Abstract

The purpose of the work is to develop a methodology for designing a stand-alone power supply system based on photovoltaic (PV) converters for technical security equipment power supply. The object of the study is a PV converter - based stand-alone power supply system. Energy storage units, which are widely used in the designing of power supply systems for power supply of technical security equipment are presented. A methodology for designing a power supply system is used, which takes into account the integral effect of solar insolation, ambient temperature in the range from - 40°C to +50°C, temperature of a PV module and a storage battery; PV module capacity; requirements for independent operation of technical security equipment; electrical characteristics of the solar charge controller (rated open-circuit voltage and rated charge current). To calculate the total solar insolation arriving at the surface of a photovoltaic module, the Kastrov model is used for calculating direct solar radiation; the Berlage model is used for calculating the scattered solar energy and the Berland model is used for calculating insolation in cloudy conditions. The studies of lithium-titanate storage batteries have been carried out in the climate chamber and a corresponding mathematical model has been developed for the temperature-dependent capacity of the battery. To determine solar insolation falling on the tilted surface of the PV module the software has been developed in the C# programming language. The designed PV module-based power supply system provides an independent uninterrupted continuous power supply of equipment under constant consumption of no more than 115.2 Wh per day by technical security equipment. The results of the work can be used in the development of a stand-alone power supply system for power supply of technical security equipment, security and control.
