SOLAR POWER SYSTEMS WITH GUARANTEED POWER SUPPLY
DescriptionThe article discusses the structural schematics of solar energy systems, providing guaranteed power supply to electricity consumers with priority for consumers of the 1st category. The work describes main functions performed by modern energy systems. It is shown that nowadays solar power systems of uninterruptable power supply are classified into three types: independent; hybrid (combined); intellectual. We have given the structural scheme of solar systems power systems of uninterruptable power supply and the features of their work. The article describes a monitoring system, carrying out functions of control and measurement of parameters of the power system depends on its performance. The economic performance of a solar power system has been influenced essentially by the cost of solar and accumulator batteries.

THE RESULTS OF THE REFORM OF THE EDUCATION SYSTEM IN RUSSIA
DescriptionOne of the main tasks is the improvement of the education system, the quality of which depends on the level of economic development of the country. In Russia, for more than 10 years there has been a continuously reformed educational system. This is due to Russia's accession (in 2003) to the group of countries – participants of the Bologna Declaration, involving the convergence and harmonization of education systems in European countries with the aim of creating a unified educational space. The article describes the main positions that are subject to a quality assessment of education from foreign universities; we have also revealed the reasons for the low world rating of Russian universities. At present, the education system of the country should facilitate accelerated development of the economy of the state in the first place. This work reveals the shortcomings of the main reforms related to the implementation of CSE in secondary educational institutions, the bureaucratization of the higher education system that resulted in time reduction of contact of the work of students with teachers, and as a result – deterioration of quality of preparation of graduates. We have also revealed the causes of the current situation and the main directions that will contribute to the development of the education system in Russia. These areas are the development of: a strategic plan for the development of higher education; a training system worthy contingent of higher education institutions; an effective system of preparation of students and evaluation of the quality of their knowledge and labor potential; a system of training for scientificpedagogical personnel and improving their qualification; assessment criteria of effectiveness and ability of educational institutions to provide quality knowledge

THE CONCEPT OF UNINTERRUPTED POWER SUPPLY SYSTEMS
DescriptionWe have revealed the main reasons for interruptions in power supply to consumers of electricity. To improve the reliability and the efficiency of power supply for responsible consumers, we have proposed to develop energy efficient combined energy-saving systems for uninterrupted power supply with use of renewable energy sources. The article lists major principles of the development of such systems; it shows the necessity of constructing a generalized schema that contains the possible types and the sources of electric power converters. It also reveals the modern requirements to systems of uninterrupted energy supply. To improve the operational and technical characteristics of the uninterruptible power supply, it has been proposed to use a new circuitry that includes a contactless power generators, the direct frequency converters used to stabilize the voltage and frequency of the current generators of wind turbines, static converters made with the use of single-phase transformers with rotating magnetic field, universal static converters that can operate in the regimes of known types of converters. The article presents features of the modular construction of systems of uninterrupted energy supply and optimization of their structural decisions on key performance criteria. It shows the algorithm of synthesis of structural designs of combined systems of uninterrupted power supply. An important step for further research with the aim of improving operational and technical characteristics of the combination of uninterrupted power supply systems is the mathematical modeling of physical processes in power circuits of the system in both normal and emergency modes of operation

ABOUT THE NEED TO CHANGE THE BURDEN STANDARDS FOR PEDAGOGICAL WORK OF FACULTY STAFF
DescriptionThe article reveals the content of pedagogical work activities for teaching staff in the main activities of the Department (academic, educational, methodical, scientific and organizational-methodical work). We have offered a rational standard time for their quality execution, allowing improving the quality of training of university graduates. It is proposed to consider additional classes and consultations in the burden time of teachers, as well as the norms of time for preparation for publishing educational and scientific literature, development of training, methodological, logistical and organizational-methodical work. It is shown, that the participation of teachers in researches and development with the aim of earning money for the University reduces the level of the educational process. To improve the quality of training of students, we have offered a number of key measures that needed to be organized by the Ministry of education and science of the Russian Federation, and also, by employees of the administrative apparatus of universities

THE NEED FOR THE USE OF RENEWABLE ENERGY SOURCES
DescriptionThe article reveals main reasons for developing tendencies to the using of new types of energy, which are limited supply of traditional fuels and environmental problems associated with its processing. It is shown that new forms of energy plays an important role in the energy supply of many countries of the world, and in the future they can become the main sources of energy to meet the growing needs of the global economy. We reveal main reasons of the increasing interest in renewable energy, and we show the obvious prospects of their use, due to two factors. First, according to experts, the global reserves of traditional fuels are limited, and secondly, this was evidenced by the investments of leading countries in this promising industry. The article lists reasons for the need for the use of renewable energy sources in Russia. Increased consumption of natural resources has become a real threat to the security of the life of human society. The basis of solving modern social and environmental problems is a transition to a regulated process of safe use of natural energy potential to meet the vital needs of people not only in the coming decades, but in the long run. It is concluded, that the determining condition for the development of the human civilization at present and in the future would be the level of natural resources which ensures the needs of the population without making harm to the environment

THE METHODS OF ASSESSING THE QUALITY OF KNOWLEDGE AND LABOR POTENTIAL OF UNIVERSITY GRADUATES
DescriptionKey indicators for employers are the quality of knowledge of graduates and their readiness for practice. The article suggests some methods of assessing the quality of knowledge and labor potential of graduates. Because the quality of training generally depends on the qualification of the faculty, the quality of students' knowledge is to be determined with the results of their learning and the qualification of the teachers who conducted their classes and supervised their final qualifying works. The author's analytical expressions for determining the quality of knowledge and labor potential of graduates, allow employers to choose specialists particularly required for their industry. However, for employers the rate of knowledge and labor potential of graduates of universities are indicative rates. In order to determine the choice of specific graduates, on the University's website starting from the 3rd year of a bachelor degree, we should post the information about the rating of individual students on educational and labor activity. The ratios determine the quality of knowledge of graduates and their labor potential, as well as reviews of employers should be the main indicators for the Ministry of education and science of the Russian Federation, on the basis of which we may assess the effectiveness of the universities, determine their ranking and generate a state order for training of specialists in higher education institutions

THE SYSTEM OF KNOWLEDGE ASSESSMENT AND RATING OF TESTING OF STUDENTS
DescriptionAn important question is increasing objectivity in evaluation of current and residual knowledge of students on the subjects. Based on these assessments, teachers will adjust the work program and calendarthematic plan on discipline, forms and methods of teaching in order to ensure a high level of knowledge, allowing making necessary competence and skills of future specialists. The article proposes the evaluation system of students ' knowledge and determines their rankings, taking into account the qualifications of the teachers who taught their classes. Knowledge assessment might be defined as just one discipline, or as all the across disciplines for a semester, academic year and study period. The knowledge of students on discipline is estimated on the results of the test tasks based on current estimates obtained in a semester, and examination grades. We have reviewed the quality assessment system of students ' knowledge and determined their rating; it will increase the credibility of the evaluation. In addition, it increases the effectiveness of the educational process, since the evaluation of students ' knowledge and skills of teachers, will help heads of departments and deans to make decisions about the professional development of teachers, showed poor results
