TPU creates an advanced system simulating emergency in electric power system

Scientists of Tomsk Polytechnic University have created a decision support system (DSS) for dispatching personnel of electric power systems (EPS). The system allows dispatchers to quickly test their actions on the management of the EPS, to control and evaluate their consequences using a digital simulator in a regime faster than real-time.

The article devoted to the research work is published in the IEEE Transactions on Power Systems (Q1, IF 6.074) academic journal, one of the most peer-reviewed journals in energy, energy technology, electrical engineering and electronics industries.

“An EPS is some kind of a living organism within that changes are permanently and continually taking place. In order for this organism to function properly and without any failures, it must be controlled. This extremely complicated task is carried out by dispatching personnel. Moreover, wrong or belated actions of a dispatcher can exacerbate an emergency,” Aleksey Suvorov, Associate Professor of the TPU Division for Power and Electrical Engineering, one of the authors of the article, says.

He adds that the DSS is a continuation of the research work for a multiprocessor system for real-time simulation of the EPS. For this development, a research team of young scientists from the TPU Research Laboratory for Power Grid Simulation, including Mikhail Andreev, Nikolay Ruban, Aleksey Suvorov and Ruslan Ufa, was conferred with the Russian Federation Government Prize in Science and Technology for Young Scientists. The comprehensive simulation system allows obtaining a huge volume of information on the operation of the EPS. The data are kept on the server. The DSS operates with these data.

“A DSS has been created based on a hybrid approach to EPS simulation that was developed by Alexander Gusev, Professor of the TPU Division for Power and Electrical Engineering. Its core lies in the combination of existing simulation techniques (analog, physical and digital) and the use of the best properties and capabilities of each of the techniques. Using a DSS, methodically accurate simulation is implemented in real time of the EPS of any scale and complication,” the scientist explains.

“The system is actually an alternative to a real EPS, its digital simulator. Furthermore, due to the properties of a hybrid approach, a simulation capability faster than in real time implemented. On the current element base, it was possible to speed up by five folds. It allows the operator to test several case scenarios, to choose the most effective one, to adjust a regime state and only after that to act in a real EPS, reducing a possible negative effect from his actions,” he continues.

All components of the system, including special software, are developed at TPU. The system effectiveness was tested at a real EPS of the Tomsk Region.

“The DSS simultaneously operates with the EPS and collects data from the operative-information complex (OIC). The OIC monitors a regime of the EPS, collects the data about voltage, power and controls how the system operates,” he says.

“To test the system, we created a special emulator simulated the OIC. Using the emulator, an emergency visible for the dispatcher and the system was simulated. The DSS software contains all required algorithms and case scenarios. The dispatchers possess very strict regulatory directions regarding what actions must be taken in any situation,” Aleksey elaborates.

“According to the occurred emergency, the DSS processes the incoming information and suggests patterns based on the direction. Besides, due to the fast simulation, the dispatcher possesses more time to control and take the rightest pattern.”

The effectiveness of the system operation was also experimentally tested jointly with scientists from the Indian Institutes of Technology (Roorkee).

Betting on drones as smart agricultural tools for pesticide use in farms

Drones could soon be adopted as essential tools for various agricultural tasks; however, with respect to their use in farm management, research is still lacking. To address this issue, researchers in Japan compared drones to well-established technologies for spraying pesticide over rice paddy fields.

Using statistical data, the researchers explore both advantages and limitations of drones and whether they currently offer an edge regarding costs, capacity, and management efficiency.

“Following recent technological demonstrations and verifications at field sites, there is an increasing need for farm management research of smart agricultural technology including cost and efficiency analyses; this is essential for its implementation in farms,” explains Yuna Seo, who is Junior Associate Professor at Tokyo University of Science, Japan.

In an effort to address this knowledge gap, Seo led a recent study published in MDPI’s
Sustainability
in which she, with her student Shotaro Umeda, compared different pesticide spraying technologies using realistic data.

More specifically, the researchers evaluated and compared the costs, working capacity, and management efficiency of drones versus remote-controlled (RC) helicopters and tractor-mounted boom sprayers for preventively spraying pesticides over rice paddies. They made these comparisons for seven different paddy field areas to take into account differences in scale for each method.

In terms of pest-control costs, the UAVs were only slightly less expensive per unit area than the boom sprayers, mainly due to the low price of drones and savings in fuel. In this regard, the RC helicopters were much more expensive.

“Although the purchase cost of boom sprayers is almost double that of UAVs, the fixed costs of both end up being similar because of the high operation, maintenance and repair costs of drones, which are notorious obstacles in UAV introduction and adoption,” remarks Seo.

As for the working capacity, RC helicopters could cover much more area per hour than both drones and boom sprayers. Still, drones had a slight advantage in daily area coverage over boom sprayers.

Finally, to explore the management efficiency of each method, the researchers used a technique called “data envelopment analysis,” which is widely used in economy and operations management to benchmark the performance of manufacturing and service operations.

The results indicated that both boom sprayers and UAVs reached
maximum or near-maximum efficiency for most paddy areas, while RC helicopters
were much less efficient.

