Description

Technical Field

[0001] The invention belongs to the technical field of ship engineering, and in particular relates to an electrical transformation method for an engineering ship. Background Art

[0002] The "Chuanchuan Changjiang 001" ship is the largest "oil-to-electricity" bulk carrier in the country's inland river deadweight tonnage, marking a new stage in the domestic inland river ship "electricity instead of oil" energy revolution. Its successful transformation and delivery not only reflects the application and development of technology in the field of green ships, but also plays a good demonstration effect for the market application of new energy ships.

[0003] The successful sea trial of Sichuan Yangtze River 001 has made it the first cargo ship in the province to pilot the "oil-to-electricity" project. It is also the first 3,000-ton "oil-to-electricity" ordinary cargo ship in the country's inland rivers. This achievement has broken the record for the largest tonnage of existing inland "oil-to-electricity" project ships.

[0004] The ship uses advanced lithium iron phosphate battery system, integration and centralized control system, which greatly improves the digitalization level of the ship and demonstrates the technological progress and application prospects of green and intelligent ships.

[0005] The distributed photovoltaic power generation project adopted by Chuanchuan Yangtze River 001 has reduced the port operation costs, reduced carbon emissions, and demonstrated Xuancheng Water Transport’s firm belief in the path of green development.

[0006] As we all know, fossil energy such as oil and coal are non-renewable resources. Under the current international background, crude oil reserves are gradually decreasing. Once oil resources are exhausted, internal combustion engines will completely withdraw from the stage of history. In addition, as the standards set by the International Maritime Organization on ship emissions become more and more stringent, green and environmentally friendly electrified engineering ships will become the future development direction. Therefore, a method for electrification transformation of engineering ships is proposed. Summary of the invention

[0007] The purpose of the present invention is to provide an electrification transformation plan for engineering ships to solve the dependence of engineering ships on oil and reduce harmful gas emissions and noise pollution.

[0016] The DC main switchboard is equipped with an energy management system to centrally manage and distribute the ship's electrical energy, monitor the status of all battery packs, and send relevant data of the battery cabinet and battery pack to the intelligent wireless monitoring control cabinet through the charging and discharging interface.

[0017] In one embodiment, in step S2, a set of DC distribution boards is added at an appropriate position of the original engineering vessel to receive the electric energy transmitted by the power supply pontoon; the DC distribution board has the ability to connect two pontoons at the same time;

[0018] After the original engineering ship diesel engine, generator and its accessories are dismantled, the base of an electric motor with the same power is welded at the original diesel engine position so that the motor can be installed smoothly and correctly; and a drive cabinet is added at the appropriate position of the engineering ship; the motor driver is installed in the drive cabinet; the motor driver is connected to the DC distribution board and the motor respectively through cables; a GPRS module is installed in the DC distribution board to realize remote monitoring of the engineering ship's data.

[0019] In one embodiment, in step S3, the electrification transformation is as follows:

[0020] S31, add frequency converter;
