As shown in fig. 1, an embodiment of the present invention provides a method for generating power by using high altitude wind energy, including:
s1: the working umbrella 1 is opened, the working umbrella 1 is lifted under the action of wind power, the working umbrella 1 drives a winch 3 to rotate through a cable 2, the winch 3 is connected with a plurality of parallel power generation electric units, the power generation electric units convert mechanical energy of the winch 3 into electric energy, and the plurality of power generation electric units are connected with a power grid 11 in parallel and transmit the electric energy to the power grid 11;
s2: drawing the umbrella 1, supplying power to the power generation and electric unit by the power grid 11, driving the winch 3 to rotate by the power generation and electric unit, and driving the umbrella 1 to descend by the winch 3 through the cable 2;
repeating S1-S2.
In the embodiment, the umbrella 1 ascends under the action of high altitude wind power, the umbrella 1 is connected with a cable 2, the other end of the cable 2 is connected with a winch 3, and the ascending umbrella 1 drives the winch 3 through the cable 2. The electric convergence mode is selected to transmit energy, specifically, the winch 3 is connected with the plurality of power generation electric units in parallel, the winch 3 rotates to drive the plurality of parallel power generation electric units to rotate to generate power, electric energy generated by the plurality of parallel power generation electric units is transmitted to the power grid 11 after being converged, namely, the electric energy is directly converged at high altitude, and then the electric energy is transmitted to the ground. For a plurality of hoist engine 3 drive the main shaft and rotate, then through the mechanical mode of converging that the main shaft transmits mechanical energy to ground, the energy loss of the mode of transmission electric energy in the transmission course after assembling the electric energy is still less, and transmission energy efficiency is higher, and the output process is more stable. When the number of the motors is large, mechanical confluence leads to overlong shafting, difficult design, large occupied area, poor stability and large vibration. The selected electric confluence is easy to realize, and the reliability and the expansibility are strong.
In some embodiments of the invention, the generator-motor unit comprises a clutch 5, the clutch 5 being used to disconnect or connect the transmission connection between the generator-motor unit and the hoisting machine 3;
s2 comprises the following steps:
the umbrella 1 is furled, the clutch 5 of at least one power generation electric unit is closed to operate, the clutches 5 of the other power generation electric units are separated to stop operation, the power generation electric unit operated by the clutch 5 drives the winch 3 to rotate, and the winch 3 drives the umbrella 1 to descend through the cable 2.
In the embodiment, after the power umbrella 1 is folded, in order to make the power umbrella 1 quickly descend, the power generation electric unit rotates through the electricity of the power grid 11 to wind the cable 2 to pull the power umbrella 1 to quickly descend. Because the umbrella 1 is in a furled state and can descend under the action of gravity, the umbrella 1 does not need to be pulled to descend by winding the cable 2 with excessive energy, and only the clutch 5 is arranged in each power generation electric unit, and at least one clutch 5 is closed to operate, namely at least one power generation electric unit operates to provide power. By the arrangement, the purpose of winding the mooring rope 2 and pulling the acting umbrella 1 can be achieved, and energy can be effectively saved.
In some embodiments of the invention, the clutch 5 of at least one generator-motor unit operates closed, comprising:
determining the number of the power generation electric units with the clutch 5 running in a closed state according to the recovery requirement:
if the umbrella 1 needs to be slowly recovered, the clutch 5 of one power generation electric unit is closed to operate;

The recovery power required for different situations is different, so the number of the power generation motor units in the closed operation of the clutch 5 is different, and the adjustment setting is carried out according to the recovery speed and the actual requirement.
It should be noted that when the power umbrella 1 fails and cannot be folded, it needs to be recovered in an emergency. Because the acting umbrella 1 can not be folded, a larger resistance can be met in the descending process, and larger power is needed to overcome the resistance for recovery, so that more power generation electric units are needed during emergency recovery, and the recovery speed is lower.
It can be understood that the number of the generating electric units is selected only for the above use cases, and in practical design, the number of the working umbrellas 1 can be flexibly adjusted according to the requirements of power and recovery speed of the generating electric units.
In some embodiments of the invention, the generator motor unit comprises at least a first generator motor unit and a second generator motor unit, the first generator motor unit having a greater power than the second generator motor unit;
the clutch 5 of at least one power generating electric unit is operated in a closed state, and comprises:
determining the number of the power generation electric units with the clutch 5 running in a closed state according to the recovery requirement:
if the work umbrella 1 needs to be slowly recovered, the clutch 5 of the second power generation electric unit is closed to operate;
if the power umbrella 1 needs to be quickly retracted, the clutch 5 of the first power generation electric unit is closed to operate;
if the acting umbrella 1 can not be folded and the acting umbrella 1 needs to be retracted in an emergency, the clutch 5 of the first power generation electric unit and the second power generation electric unit is closed to operate.
In this embodiment, at least a first generator motor unit and a second generator motor unit may be provided in which power is sequentially decreased in order to further save energy. And selecting to close the clutches 5 for operating different power generation electric units according to different speed requirements so as to achieve the aim of further saving energy. If rapid recovery is required, the first generator motor unit is operated by the clutch 5. If slow recovery is required, the second generator motor unit is operated by the clutch 5. If the emergency recovery is required, the first generator motor unit and the second generator motor unit need to be operated simultaneously by the clutch 5. It will be appreciated that a plurality of different power generating electrical units may be provided to accommodate more usage requirements.
