Vehicle-passenger ferry provided with energy storage unit type hybrid electric propelling system

Abstract

The invention relates to a vehicle-passenger ferry provided with an energy storage unit type hybrid electric propelling system. The vehicle-passenger ferry comprises a ferry body, wherein power generation components, energy storage components, power distribution and supply components, propelling components, propeller components and control and management components are arranged on the ferry body; the power generation components and the energy storage components are connected with the power distribution and supply components, the power distribution and supply components are connected with the propelling components and the propeller components, the propelling components are connected with the propeller components, and the power generation components, the energy storage components, the power distribution and supply components, the propelling components and the propeller components are connected with the control and management components; diesel power generation components and shore power access components are connected with a ferry electric power system through change-over switches. The energy saving benefits can be further improved through the energy storage components, meanwhile, the problem about time difference of increasing of the power of a power station and increasing of the propelling power is solved, the power supply reliability of a power grid is further improved, energy consumption and the cost are further reduced, and the energy-saving and environment-friendly effects are improved.

Description

technical field [0001] The invention belongs to the technical field of ships, in particular to a car-passenger ferry with an energy storage unit hybrid electric propulsion system. Background technique [0002] As the first full-turn car ferry with counter-rotating propellers began to operate, the advanced full-turn rudder propeller replaced the conventional propulsion method of four propellers and eight rudders, which greatly improved the safety and operating economic benefits of car-passenger ferry transportation. In recent years, the design and equipment manufacturing level of car-passenger ferries has been continuously improved, but the propulsion method still adopts the form of diesel engine mechanical propulsion. At present, some new propulsion methods, such as electric propulsion, have begun to be popularized and used on inland waterway ships with the gradual maturity of related technologies. This is also in line with the current general trend of diversifying ship prop...

AI Technical Summary

Problems solved by technology

The existing relatively advanced vehicle-passenger ferry propulsion method basically adopts the form of a Z (L) rudder propeller driven by a diesel engine with an extended shaft system. Arrangement at a certain angle requires multiple sets of intermediate bearings and universal couplings. Therefore, there are many problems such as high requirements for machine location layout, large space occupation, large transmission loss, and large working noise and vibration.
