摘要
为了更好的利用太阳能,自动跟踪系统越来越多的应用于太阳能行业中。基于可编程逻辑控制器(PLC)的太阳能电池板自动跟踪系统,包括硬件和软件两部分,其中硬件包括PLC输入输出端口、信号处理单元、驱动部分;软件包括PLC的控制和监控程序两部分。太阳能电池板自动跟踪系统使光伏电池板能实时跟踪太阳关照,从而最大限度的获得太阳能,有效地提高太阳能的利用率和光伏发电系统的效率,降低了光伏并网发电成本,具有理论研究意义和应用推广价值。
In order to make better use of solar energy, more and more automatic tracking system are used in the solar industry. The solar panels tracking system based on program- mable logic controllers including hardware and software parts. The hardware input and out- put ports of hardware, signal processing unit, driving part; software include two parts which PLC control and monitoring program. The photovoltaic module in the system can track the sun simultaneously, then the maximum sun energy will be obtained, which has effectively improved the utilization ratio of solar energy and efficiency of photovoltaic power generation system and has reduced the cost of grid-connected PV power generation with signiflcances of theories research and application values of applications promotion.
