Description

Technical Field

[0001] The present application belongs to the field of wind energy utilization, and in particular relates to a wind speed adaptive triboelectric-electromagnetic induction hybrid wind energy generator based on an inertial drive conversion mechanism and its operation steps. Background Art

[0002] With the rapid development of economy, the use of electric energy is gradually increasing. At present, more than 80% of my country's electric energy is generated by fossil fuels such as coal, oil and natural gas. With the continuous large-scale consumption of these non-renewable energy and the pursuit of environmental quality, it is no longer in line with the current concept of sustainable development. The development of new energy power generation is an urgent and long-term strategic task today.

[0003] The technology of using solar energy, wind energy, tidal energy or mechanical energy for micro-nano power generation has attracted widespread attention, and it is mixed with triboelectric nanogenerators that operate by friction electrification and electrostatic induction coupling effects. Among them, wind energy is a form of solar energy conversion and a renewable natural energy that does not produce any pollution emissions. Compared with solar energy, biomass, geothermal energy and ocean energy generation, wind power generation is the new energy with the most commercial scale development conditions in terms of technology and economy.

[0004] In recent years, a new type of wind power generation system has emerged in the world, the variable speed constant frequency generator set. Because its speed is not limited by the output power of the generator, it has a relatively good wind power collection and conversion efficiency. At low wind speeds, the speed can change according to the wind speed to improve the wind power conversion efficiency, and at high wind speeds, the speed change is controlled by adjusting the wind turbine pitch angle to ensure the safe operation of the variable speed constant frequency generator set. However, due to the late development and production of wind turbines in my country, its related core technologies are relatively lacking, and wind turbines have problems such as low collection efficiency, imperfect wind energy collection function of the device, and inability to better adapt to various working environments.
