Application Analysis of DC Negative 48V Photovoltaic Stack Power Supply System in Telecommunication Build-ing
In 2022,China Telecom proposed the"1248"Double Carbon action plan,which aims to re-duce corporate carbon emissions and promote the realization of the"Double Carbon"goal.In this pro-cess,the proportion and growth rate of green electricity use will increase It is the inevitable path to achieve the"Double Carbon"goal,and green electricity replacing fossil energy is also the main devel-opment trend in the future.At present,green power mainly includes wind power and photovoltaic power generation.The main ways to obtain green power are green power trading and distributed photovoltaic power generation for spontaneous self-use.Currently,photovoltaic power generation is extensively employed across various telecommunication stations.Based on the characteristics of the telecommuni-cation station power supply system,a more flexible and efficient DC photovoltaic stack power supply system is introduced,focusing on its system composition,structure and characteristics,and combined with typical application scenarios.The economic benefits and energy saving and emission reduction ef-fects are analyzed.
