Analysis of systems and methods of emergency braking of wind turbines

Abstract

Increased wind loads in the world and the lack of human control over the operation of wind turbines create high risks of their operation. The most common accidents in the operation of wind turbines are: the destruction of the blades due to the excess of the rotor speed, overheating of the generator windings, the destruction of the structure due to increased vibrational vibrations. As a rule, braking systems are used in wind turbines to prevent the listed negative factors. This article discusses wind turbine power control systems, control systems and braking systems, since each type of these systems has its own specific and narrowly focused task. The article also presents the results of the search and analysis of existing systems and methods of emergency braking of WEI.
