The invention provides a train positioning method based on electrical quantity. The method comprises the following steps: arranging a voltage sensor, a current sensor and an acquisition device on a feeder cabinet of each traction power supply station on a running line of a train; making a train run between two traction power supply stations provided with voltage sensors, current sensors and acquisition devices, the voltage sensor and the current sensor of the traction power supply station at one end are selected to measure voltage values and current values of contact networks at the two ends of a direct-current feeder cabinet respectively, and transmitting the voltage values and the current values to an upper computer; and establishing a train position calculation equation based on the voltage value and the current value of the line end at the single-side traction substation by the upper computer, and introducing the received voltage value and the current value into the train position calculation equation to calculate the position information of the train at a certain moment. According to the method, only the voltage and current values of the single-side traction substation feeder cabinet of the traction power supply line need to be measured, the method is simple, and a train positioning reference can be provided for commanding and dispatching personnel when a signal system breaks down.

    本发明提供了一种基于电气量的列车定位方法。包括:在列车的运行线路上的各牵引供电所的馈线柜设置电压传感器、电流传感器和采集装置;列车在两个设置了电压传感器、电流传感器及采集装置的牵引供电所之间运行,选取一端的牵引供电所处的电压传感器和电流传感器分别测量出直流馈线柜两端的接触网的电压值、电流值,并传输给上位机;上位机建立基于单侧牵引变电所处线端电压值、电流值的列车位置计算方程,将接收到的电压值和电流值代入到所述列车位置计算方程,计算得到某一时刻列车的位置信息。本发明方法仅需测量牵引供电线路单侧牵引变电所馈线柜的电压、电流值,方法简单,可以在信号系统出现故障的时候为指挥调度人员提供列车的定位参考。
