Description
技术领域technical field
本发明涉及新能源技术领域，尤其是一种小型风力发电设备。The invention relates to the technical field of new energy, in particular to a small-scale wind power generation equipment.
背景技术Background technique
随着社会对能源需求的日益增多，开发各种新能源的利用成为了现在研究的热点，风力发电就是其中重要的一部分。风力发电机是将风能转换为机械功的动力机械，又称风车。广义地说，它是一种以太阳为热源，以大气为工作介质的热能利用发动机。风力发电利用的是自然能源。相对柴油发电要好的多。但是若应急来用的话，还是不如柴油发电机。风力发电不可视为备用电源，但是却可以长期利用。With the society's increasing demand for energy, the development of various new energy sources has become a research hotspot, and wind power generation is an important part of it. A wind turbine is a power machine that converts wind energy into mechanical work, also known as a windmill. Broadly speaking, it is a thermal energy utilization engine that uses the sun as the heat source and the atmosphere as the working medium. Wind power utilizes natural energy. Much better than diesel power. But if it is used in an emergency, it is still not as good as a diesel generator. Wind power cannot be regarded as a backup power source, but it can be used for a long time.
风力发电的原理，是利用风力带动风车叶片旋转，再透过增速机将旋转的速度提升，来促使发电机发电。依据目前的风车技术，大约是每秒三公尺的微风速度(微风的程度)，便可以开始发电。The principle of wind power generation is to use the wind to drive the blades of the windmill to rotate, and then increase the speed of rotation through the speed increaser to drive the generator to generate electricity. According to the current windmill technology, power generation can be started at a breeze speed (the degree of breeze) of about three meters per second.
风力发电正在世界上形成一股热潮，因为风力发电没有燃料问题，也不会产生辐射或空气污染。Wind power is becoming a craze around the world because it has no fuel issues and doesn't produce radiation or air pollution.
现有的风力发电设备一般都是大型的风电机组，不适合个人和家庭使用，同时大型风电机组对风场要求比较高，不适合大面积推广。Existing wind power generation equipment is generally large-scale wind turbines, which are not suitable for personal and family use. At the same time, large-scale wind turbines have relatively high requirements for wind farms and are not suitable for large-scale promotion.
