The Wind Turbine Performance Testing System of Vertical Axis Wind Brushless DC Generator

摘要: 为了环境的可持续发展，世界各国越来越重视新能源的开发与利用。风能就是其中一种被广泛关注并开发的新能源。在风能资源的开发中，离网型垂直轴风力发电机正逐渐成为研究的热点之一。在研制、设计垂直轴风力发电机的过程中，需要开发相应的测试系统来提供试验数据参考，便于风力发电机的进一步研制。本测试系统基于虚拟仪器是针对某型垂直轴无刷直流发电机组而设计的。本系统能够对该垂直轴风力发电机组的风轮特性进行测试，测试时利用无刷直流电机的特性，测试出多种不同工况下的风轮特性曲线，即转速与风轮的机械功率之间的关系曲线。设计者通过该曲线既可以选择最佳的设计工况，也可以确定切入风速的大小。

Abstract: In order to achieve the sustainable development of energy and environment, almost every country pops into development of new energy resource. Wind power is one of new energy resource, which has been an advanced subject paid close attention extensively. And off-grid the vertical axis wind turbine system is becoming one of hot issuse of wind turbine system researching. In researching vertical axis wind turbine system, researcher needs a testing system supplying the data of experiment to get a new level. The testing system is desgined for a vertical axis wind brushless dc generator. The system could test the of wind tubine perfomance of the vertical axis wind brushless dc generator, and it could get many wind turbine perfomance curves which is the relationship curve between rotated speed and the mechanical power in different conditons. The designer could choose the best design plans and the cut-in wind speed by these curves.
