Beketov national university of urban economy in Kharkiv popup.description2 The purpose of the work is the study of modes and processes of resource consumption, development of methods and substantiation of resource conservation reserves. The object of research is modern electromechanical complexes and systems of industry and electric transport. Research methods – theoretical research, matrix method, methods of mathematical modeling, method of thermal substitution schemes, analysis, reliability theory, optimization methods. In the paper: a matrix method for calculating short-circuit currents is proposed, which allows to automate their calculation in circuits of any complexity; the model for determining the force of the electromotive force, which develops during movement, and energy consumption is applied; for calculations of energy consumption and traction force, a function for the operating modes of the drive is introduced; a method for analyzing the thermal state of an asynchronous traction motor based on thermal substitution schemes is proposed; an option to implement automatic setting of settings is presented PID controller used in the cooling automation system of an electromechanical object with changing dynamic properties; it has been proven that the effective use of resources under modern economic conditions can be achieved through the development and practical implementation of relevant resource conservation projects and scientific-methodical and technical-technological means of their optimization; the task of optimizing the operational and constructive parameters of the tram and the track superstructure, taking into account their interaction, is considered in the zone of joint unevenness; taking into account the shortcomings of the existing elevator control system, it is proposed to supplement the design of the single-speed elevator with a voltage converter, which ensures smooth deceleration of the cabin movement and its stopping accuracy thanks to dynamic braking.
