Description
Technical Field
The invention relates to the field of high-altitude wind energy power generation, in particular to a parallel type medium-high altitude wind energy ground generator set.
Background
Wind energy is a clean renewable energy source, and the wind energy stored in the high air exceeds 100 times of the total energy required by the human society. The high altitude wind and high altitude wind energy are characterized in that: high wind speed, high average energy density, wide regional distribution, high stability and continuous throughout the year. How to fully utilize the high-altitude wind is a hot topic which is always focused by scientific researchers for human use, and the advantages of the high-altitude wind are also more and more paid attention to all countries of the world.
The utilization of high altitude wind energy is to collect wind energy in the high altitude, convert the wind energy into mechanical energy, and finally convert the mechanical energy into electric energy or other forms of energy. The existing modes for generating power by using high-altitude wind energy mainly comprise two modes: one is to suspend the generator in the air; the other is to place the generator on the ground. The power generation system with the generator suspended at high altitude cannot realize good control and large power generation in the air part due to the problems that the weight and the volume of the air system cannot be too large and the like; the generator is arranged on the ground, so that the problems can be solved.
The high-altitude kite type power generation system and the umbrella type wind power system both adopt a mode of arranging the power generator on the ground to generate power, but because the power generation mode is intermittent power generation, in order to improve the stability and the power generation capacity of wind power generation, in the prior art, a series ground power generation system is mostly adopted, for example, application numbers 201110151521.3, 201110176767.6, 201110176768.0 and 201520366293.5 are respectively arranged on two sides of the power generator, namely, a plurality of winches are respectively arranged on two sides of the power generator, and are respectively connected with an aerial acting umbrella or a kite through cables, and in actual use, the winches are controlled by an external control part, so that the acting umbrella or the kite at the other end of the period of time is ensured to act when one end of the acting umbrella or the kite starts to be recovered to act again, and the power generator is kept in a working state all the time, thereby improving the power generation capacity of the power generator. However, the above solution still has major drawbacks: because the windlass at both ends sets up in the both ends of generator through the main shaft respectively, if want to improve the generated energy of system, the common practice in this field is a plurality of reels of establishing ties respectively at both ends, so lead to two major axes of generator both ends to need connect, and because the major axis adopts the minor axis to make up, the axiality requirement is higher to lead to greatly increased the power generation system installation degree of difficulty. In addition, because the windlass is connected in series with the two ends of the generator, the windlass at each end of the generator must do work or do not do work at the same time, that is to say, the working umbrella or kite connected with the windlass at each end must be the same as the upper part and the lower part, thus the power generation efficiency is difficult to be greatly improved, the utilization rate of the whole power generation system is low, and great waste is caused.
