Recently, the ship shore power system, which was developed by State Grid Jiangsu Power Company and contains a complete set of equipment and solutions, passed the acceptance test. This is also the first domestic complete set of ship shore power systems including high pressure and low pressure.

It is reported that the difficulty of shore power technology lies in high-voltage frequency conversion and grid connection at the same time. Most of the products produced by domestic manufacturers are low-voltage shore power, which is equivalent to low-voltage AC charging piles, no grid-connected devices, low technical content, and cannot provide uninterrupted power supply. . The cost of high-voltage frequency conversion technology is far greater than that of low-voltage shore power, and the technical difficulty is also large.

     Compared with similar products, the system has a complete set of equipment and solutions such as high-voltage shore power frequency conversion power supply, low-voltage shore power supply, and inland river terminal small-capacity shore power supply, which can meet the needs of providing shore power for various types of ports in China. The director of the company has the advantages of high level of complete set, comprehensive program, advanced technology, complete functions and great market prospects, especially in terms of comprehensiveness of the program, technological leadership and exquisite craftsmanship. In terms of technology, the system has high power quality, stable frequency regulation, high output power factor, good waveform quality, and output harmonic current of no more than 1% , which is superior to national standards.

The high degree of intelligence is a highlight of the shore power system. The shore power supply developed by the company's shore power system can be automatically synchronized to the ship's power supply to complete the grid connection, realize the load transfer, meet the requirements of the ship's uninterrupted power supply, and only need to pass the cable connection between the ship power and the shore power. The network control box, one-click to complete the shore power supply to the ship. At present, the automatic grid-connected technology has been declared a national invention patent.
