1、离心变浆轮毂在小型风力发电机推广中的价值——离心变浆轮毂给小风电发展带来希望章红涛长沙远广机电科技有限公司湖南省长沙市410000摘要：根据对我国中小型风力发电机现状的了解，由于目前已有的变浆系统复杂和价格高，定浆距型风力发电机占据绝大多数市场份额，其性能上的缺陷严重阻碍了中小型风力发电机的推广，由大型机推出变浆型机组后市场的迅速扩大，就充分说明了小型机发展道路上的障碍所在。为促进我国中小风力发电机的发展，专门开发设计了一种新型的离心变浆轮毂，是以独特的结构和离心控制方式组成，能自动依据转速变化来同步调整每个叶片的迎风角度，使得风力发电机在额定转速上稳定运行，极大

2、减小风速和负荷变化对转速和输出电压的影响，保证输出电压能稳定在额定电压值附近，误差不超过10%。同时大幅减小了强风作用在叶片上的冲力，在强风中不需停机而能正常发电，较大幅度的提高了风能利用率，还能在设计塔架和叶片时适当减少材料消耗，降低成本和造价，给中小型风力发电机的推广和市场发展带来更好的前景。关键词：风力发电机；变浆轮毂；离心变浆中图分类号：TP文献标识码：BCentrifugalvariablepitchwindturbinewheelsinsmallintheexpansionofvalue-Centrifugalvariablepitchtosmallw
