Parallel-connection-type mid-high altitude wind energy ground generator set

Abstract

The invention discloses a parallel-connection-type mid-high altitude wind energy ground generator set. The parallel-connection-type mid-high altitude wind energy ground generator set comprises at least one generator (1), a plurality of power winches (4) and a plurality of cable accommodation winches (5); the power winches (4) drive the generator (1) to generate power through cables; the cable accommodation winches (5) are used for reeling the cables passing through the power winches (4); and the power winches (4) are arranged parallel to the generator (1). Compared with the prior art, the parallel-connection-type mid-high altitude wind energy ground generator set has the advantages that the requirement on the coaxiality of spindles is not high, so that the assembly difficulty is low; the winches in the generator set do not affect one another, and can be separately adjusted for working; with the same configuration, the power generation efficiency is higher; the utilization rate of the generator set is higher; and the cable folding descending of an umbrella-shaped wind energy system can be realized through a reversing gear box, and a descending motor does not to be additionally arranged, so that the generator set is simpler in structure.

Description

technical field [0001] The invention relates to the field of high-altitude wind energy power generation, in particular to a parallel ground generating set for mid-altitude wind energy. Background technique [0002] Wind energy is a clean and renewable energy source, and the wind energy stored in the sky is more than 100 times the total energy demand of human society. The characteristics of high-altitude wind and high-altitude wind energy are: high wind speed, high average energy density, wide geographical distribution, high stability, and continuous throughout the year. How to make full use of high-altitude wind energy for human use is a hot topic that scientific researchers have been paying attention to. The many advantages of high-altitude wind energy have also attracted more and more attention from all over the world. [0003] The utilization of high-altitude wind energy is to collect wind energy at high altitude, convert the wind energy into mechanical energy, and final...

Problems solved by technology

However, the above-mentioned solution still has relatively large defects: since the winches at both ends are respectively arranged on the two ends of the generator through the main shaft, if the power generation of the system is to be increased, the common practice in this field is to connect multiple reels in series at both ends, As a result, two long shafts need to be connected at both ends of the generator. Since the long shaft is composed of short shafts, the coaxiality requirements are relatively high, which greatly increases the difficulty of power generation system installation.

In addition, since the winches are connected in series at both ends of the generator, the winches at each end of the generator must do work or not work at the same time, that is to say, the working parachute or kite connected to the winches at each end must be the same above and below, which leads to a decrease in power generation efficiency. It is difficult to greatly improve the utilization rate of the entire power generation system, resulting in a large waste
