Abstract

The invention discloses an offshore wind power system and an offshore wind power generation and transmission system, and belongs to the field of wind power generation. The offshore wind power system comprises an offshore wind generating set matrix, an offshore boosting transformer substation, an offshore converter station and a direct current transmission line which are electrically connected in sequence; the offshore wind generating set matrix comprises a plurality of wind generating sets, and each wind generating set comprises a generator, a voltage source type converter and an in-set boosting transformer substation which are electrically connected in sequence; the offshore wind generating set matrix outputs low-frequency alternating-current electric energy to the offshore boosting transformer substation, the offshore boosting transformer substation boosts the low-frequency alternating-current electric energy and outputs the boosted low-frequency alternating-current electric energy to the offshore converter station, and the offshore converter station converts the boosted low-frequency alternating-current electric energy into direct-current electric energy and transmits the direct-current electric energy through the direct-current power transmission line. The frequency of the low-frequency alternating-current electric energy is lower than power frequency. According to the embodiment of the invention, the conveying capacity of the whole offshore wind power system can be improved.

Description

technical field [0001] The application belongs to the field of wind power generation, and in particular relates to an offshore wind power system and an offshore wind power transmission system. Background technique [0002] Wind power generation technology is a technology that converts wind energy into electrical energy. Specifically, wind power generators can be used to convert wind energy into electrical energy. With the development of wind power technology, offshore wind power technology has become one of the key research. In offshore wind power technology, wind turbines can be installed at sea, and the electrical energy output by wind turbines needs to be transmitted over long distances before being transmitted to land, resulting in poor transmission capacity of offshore wind power systems. Contents of the invention [0003] Embodiments of the present application provide an offshore wind power system and an offshore wind power transmission system, which can improve the...
