Embodiment Construction
[0049] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0050] The main design principle of the present invention is to use a diesel generator set as the energy supply source of the energy storage unit to perform low-power power generation (or directly use a low-power diesel generator set) to charge the energy storage unit for a long time, while the energy storage As the main power supply, the unit provides effective power supply for the high-power operation of the operating mechanism.
[0051] see figure 1As shown, the power supply system 100 for ship operation of the present invention includes a diesel generator set 110 as a power supply source, an AC / DC converter 120, an energy storage unit 130 and a DC / DC converter 140 as a power supply source for the operating mechanism 1, The diesel generator set 110 includes a diesel engine 111 and a generator 112, which generate low-power ...

Abstract
The invention provides a power supply system of shipping work, which supplies small power electric energy by using a diesel engine electric generating set as an electric energy supply source and meets high power energy requirement for operation of a work mechanism by using an energy accumulating unit as a power supply source of the work mechanism. The invention also provides a power supply method of the shipping work. By adopting the power supply system and the method of the invention, compared with the traditional power supply scheme, the invention can save the fuel by over 40-60 percent, thereby the power and the oil consumption of the diesel engine unit are obviously reduced, and emission pollution is greatly reduced to achieve the aim of saving energy and reducing emission.
Description
technical field [0001] The invention relates to energy supply technology for ship operations, and more specifically, to a power supply system and method for ship operations. Background technique [0002] Operation ships are widely used in many fields such as port construction, waterway regulation, underwater construction, mineral mining, submarine umbilical laying, danger prevention and rescue, ocean development, ocean utilization, fishery production, etc. Except that the overall performance of some operating ships is similar to that of transport ships, they generally have unique characteristics. For example, piling ships, carrying and unloading ships, crane ships, salvage ships, pipe-laying ships, cable-laying ships, etc. for water engineering operations; tugboats, dredging ships, dredgers, sand suction ships for port channel operations Etc.; Drilling ships, excavation ships, etc. for marine development; Fishing ships for fishing, etc. see figure 1 As shown, the operatio...
