If the ships docked at the port wharf can turn off the diesel generators and switch to the port power grid for power supply, it can not only reduce air and water pollution, but also reduce the operating costs of the ships
However, the electrical system on most ships is different from that of the port. At this time, it is necessary to supply power to the ship through the shore power converter. Inomax ACS880 shore power inverter is powered by the shore side AC grid or alternator, and can output reliable high-quality three-phase AC power with a frequency that meets the requirements of the ship.
ACS880 shore power converter consists of a shore rectifier and a ship-side power inverter. The shore rectifier has two kinds: diode rectifier and IGBT active rectifier. The ship-side power inverter is composed of IGBT power module combined with ABB’s unique DTC control technology and LCL filter.
The shore power converter adopts multiple power modules of the same size in parallel. The power module is a plug-in trolley structure, which is convenient for maintenance. When a module is faulty, you can quickly replace the faulty module or remove the faulty module. The remaining intact modules continue to run in reduced capacity, providing excellent redundancy.
Advantages of Products
