摘要
介绍了牵引供电系统电压损失准确计算方法和工程近似方法,并针对交直型机车和交直交型机车的不同负荷特性对其在牵引供电系统中产生的电压损失进行了计算和分析,指出采用工程近似方法计算交直交型机车在牵引供电系统中产生的电压损失存在较大误差,分析了误差产生原因,并提出建议解决措施。
The accurate method and approximate method for calculating voltage loss of traction power supply system are introduced in this paper.The voltage losses of traction power supply system for AC/DC locomotive and AC/DC/AC locomotive are calculated and analyzed respectively.It is pointed out that there is great error with the voltage losses for AC/DC/AC locomotive using the approximate method.The reasons of error are illustrated and measures to decrease error are proposed.
