Smart Technologies

The development of electric power industry requires transition to the technological platform, encouraging implementation of smart grids. To set up these grids it is necessary to apply smart technologies of power supply system control modes, as well as interfaces, ensuring the connection of renewable energy sources. These interfaces may be represented by energy routers. The paper discusses the results of simulating emergency modes, caused by short circuits in 10 kV and 0.4 kV grids of non-traction users, connected via energy routers to the railway power supply system. The studies were performed in MATLAB system. Simulation results showed that the application of controlled energy routers for the non-traction user power supply completely removes electric power quality problems, allows for reliable integration of distributed generation plants into the power supply system, and limits short circuit currents and reduces the depth of the AC failure.

The Mathematical Model

This paper investigates a mathematical model of one elements of the power supply system - power transmission lines. The type of models depends on the initial simplifications, which in turn are determined by the complexity of the physics of processes. The task of improving the accuracy of modeling of emergency processes in the power system is due to the significant complexity of modern power systems and their equipment, high-speed relay protection, automation of emergency management and the introduction of higher-speed switching equipment. One of the reasons for a significant number of serious emergencies in the system is the lack of complete and reliable information for modeling modes in the design and operation of power systems. The development of a mathematical model of a three-phase power line, which provides adequate reflection of both normal and emergency processes, is relevant. The advanced mathematical model of power transmission lines allows to investigate various operational modes of electric networks. The improved mathematical model of the power transmission line reflects all the features of physical processes at state modes and transient process and provides sufficient accuracy of the results. The type of mathematical model of power transmission lines depends on the accepted simplifications, depending on the task of research. The purpose of this work is to analyze the mathematical model of the power transmission line to study the modes of operation of the power supply system, with the possibility of its application to take into account all the design features of overhead and cable power lines. The mathematical model of the power line for the study of the modes of operation of the power supply system is analyzed. It is used to take into account the design features of overhead and cable power lines, skin effect.

Continuous Working

In order to prolong continuous working time of one transmission line inspection robot, a power supply system with induction charging unit for this inspection robot is introduced in this paper. Special current transformer by which the robot could get power from power line is designed according to the magnetic field condition around the transmission line. Besides, charging circuit for Li-battery pack is also introduced. A fly-back circuit is applied in the circuit to provide precisely accessible input power for charging battery packs. Experimental results show that the power supply system could have good performance on extending the continuous working period of the transmission line inspection robot.

Continuous co-phase traction power supply system is the major change of the traction power supply. It is important to analyze the transient response characteristics of overhead contact line for the traction substation feeder protection. This article introduces the main structure of continuous co-phase traction power supply system and the control strategy of traction substation. Meanwhile, transient responses of overhead contact line in the earth short circuit are studied, including metallic earth short circuit and non-metallic earth short circuit (high resistance ground). In the PSCAD/EMTDC electromagnetic transient simulation environment, the effects on the system and the recovery process are studied which the fault occurred in the output interface of traction substation and occurred in overhead contact line.
