Ship region distribution system and monitoring system thereof

Abstract

The invention designs a comprehensive ship power supply system and a monitoring system thereof by organically combining an annular power supply network and a regional distribution technology. Two power buses of the power system penetrate through two boards of a ship and are connected with two generator sets on the head part and the tail part of the ship so as to form an annular grid. The annular grid of the entire ship is divided into a plurality of regions according to load properties and load volumes, and each generator set ensures load power supply in one or more regions. At inlets of the regions, the buses of the annular grid are provided with a plurality of disconnectors. The monitoring system comprises a first layer of bus nodes on the regions, a second layer of region control stations and a third layer of system network, wherein a central computer and the region stations are connected with one another by an industrial Ethernet. According to the invention, a ship power system, a power propulsion system, a communication system and the like are integrated into an intelligent system so as to realize information sharing, uniform energy regulation and control, and coordination action of the system devices.

Description

technical field [0001] The invention belongs to the field of ship engineering, and relates to a design method of a ship regional power distribution system and a monitoring system thereof. Background technique [0002] With the introduction of the concept of ship integrated power system (IPS), the urgent need for the application of the whole ship power system and electric propulsion technology to ships, the system capacity of the ship power system will rise in a geometric curve, so that the cable layout becomes a prominent issue: First, the form of the traditional ship power grid has become a major problem restricting the reliability of the ship. When the ship is damaged, the ship power grid is prone to collapse, affecting the quality of power supply and low vitality; or when a large load in the ship starts or fails , will also affect the power supply quality of the grid. In short, the traditional ship power grid can no longer meet the requirements of future ships; second, t...

[0002] With the introduction of the concept of ship integrated power system (IPS), the urgent need for the application of the whole ship power system and electric propulsion technology to ships, the system capacity of the ship power system will rise in a geometric curve, so that the cable layout becomes a prominent issue: First, the form of the traditional ship power grid has become a major problem restricting the reliability of the ship. When the ship is damaged, the ship power grid is prone to collapse, affecting the quality of power supply and low vitality; or when a large load in the ship starts or fails , will also affect the power supply quality of the grid

With the increasing scale of modern ships and the use of new power systems, the original ship power monitoring system can no longer play its role
