Researching of a Performance Testing System Principle for the Small Size Wind Turbine Generator

本文为离网型风力发电机虚拟仪器性能测试原理的研究,利用相应的软件LabVIEW及相关配套硬件设备,设计了风力机基本性能参数的测试系统。在考虑到强电、弱电信号传输分开,内部供电电源与信号线路隔离以及信号屏蔽等问题,设计出了测试机箱方案。通过在实验室实验,测得了风力发电机的转速与风力发电机功率的数据,从而做出了一条转速与功率的关系曲线,为评估和改进风力发电机的性能提供依据。

Based on the Visual instruments technology, this paper is mainly about the researching of a performance testing system principle for the small size Wind Turbine Generator. This performance testing system is based on the virtual instruments （VI） and relative hardware. Considering detach strong and feeble electricity signal, inside electricity supply and signal wire, we devise the testing machine box. Through experiment in the lab, test the datum of WTG rotate speed and power, and make out the curve of rotate speed and power. We can estimate the performance of the WTG and improve it according to the results.
