Modular aggregation of power converters of mobile power systems

Introduction. It is possible to increase the profitability of small farms remote from the external energy system through the use of mobile energy systems using renewable energy sources in areas with high potential for wind and solar energy. In addition, such systems will increase the efficiency of emergency rescue and emergency restoration work in areas of natural disasters and destruction. The main advantages of mobile power systems, as well as the advantages of modular aggregation of the functional elements of these systems, are considered. The main stages of the synthesis of mobile energy systems based on renewable sources are revealed. Basic power electrical circuits of modular blocks of electricity converters and methods for connecting them to each other are proposed, which make it possible to increase the reliability of operation and installed capacity of a mobile power system, as well as optimize its structure depending on consumer requirements for reliability of electricity, including uninterrupted power supply, and power quality. To improve the operational and technical characteristics of a mobile power system, it is proposed to use the positive property of static converters - to pass energy flows in both directions. A block diagram of a mobile energy system based on modular blocks of static converters has been developed and the features of its operation are revealed.
The purpose of the study is to develop structural and circuit solutions for modular units of electricity converters to improve the operational and technical characteristics of mobile power systems.
Object of study: structural and circuit solutions of static electricity converters and mobile power systems.
Materials and methods. When conducting research, methods of statistical information processing, theoretical foundations of electrical engineering and power electronic converter technology were used.
Results and conclusions. Schematic electrical diagrams of modular blocks of electricity converters and methods for connecting them to each other are proposed. A block diagram of a mobile power system based on renewable energy sources and modular blocks of electricity converters has been developed. The features of the operation of modular units of electricity converters and the operation of a mobile power system are considered, which will increase the efficiency of pre-design work on the development of autonomous power plants with improved operational and technical characteristics.
