Abstract: 在海洋能发电中,潮流发电具有广阔的发展前景.为在实验室进行潮流发电的前期研究,设计了潮流发电模拟装置.由于近海岸潮流能分布较大,在模拟装置中进行近海岸的潮流流速模拟,即造流.在模拟装置的控制系统中,通过上位机控制变频器输出电源的频率和相序,从而驱动三相异步电动机带动双向叶轮泵推动水的流动.为此在上位机上设计了LabVIEW操作界面以及程序框图,利用VISA技术进行数据发送与接收,将流速对应的频率信号发送给变频器,并将流速传感器采集到的流速信号接收到上位机进行实时显示.研究稳定流速和变化流速的造流方法,对稳定流速、椭圆余弦波流速和沿岸流流速进行造流实验,结果表明模拟流速与预设流速总体误差较小,较好地实现了实验室潮流发电的模拟.
