The distribution and deformation characteristics play a key role in ensuring the long-term stability of tunnels. Therefore, an analysis of the distribution characteristic is of great significance. This paper takes the branch tunnel in the Yellow River Diversion Project of central Shanxi as an entity for modeling, and uses the finite difference program FLAC3D for analysis and calculation. The research results show that before the support is strengthened, the compressive stress of feet-lock bolts has exceeded the compressive strength of the bolts, with obvious stress concentration at the arch feet; the deformation mainly occurs on the vault and the bottom plate; after strengthening the support, the deformation of the steel arch prop, the axial force of the steel arch prop, and the maximum tensile stress of the anchor rods are all reduced. The stable support effect can meet the requirements of construction and later operation.","PeriodicalId":502380,"journal":{"name":"Advances in Engineering Technology Research","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139316367","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 work creates high-quality simulation software for wind power to address the complicated modeling requirements brought on by significant wind power penetration. The software implements the functions of fine modeling, offline simulation, real-time simulation, and data analysis and uses Python, Shell, and C++ language programming as its primary programming languages. Additionally, to confirm the software's functionality, this study employs OpenFAST single-unit and three-unit wind field samples. The reality demonstrates how easily real-time simulation software can be implemented and how well it does so. Software also has a cheap time and economic cost, and its application value is considerable.","PeriodicalId":502380,"journal":{"name":"Advances in Engineering Technology Research","volume":"203 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139316756","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 optimal operation model of substation is established with the objective function of minimizing the operating cost, carbon emission cost and load power variance. The optimal operation strategy of the substation is solved by the affiliation function and particle swarm algorithm, and at the same time, the starting and stopping situations of each load of the substation are solved according to integer planning. A substation in Henan Province is analyzed as an example, and the results show that the method has obvious advantages in reducing the cost of electricity consumption, carbon emission cost, and peak-to-valley difference of the power grid when considering different objectives for optimization comparison under the consideration of photovoltaic and time-sharing tariffs.","PeriodicalId":502380,"journal":{"name":"Advances in Engineering Technology Research","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139316585","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}

Based on the research and review of a large number of literatures, this paper studies the current research hotspots and main research achievements of remanufacturing evaluation, and summarizes the existing achievements from the aspects of evaluation objects, evaluation directions and evaluation methods. Through research, it is found that most of the remanufacturability currently selects economic, technical, environmental and other evaluation grades, constructs corresponding evaluation index system, assigns weight to each index, and finally obtains evaluation conclusions through hierarchical analysis and entropy method.","PeriodicalId":502380,"journal":{"name":"Advances in Engineering Technology Research","volume":"73 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139316941","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}

Finally, the system is tested in user information management, site data management and site selection process management modules. The Activiti process framework can realize the business process modeling of the system, and can effectively help the site selection personnel to carry out site selection planning. At the same time, site selection personnel can carry out online interaction, facilitate site selection personnel to conduct on-site operations to obtain real-time data, and reduce workload and information errors, and improve the speed and quality of site selection under the design of mobile Internet.
