In the plateau environment, complex geographical conditions have a dramatic impact on fuel consumption. Traditional fuel consumption models can not meet the requirements of plateau prediction accuracy and robustness. In this paper, a back propagation fuel consumption prediction model based on the Cauchy Multi-Verse optimizer (CMVO) considering plateau conditions is proposed. A Cauchy factor is introduced to improve the global search ability of MVO. Moreover, a tangent descent factor is introduced to reconstruct its travel distance rate (TDR), which significantly improves the convergence speed of algorithm. The experimental results show that the convergence time of CMVO-BP is 50% shorter than that of MVO-BP; Compared with logistic regression and RNN algorithm, the prediction accuracy is improved by 5.7%. Under the plateau high-speed condition, the accuracy of fuel consumption prediction can reach 97.5%, R2 coefficient score can reach 95.7.","PeriodicalId":304779,"journal":{"name":"2022 9th International Forum on Electrical Engineering and Automation (IFEEA)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127728602","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}

The Wenchuan earthquake triggered a lot of co-seismic landslides around the power station, resulting in a significant increase in the number and scale of landslides post the earthquake. The evolution of landslides around Yingxiu Hydropower Station after the Wenchuan earthquake is studied by using the high-resolution remote sensing images from 2004 to 2020. The landslide activity post the earthquake declined gradually. The first 5 years post the earthquake is the strongest activity period. Large scale landslides and debris flows occurred in 2010 and 2013, respectively. The landslide activity decreased significantly since 2014, and only small landslide occurred from 2014 to 2020. There are still a large number of loose solid materials in the gullies and on the slopes. In the future, under the effect of heavy rainfall, there is still the possibility of large-scale debris flow disasters, and monitoring should be strengthened.","PeriodicalId":304779,"journal":{"name":"2022 9th International Forum on Electrical Engineering and Automation (IFEEA)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116418752","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}

On this basis, the natural frequencies and mode shapes of the low-voltage winding of an SFSZS-40000/110 transformer are analyzed, and the influence of the elastic modulus, the number of spacers, and the thickness of the spacers between end disks and clamping rings are discussed. The results show that windings’ natural frequencies satisfy the multiple relationship, and the axial vibration modes show winding disk vibration in the same or opposite direction. The natural frequencies increase with the increasing elastic modulus and quantity of spacers. The axial displacement of end disks increases with the increasing thickness of spacers at winding ends. The conclusion can provide an important basis for further research on the assessment of the withstand ability to short circuit of transformer windings.","PeriodicalId":304779,"journal":{"name":"2022 9th International Forum on Electrical Engineering and Automation (IFEEA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115790951","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}

The proportion of pure electric vehicles is basically maintained at about 80%. It makes broad market prospects for charging facilities. However, the operating enterprises have the problems of single business model and weak profitability[1].It limits the speed at which enterprises can recover construction costs and seize the user market. The purpose of this paper is to attract user traffic and maximize the benefits of enterprise operation. This paper analyzes the charging behavior of charging station users. According to the usage of different types of charging piles, suggestions are made for setting a reasonable free parking time. The number of typical faults of charging facilities is studied by using autoregressive integrated moving average model (ARIMA). The result provides the data basis for enterprise equipment operation and user management. We discovered that the free parking time of the fast charging pile can be set at 1.5 to 2 hours. And the free parking time of the slow charging pile can be set at 3 hours. The ARIMA model can effectively predict the number of failures. We can make the operating and maintenance plan according to the forecast results. That will improve the efficiency and profit.","PeriodicalId":304779,"journal":{"name":"2022 9th International Forum on Electrical Engineering and Automation (IFEEA)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127167950","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}

At present, in vulnerable lines assessment based on traditional electrical betweenness, there are some problems such as not setting assessment trigger condition, not comprehensively characterizing the importance of the line, and not effectively taking into account its reliability of the line. For this reason, this paper proposes a method of vulnerable line assessment based on comprehensive betweenness. In this method, the improved electrical betweenness is established and the comprehensive betweennes indicator is proposed based on it, which can realize the scientific representation of the importance and reliability of the line. At the same time, set the complex network characteristics as the trigger condition for assessment. The experimental results show that the proposed method can greatly improve the accuracy of vulnerable line assessment compared with the results based on traditional electrical betweennes while this method can greatly reduce the assessment time compared with traditional simulation. The method in this paper gives consideration to the assessment efficiency while ensuring the assessment accuracy.","PeriodicalId":304779,"journal":{"name":"2022 9th International Forum on Electrical Engineering and Automation (IFEEA)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125313677","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}
