Design And Implementation Of Sun-tracking Control System For Parabolic Trough Solar

Solar energy as a kind of real-time strong and sparse light energy,is not easy to be fully received,is not conducive to a large number of storage,in order to more effectively absorb solar energy,where we use trough solar chase technology to achieve the first solar energy into easy Storage of thermal energy or electricity,both automatic and accurate chase light,but also reduce its own energy consumption.Trough-type solar chasing light technology using photosensitive resistance and the sun’s trajectory combined to achieve intermittent motor running,not only can do automatic precision chasing light,but also improve the performance of solar energy.Trough solar precision chase light system is based on ATmega 16 single-chip design and implementation,the core structure of the automatic chasing device,divided into two parts of the main control and photosensitive.The main control part includes the main control program,the clock program,the motor drive and so on the program module,the photosensitive part according to the strength of the light,starts the feedback,corrects the light to precisely drives the motor,causes the reflector to rotate intermittently to track the sun,It is mainly through the photosensitive resistor and sun visor to complete.This paper first gives the design of the system,and then produce the corresponding physical model,and finally combined with the actual situation of the mad test.Through the experimental data we can see that the maximum speed of the trough solar energy automatic chase light system motor is 12:30 in winter solstice,.its energy consumption is reduced by 0.5‰,than the original way to chase the way solar energy The overall utilization rate increased by 23.37%.the angle of variation error within 0.05°.The system uses trough solar chase light technology,using single-axis tracking system,in doing accurate chasing light at the same time,but also greatly reduce energy consumption and cost savings.In order to follow the design principles of reliable,economical,efficient,strong anti-interference,easy operation and maintenance,it can be seen from the test samples that the design and realization of the trough solar chase technology is simple,cost-effective and suitable for all kinds of small Solar energy utilization equipment.While the promotion of solar energy is conducive to the use of solar energy has important guiding significance.
