wind power system

Abstract

The invention provides a wind power generation system which comprises a generator, at least two sets of resistance type fans and a rotation type bearing device. The resistance type fans are adjacently and horizontally arranged on the rotation type bearing device in a front-back manner and drive the generator to cut a magnetic line so as to generate electric energy. According to the wind power generation system in the embodiment, wind power generation under the low-height and low-air-speed conditions is achieved by horizontally arranging the resistance type fans; the address selecting range of wind power generation is greatly expanded; the power generation link and the power utilization link can be drawn close to the maximum degree; and the wind power generation system can be organically combined with other new energy power generation schemes to improve the total power generation amount of new energy in unit area.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a wind power generation system. Background technique [0002] In order to obtain stable and high-speed wind resources and reduce the cost of electricity, the current wind power generation is increasingly developing in the direction of tall towers and single-machine large-capacity. However, areas suitable for building such wind farms (for example, northern Xinjiang, Inner Mongolia, northern Gansu, etc.) are often far away from power consumption centers, which leads to a disconnect between power generation and power consumption. heavy burden. [0003] In the field of low wind speed power generation, permanent magnet generators are usually used to convert the mechanical energy of wind turbines into electrical energy, but limited by factors such as materials, technology and cost, the speed of permanent magnet generators is usually not lower than 75 revolutions per minute (rpm) ...
