Development of a computer model of an arc-stator inductor generator for researching electromagnetic processes in stationary and time ranges
Relevance. The construction of thermal power plants, which are environmentally hazardous, is increasingly fading into the background every year, giving way to plants that operate on renewable energy sources, which are essentially endless natural resources. Among such facilities, hydroelectric power plants have the highest efficiency, but their construction on flat rivers in a number of regions of Russia is difficult and dangerous for the environment. It is proposed to use free-flow damless micro hydroelectric power plants based on arc-stator inductor generators as sources of electrical energy. The design features of the generator necessitate the study of the electromagnetic field and the resulting quality of electrical energy and checking it for compliance with domestic standards. To unify the research, it is necessary to create a single methodology for generators of different capacities. Aim. Development of a computer model for studying the electromagnetic field and the quality of the output electrical parameters of an arc-stator inductor generator. Methods. Based on preliminary electromagnetic calculations of several electric machines of different power, 3D modeling is performed based on the finite element method, taking into account geometric features, and recommendations are made on the design of generators for micro hydroelectric power plants. Results and conclusions. The authors have developed a computer model of an arc-stator inductor generator to study electromagnetic processes in the stationary and time ranges, which takes into account the geometric features of the design of the electric machine. The authors studied the quality of the output electrical parameters and developed the recommendations to improve the shape of the EMF curve of the generator anchor winding.
