Control characteristics of a dual input generator set

The article considers a dual input generator set (DGS) for power supply of various facilities. The subject of the article is the characteristics of DGS obtained by implementing a mathematical model DGS is an electromechanical energy converter with several conversion stages. For the mathematical description of the DGS properties in dynamic modes, the model of a generalized electromechanical energy converter is used, which makes it possible to take into account all the connections in the DGS under study. The use of the theory of a generalized electromechanical energy converter, which is based on a combined approach, including the theory of electrical circuits and field theory, makes it possible to study electromechanical energy converters both in dynamic and steady modes. It is for the purpose of converting two dissimilar types of energy into three-phase alternating current energy that the Federal State Budgetary Educational Institution of Higher Education “Kuban State Technological University” developed two-input generator sets (DGS), which allows summing up the energy of two dissimilar renewable energy sources in one electromechanical energy converter to generate electrical energy. To study the parameters and characteristics of such installations, a mathematical model was created, on the basis of which a computational experiment was carried out, which made it possible to get an idea about the object under study. The task of mathematical modeling of the DGS was to obtain its dynamic characteristics and, on the basis of these characteristics, to obtain the regulating characteristics of the DGS, such as: the dependences of the voltage and frequency of the output voltage on external factors and the parameters of the DGS. The external factors affecting the operation of the DGU include: the rotational speed of the wind turbine rotor, which depends on the wind speed, and the voltage at the output of the photoelectric converter, which depends on the intensity of solar radiation. The parameters of the diesel generator set that affect the operation of the installation are the parameters of the windings of individual parts of the diesel generator set.
