Development of a power control model for the wind plant by pitch angle for training purposes

The problem of arranging a practical education in automatic control of renewable power plants is considered. It was noted that a wind power plant (WPP) is one of the most complex objects of automatic control. An overview of educational dynamic models of WPP is given. A simplified nonlinear dynamic model comprising the power control circuit by adjusting the pitch angle was proposed for practicum in the course of Automatic control and protection of power plants with renewable energy sources. Functional and structural diagrams of an automation control system are given. Approaches to development of a dynamic model in Matlab/Simulink environment and methodology of practical education with its use are described. A series of numerical experiments with a model for the study of dynamic processes in a wind power plant control in the modes of switching on, shutting down and reaction to a wind gust during normal operation is proposed. Time diagrams obtained during these experiments are presented. Ways of further improvement of the model are proposed.
