Abstract

The authors stressed the importance of emergency braking systems for wind turbines. These braking tools should be embedded in wind turbine design as the expansion of the main control system. The research group considered electromechanical device with automatic and manual modes to solve this problem. The device with small overall dimensions transmits high braking torque with the help of specific kinematic parts combination and waveform gear reduction unit. The specific feature of the braking system is the ability of its integration into the wind turbine construction without significant changes. The authors discussed the electrical drive control system on the basis of functional chart. System stability was analyzed using Mikchailov criterion plotting the hodograph of third order performance equation.
