2. Wind generator: it is an electrical device that converts wind energy into mechanical work, drives the rotor to rotate, and finally outputs alternating current. In a broad sense, wind energy is also solar energy, so it can also be said that wind turbine is a kind of thermal energy utilization generator with the sun as the heat source and the atmosphere as the working medium.
Wind power generation is mainly used in the following aspects:
Navigation aided navigation
In modern society, with the development of motor boats, in order to save fuel and improve speed, ancient sailing AIDS have also been developed. Japan, a big shipping country, uses computer-controlled sails to assist navigation on 10,000-ton cargo ships, saving fuel 15%.
Wind heating
With the improvement of people's living standards, the demand for heat energy in household energy is increasing, especially in Europe and North America at high latitudes, where boiling water is a big energy consumer. In order to meet the needs of domestic and low-grade industrial heat energy, wind heating has made great progress.
