摘　　要：发展先进适用的节支技术是实现电气化铁路节支的重要途径。为进一步降低支线铁路基本电费支出,对最大需量控制技术开展研究。依据线路行车组织及现场实测数据,分析支线铁路最大需量特点,提出一种由需量管理装置和有功融通装置构成的最大需量控制系统。阐述基于变电所间有功融通的最大需量控制原理,制定计及牵引负荷有功功率、系统额定功率和预设融通阈值等多项约束条件的控制策略,并通过算例分析证明该控制策略的正确性和有效性。研究结果表明,支线铁路相邻变电所的牵引负荷错峰出现,适宜通过变电所间有功双向融通进行最大需量控制,节支效果良好。Developing advanced and applicable technology is an important way to save cost of electrified railways. The maximum demand control technology is studied to further reduce the basic electricity expense of branch railway lines. According to the train operation organization and field measured data, this paper analyses the maximum demand characteristics of branch railway lines, and proposes a maximum demand control system consisting of demand management device and active power transfer facility. Meanwhile, the paper describes the maximum demand control principle based on active power transfer facility between substations, formulates a control strategy considering multiple constraints such as active power of traction load, rated power of system and preset transfer threshold, and demonstrates the correctness and effectiveness of the control strategy through arithmetic analysis. The results show that the traction load of adjacent substations of branch railway lines occurs in staggered time slots. Therefore, it is appropriate to carry out maximum demand control through active two-way transfer between substations, and the cost-saving effect is good.
