In order to avoid the damage of secondary impact caused by reclosing onto a permanent fault and increase the successful rate of reclosing, the application of adaptive reclosing technology for transmission lines has been relatively common, and the development of adaptive reclosing technology for distribution lines has been relatively slow. The adaptive reclosing technology of distribution network based on signal injection is studied in this paper. Compared with the fault nature identification method based on the electrical characteristics of the fault itself, the scheme of adaptive reclosing technology based on additional injection of trial signal in the primary system has the advantage of not being limited by the structure and parameter characteristics of the distribution line itself, which can fundamentally overcome the difficulties faced by the fault property identification method based on the electrical characteristics or arc characteristics of the line fault recovery stage.","PeriodicalId":240400,"journal":{"name":"2021 IEEE 4th Advanced Information Management, Communicates, Electronic and Automation Control Conference (IMCEC)","volume":"109 9-10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120890484","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}

How to reduce routing overhead and keep convergence time within an acceptable range have become an urgent issue. In this paper, we propose routing update acquisition delay based on the location of topology change. Node centrality is used to set different timers for fetching Link State Advertisement (LSA), so as to reduce large overhead caused by simultaneously broadcasting LSA Interest. Simulation shows that routing overhead reduction is more obvious when link changes rapidly. At the same time, since the delayed LSA Interest can return data directly from in-network cache, convergence time is also kept within a small range.","PeriodicalId":240400,"journal":{"name":"2021 IEEE 4th Advanced Information Management, Communicates, Electronic and Automation Control Conference (IMCEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123791106","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 this paper, MRAS method is used in the PMSM sensorless control, the position estimation of traditional MRAS sensorless method is sensitive to parameter variation during the operation of PMSM. To solve the problem, simulation has been done at first to study the parameter sensitivity of traditional MRAS. Base on the simulation results that variations in inductance and flux linkage have a greater impact on MRAS position estimation, an improved MRAS sensorless method is proposed in this paper. The MRAS adjustable model is updated by the FFRLS parameter identification results in each control cycle. The simulation results show that the improved MRAS position estimator can effectively reduce the influence of parameter variation on rotor position estimation.","PeriodicalId":240400,"journal":{"name":"2021 IEEE 4th Advanced Information Management, Communicates, Electronic and Automation Control Conference (IMCEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124046300","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 optimization scheme of MC-CHNN is as follows: we use a piecewise annealing function to improve the convergence speed of blind detection. To further reduce the complexity of the MC-CHNN algorithm and improve the sensitivity of MC-CHNN, we propose to apply a new activation function called the multi-clustering function to MC-CHNN and replace the activation function of CHNN-RIHM with multi-clustering function when dealing with discrete multilevel signals. The simulation results show that the MC-CHNN has a faster convergence speed, stronger anti-noise capability, and can be better applied to low SNR than its competitors.","PeriodicalId":240400,"journal":{"name":"2021 IEEE 4th Advanced Information Management, Communicates, Electronic and Automation Control Conference (IMCEC)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124026835","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}

Unfortunately, the inevitable errors resulted from the experimental equipment and environmental factors result in deviations in reconstructing the acoustic spectrums to affect the detection results. To overcome these errors, this paper proposes a coordinate rotation based method to correct the peak point locations. The method can address both the over-correction and under-correction issues of the existing temperature iterative correction algorithms, as well as the problem of iterative algorithm failure caused by two measured frequencies being too large or too small at the same time. The experimental results show that the method effectively reduces the error of frequency and acoustic attenuation coefficient measurement value, and optimizes the design and implementation process of gas sensor based on acoustic relaxation theory.","PeriodicalId":240400,"journal":{"name":"2021 IEEE 4th Advanced Information Management, Communicates, Electronic and Automation Control Conference (IMCEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128373587","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}
