电力机车低电压下的库内牵车功能实现

Realization of traction function in the depot of electric locomotive under low voltage

为解决低电压下大功率机车库内牵车功能不稳定、适用性差的问题,本文提出一种基于低电压下的电机特性拟合以及目标转差动态设定方案,实现了大功率机车在小容量库内电源供电条件下的库内牵引移动功能。试验表明,该方法移车效果平稳,适用于多轴重联下的长编组机车。

In order to solve the problems of unstable function and poor applicability of towing vehicles in high-power garages under low voltage, a scheme based on motor characteristic fitting under low voltage and dynamic setting of target slip is proposed to realize the traction and movement function of high-power locomotives in the warehouse under the condition of power supply in small-capacity warehouses. Test results show that the method is stable and suitable for long-series locomotives under multi-axle reconnection.
