城轨交流牵引变电所容量设计方法研究

为解决直流制式带来的迷流腐蚀和交流制式下难以突破的电分相问题,对城市轨道交通交流牵引供电技术做进一步的理论计算和仿真研究,根据实际应用中对城市轨道交通牵引供电系统的要求提出系统设计原则;基于电流分配定理和压损计算方法研究牵引变电所和系统变电所的位置和数量设计,并计算其安装容量;基于某实际线路情况设计其交流牵引供电方案,并对牵引变电所和系统变电所进行容量设计及仿真验证。

In order to solve the stray current corrosion caused by the DC system and the most difficult problem of electrical phase separation under the AC system,further theoretical calculations and simulation studies have been made on the AC traction power supply technology of urban rail transit.The system design principles are put forward according to the requirements traction power supply system of urban rail transit in practical applications;the location and quantity design of traction substations and system substations are studied based on current distribution theorem and voltage loss calculation method,and their installation capacity is calculated.The capacity design and simulation verification of the traction substation and system substation has been made on the basis of AC traction power supply scheme of a railway line in accordance with the its actual conditions.
