Intelligent ship shore-based power supply device

Abstract

The invention discloses an intelligent ship shore-based power supply device. The power supply device is composed of a transformer and input connecting part, a power part, a control system, an output connecting part, a debugging system, a small control screen and a superior interface. The transformer and input connecting part is connected with the power part through a power line. The power part is connected with the output connecting part through a power line and connected with the control system through optical fibers. The small control screen and the debugging system are connected with the control system through RS232 interfaces. The superior interface is connected with the control system through an RS485 interface. According to the power supply device, the power part is composed of IGBTs, and a DSP chip is used as a control core. By means of the power supply device, the frequency of a power source can be automatically adjusted, ship power sources can be switched without interference, the state of the power supply device and the states of ship power utilization devices can be automatically monitored, and power management can be intelligently carried out.

Description

technical field [0001] The invention belongs to the field of shore-based power supply facilities, and relates to intelligent ship shore-based power supply equipment. Background technique [0002] At present, most domestic ships use their own generators to provide power when they are in port, which will have a great impact on the port environment and is not conducive to energy conservation and emission reduction. The use of shore-based power supply during the ship's berthing can effectively reduce environmental pollution. However, due to the inconsistency between the frequency of foreign ship power and domestic power supply, the grid power supply needs to undergo frequency conversion to meet the needs of ships, resulting in slow development of shore-based power supply equipment. Moreover, the existing shore-based power supply equipment has problems such as complicated operation, simple function, and imperfect protection. Contents of the invention [0003] In order to overc...

[0002] At present, most domestic ships use their own generators to provide power when they are in port, which will have a great impact on the port environment and is not conducive to energy saving and emission reduction.

The use of shore-based power supply during the ship's berthing can effectively reduce environmental pollution. However, due to the inconsistency between the frequency of foreign ship power and domestic power supply, the grid power supply needs to undergo frequency conversion to meet the needs of ships, resulting in slow development of shore-based power supply equipment. Moreover, the existing shore-based power supply equipment has problems such as complex operation, simple function, and imperfect protection.
