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 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
This article discusses the basic analytical expressions for calculation the energy potential and cost-effectiveness of wind energy
The article discusses the functional diagram universal modular inverter and stabilizer parameters of electric power with improved operational and technical characteristics
