Brief description, advantages, further prospects for application. A mathematical model of the signal conversion process is obtained, which is a formalized record of the argument conversion procedure in the arithmetic units of control systems, presented in the form of a graph-analytical one. The working areas of the DC voltage converter with series resonant inverters are determined. The principles of mathematical description of the elements of the state of emergency as part of the SEES have been developed; Analytical models of the elements of the graphical interface of the automated workstation (AWP) of the SEPS operator have been obtained. The phase diagrams of the RP with a switching frequency above and below the resonant one are constructed. A structural model of the excitation system of a ship synchronous generator has been developed, which ensures high quality of electricity in the dynamic modes of operation of the SEPS and stabilization of its reactive power by the following adjustment of the excitation voltage. The static characteristics of the RP with a switching frequency above and below the resonant one for all cases of energy exchange are obtained. A mathematical model of an adjustable filter-compensating device has been developed. The structural-functional model of a microprocessor system has been optimized for studying the processes of frequency control of an asynchronous motor. A mathematical model of the active resonant circuit of the RP has been created. All possible PFCs of the equivalent EMF of the input source and loading of the RP with width-frequency regulation have been obtained. Developed taking into account the requirements of EMC microprocessor automation SEES based on the developed control algorithms have advantages over existing domestic and foreign analogues, in the developed microprocessor system for stabilizing reactive power, an algorithm for tracking adjustment of the excitation current of a synchronous generator is implemented. This ensures high accuracy of reactive power distribution between generators operating in parallel (unevenness does not exceed 1.8%).
