摘要
为了解决数据中心、分布式电源以及直流用电负荷不断接入的问题,对智能楼宇的直流供电系统实施方案进行研究。首先,针对智能楼宇高可靠性的供电需求,设计了闭环双层环状直流配电网拓扑结构;然后,制定了适用于直流配电的系统保护方案,并对主要保护设备进行优化选型;最后,考虑投资成本和传输效率,分析了直流配电方式的经济性。结果表明,所提出的直流配电系统实施方案可降低损耗、提高经济效益,能够满足智能楼宇的用电需求。
In order to solve the access problem of data center, distribution power supply and DC electrical power load, the paper studies on the DC power supply system of intelligent building. Firstly, according to the requirements of power supply intelligent buildings, the paper presents the double ring closed-loop DC distribution system architecture. Then, the protection configuration scheme of the system architecture is formulated, and the main protection equipment optimization selection is achieved. Finally, considering of the cost of investment and transmission efficiency, the economic efficiency of DC power distribution mode analyzed. The result shows that the proposed implementation of the DC power distribution can reduces the loss, improve the economic benefits and meet the demand of the intelligent building
