Abstract Purpose A detailed assessment of the environmental impacts of the building requires a substantial amount of data that is time- and effort-consuming. However, limitation of the system boundary to certain materials and components can provide misleading impact calculation. In order to calculate the error gap between detailed and simplified assessments, the purpose of this article is to present a detailed calculation of the environmental impacts of the building by including in the system boundary, the technical, and electrical equipment. Method To that end, the environmental impacts of a laboratory and research building situated in Graz-Austria are assessed following the EN-15978 norm. Within the system boundaries of the study, the material and components of building fabric, technical, and electronic equipment for the building lifecycle stages of production, construction, replacement, operational energy and water, and end-of-life are considered. The input data regarding the quantity of materials is collected from the design and tendering documents, invoices, and from discussion with the head of the building’s construction site. Primary energy and global warming potential indicators are calculated on the basis of a functional unit of 1 m2 of energy reference area (ERA) per year, considering a reference building service life of 50 years. Results and discussion The primary energy indicator of the building is equal to 1698 MJ/m2ERA/year. The embodied impacts are found to be responsible for 28% of which 6.4% is due to technical and electronic equipment. Furthermore, the embodied impacts for the global warming potential, equal to 28.3 kg CO2e/m2ERA/year, are responsible for 73%. Together, technical and electrical equipment are the largest responsible aspects, accounting for 38% of the total impacts. Simplified and detailed result comparisons show a gap of 29% and 7.7% for global warming and primary energy indicators. These differences were from the embodied impacts and largely from the exclusion of electrical equipment from the study’s system boundary. Conclusions Technical and electrical equipment present a significant contribution to the overall environmental impacts of the building. Worthy of inclusion in the system boundary of the study, the environmental impacts of technical and electrical equipment must be calculated in detail or considered with a reliable ratio in the early design phase of the project. Further research is necessary to address the detailed impact calculation of the equipment and notably the minimization of their impacts.

Current Harmonics

The parameters of electrical network modes often do not meet the requirements of Russian GOST 32144-2013 and the guidelines of Vietnam. In the actual operating conditions while there is the non-sinusoidal mode in electrical networks voltage and current harmonics are present. Harmonics result in overheating and damage of power transformers since they cause additional active power losses. Additional losses lead to the additional heat release, accelerating the process of insulating paper, transformer oil and magnetic structure deterioration consequently shortening the service life of a power transformer. In this regard there arises a need to develop certain scientific methods that would help demonstrate that low power quality, for instance could lead to a decrease in the electrical equipment service life. Currently we see a development of automated systems for continuous monitoring of power quality indices and mode parameters of electrical networks. These systems could be supplemented by characteristics calculating programs that give out a warning upon detection of the adverse influence of voltage and current harmonics on various electrical equipment of both electric power providers and electric power consumers. A software program presented in the article may be used to predict the influence of voltage and current harmonics on power transformers.

The paper covers the ways of building foreign language competence of students majoring in electrical engineering in the process of their vocational training. The purpose of the article is the practical substantiation of the process of forming the future energy engineers’ foreign languagecompetence by means of project technology and carrying out diagnostic measures to check its effectiveness in foreign language learning. The methods used in this research are theoretical (analysis, comparison, systematization, generalization), empirical research methods (observations, surveys, pedagogical experiment), and statistical (non-parametric Pearson's criterion.). The results. The efficiency of project technology in the indicated process has been substantiated. A number of factors that determine the choice of such a learning technology has been specified, namely they are the following: student-oriented approach, foreign language learner autonomy, building project-oriented skills in specialty metalanguage, relationship between project work as a form of performing educational assignments and types of engineering activity. Author’s definition of project technology has been provided. By this notion a system of active and practical methods of learner-centered education aimed at programmed organization of students’ project activity, creation of educational projects that involve developing skills of independent knowledge acquisition, their practical handling, development of critical and creative thinking and key competences, is meant. The efficiency of project technology in the educational process has been experimentally verified by the example of developing foreign-language competence of students doing Master’s degree in electrical engineering. In order to determine the efficiency of project technology in the process of foreign language teaching to students in the master’s programme compared to traditional teaching methods, control groups and experimental groups with such attributes as reproductive properties, constructability and creativity were formed. Foreign language competence forming according to motivational, communication, professional, projecting and performance indicators was implemented in the process of executing profession-oriented projects. In order to assess the results of future power engineers’ project work, 100-point scale was developed. Conclusions. According to the results of the performed project work, it was determined that the level of foreign language competence in the experimental groups was higher than the one in the control groups. Generalized maturity indices of motivational, communication, professional, projecting and performance components in the control groups and in the experimental groups differed significantly. Group inhomogeneity and the significant differences were confirmed with the help of statistical non-parametric Pearson’s test χ². The obtained results of the pedagogical experiment have proved the efficiency of the suggested project technology and its rationale for implementing in the process of future electric power engineers’ foreign language teaching.

Impedance Characteristics

Voltage decrease and power loss in distribution lines of aircraft electric power system are harmful to the normal operation of electrical equipment and may even threaten the safety of aircraft. This study investigates how the gap distance (the distance between aircraft cables and aircraft skin) and voltage frequency (variable frequency power supply will be adopted for next generation aircraft) will affect the impedance of aircraft cables. To be more precise, the forming mechanism of cable resistance and inductance is illustrated in detail and their changing trends with frequency and gap distance are analyzed with the help of electromagnetic theoretical analysis. An aircraft cable simulation model is built with Maxwell 2D and the simulation results are consistent with the conclusions drawn from the theoretical analysis. The changing trends of the four core parameters of interest are analyzed: resistance, inductance, reactance, and impedance. The research results can be used as reference for the applications in Variable Speed Variable Frequency (VSVF) aircraft electric power system.
