为使光伏系统更为高效，Beckhoff自动化公司日前发布了TwinCAT太阳能方位技术数据。这种大规模数据使得全球任何方位任何时间的太阳能角度精确计算成为可能。而这种计算甚
至不需要用到感应器。
这种适应性极强的软件极为适宜聚光太阳能和光伏太阳能电厂的设计以及自动追踪太阳位置时的应用。
这种控制算法的水平方位角以及垂直方位角的计算精准度达到了不可思议的+ - 0.001度。因此也可以被用于其他设备或者装置。例如建筑自动化或者风力涡轮机上。
这种TwinCAT太阳能定位计算软件数据库能够极为精准的确定整年太阳太阳升起时，中午时以及傍晚时的角度。而这种角度计算需要的特定的数据，时间以及精准的地理位置经纬度
。如果用户需要更为精准的计算，该软件甚至可以将时差，潮汐影响，地形位置影响等因素考虑在内。
26.08.2010: In order to bring cost-effective and high-performance embedded PC-based control to solar power plants, Beckhoff Automation has released the TwinCAT Solar Position Algorithm library. This feature-laden function block permits the exact calculation of sun angles anywhere in the world at any time,
without the use of sensors. This flexible TwinCAT solution is ideal for parabolic mirror and photovoltaic systems as well as for other solar power plant designs that automatically track the sun's position for optimum utilization of the sun's rays. The control algorithm, which calculates the zenith and azimuth angles of the sun with an impressive precision of ±0.001°, can also be used for other applications such as in building automation or with wind turbines for shadow flicker calculations. The TwinCAT Solar Position Algorithm software library enables high-precision determination of sun angles and the times for sunrise, solar noon and sunset year-round. The calculation of sun angles with the TwinCAT library simply requires the specification of the date, time and exact longitude and latitude of the location (e.g. through a GPS system). Depending on the required precision, the algorithm can take into account additional parameters such as the time zone, the height above mean sea level, the slope of the ground or the orientation of the object, as well as the air temperature and pressure, which influence atmospheric refraction. …
