Wind energy power system with tandem bidirectional drive

Abstract

The invention discloses a series bidirectional driven wind power system. The system comprises two winches, two umbrella-type wind power devices and a central control device, wherein the two winches are connected to two ends of a transmission shaft of a working device respectively; the two umbrella-type wind power devices are used for collecting wind energy at high altitude, converting the wind energy into mechanical energy and outputting the mechanical energy through working ropes respectively, and the working ropes are connected to winding drums of the two winches by winding in the same winding direction; and the central control device is connected with and controls the two umbrella-type wind power devices and the two winches, and the central control device is used for controlling the umbrella-type wind power devices to asynchronously stop in declining stages in each working period and stop outputting the mechanical energy. Compared with a single umbrella-type wind power system, the series bidirectional driven wind power system has the advantage that: continuity and stability of energy output of the high-altitude wind power system are greatly improved.

Description

technical field [0001] The invention relates to a wind energy conversion system, in particular to a series-connected bidirectional drive wind energy power system capable of continuously providing energy. Background technique [0002] The research report of environmental and climate scientists Cristina Archer and Ken Caldeira pointed out: the wind energy stored in the sky is more than 100 times the total energy demand of human society. Wind energy is a clean and renewable energy. Making full use of high-altitude wind energy for human use has been a hot topic that scientific researchers have been paying attention to. The many advantages of high-altitude wind energy have attracted more and more attention from all over the world. [0003] 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. The utilization of high-altitude win...

Problems solved by technology

[0004] The collection and utilization of high-altitude wind energy is an emerging research field all over the world. As a kind of clean energy with abundant reserves, high-altitude wind energy is difficult to collect and control, which leads to the low power generated by many ordinary high-altitude wind power systems. unstable

[0005] Intermittent high-altitude wind power generation technology has been able to provide relatively large power generation capacity, but due to the fact that there is no power generation for a period of time during the downlink of the power umbrella, resources are wasted during this period
