Abstract
Currently, Smart Grid technologies based on energy flow management, the use of distributed generation units and semiconductor converting devices designed to improve the quality of electricity and the reliability of the work of electrical complexes are actively applied in the electric power industry. One of the technologies of Smart Grid is the creation of energy routers that can actively influence the parameters of electricity and its consumption modes. They include special transformers and controlled converters and are designed to manage energy consumption, connect distributed generation units and provide two-way energy flows. The results of a computer and experimental study of energy routers with high-frequency transformers designed for intelligent power supply systems are presented. The issues of improving the quality of electricity in networks of non-traction consumers of railways through the use of energy routers are considered. The results obtained confirm the possibility of using energy routers for power supply of railway facilities with increased requirements for the quality of electricity. On the basis of computer research, it has been shown that the use of intelligent elements in the power supply systems of non-traction consumers allows us to solve problems of improving the quality and reliability of energy supply of railway transport facilities. The use of energy routers for power supply to responsible consumers makes it possible to completely eliminate problems with the quality of electricity. The developed model of an energy router can be used to analyze the modes of power supply systems equipped with these devices. The results of experimental studies of the operation of the high-frequency transformer confirmed its compliance with the calculated parameters. The effect of using such transformers in consumer electrical complexes leads to a significant reduction in overall dimensions. The measurements showed that the high-frequency transformer fully complies with the calculated data: the voltage pulses have a pronounced rectangular character, the signal is transmitted through the magnetic circuit without distortion in shape and phase shift angle, the frequency was 12.07 kHz.
