SPbGASU graduates automate the power supply of construction sites
Technologies in the field of energy automation, energy saving, digital systems of the "smart home" do not stand still, and the Department of Electrical Power and Engineering of St. Petersburg State University of Architecture and Civil Engineering is trying to master new areas. Those are reflected in the final qualification works of students.
FQW Ruslana Barinova: block diagram of the implemented smart home system; block diagram of the controlling microcontroller
FQW Ruslana Barinova: implementation of the “smart home” control panel for the tablet
Ruslan Barinov’s work is dedicated to digital technologies for smart home systems. The Master’s degree student chose a non-traditional way, completing the development not on the basis of solutions that had already become standard, but on the basis of the CAN protocol, which appeared back in the mid-1980s and has been used in transport and industry. As a result, the cost of equipment for creating a “smart home” amounted to only about 25% compared to solutions with the use of tools typical for this sphere. This solution proposed by the graduate was implemented, showing its advantages and disadvantages that could not be identified at the design stage.
Mikhail Grachev’s FQW: isometry of the power supply system, an example of the arrangement of the electrical room
Mikhail Grachev, defending this year's his Bachelor's degree qualification in this speciality, dedicated his qualification work to the development of an electricity supply system with the use of Autodesk Revit software. This program has already found wide application in the educational process at SPbGASU, but due to the fact that the section on the calculation of electricians appeared in it one of the last, it only got to be used at the department of Electrical Power and Engineering only in the outgoing academic year.
“The development of the module for calculating the electrical part of buildings in this program has not yet been completed, many of the necessary functions have not been finalized,” Mikhail explains the situation about Revit. “Therefore, third-party manufacturers that release expansion packs for it are now helping out. But in the future, I hope the main developer will finalize the program."
Associate Professor at Department of Electrical Power and Engineering, Alexander Yepishkin, Candidate of Engineering, who supervised the FQWs of Ruslan Barinov and Mikhail Grachev, believes that it is necessary to undertake new areas, despite the fact that often there are no textbooks and research publications on those, but only technical documentation. It is always easier to write a graduate work on an already known topic developed by others, but the choice of a new area opens up opportunities for a graduate to further work in a promising field.
Valeria Emmerich’s FQW: building lighting plan
Valeria Emmerich’s FQW: profitability of home automation; relay actuator 2316.16 REGHE JUNG
Valeria Emmerich in her Master’s degree FQW developed a methodology for assessing the effectiveness of control systems in intellectual buildings. She suggests combining economic and technical studies conducted to evaluate energy efficiency in smart homes into a single algorithm. The solution proposed by Valeria is innovative for Russia, since we are only developing this area and there is no specific methodology for assessing the effectiveness of such systems. As a result of her work, the graduate has demonstrated that intelligent systems reduce energy consumption in buildings by 21%.
FQW of Bachelor’s degree program graduate Anton Duboysky is dedicated to the development of an automated control system within one apartment in order to optimize energy consumption. Thanks to the efficient management of lighting, heating and air conditioning, you can significantly reduce energy costs, as well as increase comfort for residents. In the course of the work, the author compiled a table where the existing automation systems are ranked by energy saving level, which made it possible to choose the optimal system for this project, i.e., KNX.
“Among the major for choosing a system, along with reliability and functionality, are the financial aspects, since the high costs of the system greatly reduce its effectiveness as a way to save,” Anton explains.
Today, home automation systems are widely used in many countries, but in Russia this area is progressing too slowly. The student got interested in the problem, and after analyzing the dependence of the system payback on the cost of electricity, he came to the conclusion that the demand for such home automation systems would sharply increase in the event of a possible increase in the price of electricity in the future.
Professor of the Department of Electrical Power and Engineering, Ravil Safiullin, Dr. of Engineering, who supervised the works of the Master’s degree student Valeria Emmerich and the Bachelor’s degree student Anton Duboysky, believes that they were performed using modern digital technologies and system analysis and with the account of the current situation in the domestic energy sector. Graduates identified problems, analyzed the operation of systems, developed and scientifically substantiated evaluation methods and practical recommendations. An independent theoretical analysis of the studied problems revealed the research interest of the graduates. Based on the results of training and defense, the state examination commission offered Valeria Emmerich further studying in postgraduate school.
Head of the Department of Electric Power and Electrical Engineering, Viktor Reznichenko, Candidate of Engineering, believes that these graduation works are especially relevant in the context of the implementation of the Smart City project, which is aimed at improving the energy efficiency of facilities under construction, for which knowledge in the field of automation, which graduates have successfully demonstrated, is essential.
