Embodiment Construction

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

Abstract

Provided is an offshore booster station which comprises a base portion fixed to a seabed, a platform and a device layer. The device layer is provided with a main transformer. The high-voltage side of the main transformer is electrically connected with a submarine cable through a high-voltage bus; the high-voltage side of the main transformer is electrically connected with the high-voltage bus through a first circuit breaker; and one end of the submarine cable is electrically connected with the high-voltage bus through an isolating switch, and the other end of the submarine cable is electrically connected with an onshore substation through a second circuit breaker. The offshore booster station realizes double protection on both the submarine cable and the high-voltage bus directly by cutting off the first circuit breaker and the second circuit breaker. Therefore, electrical switch devices are reduced, and space occupation area is reduced to enable devices of the whole offshore booster station to be arranged more compact.

Description

technical field [0001] The invention belongs to the technical field of renewable energy, and in particular relates to an offshore booster station. Background technique [0002] Offshore wind power has become the focus of renewable and clean energy development due to its characteristics of high wind speed, low turbulence, and low environmental impact. my country's offshore wind energy reserves that can be developed at a height of 10m are about 750 million kilowatts. With the increase of policy support, the development of offshore wind power in my country's offshore wind farms is vigorously emerging. [0003] At present, most of the offshore wind power under construction in my country is 10-30km offshore, and the planned capacity of the project is 200-300MW, which is generated by a group of 3MW-6MW offshore wind turbines, and the power is sent to the offshore step-up station through the submarine cable power collection link. Then the main transformer of the offshore step-up st...
