Целью работы является определение зависимостей величины кратковременных превышений мощности на выходе ветроэнергетической установки с аэродинамическим мультиплицированием, возникающих в ходе электромеханических переходных процессов при применении моментного способа управления, от характеристик электромеханической системы и ветрового потока. Решение поставленной задачи проводилось с использованием модельного эксперимента. В качестве инструмента исследования в работе была использована математическая модель электромеханической системы ветроэнергетической установки с аэродинамическим мультиплицированием. В результате получены временные зависимости отклика моделей в виде временных зависимостей мощности на выходе электромеханической системы ВЭУ. Полученные зависимости могут быть использованы при выборе параметров электрооборудования ВЭУ с аэродинамическим мультиплицированием и моментным управлением.
The purpose is to determine the dependencies of the value of short-term power excesses at the output of a wind power plant with aerodynamic multiplication that arise during electromechanical transients when applying the moment control method, on the electromechanical system and the wind flow characteristics. The dependence of super nominal emissions of the output power of a wind power plant with aerodynamic multiplication and moment control on the characteristics of the wind flow was studied for the first time. The mathematical models synthesis method of multi-channel wind-generating complexes proposed by the authors was used in the paper. Solution of the problem was carried out with using a model experiment. The wind turbine with aerodynamic multiplication mathematical model synthesized using the technique proposed by the authors earlier. The input of the wind turbine mathematical model was feeding by the wind flow as a function of time, which included a trend component and a sinusoidal component with given parameters. During the model experiment, the models time dependences of the response, as a time dependences of the output power of the wind turbine electromechanical system obtained. The simulation results in the form of graphs and in the form of an approximating expression presented. The obtained results can be used for calculating the installed capacity of electrical equipment for wind power plants with aerodynamic multiplication and moment control, taking into account the overloads that arise during the electromechanical transient process.
