摘要
对应绿色建筑"安全""宜居""生态可持续"的三项核心要求,分别从设备安全和人身安全、可靠性与用户体验及电能质量、新能源消纳及降低损耗的角度分析了低压直流配电在建筑中的应用优势。并就低压直流配电的电压等级、接地方式、保护监控和协调控制等实际问题进行了具体论述,提出了系统实际设计及运行过程中所应考虑的问题并给出相应的建议。从标准、性价比、负荷三方面分析了目前低压直流配电在实践中面临的问题及相应的对策,指出今后建筑配电直流化发展的必然性。
In response to the three core requirements of safety,livability and ecological sustainability of green buildings,the application advantages of LVDC(short for low-voltage DC)power distribution in buildings are analyzed from the aspects of equipment safety and personal safety,reliability and user experience,power quality,new energy consumption and loss reduction.The practical problems such as voltage level,grounding mode,protection monitoring and coordination control of LVDC distribution are discussed in detail.The problems that should be considered in the actual design and operation of the system are proposed and corresponding suggestions are given.From the problems analysis of the standard,costeffective,and DC loads of the current LVDC distribution in practice,the corresponding countermeasures are expounded,and the inevitability of future development of DC building is pointed out.
