Published: April 2020

Abstract
When electric vehicles are loaded with wireless charging coils, engineering targets such as efficiency and power have always been the most significant targets for designers. In the previous research work, researchers designed and optimized the above relevant targets from the aspects of coil structure and magnetic core. However, the majority of these design and optimization schemes adopt a single-size coil to verification work, and the size often don’t take the actual application environment into consideration, so it don’t have engineering guidance significance and practical application value. In order to solve the gap and cooperate better with the application in engineering, this paper carries out a complete coil design method from the perspective of engineering design purposes and application environment. Firstly, the coil design conditions are constrained from the aspects of electric vehicle loading environment and design purpose, then the circuit and coil structure are analysed and selected, all the losses that may exist in reality are calculated, and the calculation method of the maximum winding length and minimum mutual inductance requirement of the coil is introduced. Finally, the maximum winding length index of the coil winding corresponding to the design purpose and application environment is formed, and the minimum mutual inductance design requirement is formed too. The design method of this paper is complete, and it can form different design schemes for different engineering design purposes (such as different power and efficiency). It has strong guidance to practical engineering and has high practical application value.

Published: April 2020

Abstract
With the mass production and application of wireless charging system for electric vehicles (EV), and in the process of production and use of the device, it is inevitable that there will be offsets between the actual parameter and the theoretical parameter. This will lead to the deviation of the intrinsic frequency from the design value. Finally, the transmission performance decreases and the actual design requirements are not met. Therefore, based on SS resonance compensation topology and the key parameters in SAE standard, this paper analyzes the self-inductance allowable values at different power levels and frequency points. In addition, the range of allowable operating frequency bands under the inductance offset is derived, which plays a certain guiding role in the production of key devices and practical engineering applications.

Authors: Li Hui , He Jing , Cheng Fuqiang 
Published: April 2020

Abstract
Satellite power system is an important system of satellites and it has a significant impact on safe and reliable operations of satellites. Researches on anomaly detection method of satellite power systems can improve the reliability of normal satellite operations. Fixed top and bottom limitations for telemetry parameters are often used in engineering to detect anomalies of telemetry parameters, but the detection thresholds do not change with time and can neither reflect the dynamic tendency of telemetry parameters nor anomalies that occur during dynamic changes of telemetry parameters. In order to solve this problem, this paper puts forward a dynamic detection method for finding anomalous satellite power supply telemetry parameters by comparing predicted values and real-time telemetry data by using dynamic characteristics of satellite power supply telemetry parameters and the Bayesian Model. This method can be used to verify telemetry data of voltage parameters of the storage battery of satellite actually in orbit. The results show that this method can effectively detect anomalies of satellite power supply.

Published: April 2020

Abstract
The continuous growth of power demand poses new challenge to the efficiency of power system. Therefore, distributed generation (DG) is widely concerned because it can provide clean, reliable and economic power. However, the location and sizing of DG connected to the grid shall be properly selected. In this paper, the voltage stability index and the line loss reduction rate are considered synthetically, and the two indexes are transformed into a single index (VSLR) to determine the optimal location of DG. According to this index, the node with high sensitivity and high average power loss reduction rate are selected as the optimum location of DG connected to the power grid, and the optimal access capacity of DG is determined by the algorithm proposed in this paper. The simulation experiments of IEEE30-bus are carried out with MATLAB\ Matpower toolbox, and the results are compared with the existing research results. The results show that the method of studying the optimal location and sizing of DG in this paper emerges better performance.

Authors: Piao Changhao , Liu Zhiqian , Zhao Chenxu , Song Wei , Long Hongyu 
Published: April 2020

Abstract
Due to high power load peaks and long durations in extreme weather conditions, as well as large-scale unscheduled electric vehicles charging, it may cause “peak plus peak” loading in local areas of the power grid, moreover, lead to transformer substations overload operation in local areas, which is not good for distribution safe and stable operation of the power grid. Considering the driver’s willingness, this study proposes an orderly charging strategy based on the temperature control of electric vehicle on-board air conditioner. The proposed strategy first constructs the temperature control model for electric vehicle cabins with considering the temperature of entire electric vehicle and the special characteristics of urban roads. Then, multi-objective function is formed with minimum user charging cost and variance of grid load fluctuations. Finally, electric vehicles orderly charging period is optimized by combining with electric vehicle travel chains, charge constraints, time-of-use electricity prices, and substation capacity constraints. The results show that temperature-controlled dispatching can effectively reduce the electric vehicles disorderly charging load. It can serve the power grid “cut peaks and fill valleys” and smooth the overall grid load curve using an improved Lagrange relaxation algorithm to optimize electric vehicles charging period.

Published: April 2020

Abstract
Firstly, the basic principle and characteristics of GIS vibration are analyzed and studied. It is pointed out that electromagnetic force and magnetostriction are two basic forms of GIS vibration, and both of them take 100Hz as the characteristic frequency. Then through the experiment, it is found that the frequency doubling characteristics of 200Hz and 300Hz can be excited by the loose mechanical fault. These conclusions provide an important basis for the field vibration test of GIS. Finally, a successful case of vibration test and analysis is described in detail, and the basic methods of measuring point arrangement and spectrum analysis are introduced.

Authors: Qian Qiudong , Wang Qingtao , Wang Chongxu 
Published: April 2020

Abstract
When using the finite element software ANSYS to numerically simulate the thermal effect of laser irradiation, the calculation results will show some differences with the different ways of meshing. The thermal effect of finite element model under different meshing modes when loaded in the form of heat flux is studied, which is based on the process of laser irradiation of metal circular plates. The effects of element size ratio and mesh density on the simulation result are analysed. By comparing the theoretical analytical solutions with the calculation results under different element size ratio conditions, the overall scheme of meshing is determined first, and then the influence of mesh density is further explored. The calculation results show that when the element size ratio is 1 and the overall element size is 0.25mm, the finite element simulation solution gets high precision, which is consistent with the actual.

Abstract
The on-site verification of electric energy meters has become an indispensable part of power system equipment maintenance. Recently, under the call of the State Grid Corporation of China to further optimize the business environment, in order to reduce the time of power outages for customers, the “non-interruption meter replacement” business is also actively promoted. A special wiring board is installed in the single-phase energy measurement box to ensure replacement. The meter does not lose power, but this measure has greatly affected the on-site verification of the energy meter. This article is based on the new environment of “uninterrupted power meter replacement”, in-depth demonstration of the necessity, feasibility, and ease of development of a dedicated plug-in meter for the on-site verification of electric energy meters. Based on the premise of modularization, a special plug-in strip for the on-site verification of electric energy meters has been developed to ensure that the on-site verification of the electric energy meters is not affected.
