Abstract:

<p>With the increasing investment in railway construction, China’s railway transport network is now very sound, the number of operating miles is growing, and the operating speed has also made a qualitative leap. At the same time, the safety and reliability of the operation of railway signal cables and other electrical equipment has also put forward higher requirements. At the present stage, the management of railway electrical services equipment mainly relies on manual management, which is cumbersome, inefficient and unsuitable for multi-user sharing. At the same time, the structure of railway electrical equipment is complex, and the components of the equipment are prone to aging, which can easily cause equipment failure. How to professionally manage electrical service equipment and improve the safety and reliability of electrical service equipment has become an urgent problem for railway electrical service departments. Geographic Information System (GIS) architecture uses spatial data layering technology to achieve multi-level and proportional display of equipment and facilities, which can provide visual display of professional facilities such as railway engineering, electricity and power supply, and carry out multi-source and multi-temporal intelligent analysis of data, provide geographical information service interface for various professions of engineering and electricity to meet their own functional requirements. Knowledge mapping is a key technology for acquiring knowledge and building a knowledge database in the era of big data. In order to explore the hidden information between railway electrical resources, integrate seemingly independent data into the knowledge base and apply them. In this paper, we design a GIS-based electric service resource management system in combination with knowledge mapping that can make data complete and well-structured after processing scattered and redundant information, and analyze and discuss the system’s architecture, functional requirements, key technologies and development prospects.</p> <p> </p>

Abstract:

To eliminate the negative effects caused by three-phase unbalanced distribution, a novel soft-switching system based on single-phase inverter is proposed. The system achieves three-phase equilibrium distribution by adjusting the power supply of the electric equipments. This paper presents a track strategy named regulating frequency to promise no impulse current, which means regulating the output frequency of the inverter to make the output voltage of the inverter synchronize with the grid voltage. Firstly, make the output voltage of the inverter synchronize with the voltage of original access phase, then switch the electric equipment to the inverter. Secondly, make the output voltage of the inverter synchronize with the voltage of alternative access phase, then switch the electric equipment to the alternative access phase to accomplish the soft-switching. MATLAB software and experiment are used to carry out verification for this system. The result shows that the impulse current is practically zero when the electric equipments are switching. The system achieves soft-switching.

Abstract:

The pace of consumption of the building up bars is one of the significant boundaries expected to gauge the lingering administration life of a built up concrete (RCC) span deck. In the current review, first, the straight polarization obstruction procedure was utilized to gauge the erosion paces of plain gentle steel and cold wound twisted (CTD) bar examples, which were regularly utilized in the more established existing extensions. To consider the changeability of a consumption rate, the recurrence conveyances of the erosion rates for the two sorts of not entirely settled. Then, a probabilistic methodology was embraced for evaluating a current RC support and-section street span deck, exposed to consumption of bars inferable from air-borne chlorides. A computational model was created utilizing the Monte Carlo reenactment strategy, to survey the decrease in the flexural limit of a common brace. It was seen that the decrease in the mean limit and the scattering of the limit as for time, were high with the deliberate factual boundaries of the erosion pace of CTD bars. The half cell testing technique utilizes this cycle to identify whether the building up steel is under dynamic consumption. This technique uses a multimeter to quantify the expected contrast between the steel and half cell device. The examination of the expected contrast between the steel and a half cell device. The investigation of the potential distinction can show on the off chance that dynamic erosion is occurring on the building up steel. Keywords: NDT, Coastal environment, Half-cell potential Test, Chloride content, Corrosion.

Abstract:

Purpose. To develop the method for increasing the efficiency of the equipment’s maintenance and repair system, ensuring necessary level of operational reliability of the equipment, safety and reliability of the electric equipment with minimal expenses on operation. Relevance. Aging of the power equipment in railway power supply systems sharply raised a need for assessment of its states and degree of risk for operation outside rated service life. In critical conditions of technological processes and operational modes of the railways it is necessary to increase the equipment’s operational reliability. The scheduled maintenance and repair system whose main technical and economic criterion is the minimum of equipment’s downtimes on the basis of a rigid regulation of repair cycles, in the conditions of market regulations in the field of repair in many cases does not provide the optimal decisions due to insufficient financing. The solution of this problem is possible by improvement of the maintenance and repair system. Under these conditions the main direction for supporting the operational reliability of power electric equipment on TS is a development of the modern methods based on individual supervision over real changes of technical condition of power equipment. Scientific novelty. In this article the authors proposed an integrated approach, on the basis of which can be developed the effective maintenance and repair system for traction power supply systems. Proposed approach allowed to react quickly to changes of service conditions on traction substations, to control the technical condition of power electric equipment under the conditions of uncertainty, to establish interrelation between quality of service and operational reliability of the equipment, to choose a service strategy on traction substations. Practical importance. The validity of the developed method was confirmed by the results of calculations and practically by choosing the optimal maintenance's option for transformer TDTN-25000/150-70 U1 (ТДТН-25000/150-70 У1) on traction power supply substation.

Abstract:

Plastic working technologies are frequently applied nowadays, as parts can be produced with larger productivity and smaller material loss compared to other technologies, at the same time the mechanical properties of parts are more favorable. Usually large tensile, pressure, bending or torsional forces, torques are required during plastic working. While pneumatic, hydraulic or electric energy is required to generate these. Used energy is determined by the losses of the energy required for working and that of energy conversion. The losses of working equipment are determined by mechanical losses and the losses of the energy converters applied, as well as by the manufacturing algorithm operating the working equipment. The advantage of electric driven working equipment over pneumatic and hydraulic driven ones is the better efficiency of energy converters, as well as the lower price of electric power. The disadvantage of electric converters is the large dimensions compared to hydraulic or pneumatic systems. Due to the development of electric servo drives the pneumatic and hydraulic drives are to be changed to electric drives in working equipment improving their control and accuracy features besides efficiency. In this paper the loss decreasing possibility of the working equipment with electric servo is investigated.

Abstract:

With the implementation of China’s carbon peaking and carbon neutrality goals, the power industry as a key industry urgently needs to carry out comprehensive carbon accounting work. Carbon accounting of electric power equipment is an important part of carbon accounting in electric power industry. In the process of carbon accounting for electric power equipment, different carbon emission factors may lead to different final accounting results. Based on this, this paper calculates the carbon emission factors of two main raw materials required for the production of electric power equipment in different regions and different years, and applies them to the carbon footprint calculation of SFPZ-240,000/330 transformer. According to the above results, the influence of carbon emission factor selection on carbon accounting of electric power equipment is analyzed.
