The invention relates to the technical field of shunting control, in particular to a hybrid power supply control method suitable for a low-speed shunting locomotive, which comprises the following steps of: setting a preset level I and a preset level II of a power battery; when the handle level is smaller than or equal to the first preset level, the diesel engine is not started, and the power battery supplies power; when the handle level is larger than the first preset level and smaller than or equal to the second preset level, the maximum discharge power and the maximum discharge time of the bidirectional DC-DC are calculated according to the current locomotive temperature, and whether the diesel engine is started or not is determined; when the handle level is larger than the preset level II, the diesel engine is started, and the diesel engine and the power battery supply power in a hybrid mode. According to the hybrid power supply control method suitable for the low-speed shunting locomotive, if the working condition of the locomotive can be met at the preset level II, the situation that the diesel engine is started when the working condition is greater than the preset level I in the prior art can be avoided, so that the starting frequency of the diesel engine is reduced, and the service life of the diesel engine is ensured.
本发明涉及调车控制技术领域,具体涉及一种适用于低速调车机车的混合供电控制方法,包括如下步骤:设定动力电池的预设级位一和预设级位二;当手柄级位小于或等于预设级位一时,不启动柴油机,动力电池供电;当手柄级位大于预设级位一且小于或等于预设级位二时,根据当前机车温度计算双向DC‑DC的最大放电功率和最大放电时间决定是否启动柴油机;当手柄级位大于预设级位二时,启动柴油机,柴油机和动力电池混合供电。本发明提供的适用于低速调车机车的混合供电控制方法,如果在预设级位二就能满足机车作业工况,就可以避免如现有技术中大于预设级位一时即开启柴油机,从而减少了柴油机的启动次数,保证了柴油机的使用寿命。
