Abstract

The paper analyzes the structural schemes and parameters of simulation models of a number of components of wind power plants (wind turbines) connected to the power system. One-parameter and two-parameter aerodynamic models of an aerodynamic module, a two-mass model of a mechanical module, and models of wind turbine generators of types 3 and 4 are presented. For a twoparameter aerodynamic model of an aerodynamic module, a complete mathematical description and examples of approximations that can be used to determine the parameters of the aerodynamic model in specific variants in the manufacture of wind turbines are given. The structure with the description of the parameters determined by the type of wind turbine for the two-mass model of the mechanical module is given. The structure and parameters of generator models for type 3 wind turbines with an asynchronous generator with a stator directly connected to the power system and a rotor connected via an electronic converter are given; for a type 4 wind turbine with a synchronous and asynchronous generator connected to the power system via an electronic converter. The structure and parameters of the rotation model of the reference frame are given. Regulatory recommendations are given to manufacturers of wind turbines for determining the parameters of module models, depending on the variant of wind turbine models, and to software developers for calculating the initial state, taking into account the necessary parameters provided by the manufacturer.
