The object of research is the processes of occurrence, perception, and redistribution of loads in the structure of a removable module for the situational adaptation of the flat car, model 13-7024, to the transportation of strategic cargoes. In order to transport strategic cargoes, including military equipment, agricultural machines, etc., the use of a removable module is proposed on the flat car. Appropriate calculations were performed to determine parameters for the structural components of the removable module. At the same time, the profile of the frame was determined by the value of the maximum bending moment acting in its cross-section. The thickness of the sheet, which forms a horizontal plane for placing the load, was calculated according to the Bubnov–Galyorkin method. To substantiate the determined parameters of the structural components of the removable module, its strength was calculated. The calculation results showed that the strength of the removable module under the considered operating load schemes is ensured. A feature of the research results is that the use of the proposed structure of the removable module makes it possible to expand the range of goods transported by flat cars without improving them. The field of practical use of the results is the engineering industry, in particular, railroad transport. The conditions for the practical application of the research results are the use of variable height fittings in the removable module. Our studies will contribute to devising the recommendations for increasing the efficiency of the operation of flat cars through their situational adaptation to the transportation of strategic cargoes. In add, the results could prove useful for the construction of modern structures of modular vehicles

The article presents the results of a study of the dependence of the quality indicators of electricity generated by solar power plants in three-phase electrical networks on the level of generated power. In the course of the study, it was established that when the generated power is reduced, the grid voltage inverters that are part of the solar power plants cause an increase in the share of higher harmonic currents to the electric grid. An analysis of international standards regarding the quality requirements of the generated current was performed, which showed that when the level of generated power decreases, the quality of electric energy decreases and may not meet the requirements of the standard. The algorithm of frequency-adaptive pulse-width modulation is proposed, which allows to improve the quality indicators of the electricity generated by the grid inverter of the voltage of the solar power plant to the electrical grid.
