicated, how to fault with the computer intelligence judgment jamming of cartridge, did not have the fit solution up to now. This paper adopt wavelet theory, fuzzy neural network, evidence theory etc. tool, proceeded the experiment research to jamming of cartridge fault diagnosis of wind turbine break system. It according to evidence theory, we proceed the analysis and discuss to the support of the proof and proof conflicts of synthesize fault diagnosis. © 2011 Springer-Verlag.
