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.","PeriodicalId":143024,"journal":{"name":"2022 International Conference on Wireless Communications, Electrical Engineering and Automation (WCEEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129100570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":143024,"journal":{"name":"2022 International Conference on Wireless Communications, Electrical Engineering and Automation (WCEEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114308614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 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.","PeriodicalId":143024,"journal":{"name":"2022 International Conference on Wireless Communications, Electrical Engineering and Automation (WCEEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114728181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":143024,"journal":{"name":"2022 International Conference on Wireless Communications, Electrical Engineering and Automation (WCEEA)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122166375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
