Mathematical Modeling of Wind Turbine Brake System

The article provides statistical data on accidents at wind power plants over the past 30 years. The necessity of using secondary (emergency) wind turbine brake systems is substantiated. An overview of the existing brake systems for wind power plants is presented - three main types of that systems have been identified. The advantages and disadvantages of the wind turbine brake systems are considered. The authors proposed the use of an electromechanical brake system for wind turbines. A mathematical model of a 3 kW vertically axial wind power plant and a mathematical model of an electromechanical brake system for this wind power plant are presented. The detailed description and interrelation of mathematical models components is given. The conditions for the mathematical modeling of the brake system operation are described. The results description for mathematical modeling of the brake system operation is presented. The advantages and disadvantages of the obtained mathematical model for the wind turbine brake system are considered.
