A high-power wind power generation device

Abstract

A large-power wind power generation device comprises at least two fans (1), a turbine generator (2), and a solar electric heating device (3). The at least two fans (1) are communicated with an air inlet of the turbine generator (2) by means of parallel gas pipelines. The solar electric heating device (3) is electrically connected to a standby gas tank of each fan (1). The device greatly improves the installed capacity of a single set, the generating capacity is stable, the output voltage is stable, filtering and rectification are not required, the device can be interlaced and laminated in space, and the limited space of a wind field can be more effectively utilized.

Description

technical field [0001] The invention relates to a power generating device, in particular to a high-power wind power generating device. Background technique [0002] At present, among domestic and foreign mainstream wind turbines, the largest single unit is 5 MW. Due to the low wind efficiency (30%-60%), the manufacture of 5 MW units requires a lot of large-scale equipment, which is expensive and expensive. It weighs 756 tons, the blade is 62 meters long, and the engine room weighs 260 tons. The installation requires more than 2,400 tons of special lifting equipment; calculated according to the price of 6,000-8,000 yuan per kilowatt, the cost of a 5-megawatt unit will be 30-40 million. Yuan. [0003] A single thermal power generation unit can easily reach 500 MW, and the largest domestically can reach 1,000 MW. Compared with thermal power generation units, mainstream wind power generation units at home and abroad are insignificant only in terms of power; in the current limit...

[0003] A single thermal power generation unit can easily reach 500 MW, and the largest domestically can reach 1,000 MW. Compared with thermal power generation units, mainstream wind power generation units at home and abroad are insignificant only in terms of power; in the current limited wind field resources of The premise is that increasing the installed capacity of a single unit in the domestic wind power market is the only way for wind power generation. At present, domestic mainstream wind power generation devices use horizontal-axis lift blades. Due to the large space occupied by them, the arrangement of multiple fans requires a certain distance. The installed capacity of the wind farm is greatly limited, so that the large amount of wind resources in the wind farm cannot be fully utilized
