摘　　要：复杂艰险山区修建高标准铁路的需求日益紧迫。这些铁路技术标准高、长大坡道多、列车再生制动功率大。当再生制动能量反送回电网时将引起牵引网电压高,易引起列车车顶间隙放电、导致列车制动失效,严重时将影响铁路的正常运行。以国内某典型牵引变电所负荷数据为例,定量评估了长大坡区段的列车日再生制动能量特性,分析再生制动功率引起的牵引网电压抬升情况;然后建立相应的仿真模型,并利用实测数据进行验证;基于所建仿真模型,模拟分析客货列车在不同制动条件下进行再生制动时对牵引网电压抬升的影响;最后研究了抑制再生制动对牵引网电压抬升的工程措施。The demand of railway construction in complex and dangerous mountain areas is becoming increasingly urgent.These railways have high technical standards,long ramps and high regenerative braking power.When regenerative braking energy is fed back to the grid,it will cause the voltage of the traction network to rise.The increased voltage is likely to cause gap discharge of the train roof and failure of train braking,which will affect the normal operation of the railway.Based on this,this paper takes the load data of a typical traction substation in China as an example,quantitatively evaluates the characteristics of daily regenerative braking energy of load in the long slope section,and analyzes the voltage rise of traction network at the moment of maximum daily regenerative braking power.Then the corresponding simulation model is established and verified by the measured data.Based on the established simulation model,the influence of passenger and freight trains on the traction network voltage during regenerative braking under different braking conditions is simulated and analyzed.Finally,measures to restrain the rising of traction network voltage caused by regenerative braking are studied.
