Autonomous power supply system for outdoor illumination of residential areas in the territory of Ukraine
Journal Title: Вісник Тернопільського національного технічного університету - Year 2018, Vol 89, Issue 1
Abstract
The methodology and the calculation of the autonomous power supply system for outdoor illumination using solar batteries of KV 250M type, Li-ion batteries of LP48100ES type and the control system consisting of the MPPT controller, controlling battery charge - discharge and inverter of Growatt 10000HY type are investigated. The technical and economic calculation of the autonomous energy system for the outdoor illumination of residential areas with the population of more than 1 million (Kyiv city) and with the population up to 10 thousand (Lanovtsi city) is carried out. The analytical dependences of energy consumed by outdoor illumination on the number of lighting points for different residential areas of Ternopil region are obtained
