Abstract
Wind is one of the most important alternative sources of energy, the distinguishing features of which are zero cost and no negative impact on the environmental situation. In view of the increasingly worsening fuel and energy crisis, interest in the use of wind energy has increased significantly over the past few years. Data on the structure of a wind power plant are given. Asynchronous machine with squirrel cage rotor is considered as a generator. A model of an autonomous induction generator is constructed taking into account the nonlinearity of the magnetic circuit. The model for automatic construction of mechanical characteristic of asynchronous machine is also presented. Modeling is performed in the MatLab Simulink environment.
