As a result, the fault location method based on single measurement information is no longer applicable. In this paper, we determine the approximate area of the fault location with obtaining the residual value of state estimation. Further, by analyzing the change of Clarke current phase angle difference at both ends of each section, the fault criterion in the line section is obtained, and the fault is located according to this criterion. The proposed method requires the measurement data from supervisory control and data acquisition (SCADA), power quality monitoring system (PQMS), as well as other monitoring systems to implement state estimation and requires the current measurement data to carry out Clark Transformation. Moreover, the phase-angle differences of the Clark currents of the selected sections are sent to the master server to judge which section has faulted. Finally, an example is given to demonstrate the availability and accuracy of the method with MATLAB/Simulink. The result shows that the measurement information and criterion increase is achieved more effectively by improving fault section location.","PeriodicalId":120565,"journal":{"name":"2022 International Conference on Environmental Science and Green Energy (ICESGE)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132403410","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}

It has been widely used in uranium conversion plants, uranium enrichment plants, and nuclear fuel element plants. Unlike the outdoor leakage of UF6, the isolation function of the plant and the air filtration system will effectively control the UF6 and its hydrolysates in the plant when leakage occurs. UF6will react chemically and diffuse simultaneously in the plant. For the workers in the plant, Accidents are more likely to cause injury. Based on the release path and leakage process of UF6, this paper comprehensively considers the flash, diffusion, and sedimentation processes of UF6, and a UF6leakage source term model in the confined space is finally established. The model decomposes the release process of UF6in the confined space into several nodes. The substance and energy of each component can be obtained through the steady and transient calculation of UF6and its hydrolysates in nodes. Finally, the spatial distribution of UF6 and UF6 hydrolysates in the entire confined space in different time intervals can be obtained.","PeriodicalId":120565,"journal":{"name":"2022 International Conference on Environmental Science and Green Energy (ICESGE)","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124045936","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 estimation of energy recovery potential from waste will likely motivate the development and deployment of integrated waste management systems that will address the prevailing double challenges of energy poverty and waste-associated environmental and human health impacts. Mathematical models coupled with an extensive literature review were used to estimate the anaerobic digestion, incineration and gasification-derived energy whilst the 2019 Refinement to the 2006 Intergovernmental Panel on Climate Change (IPCC) Guidelines for estimating emissions of methane from solid waste disposal sites (SWDS) was used for landfill derived energy. National mean annual energy generation potential of 129.2 GWh from anaerobic digestion, 415.8 GWh from incineration, and 168.5 GWh from gasification have been estimated for the 2016 to 2035 spatial scale whilst those for 2010 to 2050 temporal scale have been estimated at 131.8, 424.2 and 171.9 GWh for anaerobic digestion, incineration, and gasification, respectively. Considering the landfill gas to energy national annual average electrical power potentials of 43.1 and 66.8 GWh have been respectively estimated for the 2010 - 2050 and 2016 - 2035 spatial scales. The estimated energy potentials from anaerobic digestion, landfill gas to energy, incineration, and gasification contribute 1.5%, 2.5%, 5%, and 2% respectively to the national electricity consumption. The review and analysis showed that an untapped energy potential from waste generated in Zimbabwe's urban centers exists, which requires urgent strategies for its exploration.","PeriodicalId":120565,"journal":{"name":"2022 International Conference on Environmental Science and Green Energy (ICESGE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131252218","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 potential of bio-methane production by mono-digestion of blood, cow dung and paunch content as well as the co-digestion of the same substrates was carried out at a ratio of 1:1:1. The digestion process was done using a Bioprocess Automatic Methane Potential Test System (AMPTS II) system at a mesophilic temperature of 37°C. The highest bio-methane yield was recorded in the ternary mixture at 2,178 NmL and for mono-digestion paunch content produced the highest volume of gas at 992 NmL. A volatile solids reduction of 81% was reported in the digestion of paunch content, which was the highest in all reactors. Higher volatile and total solids reduction results in higher biogas yield and blood were observed to have the lowest reduction in volatile and total solids and the lowest bio-methane yield at 518 NmL. A synergic effect with the highest synergic ratio was found in the ternary mixture at 2.95 and the lowest was for a binary mixture of paunch content and cow dung at 1.48. Kinetic analysis showed that the quadratic model was the best fit for the data compared to the linear model for both the mono and co-digested substrates.","PeriodicalId":120565,"journal":{"name":"2022 International Conference on Environmental Science and Green Energy (ICESGE)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131510069","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}

According to simulation results, the flow state is the most stable under the rated operating condition. In addition, the pressure span in the guide vane, labyrinth seals, draft tube and other channels is uniform, and there is no flow shedding and blade passage vortex in the runner. Furthermore, the flow regime is relatively unstable in the other two operating conditions. The fluid flow impacts the blades, resulting in flow separation. There are many vortices in the draft tube, which may threaten the safe and stable operation of the turbine. Moreover, the pressure distribution trend in the fluid channel under the three operating conditions is almost the same. The results of this paper can provide a useful reference for the design and installation of giant Francis turbine units.","PeriodicalId":120565,"journal":{"name":"2022 International Conference on Environmental Science and Green Energy (ICESGE)","volume":"169 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127198599","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}

Particulate matter, particularly particles with an aerodynamic diameter of less than 30 μm, will get deposited in our organs through various processes. Traditional air purification technologies based on filters and fans are effective in reducing indoor air pollution. Given the effects of air pollutants on human health, there is a strong need for a technology that can work for ambient air by covering a large area of volume. Pulsed radio waves-based technology can be a strong solution for this kind of application. This Paper explains the technology and its application in detail. The technology used pulsed radio waves to create electromagnetic fields that affect the pollutants in the air to coagulate and deposit on the surface. This is how it mitigates the pollutants in the ambient environment. Testing has shown that in a controlled environment, particulate matter concentrations can be reduced by more than 65-70%. In addition, we tested in the real field and observed more than a 55% reduction in Particulate matter concentration in a month considering all external parameters, including metrological conditions.","PeriodicalId":120565,"journal":{"name":"2022 International Conference on Environmental Science and Green Energy (ICESGE)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128266593","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}
