Electric Rolling Stock

Increasing the efficiency of cargo transportation by rail is not only one of the main directions of the company JSC “Russian Railways” but also one of the main tasks of our country in order to achieve sustainable economic growth. Electric rolling stock is the largest consumer of electric energy in the company, that’s why its effective and failure-free operation is the way to solve the set tasks. The paper deals with studies related to the operation modes of a freight electric rolling stock of direct current for the purpose of determining the requirements for electric energy storage device, since it is the electric rolling stock that determines the daily schedule of electric load. The order of the analysis of experimental trips of freight electric locomotives of a direct current on the basis of cartridges of recorders of traffic parameters installed on the locomotive is determined. On the basis of the analysis of conducted trips, the main requirements for the energy storage device were obtained with a single running of electric DC rolling stock, namely the average duration of the operation modes of the electric locomotive, the maximum, minimum, and average values of voltage and current, the average value of the electric energy returned to the contact network, time of charge/discharge, and the useful energy intensity of the electric energy storage device. The studies were carried out with the support of the Russian Foundation for Basic Research for the project No 17-20-01148 ofi_m_RZD/17.

Predictive Controllers

The article discusses the power supply system of an industrial enterprise, which included a turbine generator plant operating on the basis of a synchronous generator equipped with predictive voltage and rotor speed controllers, as well as a high-power electric energy storage device. A description of the models of this plant, predictive controllers and energy storage, as well as the results of modeling when the system goes into an isolated mode of operation are given. Simulation was performed in MATLAB environment using Simulink and SimPowerSystems packages. The purpose of the work was to study the behavior of the proposed predictive controllers during the transition of the power supply system to the island (isolated) mode. Based on the results of computer simulation, it was concluded that the use of predictive controllers improves the damping properties of the system. The use of an energy storage device that is automatically connected to the network when the voltage drops, allows to reduce the overvoltage at the terminals of the generator during its unloading, as well as to reduce the required mechanical power on the turbine shaft in comparison with a permanently connected device. Predictive controllers can be recommended to increase the stability of distributed generation plants when switching to an isolated mode. It is advisable to conduct further research in the direction of creating algorithms for coordinated operation of controllers

Electric Energy Storage

A solution to the problem of increasing the efficiency of traction electric drive systems, taking into account the steady increase in electricity prices, is proposed by using storage devices. Promising types of energy storage devices are considered. A comparative analysis of the main types of batteries and supercapacitors is carried out. The description, types, and main technical characteristics of batteries and supercapacitor energy storage devices are given. The choice of the best energy storage device is justified. The technical characteristics of specific models of supercapacitors are compared and the required number of individual storage devices of different models is calculated in accordance with the supply voltage of the engine and the energy consumed by them in the acceleration mode. The supercapacitor model for forming a storage battery was selected according to the following optimality criteria: minimum mass, minimum price, and minimum number of individual capacitors.
