Efficiency Analysis of the Friction Material for the Wind Turbine Braking System

Abstract:

The paper presents a research in identification of optimal conditions for friction material operation in the wind turbine braking system. The component composition of friction material includes brass (binder material); steel (fibers); iron oxide (fillers); cuprum, graphite and metal sulphides (friction modifier); aluminum (abrasive). The dependence of its frictional characteristics on the operating temperature is presented. We also presented the simulation of several modes of the wind turbine braking system. The most optimal operation mode for the friction material is the wind turbine rotor braking and its retention for 30 seconds, followed by further retention of the wind turbine rotor for 300 seconds after each 4th braking.The temperature of frictional material with these parameters did not exceed 350 oC, though the minimal idling of wind turbine was provided.
