摘要： The present invention discloses a double-power energy saving system of rubber tire gantry crane (RTG), which is composed of a controller, a battery pack, a generator set and so on. The system changed the power supply mode of traditional RTG which is powered by a single generator set or a superposition of a generator set and a battery pack. Both the battery pack and the generator set of the system can support the RTG operations independently, forming the double-power energy saving system to improve the equipment reliability. The battery pack is used as the primary power source for RTG and the output power can be highly matched with the demanded power, which reduces the reactive loss and increases the energy efficiency. The generator set is shut down and the power is supplied by the battery pack when the electricity of the battery pack is high; the generator set is started to supply power directly for RTG when the electricity of the battery pack is low, and the surplus energy can charge the battery pack. Once the battery pack is put into operation, it will run in the best economical fuel consumption area to achieve the highest fuel efficiency. The feedback energy of RTG can be fully recovered because the charging power of the battery pack is larger than the maximum feedback energy power of RTG. It is not required to replace the original generator set of RTG when the system is applied to RTG transformations.

摘要： Disclosed is an extended-range full-electric low-speed tractor, which includes a system control unit, a battery pack, a frequency conversion driver, a bidirectional DC-DC converter, a generating set and a drive system. The generating set is capable of working in an intermittent mode. The generating set will be started when the power of the battery pack is lower than a preset working range; once the generating set begins to work, the generating set will be running under a condition of “the most economic fuel consumption” and provide stable output at constant speed and constant power, so as to make sure that the generating set is not overloaded, emits no black smoke and has highest energy efficiency. It has advantages of low energy consumption, low pollution and long life of the generating set.

摘要翻译： 本发明公开了一种由控制器，电池组，发电机组等组成的橡胶轮胎龙门起重机（RTG）的双功率节能系统。 该系统改变了由单个发电机组或发电机组和电池组叠加的传统RTG的供电模式。 系统的电池组和发电机组都可以独立支持RTG操作，形成双功率节能系统，提高设备可靠性电池组用作RTG的主要电源，输出功率可高 与需求功率相匹配，从而降低了无功损耗并提高了能源效率。 当电池组的电量高时，发电机组关闭，电池组供电; 当电池组的电量低时，发电机组开始直接为RTG供电，剩余能量可以对电池组充电。 一旦电池组投入运行，它将运行在最经济的燃油消耗区域，以达到最高的燃油效率。 由于电池组的充电功率大于RTG的最大反馈能量，RTG的反馈能量可以完全恢复。 当系统应用于RTG转换时，不需要更换RTG的原始发生器组。
