AbstractPurpose. Development of a method for the synthesis of power supply voltage regulator for energy-saving control of asynchronous drives of long-term operation mechanisms with a slightly varying load curve and without the need for speed stabilization.Methodology. For the research, the provisions of the theory of electrical machines, methods of synthesis of automatic systems, mathematical modeling in the MatLab package and methods of statistical analysis were used. Findings. The method was developed and the voltage regulator of energy-saving control of asynchronous drive was synthesized according to its algorithm under the conditions of load oscillation due to the chaotic change of the technological task and ensuring the permissible dynamics due to the intensity setter, which is installed in series with the regulator. Recommendations are given for the sequence and circuit switching on for the automatic system in the start-up and steady-state operation modes, and also the interval of limiting the rational slip value is selected, which will ensure the highest possible energy efficiency.Originality. An original method is proposed for determining the transition function of voltage regulator for energy-saving control of an asynchronous drive with the provision of permissible dynamics in transient conditions and indirect stabilization of the speed of long-term operation mechanisms and with a low-variation load curve. The choice of the interval for limiting the rational slip value and the sequence of switching on the control circuit depending on the current mode of operation of the electric drive system is substantiated.
Practical value. The use of the proposed controller will allow the creation of the automatic asynchronous drive system, which can save you up to 47 % of power in case of significant load drop.
