Zhukov A. Mathematical models and devices for automatic control of complex electrical wind vertical axis of rotation

The object of this study is to wind Electrotechnical complex vertical-axis wind wheel. The purpose of the study is to improve the efficiency of the wind flow wind electrical complex, through a system of automatic control of this complex on the criterion of selection of the maximum power. To achieve this goal we used the following methods: methods of control theory to create a mathematical model of the wind wheel with the vertical axis of rotation and structure of the automatic control system of the WEC, the methods of fuzzy logic controller for the synthesis of structure, methods of electrical engineering for the design development of the electromechanical transducer of wind energy into electrical energy . Scientific novelty lies in the fact that: the first control law is designed to control the excitation current of wind electrical complex with direct conversion of wind energy into electricity, which makes it work at maximum power take-off wind wheel, improved mathematical model of the wind wheel with the vertical axis of rotation in the dynamics, In contrast to the known laws of control allows you to create wind power plant and provides an opportunity to optimize its operation; improved mathematical model of control systems with complex electrical wind vertical axis wind wheel with the use of fuzzy set theory, which improve the quality of the output voltage of the wind electrical system; was further developed an approach to the construction of a combined wind electrical excitation regulator complex, which is to combine the advantages of precise and fuzzy control laws and ensures the most efficient management of a wide range of wind speeds. The practical value is as follows: A control system of automatic control of wind-electrical complex, taking into account atmospheric effects, which is a combined control, consisting of the PI controller and fuzzy controller, working alternately, depending on the speed of the wind flow, which allows for simultaneous control of wind electrical complex as a function of voltage and maximum power take-off, to adapt the model of the automatic control of the generator current WEC in the environment Matlab Simulink, which allows to obtain the parameters for the adjustment of controller set point voltage multiplier inputs and the desired mode of selection of capacity, developed a block diagram of microprocessor-based device and algorithm of its Work to implement the functions of the controller of the automatic control of electrical current excitation of the wind set-based controller with Fuzzy Logic, which allows greater flexibility and simplify the debugging process of the proposed system, implemented a pilot wind power direct conversion of wind energy into electricity with a vertical axis on which the checks carried out theoretical provisions. The degree of implementation - results of the thesis introduced in the Planning and Design Technological Bureau "Concord", Dnepropetrovsk, and in the educational process Vinnytsia National Technical University. Sphere (region) using the results of the thesis - the companies developers, manufacturers and ekspluatatsionschikah wind power plants.
