悬挂式单轨车辆再生能量特性研究

悬挂式单轨工程由于车辆不设置车载电阻,其制动时产生的再生能量依靠设置于变电所的再生能量吸收装置吸收。目前国内悬挂式单轨工程供电系统再生能量吸收装置的设计方案,大多照搬地铁或有轨电车惯用做法,并未对该制式的再生能量特性进行细化研究。文章以国内某城市实际工程为研究对象,建立单列车和不同行车密度运行时仿真模型,研究各牵引变电所再生能量吸收装置吸收峰值功率、能量值、吸收范围和吸收趋势,总结悬挂式单轨车辆再生能量特性,研究结论对悬挂式单轨工程再生能量吸收装置的选型及布置方案设计有一定的借鉴和指导意义。

Study on regenerative energy characteristics of suspended monorail engineering vehicle

The regenerative energy generated during braking of suspended monorail engineering vehicle depends on the regenerative energy absorption device set in the substation because of no on-board resistance.At present,most of the design schemes of the regenerative energy receiving and absorption device of the power supply system of the suspended monorail project in China copy the common practice of the subway or tram,and have not carried out detailed research on the characteristics of the regenerative energy of the system.This paper takes a real project of a city in China as the study case,establishes the simulation model of single train and operation with different traffic density,studies the absorption peak power,energy value,absorption range and absorption trend of the regenerative energy absorption device of each traction substation,summarizes the regenerative energy characteristics of the suspended monorail vehicle,and concludes the selection and distribution of the regenerative energy absorption device of the suspended monorail project.The scheme design provides certain reference and guidance signifi cance.
