Abstract

In order to identify the chipping fault characteristics and related fault characteristics of planetary gear in wind turbine transmission system, dimensionless dynamical equations of wind turbine gear transmission system which contains a two-stage fixed-axis gear and a one-stage planetary gear were established. Contrasted the fault characteristics of system in normal condition and having planetary gear chipping fault condition with the excitation frequency changed. The paper shows the phenomenon of separation-collision, the fault characteristics and related fault characteristics caused by the chipping fault of planetary gear. According to the simulation results identify the related fault signals caused by the planetary gear chipping fault which cannot be determined in the experimental signal to diagnosis the planetary gear chipping fault.

Key words
