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, yet 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. In form, blades are the core of the wind generator, and according to the rotation axis direction, wind operators are divided into two types: the horizontal-axis type and the vertical-axis type. The impeller of the horizontal-axis type is needed to adjust its position when the wind direction changes, and we have to consider the balancing problem of the large impeller; while that of the vertical-axis type needn’t change its position when the wind direction does, and has no balancing problem of the impeller, furthermore, its design is more simpler. The only problem is that the system extracting wind energy coefficient is low, which means with the same generating capacity the blades should be larger.The design adopts the three-blade horizontal axis form, and the blade is 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 五邑大學(xué)本科畢業(yè)設(shè)計(論文)IIIspace, 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 in the blade and the permanent magnet material used in the generator are waterproof and anti-rust. It’s easy to install and maintain, which is just what the generator is designed for. Key words wind power generation Permanent magnet GRP
