CLASSIFICATION AND BASIC METHODS OF CONSTRUCTING SOLAR POWER PLANTS
Description
The high speed of solar energy development in the modern world allows us to assert that in the near future it will become one of the main sources of electricity. The authors describe a classification of solar power plants, which can be of two types – thermodynamic and photovoltaic, as well as the features of design and operation of these plants. There is a structural and schematic solution of autonomous solar power stations and ones operating in parallel with the external power grid. The features of their design and operation, including the main advantages and disadvantages were shown. It is shown that to improve the reliability, including uninterrupted power supply, a promising direction is the development of combined systems which in addition to the solar power plant may use wind power, gas or diesel power, etc. In addition, such stations may provide power from the external power supply. We have given one of the variants of structural designs of combined systems of energy and disclosed recommendations for the design of energy-efficient combined systems of power supply, made using renewable and conventional sources of electricity. The final version of the combined system of electricity supply and the degree of participation of traditional and renewable energy sources in electricity production is determined on the basis of the analysis of the energy balance and electromagnetic compatibility of the main functional elements of the system

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

POWER SOURCES OF OPERATION, CONTROL AND PROTECTION DEVICES
Description
Currently operating in autonomous systems of power supply DC voltages power sources are secondary sources for operation devices, protection and control of generators, motors, stabilizers and inverters have relatively low operational performance. The work proposes to improve the weight and the size of power supplies to apply a high frequency link in their designs. We provide structural designs and the peculiarities of operation of secondary power sources with a high frequency link. This article discusses the fundamental electrical circuits of pulse regulators, converters based on resonant inverters and transformers with rotating magnetic field. The use of resonant inverters in power sources will significantly improve their weight and overall dimensions. In addition, the use of secondary sources of supply for transformers with rotating magnetic field will simplify their design and reduce the level of electromagnetic interference generated by semiconductor devices. The features of operation of pulsed regulators and prospective structuralschematics converters discussed in the article, performed on resonant inverters and transformers with rotating magnetic field, will increase the effectiveness of pre-work on the development of secondary power sources with improved operational and technical characteristics for devices of operating, control and protection
