Embodiment 1

[0038] A mobile power generation and energy storage ship is used as a means of transportation, which consists of 7 vertical axis wind turbines 201, a large-capacity energy storage liquid storage tank 202, a mobile power generation and energy storage ship body 203 and a mooring anchor 204;

[0039] see image 3 : The whole process is: the mobile power generation and energy storage ship sails to the anchorage of the offshore wind farm for anchoring power generation and energy storage and stores the electric energy in the energy storage liquid of the mobile power generation and energy storage ship, and the mobile power generation and energy storage with full energy The ship sails to the energy storage fluid exchange pump station on the coast through its own power plant, and exchanges the energy storage fluid with full energy storage and the energy storage fluid without energy storage through the energy storage fluid exchange pump station, and the energy storage fluid exchange pump...

Embodiment 2

[0041] A floating power generation platform and a transport ship are used. The transport ship sails to the anchorage of the offshore wind farm for anchoring. The floating power generation platform generates energy and stores it (it can be wind power or solar power) and stores the electric energy in the energy storage fluid of the transport ship. The energy transport ship sails to the energy storage fluid exchange pump station on the coast through its own power plant, and exchanges the energy storage fluid with full energy and the energy storage fluid without energy storage through the energy storage fluid exchange pump station. The energy storage liquid with full energy in the exchange pumping station is exchanged with the onshore converter station in two directions; the onshore converter station uses the energy storage liquid with full energy to generate electricity through the vanadium battery inverter power generation system and sends it to the load center through the power t...

Abstract

The invention relates to an offshore movable wind power generation system. The offshore movable wind power generation system is characterized in that a movable power generation energy storage ship navigates to an offshore wind power plant anchorage and carries out anchoring power generation energy storage, and stores electric energy into an energy storage liquid of the movable power generation energy storage ship, the movable power generation energy storage ship which fully stores the energy navigates to a longshore energy storage liquid exchange pump station, and exchanges the energy storage liquid which fully stores the energy, with the energy storage liquid which does not store the energy through the energy storage liquid exchange pump station, and the energy storage liquid which fully stores the energy in the energy storage liquid exchange pump station is subjected to bidirectional exchange with a longshore converter station; and the longshore converter station uses the energy storage liquid which fully stores the energy for generating power and conveys the electric energy to a load centre through a power transmission and distribution system, and meanwhile, the longshore converter station returns the energy storage liquid which is already used for generating power to the energy storage liquid exchange pump station. The offshore movable wind power generation system disclosed by the invention is capable of conveying the electric energy to shore for utilization without the limit of an offshore distance by virtue of the characteristic that the energy storage liquid is capable of being subjected to long-distance transportation without energy losses; and meanwhile, the energy storage liquid is capable of being repeatedly used without damages.

Description

technical field [0001] The invention relates to an offshore mobile wind power generation system. Background technique [0002] my country is rich in marine wind resources, and using them to generate electricity is a very green and environmentally friendly energy utilization method with huge development prospects. However, the vast majority of existing wind turbines are installed on the ground in a rigidly fixed manner, which limits the application of wind power generation technology in the ocean (mainly because the rigidly fixed foundation is difficult to construct. The cost is high, and it is almost impossible for the deep sea). For this reason, technicians in the industry have developed various floating wind turbines that can be adapted to the deep sea, such as the "offshore wind power generation device" disclosed in the Chinese patent literature (public number: CN201416515, Open date: March 3, 2010), "Flexible floating foundation for offshore wind turbines" (public numbe...
