TO THE QUESTION OF IMPROVING THE QUALITY OF DISSERTATIONS AND OPTIMIZATION OF DISSERTATION COUNCILS
Description
It is known, that the development of fundamental and applied sciences, besides research institutes, are the universities. Integration of scientific researches of higher school into production occurs in many forms and can be largely determined by the quality of the training, including defense of thesis, research and teaching staff of the university. The article criticized the Ministry of education and science of the Russian Federation, and the higher attestation Commission of Russian Academy of Sciences aimed at improving the quality of work of dissertation councils and of the level of theses, based on the optimization of the network of dissertation councils, including their union, raising the level of members of dissertation councils. We have suggested a number of measures and specific requirements for the content of dissertations and supervisors of theses, official opponents of the thesis councils and their members, employees of the HAC. Introduction of considered proposals concerning increasing the level of theses into practice of work of dissertation councils, one set of measures will allow to optimize the network of dissertation councils and to improve the quality of their work

ABOUT INCREASING THE PRESTIGE OF HIGHER TECHNICAL PROFESSIONAL EDUCATION IN RUSSIA
Description
The article elucidates reasons for the falling prestige of higher technical professional education in Russia and based on their analysis we propose measures aimed at raising the status of technical specialists. These activities include: development of a strategic plan of development of higher professional education, a system of vocational guidance of graduates of secondary educational institutions; improvement of quality of preparation of scientific-pedagogical staff and development of effective system of training of teachers; the quality of the educational process and development of effective system of training of graduates; development of objective criteria for assessing the effectiveness of universities; development of a system of Patriotic education of students of secondary and higher educational institutions; increase of salaries of specialists, influencing the country's economic development, the status and prestige of the profession of high school teacher. It is necessary to develop a strategic plan for the development of higher professional education urgently since the first part of young professionals will be ready only after 4 years. Nevertheless, retraining and advanced training of specialists of technical and technological disciplines needed for the development of modern techniques and technologies, including foreign ones, we can start today. The implementation of the considered measures will allow to raise prestige of higher technical professional education and quality training of students

VOLTAGE REGULATORS OF SYNCHRONOUS GENERATORS
Description
Synchronous generators are the primary source of electrical power autonomous electrosupply systems, including backup systems. They are also used in a structure of rotating electricity converters and are widely used in renewable energy as part of wind power plants of small, mini and micro hydroelectric plants. Increasing the speed and the accuracy of the system of the voltage regulation of synchronous generators is possible due to the development of combined systems containing more stabilizers. The article illustrates the functional schemes of circuit voltage stabilizers and frequency synchronous generators (with electromagnetic excitation and permanent magnet excitation) and describes the features of their work, including two and three-aggregate rotating converters of electricity used in uninterruptible power supply systems. To improve the technical characteristics of the system of stabilization we have proposed functional solutions for stabilizers of synchronous generators made on the base of direct frequency converters and using a transformer with a rotating magnetic field. To improve the reliability of and to improve the operational characteristics of the autonomous independent sources of electricity we suggest creating the main functional blocks and the elements of the stabilization system in a modular way. The functional circuit solutions of voltage regulators of synchronous generators and the characteristics of their work considered in the article, are able to improve the efficiency of pre-design work in the development of new technical solutions for stabilizing the voltage and the frequency in synchronous generators of electrosupply autonomous systems

PROSPECTS OF SMALL HYDROPOWER PLANTS IN THE PIEDMONT AND MOUNTAIN STREAMS
Description
The article reveals the advantages of low energy in comparison with other renewable energy sources. It is shown that broad prospects are visible for small (100 - 1000 kW) and micro hydropower plants (up to 100 kW) when used in the foothill and mountain areas. At the same time, the construction of hydropower plants of sleeve-type has improved the operational and technical characteristics, among other types of small-scale power plants. The article presents main analytical expressions for calculating hydroelectric power generator and it has built graphic dependences for the power generator of pressure and water flow. To improve the performance of small hydroelectric power plants we have proposed using unregulated water turbine and non-contact induction generator in their construction, thus, we could stabilize voltage and frequency directly by the frequency converter. Depending on the requirements of consumers to power supply reliability and electricity quality, we have offered several options for structural and circuit solutions of autonomous systems of electrosupply, made using small hydroelectric power plants. Thus, we can greatly enhance the efficiency of such systems if they are used with other types of renewable sources, such as windfarms or solar power plants
