Description

technical field

[0001] The invention relates to the technical field of photothermal power generation, in particular to a control system for a photothermal power generation heliostat. Background technique

[0002] Tower-type solar thermal power generation uses a set of heliostats that independently track the sun to reflect sunlight to a receiver fixed on the top of the tower, generate high temperature and heat the working fluid to generate superheated steam, and drive the turbogenerator to generate electricity, thereby converting solar energy converted into electricity. Heliostats not only have the largest number and occupy the largest area in the power station, but also have the largest investment. The tracking effect of heliostats seriously affects the utilization efficiency of solar energy. Studies have shown that the energy receiving rate differs by 37.7% between tracking the sun and not tracking the sun. Accurate tracking of the sun can greatly improve the thermal effi...
