Influences of these grounding methods on the characteristics of single-phase short circuit fault are discussed in this paper on the example of substation “Bugojno”. Modeling and simulation are implemented in EMTP-RV (Electromagnetic Transient Program-Restructured Version) software. Data recorded by protection system during normal operation and three-phase short circuit fault in the substation are analyzed and used for comparison with simulation results to validate developed model of the observed part of power system. This validated model was then used to analyze the effects of neutral point grounding methods on the characteristics of single-phase short circuit fault.","PeriodicalId":6839,"journal":{"name":"2022 21st International Symposium INFOTEH-JAHORINA (INFOTEH)","volume":"79 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85402322","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 challenges that have arisen as a side effect, such as the vast quality of data that needs to be transmitted and processed safely in real-time, require a new computing approach. One of the paradigms being used to conquer this problem is Edge computing which, due to an increase in the performance and enhancement of storage capacities, moves data processing closer to the data origin. This new approach is being applied to Programmable Logic Controllers (PLCs), the core of industrial automation since the 1960s. This paper offers a parallel comparison of state-of-the-art PLCs that are adopting Edge computing principles and their fit in an already complex industrial network.","PeriodicalId":6839,"journal":{"name":"2022 21st International Symposium INFOTEH-JAHORINA (INFOTEH)","volume":"102 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2022-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75707574","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}

Proportional and integral controller is simple, yet with clear physical interpretation. This controller, even when optimally tuned, due to fixed values of parameters might lead to a poor performance of the overall system. One way to resolve this problem is to use gradient descent optimisation of controller parameters, with simple update rules for a real time operation, and with intuitive graphical interpretation. However, gradient descent algorithms have slow convergence and decreased performance when operate in nonstationary and/or nonlinear environment. Learning rate normalisation gives time varying learning rate and minimised a posterior output error. Due to these facts, normalised gradient descent proportional and integral controller for digitally controlled speed servomechanism is presented in this paper. The recommended values of the algorithm parameters, based on convergence analysis, are proposed. Results of the experiments support the analysis.","PeriodicalId":6839,"journal":{"name":"2022 21st International Symposium INFOTEH-JAHORINA (INFOTEH)","volume":"50 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90241131","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 causes of overvoltages are different, but lightning is considered as one of the most serious causes of overvoltages. High voltage substations are one of the main parts of the power system whose faults caused by overvoltages can lead to outage of large part of power system. Therefore, overvoltage protection of a high voltage substation is very important. In order to protect the substation as much as possible from the effects of the overvoltages, it is necessary to implement elements that can help reduce these effects, for example surge arresters. This paper presents the effects of the use of surge arresters in high voltage, gas SF6 insulated substation, modeled in the EMTP-RV (Electromagnetic Transient Program-Restructured Version) software. An accurate representation of lightning surge incoming in the substation is very important because it strongly affects the design of overvoltage protection system. In this paper parameters of lightning strikes are determined using Sigma Slp software.","PeriodicalId":6839,"journal":{"name":"2022 21st International Symposium INFOTEH-JAHORINA (INFOTEH)","volume":"39 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79258999","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 approach proposed by the authors is based on the use of two-dimensional non-stationary heat conduction equations. A permanent heat source is added to these equations, because heating occurs due to eddy currents. The mathematical model proposed by the authors considers: the geometric parameters of the waveguides, the physical parameters of materials, the initial and boundary conditions, as well as the uneven distribution of the eddy current density in the waveguide. This approach allows you to simulate the brazing process for almost any materials with different geometric parameters used in the aerospace industry. In this work, we simulate the process of induction brazing of pipelines from Alloy 321 stainless steel (UNS S32100). The need to develop a module of the software system is due to: (1) high temperature of the board and the need to withstand the regime; (2) use of duct boxes to create a protective environment; (3) high material costs when developing a new technological process (for example, when brazing a larger pipe). As a result of this work, a software system module was developed and modeling of induction brazing of pipelines in protective environments from Alloy 321 stainless steel was carried out, the results of which are presented in the article.","PeriodicalId":6839,"journal":{"name":"2022 21st International Symposium INFOTEH-JAHORINA (INFOTEH)","volume":"39 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2022-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77669737","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}
