The world is increasingly paying attention to the development and utilization of wind energy. In areas where there are abundant wind resources, it’s the best way to choose wind operators whose rating wind speed fits closely with the best local wind speed. Small wind generators are widely applied in China. However, there’s still a bright future for them. This paper describes the design of a 5 KW small wind generator, which with the adoption of the current advanced domestic and international style and technology can achieve a high “cost-effectiveness” and has a certain extent of market competitiveness. The design adopts the three-blade horizontal axis form, and the blades are made with high-strength, low-weight popular GRP, thus it has the characteristics of anti-sepsis, anti- acid rain and anti- salinity. Wind generators employ Nd-Fe-B permanent magnet generator, which has large overloading capacity and a small, light and efficient motor. Yaw adopts automatic tail wind regulation, in this way it can manipulate the wind freely and enhance the efficiency in receiving the wind. Automatic unilateral speed limiting is used to protect the generator. As for the charging mode, here the design uses the smart charger control. And the tower employs guy cable steel tube, with relative small floor space, low demand for land, feasibility on hills, by the sea shores and river banks, and on the deserts.This 5KW small wind generator described in this paper is stable and reliable. The material used for the blades and the permanent magnet material used for the generator are waterproof and anti-rust. It’s easy to install and maintain, which is just what the generator is designed for.
