The invention relates to the technical field of locomotive control, in particular to an electric-electric hybrid power locomotive energy distribution and conversion control method. The method comprises the steps that S10, whether the current mode of the locomotive is a shunting mode or a main track mode is judged, if the current mode is the shunting mode, the step S20 is executed, and if the current mode is the main track mode, the step S30 is executed; s20, judging whether the current speed of the locomotive is 0 or not, and when the current speed of the locomotive is 0, operating a pantograph lifting key-lifting switch to allow pantograph lifting of the locomotive; when the pantograph of the locomotive rises, the power battery system is automatically switched on to charge the power battery and provide energy required by the auxiliary system; when the locomotive pantograph rises, locomotive traction is blocked, and traction force output is prohibited; s30, judging whether the current locomotive pantograph rises or not; if the pantograph rises, when the locomotive has traction requirements, the energy obtained by the high-voltage system from the overhead line system preferentially provides traction power, and the residual energy charges the power battery.
本发明涉及机车控制技术领域,具体涉及电电混合动力机车能量分配与转换控制方法。该方法包括:S10、判断机车当前模式为调车模式或正线模式,若为调车模式则执行步骤S20,若为正线模式则步骤S30。S20、判断机车当前速度是否为0速,当机车为0速时,操作升弓扳键开关,允许机车升弓;当机车受电弓升起,动力电池系统自动投入,为动力电池充电,同时提供辅助系统所需能量;当机车受电弓升起后,机车牵引封锁,禁止输出牵引力;S30、判断当前机车受电弓是否升起;若受电弓升起,在机车有牵引需求,高压系统从接触网获取的能量优先提供牵引功率,剩余能量向动力电池充电。
