Problems solved by technology

[0003] 1. More waste gas and waste water are discharged, which cause serious environmental pollution
[0004] 2. The noise pollution is very serious, and the comfort of the riding environment is relatively low
[0005] 3. Large energy consumption and poor operating economy
[0008] On the other hand, for electric ships using AC transmission, since the motor power of the propulsion system is generally large, when starting and stopping and changing the driving power of the motor, the harmonic pollution to the AC power of the entire ship is serious
In addition, most of the electric boat loads are inductive load motors, so the power factor of AC power is very low, the efficiency of AC power transmission is low, and the reactive power loss is serious. In addition, the quality of power supply for other AC loads used in ships is also poor.

Embodiment 1

[0026] Such as figure 2 As shown, in this embodiment, the new energy power generation unit 10 is a combination of a solar power generation unit 11 and a wind power generation unit 12, which together provide electric energy for a new energy electric boat, wherein the solar power generation unit 11 can be an ordinary solar power generation device , a thin-film solar power generation device, and a concentrated solar power generation device or a combination thereof. In this embodiment, the solar power generation unit 11 adopts an ordinary crystalline silicon solar power generation device. The wind power generation unit 12 is one or a combination of a DC permanent magnet wind generator and a switched reluctance wind generator. In this embodiment, the wind power generation unit 12 adopts a DC permanent magnet wind generator. Due to the intermittent and unsustainable nature of wind and solar energy, combining them can complement each other. Such as figure 2 , the solar power gene...

Embodiment 2

[0032] The basic structure of the new energy electric ship of the present invention is the same as that of Embodiment 1, the difference is that, as image 3 As shown, the electric energy storage unit 20 is a combined electric energy storage unit composed of a battery energy storage device and a super capacitor energy storage device. The power of electric boat propulsion motors is generally large. Considering the characteristics of the motor, the starting current is generally several times the rated current, especially in the occasion of frequent start and stop, which has a great impact on the life of the battery. Supercapacitors have outstanding advantages such as strong resistance to high-current impact energy and long service life. The supercapacitor energy storage device is set in the electric energy storage unit, so that the large current at startup can be obtained more from the supercapacitor. When the energy of the supercapacitor is insufficient, it can be charged by the...

Embodiment 3

[0034] The basic structure of the new energy electric ship of the present invention is the same as that of Embodiment 1, the difference is that, as Figure 4 As shown, the electric energy storage unit 20 is a supercapacitor energy storage device, which is used in occasions where the cruising range is short and the charging and replenishment on the shore is convenient. Because the supercapacitor allows a large charging current, it charges quickly, which simplifies the system structure and reduces system maintenance costs. In this embodiment, the electric energy storage unit 20 is provided with a supercapacitor management device 23 , which may adopt a general supercapacitor management device (CMS).

Abstract

The invention relates to a novel energy electric ship. The novel energy electric ship comprises a novel energy power generating unit (10), an electric energy storage unit (20), a charging unit (30), an electric propulsion unit (40) and an electricity load as well as a master control unit (50). The electric propulsion unit (40) and the electricity load are direct current loads. Electricity generated by the novel energy power generating unit (10) is stored in the electric energy storage unit (20) through the charging unit (30). The electric energy storage unit (20) is connected with the electric propulsion unit (40) and the electricity load and directly conveys direct current to the electric propulsion unit (40) and the electricity load for providing an operational power supply. The novel energy electric ship provided by the invention can effectively reduce the energy consumption and improve the energy utilization rate, effectively enhance the continuation voyage course, and is free from pollution and low in noise.

Description

technical field [0001] The invention relates to an electric-driven ship, in particular to a new energy electric ship powered by electric energy generated by renewable energy sources such as solar energy, wind energy, and tidal energy. Background technique [0002] Ships are one of the most important means of transportation. As we all know, traditional ships are mainly driven by heat engines, such as diesel engines, steam turbines, and gas turbines. Notable flaws are as follows: [0003] 1. The discharge of waste gas and waste water is more, and the environmental pollution is more serious. [0004] 2. The noise pollution is very serious, and the comfort of the riding environment is relatively low. [0005] 3. The consumption of energy is large, and the operating economy is poor. Especially in recent years, due to the rapid rise of fuel oil prices, ship operators are under greater pressure on operating costs. [0006] In the face of stricter emission requirements, as well...
