摘要
通过分析全国日照时数表得出:开环系统在太阳能光伏工程中效率不高而并不适合采用。为合理地利用太阳能,提高其跟踪效率而采用混合控制系统。文中着重分析了双轴跟踪的原理,提出了手动式方位角跟踪和自动式八方位高度角跟踪,引出了分级接收跟踪原理,设计了软件流程并和一套任意方位跟踪系统。运行结果表明,该系统能实现太阳光任意方位检测并迅速跟踪,有效降低系统运行功耗,减少机械结构损耗,跟踪精度可调,可望在太阳能光伏工程中获得应用。
The open system is not suitable for adoption in solar photovoltaic engineering because of its inefficiency through analyzing the national sunshine duration table.Using the mixture control system can enhance its track efficiency and make full use of solar energy reasonably.The paper analyzed the two axle track principle emphatically,then proposed the manual azimuth tracking and the automatic altitude angle tracking of 8 positions,educed hierarchical receive track principle,designed the software flow and a su...
