During the operation of electrified railway, electric locomotive will inject harmonics into the power grid and degrade the power quality. For the weak current network system powered by long-distance transmission lines, due to the harmonic amplification characteristics of long-distance transmission lines, the injected harmonics at the line traction station side may be within the national standard limit due to harmonic amplification, but the output harmonics at the line grid side exceed the standard. Therefore, the harmonic amplification mechanism of long transmission line is studied, and the existing harmonic national standard limit is corrected, so that under the condition of harmonic amplification, each harmonic inj ected into the power grid by the traction power supply system still meets the requirements of the existing national standard. Simulation and practical engineering cases show that after the corrected harmonic limit is used to restrict the harmonic current injected into the public line by the electric locomotive, the output harmonic current at the power grid side of the public line is still within the allowable range of the existing national standard.

As a new type of clean energy, wave energy occupies an important position in the development of marine energy in recent years. And as an important tool for wave energy development, wave power generation devices have attracted the attention of various countries. Through the statistical analysis of the global wave energy distribution, it can be seen that the coastal wave energy reserves in European and China are extremely rich, which has promoted the rapid development of wave energy power generation devices. This article expounds the basic principles of wave power generation, and compares the advantages and disadvantages of all kinds wave generation devices, which shows that the current wave power generation devices mainly have defects such as low structural strength, poor system reliability, low power generation efficiency and poor material corrosion resistance. In order to meet the needs of high reliability, high power generation efficiency and low development cost of wave power generation devices, it is necessary to break through key technologies such as material strength, corrosion resistance and power generation efficiency in the future, so as to obtain new wave power generation devices with excellent performance.

This study developed an intelligent control system integrating intelligent infrared fence and multifunctional mobile power supply at the electrical test site and analyzed the design principle and functions of the device. The control system developed multifunctional mobile power supply to provide high-quality AC and DC power supply. In view of the weak prevention and control ability of the traditional security fence in high-voltage test, an active infrared intrusion detector is added to the original fence. When outsiders touch the infrared ray, the alarm device will be triggered and the power supply will be cut off remotely. The intelligent infrared fence includes infrared detection, signal detection and processing technology, with good security. The circuit design of each module in the mobile power supply system is emphatically analyzed and the multifunctional mobile power supply provides stable and high-quality input power for high-voltage test. The control system has intelligent safety management and control for sudden violations on site and inputs stable and high-quality power to instruments to achieve the goal of “flexibility, convenience, stability, precision, safety and intelligence” on the test site.

At present, the periodic preventive maintenance strategy is widely used to carry out periodic maintenance of electrical equipment. However, due to the aging characteristics of electrical equipment, the failure rate of equipment inevitably increases with the increase of service life, which directly affects the steady state availability of equipment. Based on the analysis of the maintenance cost of electrical equipment, a mathematical maintenance model for minimizing the cost rate per unit time in the whole maintenance cycle of electrical equipment is established by introducing the age reduction factor. Furthermore, the optimized strategy considers the failure rate threshold based on availability in actual operation, which well coordinates the reliability and economic costs of equipment operation. Finally, taking a circuit breaker whose life obeys Weibull distribution as an example, the simulation results verify the superiority of the proposed strategy, which can provide a powerful scientific decision for the planned maintenance of equipment.

The geological structure of Dagang Oilfield is complex. Most of the oil wells in the block have long production intervals, many production intervals, high reservoir variation coefficient and serious interlayer interference, which affect the oil production. Separate production and mixed production is an effective lifting method to solve this problem. However, due to the geological conditions of the complex fault block reservoir in Dagang Oilfield, the influence of each layer of stratified water injection well on each layer of production oil well is still unclear. In order to determine the influence of each layer of water injection well on each layer of production oil well, find out the oil-water movement law between water injection well and each layer of oil well, the timely testing technology of slicing and simultaneous production is studied, The wireless transmission mode of intermittent power supply and downhole storage is adopted to meet the requirements of timely measurement of stratification pressure by the fixed string of 3800m and 120°C, so as to make clear the production performance of oil wells in separate layers, master the oil-water movement law of formation, and effectively guide the layered production and development of oilfield.

Atmospheric pressure plasma jet technology has very promising application prospects and is widely used in medical, wastewater treatment, surface modification, and other fields. In this paper, a needle-ring discharge structure is used to generate argon plasma jets under an atmospheric pressure environment. The effects of the variation of parameters such as needle-ring electrode gap, quartz tube diameter, and gas flow rate on the starting discharge voltage and plasma jet length of the system are studied by quantitative and comparative analyses. The results show that increasing the voltage between the two electrodes will increase the jet length, but up to a certain level, the jet length will not be increased. As the argon flow rate gradually increases, the required starting discharge voltage and jet length will also increase. However, when the gas volume flow rate increases to a certain level, the generated plasma jet will deviate from the central axis of the quartz tube. The above results are interpreted qualitatively and are considered to be of great importance for the application of atmospheric pressure plasma jets.

The accurate estimation of harmonic impedance is a prerequisite for harmonic management and a reasonable division of harmonic responsibility. Existing harmonic impedance estimation methods require that the background harmonic fluctuations are small and that the harmonic currents on the customer side and the utility side are independent of each other. However, the lots of new energy sources connected to the grid, these conditions may not always hold in modern power gird. Therefore, this paper proposes a method for estimating harmonic impedance based on a filtering method of distance correlation coefficients. The proposed method screening out independent data sets of customer-side harmonic currents and utility-side harmonic currents, both sides harmonic currents can be estimated by complex independent component analysis (ICA). Compared with the existing methods, the proposed method is more accurate in estimating impedance and is more widely applicable. The validity of the method is tested through simulation experiments and analysis of measured data.

With the development of strong smart grid in China, the modular construction of smart substation has become a trend, and the smart modular substation with GIS (gas insulated switchgear) as the core has become the mainstream direction. Using digital twin technology, this study establishes a set of GIS intelligent substation health assessment and fault diagnosis model based on digital twin. The model can display the values of various instruments in the physical substation synchronously, can carry out health assessment and fault diagnosis of the equipment based on real-time data and historical data, and display the results in the model in three dimensions, with accurate indication of fault types and locations. This model can reduce the workload of on-site inspection by operation and maintenance personnel, give early warning to the possible equipment faults in advance, and provide reference and instructions for maintenance personnel to enter the site to eliminate defects.
