Assuming that porous media consist of capillaries only with single cross-sectional shape doesn't concur with real situations, and most porous media in nature are tremendously complex and consist of numerous tortuous capillaries/pores with various cross-sectional shapes. This paper derives a general permeability model of porous media composed of capillaries with mixed cross-sectional shapes and compares the predicting results of permeability by the present model with those by the previous models and experiment data of previous studies. The analysis results indicate that there is an optimal cross-sectional proportion of mixed shapes for the pores/capillaries in the porous media.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114596732","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}

Therefore, a discrete bounded constrained distribution method is used to solve the problem of uncertainty of stochastic distribution in their optimal allocation. A capacity allocation model of regional integrated energy system with discrete bounded distribution is established, and the model is converted into a deterministic semi-deterministic plan by Lagrangian dual principle. The simulation results show that although the investment and operation costs increase after considering the discrete bound constraint distribution, the load shedding loss is reduced to a certain extent; while the total system cost increases with the increase of the discrete bound perturbation range, the supply and sale of energy of the system is guaranteed, which is economical and reliable.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121971895","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 finite element simulation method is used to simulate the overall heat dissipation of the press-pack IGBT unit when it is placed in the air and immersed in the PCM. Moreover, the junction temperature change of the IGBT chip is analyzed. It is concluded that compared with the chip junction temperature of the press-pack IGBT unit in the air, the chip junction temperature under PCM immersion is much lower and the chip surface temperature is more uniform, which indicates that the phase-change cooling material has a better heat dissipation effect.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116817638","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}

In view of the fact that VFTO lacks the overall identification of time-frequency domain parameters and statistical characteristic analysis. A time-domain identification method combining the singular value decomposition (SVD) and the ESPRIT is proposed. Based on the measured VFTO waveforms obtained from the 220 kV GIS experimental platform, the proposed method is used to obtain the modal parameters of each harmonic component of the VFTO, including subharmonic amplitude, frequency, decay factor and initial phase angle. Further, the mean and variance of each mode parameter with normal distribution are obtained by parameter estimation, and the correlation between subharmonic amplitude and breakdown voltage is analyzed to establish the reconstruction model of VFTO transient waveforms under different breakdown voltages. the effectiveness of the proposed method is verified by comparing the test set.","PeriodicalId":431552,"journal":{"name":"2023 6th International Conference on Energy, Electrical and Power Engineering (CEEPE)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128747691","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}
