Ship power management system

Abstract

The invention discloses a ship power management system which comprises a group of generator systems and a controller, wherein the generator systems are mutually connected by a bus; the controller is connected to the group of generator systems; each generator system comprises a generator, a speed regulating device, a synchronous relay and an acquisition synchronizing module; the speed regulating device and the synchronous relay are connected to the generator; the acquisition synchronizing module outputs a load distributing signal and a split signal to the speed regulating device; the acquisition synchronizing module outputs a synchronous signal to the synchronous relay; the acquisition synchronizing module acquires load information and generator running parameters of the generator system; the controller judges whether a high-power load request exists or not on the basis of the load information detected by the acquisition synchronizing module in each generator system; the high-power load request is a load request exceeding generator system rated maximum load Pe; and when detecting the existence of the high-power load request, the controllers respectively process the high-power load request according to different conditions.

Description

technical field [0001] The present invention relates to marine electronic equipment, in particular to a marine power management system. On the one hand, the system adopts integrated components to replace original scattered components, and on the other hand, it can perform power distribution and power management according to power load. Background technique [0002] With the development of the world economy, the ocean transportation industry, which is the link of the world economic development, is also developing rapidly, followed by the prosperity of the shipbuilding industry. As an important system in the use of ships, the ship power management system has always been the focus of customers' attention on its operability, stability and maintenance convenience. In the past, the ship power management system was composed of various independent parameter acquisition components plus independent synchronous relays and PLCs. The components were relatively scattered, and the number w...

AI Technical Summary

Problems solved by technology

In the past, the ship power management system was composed of various independent parameter acquisition components plus an independent synchronous relay and PLC. The components were relatively scattered, and the number was large. There were many internal connections in the system, the failure rate was high, and the maintenance was not very convenient.

[0003] In addition, the existing ship power management system does not have the function of monitoring and distributing load power. When encountering a large power load request, the processing efficiency is low, and sometimes it cannot respond in time, which makes the power load too large, and sometimes cannot provide corresponding high power load
