Abstract—

A comparative analysis of the performance accuracy of the tracking systems of process and energy heliostats was carried out based on the long-term experience of operating a two-mirror big solar furnace (BSF). It is shown that a new additional automatic control system (ACS) is being developed for the upgrade intended to expand the function capabilities of the BSF. The automated control system must maintain dynamics while simultaneously tracking the intersection of two axes of elliptical optical images of the Sun or other celestial objects in the focus of the concentrator from all 62 heliostats simultaneously. In addition, the software-based ACS in development should maintain the previously embedded functions of the automatic temperature control system (ATCS) with the departure of the center of elliptical optical images from all 62 heliostats within 25 angular minutes in order to expand the zone of uniform density. It is proven that the newly developed system of software-based management of heliostats must expand their function capabilities. The optical and geometric parameters (manufacturing accuracy, focal length, and aperture angle) of this installation allow using the solar installation as an astronomical telescope with a midsection size of 42 × 54 m² for registering secondary Cherenkov radiation from gamma-ray sources in the night sky, creating a favorable zone for obtaining a powerful stream of laser beams, as well as efficiently synthesizing molecular hydrogen by thermolysis and electrolysis. It is shown that the automatic software control packages already created or in the process of being created must synchronously and regularly ensure the coincidence of centers of the Sun’s optical images, which have their own variable shapes and densities, depending on the value of the aperture angle with the focal point of the concentrator, for each of the 62 heliostats.

同步软件控制62个定日镜，以增强大型太阳能炉的功能

摘要—

基于操作两镜大太阳炉（BSF）的长期经验，对过程和能量定日镜跟踪系统的性能精度进行了比较分析。可以看出，正在开发新的附加自动控制系统（ACS）以进行升级，以扩展BSF的功能。自动控制系统必须在保持动力学的同时，同时从所有62个定日镜中跟踪集中器焦点处的太阳或其他天体的椭圆光学图像的两个轴的交点。此外，开发中的基于软件的ACS应该保持自动温度控制系统（ATCS）以前嵌入的功能，在25个角分钟内将椭圆形光学图像的中心从所有62个定日镜上移开，以扩大均匀密度区域。事实证明，新开发的基于软件的定日镜管理系统必须扩展其功能。该装置的光学和几何参数（制造精度，焦距和孔径角）允许将太阳能装置用作中剖面尺寸为42×54 m的天文望远镜。²用于记录夜空中来自伽玛射线源的次生Cherenkov辐射，为获得强大的激光束流以及通过热解和电解有效合成分子氢创造了一个有利的区域。结果表明，已经创建或正在创建的自动软件控制程序包必须同步并定期确保太阳光学图像中心的重合，这些光学中心具有自己可变的形状和密度，具体取决于孔径角的值62个定日镜中的每一个都带有集中器的焦点。
