Description

A multi-wind turbine wind power generation device

technical field

The utility model relates to the field of wind power generation, in particular to a multi-wind-wheel wind power generation device suitable for areas rich in wind power resources.

Background technique

The current world energy crisis has warned us, and the development and utilization of primary energy in various countries has also stepped into a higher level. Wind energy is a kind of clean primary energy, and its reserves are huge, which is ten times as much as the total amount of water energy that can be developed and utilized on the earth. At present, the energy obtained by burning coal in the world every year is only one-third of the energy provided by wind power in a year. Therefore, both at home and abroad attach great importance to wind power. Vigorously promoting the construction of wind power projects is conducive to adjusting the energy structure and changing the mode of economic development. With the advancement of technology and the development of environmental protection, wind power generation will be able to compete commercially with coal-fired power generation. Its development prospects are very broad, and it is expected to maintain high-speed development for a long time in the future.

Existing wind power technology is not mature. At present, a power generation form in which one tower corresponds to one generating set is mostly used. Considering from the perspective of relative altitude, we can see that in the traditional power generation method, a wind turbine only obtains wind energy at a certain fixed height. If the vertical direction of the tower where the wind turbine is located is regarded as a straight line, and all points on the straight line are filled with wind energy, the current energy utilized by the wind turbine is only the wind energy at a certain point on the straight line. For the entire power plant, only the wind energy on the same altitude plane is used. In fact, the utilization rate of wind energy is not high, and its utilization efficiency may be doubled.

The wind power in many areas is intermittent, and the worse situation is that in some areas, the wind power is less during the summer and daytime when the power demand is higher; wind power generation requires a large amount of land to build wind farms to produce more electricity The utilization of wind energy is severely restricted by geographical location, so the development of wind power technology must be accelerated. The current wind power generation is still immature, and there is still considerable room for development. The development of wind power has become a global trend. We must keep up with the pace and do a good job in relevant knowledge reserves and technology research and development.