Overall, this study showcased the benefits of drones as tools for rice production and compared them to other well-established technologies.   But, the use of drones in agriculture is not without limitations, which should be addressed in the future, such as the modification of aviation laws that forbid higher pesticide payloads on drones, as well as maintenance costs.

“The total costs and efficiency of UAVs would be comparable to that of boom sprayers, which is not a hindrance for farmers wanting to switch to drones. Therefore, technological advances and deregulation are necessary to expand the use of UAVs while meeting safety measures and ensuring applicability,” explains Seo.

In conclusion, this study highlights both the advantages and limitations of using drones as agricultural tools. Still, there is no doubt that smart agriculture as a whole could greatly alleviate the labour shortage problems in countries with a rapidly ageing population, of which Japan is a prime example.

TPU scientists find method to more effectively predict properties of isotopologues of chlorine dioxide

Scientists of Tomsk Polytechnic University has conducted research on the 35ClO2 isotope and developed a mathematical model and software, which allow predicting characteristics by 10 folds more accurate than already known results. The research work was conducted by a research team of Russian, German and Swiss scientists. The research findings are published in the Physical Chemistry Chemical Physics (IF: 3,4; Q1) academic journal and listed as one of the best articles.

The ClO2 molecule is extremely important for medicine and biophysics, as well as for the Earth atmosphere. It is used in medicine for disinfection and sterilization. On a global scale, ClO2 plays one of the crucial roles in the formation and migration of ozone holes.

“The theoretical background for nonlinear molecules in so-called non-singlet electronic states, including ClO2, has been poorly developed until very recently. To study such molecules, scientists use a mathematical apparatus for linear molecules. As the molecule and its structure are different, there are large observational errors,” Oleg Ulenekov, Professor of the TPU Research School of High-Energy Physics, the co-author of the article, says.

“We created a mathematical model that takes into account subtle effects, the interaction of rotations and spin-rotational interactions in nonlinear molecules. The mathematical model gives the results with high accuracy that allows obtaining unique data and, the most important is that, predicting the properties of molecules with high accuracy,” Oleg continues.

The TPU scientists compiled the mathematical model of the 35ClO2 molecule for double electronic states and included it in computer codes. This software application can read and predict experimental data, that is properties of a molecule in the given range and its state transitions. Spectral analysis of the molecule based on the compiled model possesses the result by 10 folds accurate than already known ones.

Based on the created model, the scientists conducted an analysis of rotational-vibrational spectra in a degenerate electronic state. The experimental basis of the research work was conducted in the Laboratory for Molecular Spectroscopy at Technical University of Braunschweig (Germany) and ETH Zurich (Switzerland).

According to the scientists, the compiled model possesses a more unique character and it can be developed and adapted to the other ranges.

“Having published the results, the editorial staff of the journal reported that the article was selected and put in the hot topic section, the so-called pool of the best articles. Such recognition of the work of the international research team is very important and valuable. We are planning to continue the research work and apply the model for analysis of the 37ClO2 isotope,” Elena Bekhtereva and Olga Gromova, Professors of the TPU Research School of High-Energy Physics, the co-authors of the article, add.

Thammasat University invents UVC sterilizer pole to kill coronavirus

Thammasat  University has invented a new innovation “UVC Sterilizer Pole” that can kill the COVID-19 virus within 20 minutes. It is suitable for large area usage such as open markets and shopping malls.

Thammasat School of Engineering (TSE) by Associate Professor Dr Thira Jiasiripongkul, Dean of TSE and Assoc.Prof.Dr.Sirima Mongkolsomlit, Assistant Dean for Student Affairs  at Faculty of Public Health, Thammasat University (TU) says, “UVC Sterilizer Pole is a 1.2-meter height pillar with lightbulbs on 4 sides that can destroy the outer layer of COVID-19 virus. The lightbulbs are installed at an angle of 20 degree so that it can radiate onto the floor or road surface.

“TSE UVC Sterilizer” is developed and created by Assistant Professor Dr Pradya Prempaneerach from the department of Mechanical Engineering, Thammasat School of Engineering (TSE). He has also developed “Tham – UV Clean”, a UVC chamber for face mask sterilizing to support healthcare worker’s work during the first wave of COVID-19 pandemic.

Assistant Professor Dr Pradya Prempaneerach reveals, “This UVC sterilizer can completely inactivate COVID-19 virus in an open area. UVC is most effective at killing germs but it can also be dangerous to humans as it can irritate skins and affect your eyesight when you look at it even briefly.”

“We design it with the countdown timer. When the machine is turned on, it will start working after 5-10 minutes later so that the user can step back in time. After that, the machine will work autonomically for 20 minutes to sterilize the surface and the radiation length is about 2 meters away from the installation area.”, said Dr Pradya.

“The benefit of using UVC light to sterilize is that virus will be inactivated whenever the virus is exposed to the light. Unlike wiping with alcohol, it requires less human labor. However, the inactivation of the virus on surfaces may not be effective because of the blocking of light in some areas such as behind the surface area. The production cost of this UVC sterilizer is around 3,000-4,000 baht.”, said Dr Thira.

