With the continuous acceleration of development in recent years, energy has become an important strategic reserve, and energy-saving technology and environmental protection concepts have become important research directions in development. In automatic transmission, low efficiency, high energy consumption, easy to generate electric sparks are important problems at present. This project is a wireless direct drive circulation transport device, which uses non-contact power transmission to supply power to the mover in real time. The dynamic coil structure, contact (sliding touch) power supply, easy to produce electric sparks and powder and other defects, and the dynamic magnetic structure needs to lay a large number of drive controllers and position sensors for stator segmental switching power supply control along the way, resulting in complex control systems and high cost defects.

“…In the practical application of ICPT technology, power transmission methods mainly include static power supply and dynamic power supply. The dynamic power supply can be used for traction power supply for rail transit [28] and the dynamic charging for new energy vehicles [4] and other occasions. Traction power for rail transit, that is, the non-contact traction power supply system based on mobile ICPT technology can well solve many problems caused by all the wire connections in the traditional traction power supply system.…”

The traction power supply system based on Inductively Coupled Power Transfer (ICPT) technology is one of the new traction power supply technologies that will be developed in the future. As the core part of rail transit energy transfer and conversion, the traction power supply system is not only the critical system for the safe operation of rail transit, but also the main source of its failures, so it is of great significance to study its reliability. In this paper, the reliability analysis of the non-contact traction power supply system based on mobile ICPT technology is carried out using the method of (Fault Tree Analysis) FTA combined with triangular fuzzy theory and grey relational theory. Firstly, the fault tree of the system is established, and the minimum cut sets and structure function of the fault tree are obtained. Then the triangular fuzzy numbers are introduced to represent the probability of the bottom events, and the fuzzy probability of the top event and the fuzzy importance of the bottom events are determined, after that, the maximum probability of failure of the top event is obtained. Finally, the grey relational degrees of each minimum cut set are obtained and ranked. Furthermore, in order to prove the correctness of this method, the trapezoidal fuzzy FTA is introduced and compared with it. Both research results show that the loosely coupled transformer and Insulated Gate Bipolar Transistor (IGBT) module are the weak links of the system. The results obtained are consistent and realistic, which proves the correctness of the method selected in this article.

“…Besides, a control strategy with feedforward control is introduced into the energy storage system to suppress bus voltage fluctuations. By introducing a nonlinear interference observer (NDO), the shortcomings of traditional feedforward control methods that require remote measurement are solved [8]. In the recovery scheme, the energy storage device is used to realize energy storage and dispatching, and peak and valley reduction can be realized, which is a feasible scheme [9][10][11][12][13][14].…”

For high-speed rail with high energy consumption, the recovery and utilization of regenerative braking energy is essential to improve the energy consumption of high-speed rail. As a technical link, the energy bidirectional feed inductively coupled power transfer (ICPT) system can realize the regenerative braking energy recovery of the contactless traction power supply system. Furthermore, considering that the braking energy of the high-speed rail is the largest when entering the station during the whole line operation, the braking section of the station is mainly considered. This paper proposes a preset control method for segmented power supply of the energy bidirectional feed ICPT system considering regenerative braking energy recovery. By establishing the steady-state mathematical model of the bidirectional ICPT system, the influence of the internal phase-shift angles φ1 and φ2 and the external phase-shift angle γ on the operating state of the system is analyzed. To realize system synchronization under the operation of EMUs, a train braking model is established through force analysis, and a power preset controller is designed to realize the synchronous control of the power flow of the bilateral system. According to the braking process of the train entering the station, the switching control method of the segment coil under the different conditions of the single train entering the station and the multitrain entering the station is proposed to ensure the reliability and flexibility of the train power supply. The simulation results of the 350 kW ICPT system simulation model show that the system can operate stably when the power transmission simulation is switched, and the transmission efficiency can reach 89%, which proves the feasibility of the control method. Energy-saving estimates show that a single train can recover about 200–300 kWh of electric energy during single braking. The comparison with the measured data verifies the accuracy of the modeling in this paper.
