Дослідження втрат енергії в сонячній електростанції на тяговій підстанції

Abstract

UA: Проведено аналіз втрат в сонячній електростанції постійного струму № 18 м. Зміїв Харківського регіону зі всіма кліматичними умовами даного регіону. Проаналізовано показники енергоефективності інверторів, які використовують на даних сонячних електростанціях. Згідно з експериментальними даними на основі програмного комплексу PVsyst виміряно втрати енергії та проведений розрахунок зменшення викидів CO2 в сонячній електростанції.

EN: An analysis of losses in a solar power plant of direct current № 18 с. Zmiiv, Kharkiv region with all climatic conditions of this region. The energy efficiency indicators of inverters used in these solar power plants are analyzed. According to experimental data based on the software package PVsyst measured energy losses generated by a solar power plant. Connecting the SES to the mains can improve the voltage levels at the system nodes, but it is necessary to provide a power reserve in the system to cover the power deficit in the event of a sudden shutdown due to natural factors. To analyze the energy losses of solar energy, the software package PVsyst was used, which allows you to analyze the parameters of electricity losses with the display of loss diagrams for the year and the dependence of the amount of losses in electricity generation by solar panels. PVsyst software is used to calculate the output power, performance, and total loss of a station connected to the network. Losses calculated by PVsyst software include two types: PV array loss and System loss. After analyzing research conducted in Ukraine and other European countries, it is possible to conclude that the impact of poor quality electricity on electrical equipment is quite significant, and the study of the impact of unconventional generation sources on electricity quality indicators will identify ways to reduce electricity losses and increase electricity life equipment. The efficiency of solar energy conversion is greatly reduced due to reflections from the surface of the photovoltaic system. Also due to the peculiarities of the construction of photovoltaic converters there is a decrease in the efficiency of solar panels with increasing temperature.
