However, in the cluster analysis of power measurement data, the privacy information of power users may also be disclosed. To defend the privacy information of power users, the article applies differential privacy technology to cluster analysis of power metering data to avoid power users’ privacy leakage. First, the article presents the attack model that exists in the cluster analysis of power metering data. Then, the article add Laplacian noise to the power metering data to defend against attacks in the cluster analysis of attackers. Next, to enhance the data availability of noise-added power measurement data in cluster analysis, the article limits noise distance based on the results of the cluster analysis. Experiments show that method proposed in article can guarantee the privacy information of power data during the cluster analysis of power metering data, and ensure the data quality of the power metering data after privacy protection.","PeriodicalId":110429,"journal":{"name":"2021 IEEE 4th International Electrical and Energy Conference (CIEEC)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121918970","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}

For the purpose of improving the intensity of ionized gas in plasma reactor and obtain high concentration of oxygen active particles, a coaxial plasma reactor with discharge gap less than 0.3 mm is designed by using quartz as the barrier dielectric. The characteristics of narrow gap strong ionization dielectric barrier discharge and its application are researched in this paper. Taking the amount of O3 produced by discharge as the evaluation index, the effects of different voltage and gas types on the discharge of plasma reactor have been studied. Furthermore, the effects of different discharge power and aerated stone on the degradation of methylene blue wastewater are discussed. The results show that the narrow gap plasma reactor can achieve stable strong ionization discharge and the discharge electric field strength is 33.5 kV/mm. The optimal discharge voltage (peak-to-peak voltage) is 14.2 kV for producing high concentration oxygen active particles by narrow gap plasma reactor. The concentration of O3 produced by ionizing air is above 500 ppm, the concentration of O3 produced by ionizing O2 is above 2300 ppm. Moreover, the optimal discharge power is 19.6 W for decolorization of methylene blue. Under aeration condition and treatment time for 3 min, the decolorization ratio of methylene blue can reach 99.48 %, its concentration is degraded from initial 50 mg/L to 0.26 mg/L. The narrow gap plasma reactor can greatly improve the discharge electric field strength and discharge performance. It is expected to provide a new idea for the development of efficient and green degradation technology of organic wastewater in industry.","PeriodicalId":110429,"journal":{"name":"2021 IEEE 4th International Electrical and Energy Conference (CIEEC)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124693304","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}

This paper aims at studying the terahertz frequency domain characteristics of high temperature vulcanized (HTV) silicone rubber (SIR) by terahertz time-domain spectroscopy (THz-TDS). Besides, the effects of high temperature on HTV SIR and the ageing mechanism in terahertz frequency domain are explored. The results show that ATH (Al(OH)3) in HTV SIR has obvious characteristic peaks at 1.2THz and 1.33THz, which can also increase the refractive index and dielectric constant of HTV SIR. Moreover, thermal ageing increases the refractive index and dielectric constant of HTV SIR in terahertz frequency domain with ageing time. The results of Fourier transform infrared spectroscopy (FTIR) show that the intensity of -OH increases but the intensity of C-H, -CH3 and Si-O-Si decrease with ageing time, which helps explain the results of THz-TDS. This study shows that THz-TDS is of great significance to the detection of polymers.","PeriodicalId":110429,"journal":{"name":"2021 IEEE 4th International Electrical and Energy Conference (CIEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129698099","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 discharge characteristics, ablation characteristics of propellant and plasma movement characteristics of APPT at different initial voltages are systematically studied. By fitting and estimating APPT circuit parameters and system performance parameters under different initial voltages, the internal mechanism of influence of initial voltage change on thruster performance is obtained. The results show that with the increase of discharge voltage, the plasma velocity increases, the impulse bit, specific impulse and efficiency of the thruster all increase, and the system performance improves. But with the increase of voltage, efficiency of the system energy converse to discharge energy decreases, while the mass of the ablated propellant increases, the proportion of the ablated propellant which is effectively ionized and accelerated by Lorentz force decreases. This is not conducive to the performance improvement of thruster, it can be concluded that simply increasing the initial voltage of thruster has certain limitations on optimizing thruster performance.","PeriodicalId":110429,"journal":{"name":"2021 IEEE 4th International Electrical and Energy Conference (CIEEC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128536895","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}

This paper mainly studies the impact of DG on the load supply capacity (LSC) of the distribution network. The Dempster-Shafer structure (DS) of DG output is established by using the fuzzy analytic hierarchy process (FAHP). The LSC of the distribution network is calculated by blind number interval sampling, and the evidence focal element form of maximum load growing percentage is generated. Based on the evidence theory and blind number theory, the objective probability information and subjective range information of distribution network power supply capacity are obtained, and the belief and plausibility cumulative probability distribution of maximum load growing percentage are synthesized. The calculation results show that, compared with the traditional probabilistic and nonprobabilistic methods, the proposed method can well describe the objective and subjective uncertainty information of DG output, and comprehensively and effectively analyze the LSC of the distribution network.","PeriodicalId":110429,"journal":{"name":"2021 IEEE 4th International Electrical and Energy Conference (CIEEC)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128619956","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}