Associate Professor Dr Gasinee Witoonchart, TU’s Rector, states, “As a university for people that has centers around the country’s main strategic areas, TU always focuses on the improvement of quality of life along with academic services. Especially in the new wave of COVID-19 pandemic, Pathum Thani province was affected so badly that the market and the area were shut down and heavily controlled. Therefore, it is Thammasat’s mission to help relieve this problem.”

TU professors have collaboratively invented and produced 4 UVC sterilizer pole. Recently, the university gave them to Emergency Operation Center COVID-19, Pornpat market, to sterilize risk areas in the market.

“Professors and TSE staff offered their prompt support and only spent 2-3 days to produce the machine after coordinating with the Office of Disease Prevention and Control, Region 4. As a Rector, I would like to reassure that TU will continue to diligently support all sectors to fight against COVID-19. We believe that Thailand will overcome this disease outbreak for sure.”, said Associate Professor Gasinee Witoonchart.

PhD student from Vietnam talks about his research career and studying at Mining University

Vietnam is one of Russia’s key partners in the Asia-Pacific region, with scientific, technological and educational cooperation between our countries going through intensive development.

Rossotrudnichestvo, an organisation responsible for promoting Russian education services abroad, allocates nearly 1,000 quotas to Vietnamese nationals annually, more than any other non-CIS country gets. Applicants who are granted quotas can commence free studies in a university of their choice. 

Le Thanh Binh works at the Institute of Energy & Mining Mechanical Engineering (IEMM). He recently arrived in St. Petersburg to present his PhD thesis. 

“After completing my master’s at Hanoi University of Science and Technology in 2006, I was offered to work at the materials science laboratory in IEMM. This is a research institute that is part of Vinacomin, Vietnam’s largest mining company; it specialises in manufacturing and repairing mining machinery and spare parts. Five years later, I was appointed the Deputy Director of the Testing Center. This is when I felt the need to upgrade my skills,” says the student.

“The quality of higher education in Vietnam has improved a lot lately. Still, it is incomparable to that of what developed countries offer – G7 and Russia notably.”

“The Assistant Director of the Institute suggested that I choose his alma mater – St. Petersburg Mining University. By the way, many of my colleagues graduated from it. Soon I learnt there was a cooperation programme between the two institutions. Mining University offered education in the field that I was interested in. I also found out about scholarship opportunities. So the decision was made. In 2013, I became a PhD student in the ‘Mining Machines’ programme,” he adds.

Only 3% of international students in Russia are receiving postgraduate education – 10,000 in total. The overall number of students from abroad amounts to 310,000. Le Thanh Binh thinks it is hardly surprising since students expect to start working right after they graduate, aiming for financial independence.

“If you engage yourself in scientific research, the duration of studies rises by three to four years. Few can afford it. PhD stipends in Russia are generally not that high, remaining below the level of an average salary. In that sense, Mining University is an exception,” he says.

“Of course, locals also have it easier than foreigners, who have to pay their living costs and cannot rely on family support. That is why international students usually don’t proceed to further education after getting their bachelors’ or masters’. That said, in Vietnam, we don’t even have that – PhD programmes are fee-based, with a fee per academic year ranging between $15-20 thousand,” stresses out the researcher.

Today’s Vietnam is particularly interested in training engineers. Therefore, the advancement of technical education has become a national priority. Tens of thousands of high-school graduates enrol in universities of applied sciences, and thousands leave the country to explore education opportunities abroad. 

“Our domestic economy greatly depends on the mining of coal, granite, limestone, and the extraction of oil and gas. Hence, the development of mechanical engineering, a supporting industry, positively affects the mineral resources sector on the whole,” explains Le Thanh Binh.

“In Russia, I was able to delve into research areas relevant to my country. I wrote my thesis on improving the durability of impact tools, focusing mainly on the hydraulic hammer. We actively use it in quarries and mines. Guided by my teachers from Mining University, I wrote scientific articles. I visited factories producing hydraulic breakers, tested various models whilst performing mining operations both in Russia and Vietnam,” he continues.

By 2018, the Vietnamese scientist had completed most of his studies, with only a thesis paper left unfinished. He returned to Hanoi to work at IEMM and proceeded to write his thesis. Soon he was promoted to Deputy Head of the R&D department, and now he is responsible for governing research on optimisation of mining machinery and manufacture of new products.

“Academic degree is what I need to advance my career further. By the end of this month, I should be a Candidate of Sciences (analogous to a Doctor of Philosophy). Then I’ll be able to apply for the position of head of R&D.

Vinacomin takes Russian education seriously. So far, 15 employees of our Institute pursued PhD studies at Mining University. Two more have been sent to study by me personally. In the future, I plan to facilitate the educational and scientific cooperation between the corporation I work for and the University. Hopefully, it will result in new opportunities for joint research, sharing experiences, and engineering and scientific training. I suppose it will be by no means less worthy contribution to international relations had I stayed in Russia,” sums up the soon-to-be graduate.
