摘要
以某研发办公大楼项目设计为例,分析了民用建筑低压直流配电不同电压的供电半径,确定了低压直流电压等级;对比了单极、双极母线架构的优缺点,选择了适合项目规模的双极母线架构;讨论了数据中心不同高压直流供电架构的效率与可靠性,并介绍了一种结合光伏发电的市电+光伏高压直流双路电源的数据中心供电方案。提出建筑内的储能蓄电池与传统UPS蓄电池不同,应主要关注蓄电池的循环寿命和消防安全性能,阐述了水系锌离子电池储能方案及直流充电桩配置选择,并给出了项目直流配电系统经济模式的运行策略。
Based on an office building project design,the power supply radius of different voltages of low voltage DC(LVDC)distribution system is analyzed,and the low voltage DC voltage class is determined.By comparing the unipolar and bipolar bus architectures,the suitable bipolar bus is selected.The efficiency and reliability of different HVDC power supply architectures in data centers are discussed,and a scheme combining photovoltaic power generation with power grid+PV high voltage DC power supply is introduced.It is proposed that the energy storage batteries used in buildings should pay attention to the cycle life and fire safety performance of the batteries,which are different from the traditional UPS batteries.The energy storage scheme of zinc-ion battery in water system and the configuration choice of DC charging pile are described.The operation strategy of economic mode of DC power distribution system is given.
