Objective: The data on the synthesis of a combined electric power source for a self-contained electric-power system with a diesel generator (turbo-generator) and hydrogen power source was presented in the article. Objective: To justify the structure and parameters of a power channel of a self-contained electric power plant based on power augmentation with parallel operation on the total load of two electric power sources – synchronous generator and hydrogen power source. Methods: Mathematical modeling of the main power processes was applied, including the processes of active and reactive power distribution control in a self-contained electric power system with parallel operation of synchronous generator and hydrogen power source. Results: The tasks of structural synthesis of a combined power plant with current-based electronic inverter application, as well as justifications of power-efficient operation criteria and control algorithms of a self-contained electric power system with minimized power interchange between synchronous generator and current inverter were set and solved. Practical importance: New results are recommended to use in the design of power systems with improved technical and economic as well

Objective: To improve the integrity of running and dynamic testing results of force impact on the track, on the basis of modern facilities of data logging and wireless transmission from rotary elements of a car, as well as the change from indirect to direct methods of measurement. Methods: Comparative running and dynamic tests of the impact on the track were held simultaneously on the same section of the track, using three methods of logging vertical and side forces, that is Schlumpf (State Standard R 55050-2012), “RZhD-2016” and “NVTs-TKP” methods. The key difference of the third method was the application of strain-gauge set of wheels (TKP), making it possible to keep a continuous record of forces acting in the “wheel-rail” system throughout the track, whereas other methods allowed for the realization of the above mentioned only on districts with a limited amount of sections. Results: According to the results of comparative testing, a conclusion was made on the improvement of integrity and justification of the method of “NVTs-TKP” with an application of strain-gauge set of wheels. Practical importance: It was suggested to apply “NVTs-TKP” method to implementing organizations of running and dynamic tests when evaluating the load of an innovative rolling stock on the track.
