摘要
2022年中国电信提出“1248”双碳行动计划,目的是减少企业碳排放量,推动“双碳”目标的实现,而在此过程中,绿电使用占比和增速提升是达到“双碳”目标的必然路径,且绿电替代化石能源也是未来主要的发展趋势。现阶段绿电主要包括风电和光伏发电,获得绿电的途径主要有绿电交易和分布式光伏发电自发自用。目前光伏发电在各类通信局站已广泛应用,结合通信局站供电系统自身特点,对一种更加灵活高效的直流叠光供电系统进行了介绍,重点阐述其系统组成、结构及特点,并结合典型应用场景对经济效益及节能减排效果进行了分析。
In 2022,China Telecom proposed the"1248"Double Carbon action plan,which aims to reduce corporate carbon emissions and promote the realization of the"Double Carbon"goal.In this process,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 development 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 effects are analyzed.
