Increase of energy efficiency of electric traction system in operating condition of sectioning posts with electric energy storage units
The increase of energy efficiency of the electric traction system is directed to achieving the target indicators, denoted by the Energy strategy of the OS Β«RZDΒ». One of the basic problems, which must be solved, is the increase of efficiency of the regenerative braking on the railway sections. This could be achieved by receiving regeneration energy. One of the possible decisions is the disposal of the electric energy storage unit in the electric traction system on the sectioning post. For some energy parameters, the installation of storage unit on the sectioning post is more effective in comparison with its location on the traction substations. The analysis of the basic methods of the electric traction system operation when the regenerative braking is applied allows determining the required parameters and finding more effective areas for using the device. The aim of the research is to evaluate the expediency and the efficiency of applying the capacitive energy storage units on the railway posts of the DC sectioning to increase the efficiency of using the regenerative braking as well as to increase the energy efficiency of the electric traction system. Research methods: the simulation modeling of the traction capacity in the electric traction system based on the experimental date, obtained from the measuring system of the DC electric locomotive.Β Results. The authors have analyzed the influence of the capacitive energy storage units, located on the sectioning posts on the operation modes of the DC electric traction system when the regenerative braking is applied. The electric energy storage unit operation was modeled for one of the actual area of the railroad with several areas between substations, on the base of the data, obtained by the results of processing the goods train traction load. The cross-section of a road includes gradients up to 10 ppm, that causes the wide use of the regenerative braking. The authors proposed the algorithm of controlling the operating mode of the electric energy storage unit on the post of the DC sectioning, which is based on measuring voltage level on the wires of the post of the DC sectioning and on the wires of the electric energy storage unit; considered the diagram of controlling the energy storage units with the counter turning on of the election keys, which provides the energy storage charge unit when using the trains with regenerative braking and its discharge at minimal voltage in the wires of the sectioning post by the maximal traction load. It was shown, that the use of the electric energy storage units on the post of the DC sectioning allows increasing the average voltage on the wires of the adjacent traction substations, reducing electric energy losses in the traction system, the level of the traction load of the converting unit input and the total electric power consumption, determined by the connections of the contact network of the traction substations. The authors estimated the influence of the storage unit on the working parameters of the electric traction system. The paper mentions the defects of the considered diagram of the energy storage unit connection to the wires of the DC sectioning post. The defects can be removed by improving the control diagram

The aim of research is to increase the capacity of promising distribution electric networks of railways with renewable energy sources through optimal reconfiguration of electrical circuits.

Methods. Optimization problem was solved by the branch and bound method, simulation modeling of the electrical network modes was performed in Matlab Simulink. Results. The authors have developed the algorithm for reconfiguring the electrical network to increase its capacity based on solving the problems of optimizing normal modes (static reconfiguration) and minimizing power consumption without calculating steady-state modes in the pace of electricity demand change processes (dynamic reconfiguration). To ensure the admissibility of the modes of distribution electric networks, approaches to managing the supply of active (based on renewable sources) and reactive capacities and the demand of active consumers were proposed. The paper introduces the results of implementation of dynamic reconfiguration for the test circuitry without taking into account the power supply and demand management of active consumers, indicating the validity of the proposed approaches to improving the transmission capacity of the electrical network

Π΅ΠΌΡ ΡΠΏΡΠ°Π²Π»Π΅Π½ΠΈΡ.The increase of energy efficiency of the electric traction system is directed to achieving the target indicators, denoted by the Energy strategy of the OS Β«RZDΒ». One of the basic problems, which must be solved, is the increase of efficiency of the regenerative braking on the railway sections. This could be achieved by receiving regeneration energy. One of the possible decisions is the disposal of the electric energy storage unit in the electric traction system on the sectioning post. For some energy parameters, the installation of storage unit on the sectioning post is more effective in comparison with its location on the traction substations. The analysis of the basic methods of the electric traction system operation when the regenerative braking is applied allows determining the required parameters and finding more effective areas for using the device. The aim of the research is to evaluate the expediency and the efficiency of applying the capacitive energy storage units on the railway posts of the DC sectioning to increase the efficiency of using the regenerative braking as well as to increase the energy efficiency of the electric traction system. Research methods: the simulation modeling of the traction capacity in the electric traction system based on the experimental date, obtained from the measuring system of the DC electric locomotive. Results. The authors have analyzed the influence of the capacitive energy storage units, located on the sectioning posts on the operation modes of the DC electric traction system when the regenerative braking is applied. The electric energy storage unit operation was modeled for one of the actual area of the railroad with several areas between substations, on the base of the data, obtained by the results of processing the goods train traction load. The cross-section of a road includes gradients up to 10 ppm, that causes the wide use of the regenerative braking. The authors proposed the algorithm of controlling the operating mode of the electric energy storage unit on the post of the DC sectioning, which is based on measuring voltage level on the wires of the post of the DC sectioning and on the wires of the electric energy storage unit; considered the diagram of controlling the energy storage units with the counter turning on of the election keys, which provides the energy storage charge unit when using the trains with regenerative braking and its discharge at minimal voltage in the wires of the sectioning post by the maximal traction load. It was shown, that the use of the electric energy storage units on the post of the DC sectioning allows increasing the average voltage on the wires of the adjacent traction substations, reducing electric energy losses in the traction system, the level of the traction load of the converting unit input and the total electric power consumption, determined by the connections of the contact network of the traction substations. The authors estimated the influence of the storage unit on the working parameters of the electric traction system. The paper mentions the defects of the considered diagram of the energy storage unit connection to the wires of the DC sectioning post. The defects can be removed by improving the control diagram
