The concept of "Smart Grid". popup.stage_title Head Nerubatskyi Volodymyr P., Кандидат технічних наук Registration Date 15-07-2019 Organization Ukrainian State University of Railway Transport popup.description2  Increasing the energy efficiency of traction power supply systems is achieved through the use of energy efficient semiconductor converters that will realize the principles of Smart Grid intelligent systems, improve the efficiency of traction power and electric traction systems and reduce the cost of electric energy. The modulation algorithms are studied and the parameters of the output voltage and output current quality are realized in autonomous voltage inverters. The methods of introduction of pulse-width modulation are considered. When conducting the analysis of the spectra of higher harmonics of input currents from autonomous voltage inverters in the implementation of various algorithms, such as single-time modulation and pulse width modulation, it is possible to implement a compensation algorithm for control of traction voltage inverters, which allows to realize mutual compensation of higher harmonics of input currents, which achieves the improvement of the coefficient incoming current pulsations. The results of modeling in the form of energy characteristics and radiation indices of higher harmonics of current and voltage to the network of load and power are obtained.
