Problems solved by technology

At low wind speeds, large vertical wind turbines are difficult to start, or cannot be started at all, resulting in a waste of resources for the generators; at normal wind speeds, although large horizontal axis wind turbines can start and work, the power generation of the generators The efficiency is not high, and it is often not at full power; when the wind is super strong, the speed of the generator is significantly accelerated, even exceeding the rated power of the generator itself. At this time, the generator is in a dangerous state, and the generator components may be damaged. be damaged, and the ultra-high power output also has certain dangers
In addition, because the natural wind will have small wind, low wind speed or high wind speed all the time, the power generated by the generator is extremely unstable, and it will cause an impact on the power grid when connected to the power grid.

Abstract

The invention relates to a horizontal shaft wind driven generator, which comprises a tower column, an air storage tank, an impeller power machine and a generating set, wherein the generating set comprises a generator, an impeller and a rotating shaft, and the generator is an internal rotor generator; the impeller power machine is arranged in front of or behind the generator and comprises a turbine and a fan housing, the turbine drives a rotor of the generator to rotate, and the fan housing is connected with the rotor of the generator; and an air inlet pipe is arranged between the air storage tank and the impeller power machine, the impeller power machine is provided with an air inlet and an air outlet, and the air inlet pipe is connected with the air inlet. When the wind speed is low, the impeller power machine can be used as an auxiliary starting device of the generator; in the normal state, the impeller power machine can accelerate the rotation of the generator so that the generator reaches a full generation power state; when the wind speed is ultrahigh, the impeller power machine can be used as a braking device of the generator; and the impeller power machine can also be used as a radiating device of the generator.

Description

technical field [0001] The invention relates to a horizontal axis wind power generator. Background technique [0002] At present, there are still many problems in the large-scale horizontal axis wind turbines that use grid-connected power generation, and these problems are caused by many instabilities in natural wind. At low wind speeds, large vertical wind turbines are difficult to start, or cannot be started at all, resulting in a waste of resources for the generators; at normal wind speeds, although large horizontal axis wind turbines can start and work, the power generation of the generators The efficiency is not high, and it is often not at full power; when the wind is super strong, the speed of the generator is significantly accelerated, even exceeding the rated power of the generator itself. At this time, the generator is in a dangerous state, and the generator components may be damaged. be damaged, and the ultra-high power output also has certain dangers. In additi...
