Features of the use of elements of integrated hydroelectric facilities in conjunction with solar photovoltaic installations

Abstract

The prospects for the use of solar power plants in the world of environmental hydraulic engineering are analyzed. Recommendations on the constructive combination of elements of structures of environmental hydro technical complexes with solar photovoltaic installations (SFEU) are presented. The variants of their most rational location on the building of hydroelectric power stations (GES) of different types are considered. It is established that the buildings of small and medium-sized hydroelectric power plants represent significantly more constructive possibilities for combining the GES building with the SFEU. The relationship between the area suitable for placing solar cells and the diameter of the turbine impeller is determined. With a decrease in the diameter of the impeller, the relative surface area suitable for placing solar cells increases. It is noted that it is most appropriate to combine SFEU and small hydroelectric power plants with non-combined buildings with transformers on the downstream side. At medium-sized hydroelectric power plants of various types, the conditions for combining are approximately the same. The results of the work can have an impact on obtaining a reliable power supply system based on renewable energy sources, improving the safety of the GTS (hydro technical structures) of existing hydroelectric facilities in the context of increasing the efficiency of the introduction of ”green“ technologies in the energy sector while reducing biosphere pollution and greenhouse gas emissions, including in hard-to-reach areas of agricultural areas where there are problems with centralized water supply.
