“…Это привело к созданию Российским морским регистром судоходства требований к судовым источникам питания по параметрам качества вырабатываемой электрической энергии. К данной проблеме неоднократно обращались в своих работах ведущие специалисты в области судовой электроэнергетики: Г. Е. Кувшинов, А. П. Баранов и С. Е. Кузнецов [1]- [3]. При дальнейшем развитии альтернативных источников энергии, в частности интеграции их в судовые электроэнергетические системы, внедрение интегральных стабилизаторов в судовые сети позволит решить проблему качества судовой электроэнергии, улучшив ее параметры как минимум до параметров береговых сетей.…”

The problem of the quality of ship electrical energy is raised in the paper. The main reasons for the low quality of electric energy compared to the quality of power supply for onshore power systems are described. Along with the main problem of quality, the issue of possible integration of alternative sources of electric energy in the future is considered. To maintain the necessary parameters of the quality of electricity generated by the alternative energy sources, such as capacitive (ionistors. supercapacitors), it is proposed to apply integrated stabilizer schemes. A schematic diagram of a booster stabilizer based on flint keys is proposed and considered. The principle of output voltage stabilization using semiconductor switches (a bipolar transistor, a field-effect transistor, and a bipolar transistor with an isolated gate) is described. A schematic diagram of the operation of a booster voltage stabilizer from a capacitive source of electrical energy is proposed on the example of an ionistor. Based on the basic laws of electrical engineering, a mathematical model of an electric power source and a voltage stabilizer based on which the variables on which the level of voltage stabilization depends are determined has been developed. Based on the mathematical model of the stabilizer and the capacitive source, a simulation model is developed and studied in the MATLAB computer simulation environment. A positive effect is revealed in the application of the basic electrical circuit of an integrated voltage stabilizer from a capacitive source. To verify the conducted model studies based on the proposed circuit diagram, mock-up tests are performed. The results of computer simulation are compared with the results of the output parameters of mock-up tests, and the feasibility of using the proposed circuit solutions is proved. Based on the research conducted on a computer and a real model, a number of main conclusions are made.
