The efficiency is evaluated by comparing the specific heat rate for power generation in the reporting period with a similar indicator in the reference period reduced to the reporting period by key influencing parameters. A specific feature of the analyzed method is the reliable consideration of external influencing factors for obtaining the efficiency evaluation under compatible conditions. In particular, such external factors include the characteristics of steam, feed water, heat rate for turbine heat extraction and cleaning mode of the turbine condenser. The impact of the condenser cleaning mode on the efficiency of the turbine operating mode is considered based on the data clustering. The Affinity Propagation method has been selected for data clustering, as its special feature is working with the variable sizes and form of clusters. The efficiency evaluation with a crew-by-crew breakdown of the results allows introducing a competitive feature between the crews (operating personnel), which, in turn, will benefit from the improved efficiency of the operating modes of steam turbines. An example of evaluation based on statistical operating data for power plant turbine showing the leader among the crews according to the considered performance indicator is given. The considered method is implemented in the automated power plant energy efficiency management system, which is overviewed in the article.","PeriodicalId":285590,"journal":{"name":"2020 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133772103","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 the electric current is modeled by a boundary value problem for the Laplace equation in a parallelepiped. The zero normal derivative is assigned on the boundary except for the areas under the contacts, where the derivative is a nonzero constant. Physically, this condition corresponds to the presence of a low-conductivity film on the surface of the contacts. The problem is solved by separation of variables, and then the electrical resistance is found as a functional of the solution in the form of the sum of a double series. Our main aim is to study the dependence of the resistance on a small parameter characterizing the size of the contacts. The leading term of the asymptotics that expresses this dependence is the contact resistance. The mathematical problem is to treat the singular dependence of the sum of the series corresponding to the resistance on the small parameter: the series diverges as the small parameter vanishes. The authors solve this problem by replacing the series with a two-dimensional integral. The authors find the leading term of the asymptotics and estimate the remainder. It turns out that the main contribution to the remainder is made by the difference between the two-dimensional integral and the double sum.","PeriodicalId":285590,"journal":{"name":"2020 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114524168","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}

Its disadvantages and the methods for their elimination are discussed. It is noted, that the present protection has been proposed based on monitoring the currents ratio in the phases of the same name, and devoid of all the disadvantages of the conventional one, except for its use of current transformers with ferromagnetic cores. It is stated that the protections without current transformers construction problem is a fundamentally unresolved problem of relay protection. Three ways to solve it for parallel lines are proposed. The first and the second are to do it at the power supply side, the third one - at the receiving side. The first is to determine the damaged line by the time difference of reaching the set value by the currents in the same name phases, the line in which the current has reached the set value earlier is disconnected; the second is to control the angle between the differential current of the parallel lines and the current in each of the same name phases, the third is to control the time between the moments when the current in the line phase reaches the specified value. The circuits where these methods are implemented, are analyzed. With the help of mental modeling, their performance in various modes is confirmed.","PeriodicalId":285590,"journal":{"name":"2020 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115994496","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}

Due to its significance, security experts continue to improve the mechanism and the tools used to manage security issues. The revolution in computing and information technology has significantly affected how people deal with security. Computer vision application has been developed for security purposes, especially, by improving surveillance systems. Computer vision can manage face detection, motion detection, person identification, tracking, access control, and interpretation of movement. Most of these tasks can be used to improve security surveillance. Computer integrated systems can be used to identify strange behavior and aid security management. Forensic science involves the analysis of images to establish patterns. As a result, strategies aimed at utilizing computer vision focus on the improvement of image computation power of computer systems. Surveillance processes based on the use of cameras involve different phases: environmental design, discovery of movements, analysis and description of behaviors, organizing objects in motion, tracing as well as discovery of individuals. This paper seeks to analyze how computer systems can be trained to identify digital patterns in order to help in surveillance processes including tracking of strange behavior and crime.","PeriodicalId":285590,"journal":{"name":"2020 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124099837","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}
