Abstract：In light of the significant power consumption with the integrated transportation hub and the high proportion of Class I and Class II load,the rationality of power supply and distribution scheme directly affects the reliability of power supply and the convenience for emergency dispatching,as well as the characteristics of construction investment at the initial phase，based on the available load data of some practical engineering cases,this paper analyzes and investigates the merits and demerits of the conventional power supply and distribution system design scheme that introduces 4-way 10kV power supply and sets 2 switching stations. In view of the gaps with the conventional design scheme,this paper proposes the load transfer technical scheme with three‑way power supply and four buses.

摘　要：结合综合交通枢纽用电量大，一、二级负荷占比高，供配电方案的合理性直接影响供电的可靠性、紧急调度方便性，同时影响初期建设投资的特点，以实际工程案例负荷资料为基础，对传统供配电系统设计方案中外引4路10 kV电源、设置2个开闭所方案优缺点进行分析研究。针对传统设计方案存在的不足，提出三电源四母线的负荷转移技术方案。
