Problems solved by technology

[0002] The ship shore power system simply means that when the ship is docked at the dock, it stops using the self-provided auxiliary generator on the ship and uses land power to supply power to the main shipboard system. However, the equipment of the current shore power decentralized power supply system occupies an area of Many, affecting the normal business of the terminal, high failure rate, high maintenance costs, high manufacturing costs, large cable usage, and difficult centralized control, thus bringing more inconvenience to the actual power supply process

Abstract

The invention provides a centralized ship shore power supply system, and the system comprises a first frequency conversion power module group, a second frequency conversion power module group, a firststep-down module group, and a second step-down module group. The first buck module group comprises a first step-down module and a second step-down module, and the second step-down module group comprises a plurality of third step-down modules. The first frequency conversion power module group is electrically connected with the first step-down module and the second step-down module. The second frequency conversion power module group is electrically connected with the third step-down modules. The first, second and third step-down modules are respectively connected with a high-voltage socket endand a copper bar junction box. The system provided by the invention saves the space resources of a harbor, simplifies a power supply network, saves the equipment cost and construction cost of a project, reduces more hardware equipment, improves the subsequent maintenance efficiency, and is high in practicality and economic benefits.

Description

Technical field: [0001] The invention relates to a centralized ship shore power supply system and relates to the field of ship shore power supply. Background technique: [0002] The ship shore power system simply means that when the ship is docked at the dock, it stops using the self-provided auxiliary generator on the ship and uses land power to supply power to the main shipboard system. However, the equipment of the current shore power decentralized power supply system occupies an area of Many, affect the normal business of the terminal, high failure rate, high maintenance costs, high manufacturing costs, large cable usage, difficult to centralized control, thus bringing more inconvenience to the actual power supply process. Invention content: [0003] The technical problem to be solved by the present invention is to provide a centralized ship shore power supply system that saves costs, is convenient to use and effectively improves power supply efficiency. [0004] In o...
