Embodiment 2

[0025] Such as figure 2 As shown, Embodiment 2 of the present invention provides another marine rescue system based on the Internet of Things. This system is improved on the basis of the system structure of Embodiment 1 above: between the first inverter 17 and the power grid 19, a Booster 21. The voltage of the alternating current transformed by the first inverter 17 is boosted by the booster 21 for long-distance transmission and reducing power loss. In addition, the storage battery 15 is also connected to a DC load 23 through a third DC / DC converter 22 . Through the third DC / DC converter 22, the electric energy of the storage battery 15 is adjusted to convert it into the current available for the DC load 23, so that various DC loads 23 on the island can directly use electric energy, for example, to drive the photovoltaic panel 13 for timing Rotating drive motors, signal lights on islands, and more.

[0026] Principle of the present invention is as follows:

Abstract

The invention provides an ocean wave energy and solar energy combined power generation system, and belongs to the technical field of ocean. The ocean wave energy and solar energy combined power generation system comprises a wave energy power generation assembly arranged around an island, a solar power generation assembly erected on the island, a direct current grid-connected module, an energy storage module and an inverter module. The wave power generation assembly and the solar power generation assembly are connected with the input end of the direct-current grid-connected module, the output end of the direct-current grid-connected module is connected with the energy storage module, and the energy storage module is connected with a power grid through the inverter module. According to the ocean wave energy and solar energy combined power generation system, multi-energy complementary power generation and diversified electric energy output under the ocean environment are achieved, and the power generation efficiency is higher compared with single power generation.

Description

technical field [0001] The invention belongs to the technical field of ocean rescue, and in particular relates to a combined power generation system of ocean wave energy and solar energy. Background technique [0002] Wave energy power generation uses wave energy as the driving force to produce electric energy. Wave energy is a nearly unlimited energy resource. The use of wave energy power generation has brought power supply protection and great convenience to industrial and domestic electricity consumption. At present, the commonly used wave energy power generation technology is to use wave energy collection mechanism to collect wave energy, convert the energy generated by wave fluctuation into electric energy through energy conversion mechanism and generator, and connect the generator directly to the power grid or directly to the electrical load. The generated electric energy is directly connected to the grid or used. [0003] However, due to the intermittency and volatil...
