Method for assisting ship berthing at port to use shore power

Abstract

The invention discloses a method for assisting a ship berthing at a port to use shore power. Historical information about that the ship is connected with shore power is shared through information interaction between a ship shore power data center and a port shore power data center, the berthing direction of the ship is guided and a ship user is guided to select appropriate shore power capacity byautomatically searching historical berthing information of the ship before the ship berths at the port; in the inspection work before ship-shore connection, an operator can be clearly indicated to test a safety circuit, the uncertain problems caused by non-unified design standards of safety circuits, un-real-time updating of late transformation information and the like are avoided, and the serviceefficiency of port shore power is improved. A port side performs data processing by referencing the historical information of the berthed ship and adopting a weighting coefficient method and configures the appropriate shore power capacity, excessive configuration is avoided, and the investment cost is reduced.

Description

technical field [0001] The invention relates to an auxiliary method for using shore power for ships berthing at a port, and belongs to the technical field of power system operation control and informationization. Background technique [0002] At present, the state is vigorously promoting the construction of shore-based power supply in ports, requiring important ports to build shore-based power supply for docking ships, reducing fuel pollution emissions from ships, encouraging ports to use shore power, and improving the level of green development. However, the actual application effect of port shore power is not ideal at present. It is caused by many reasons, most of which are due to improper technical methods that cause the ship-shore connection time to be too long and inconvenient to use, which affects the enthusiasm of the ship owner. The enthusiasm of the ship owner is not high, and the port party The return on investment in building shore power will be affected. [0003...

AI Technical Summary

Problems solved by technology

However, the actual application effect of port shore power is not ideal at present. It is caused by many reasons, most of which are due to improper technical methods that cause the ship-shore connection time to be too long and inconvenient to use, which affects the enthusiasm of the ship owner. The enthusiasm of the ship owner is not high, and the port party The return on investment in building shore power will be affected

[0003] At present, the standards for shore-based power supply systems for ships are not uniform. Different ships will have different problems when using shore power at the same berth. Since the port and starboard sides of the ship are two different power systems, the wrong direction of docking will not only cause the ship to shore The detection test before electrical connection cannot be carried out, which will bring unnecessary troubles, and the ship’s reorientation will greatly increase the energy consumption and docking time of the ship. It is urgent to study a correct docking method to guide ships coming to the port to use shore power.

[0004] In addition, not only are the standards of the ship’s shore-based power supply system not uniform, but many ships that receive shore-based power supply are rebuilt at a later stage, and the ship does not update the refit information in real time, resulting in the failure to confirm the safety circuit of the safety circuit test before connecting to the shore power supply.

The safety circuit detection test cannot be carried out or it will take a long time to verify that the safety circuit is normal, which has a great impact on the efficiency of shore power connection

The existing standards put forward requirements for the detection link of the safety circuit, but there are few studies on the safety circuit test instructions before connecting to the shore power, that is, from the perspective of convenient use, there is a lack of research in this area

[0005] Finally, the cost of shore power investment by the port side is relatively high, and recovery is difficult. The current conventional design method is based on the "JTS 155-2012 Technical Specifications for the Construction of Ship Shore Power Facilities at Wharf", that is, it is designed according to the maximum power of the single auxiliary engine of the ship. According to the actual situation of multiple shore power connections by the port side, the design capacity of the shore power supply is too large, but there are few studies on the allocation basis and methods for taking appropriate measures to effectively reduce the port shore power, that is, from the perspective of the investment and construction party However, there is a lack of cost-effective solutions for the layout of shore power at ports.
