The paper consist of an introduction, four chapters, general conclusions and recommendations, bibliography of 197 titles, 12 appendixes, 138 pages (up to bibliography), 23 figures and 32 tables. The obtained results are published in 15 scientific papers.
The purpose and objectives of the thesis consists in determining the influence of random factors on the reliability of the systems of power distribution voltage 6-10 KV, in the Republic of Moldova. Research has been focused on the following major objectives of the work: assessment of the reliability of the actual distribution of electricity in the Republic of Moldova; preparation of the method for the estimation of influence of random factors on the reliability of systems; the use of the developed method in analysis and optimization of the reliability of researched real systems; development of measures to ensure the level of reliability of systems for the distribution of electricity, given the influence of random factors are.
The scientific novelty of the results obtained: consists in solving of an important scientific problem and namely the elaboration of the method for evaluating the influence of random factors, both determined and undetermined, on the reliability of systems for power distribution and development of measures to ensure the function reliability of these systems.
The solved scientific problemis the estimation of ponderability random factors on the reliability of functioning of the elements of the distribution systems and determination of the prognosis mechanism and ensurance of the reliability level of electric energy supply to consumers. Theoretical significance lies in the determination of influence of different random factors on the reliability of the systems of distribution of electricity; the frequency of appearance of these factors in dependence of geographic location of the season; the weighting of concerned factors in the variation of indicators on different periods.
The applied value of the work is ensured by experimental and theoretical guidance on securing the reliability of systems for the distribution of electricity; the use of the results obtained in the practice of distribution systems operation and to improve teaching and learning process of students from technical specialties.
The implementation of scientific results: scientific results were implemented in the North DES
and MOLDELECTRICA COMPANIES and in curricula of the MOLDOVA STATE AGRARIAN
UNIVERSITY for training of students and master students from specializations with electric profile.
