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.
