Nonetheless, it grows richer with each addition and change made by scientists and researchers. This entire project is based on Wireless Power Transmission systems, whose ultimate purpose is to transmit power in a uniform gain in a registered region. To accomplish this purpose, first, a schematic diagram was designed which has two parts. The first part is for transferring the power and the second part is for receiving the power. The power transferring part is modified as Antenna and the receiver part is Rectenna and both the antenna and rectenna were designed in CST software. A receiver circuit was designed for delivering the power which was designed in ADS software. The receiver circuit was constructed in three individual sections. They are antenna circuit, rectifier circuit, and buck converter. The resonance frequency of the system is 2.4GHz and after completing the analysis we get the output of (5.655 to 4.95) V DC in rectangular shaped patch antenna and (5.573 to 4.86) V DC in circular shaped patch antenna in (2 to 60) meter. In addition, we tried to figure out which antenna provides better output by differentiate the shape of the antenna. The project’s primary goal is to transmit power to a focused area and also determine the estimated cost, health concerns, and repercussions in terms of social, political, and technological factors.","PeriodicalId":438265,"journal":{"name":"2022 12th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115097787","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}

To reduce the diesel consumption, the research aims to study the performance and emission characteristics of a diesel-engine generator fueled with vaporizing ethanol via a carburetor combining with diesel on a dual fuel mode. The vaporizing ethanol is changed by increasing main jet diameter from 0.8 to 1.0 mm combined with diesel injection on the dual fuel mode, as compared with only diesel mode at a constant speed of 3,000 rpm and different loads. Results shows that the addition of vaporizing ethanol by adding main jet diameter combining with diesel led to the reduction of engine performance. The exhaust emissions, especially nitric oxide and black smoke, were reduced with vaporizing ethanol increased, but there was the increase of carbon dioxide and carbon monoxide. The research found that the use of main jet diameter at 0.8 mm in vaporizing ethanol combining with diesel resulted the addition of diesel saving to 47%, and brake thermal efficiency was dropped only by 2%. Nitric oxide and black smoke emissions were decreased up to 12%, while carbon dioxide and carbon monoxide releases were only slightly increased.","PeriodicalId":438265,"journal":{"name":"2022 12th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124210104","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 experimental results show that at Epoch=40,000, the AP(the explanation is shown in TABLE I) of the trained model is much higher for the categories with a small proportion of data than for the categories with a large proportion of data when the ratio of the data sets of anti-vibration hammer and insulator is 1:2 or 2:1, and the AP of the model trained by unbalanced data distribution is unstable compared with the AP of the model trained by the ratio of the two categories of data sets of 1:1.

When the scale of the distribution network expands, this method becomes very lengthy. In order to fill this gap, this paper proposes a Monte-Carlo-based method for identifying weak points of distribution network components. Firstly, considering the topological structure and distribution information of the distribution network, the Monte Carlo method is used to calculate the system reliability index of the distribution network. Then, through the component reliability tracking analysis, the influence factors of each component on the system reliability index are obtained, and the weak points of the system are determined by the size of the influence factors. Finally, a typical low-voltage distribution system with 10 load nodes is analyzed, and the weak components of the distribution network are found. The improvement measures to improve the reliability of the system are given. By comparing the improvement of the system reliability index before and after the weak point is modified, the validity of the weak point identification is verified.","PeriodicalId":438265,"journal":{"name":"2022 12th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126531377","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 temperature-difference experiments of three kinds of metal devices used in 110kV transmission lines were conducted for collecting their visible images with varying temperature differences in a sunlight environment. The machine learning (ML) technique was applied for modeling the relationship functions between visible image features and temperature differences. The results showed that the corresponding temperature difference of metal devices in these images could be well predicted by trained ML models. Larger illuminance of sunlight helped to obtain higher prediction accuracy. This method could be used for monitoring the abnormal temperature rise of metal parts in electrical equipment by comparing the temperatures of two different phases. It would provide a new choice for intelligent temperature monitoring in power systems, helping save costs and improve inspection efficiency.","PeriodicalId":438265,"journal":{"name":"2022 12th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116834729","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}
