Abstract

The object of this research is traction electric drive systems of mobile electrotechnical systems based on various types of motors. As a result of the system analysis of the object of research, it is established that it is possible to solve the problem of increasing the energy potential of an electromechanical system only in a complex manner. It is revealed that it is necessary to consider the established mode of operation of the entire system as a whole, taking into account the conditions for the rational operation of its individual components, provided that the interconnection between them is taken into account. It is shown that a practical situation is quite frequent where the rational operating mode of individual elements of an electromechanical system and optimal control of them does not lead to the operation of the entire system on the economic characteristics. This, as a consequence, increases the consumption level of diesel fuel. Conversely, the artificial compulsion of diesel operation on the economic characteristics leads to the operation of these electrical elements of the whole electromechanical system with significant power losses. To achieve the tasks of controlling the electromechanical system, the potential method is used. According to it, it is shown that the potential of not every individual element of the electric drive is important, but the potential of their aggregate in the interaction. With a successful combination of interaction and operating modes of each element and the whole structure in general, the total energy saving potential of the whole is greater than the sum of the energy saving potentials of individual elements of the electric drive. As a result, a synergy effect is obtained. It is also shown that the task of the control algorithm is to optimize the interaction of resources to obtain a positive synergy effect, the effect of reducing the level of losses in the system. As research result, a method of increasing energy efficiency for static and dynamic characteristics is proposed. The advantages of this method are the use of the synergetic properties of the system, the integrated provision of an energy-efficient operating mode. This leads to the achievement of the most rational specific level of fuel consumption and efficiency maximization of the electromechanical system.
