Hence heliostats can always follow the position of the sun, special algorithms are needed to control the motor of the mirror with pinpoint accuracy.
Heliostats are self-aligning mirrors for precise guidance of sunlight. The directed sunlight can either be used for energy generation or it can be used to illuminate windowless areas, to brighten shaded objects or as a source of natural light.
Special algorithms determine the engine speed
Algorithms are used for high-precision angle calculation of the heliostat mirror relative to the sun and the target point. The continuous tracking of the mirror is achieved by dynamic calculation of the motor speed and the corresponding reduction ratio. Thus no step movements are visible. The synchronization of the time is done by a GPS signal or via an internet connection to a server with Network Time Protocol (NTP).
The control system consists of compact, industrial and robust system components. These are either placed directly at the heliostat in the control box or in a nearby technical room. The control system is operated via a laptop or tablet computer. The connection of the heliostat control to a local network allows access via W-LAN. There is also the possibility for remote access.
System made of robust and weatherproof materials
The plant is of very robust construction. Only highly tempered materials and wear-resistant drive components are used, which in particular withstand the changing climatic conditions. The drive components with the gearboxes are designed to withstand wind speeds of up to 180 km/h.
