SOLAR POWER SYSTEMS WITH GUARANTEED POWER SUPPLY

abstract 1241610097 issue 124 pp. 1465 – 1478 30.12.2016 ru 434
The 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 principal technical characteristics of modern solar and regular batteries of the best companies were compared. We have also given recommendations for improving the operational characteristics of solar energy systems of guaranteed power supply, in which special attention is paid to technical characteristics of the main functional elements of the system, including electromagnetic compatibility

THE CHOICE OF THE GENERATOR AND ELECTRICITY STABILIZATION FOR SMALL HYDROPOWER PLANTS

abstract 1121508069 issue 112 pp. 964 – 973 30.10.2015 ru 910
The article analyzes the main characteristics of the electricity generators to use them as a part of small hydroelectric power plants. It is shown, that contactless asynchronous generators in comparison with synchronous generators and DC generators have improved their operational and technical characteristics, and above all, their reliability and performance efficiency. We have shown graphic dependences of the cost and the weight of power generators. It is proposed using direct frequency converter as a stabilizer of parameters of asynchronous generator of electricity, used as a source of electricity for small hydropower plants. The article explains the features of the work and the choice of parameters for generators, working together with the direct frequency converters. The authors have revealed some aspects of the work of direct frequency converters with natural commutation and with adjustable phase angle, including their advantages and disadvantages. The article also presents block diagrams for small hydroelectric power plants, made with the help of asynchronous generators and direct frequency converters
