Solar tracking system for high-power concentrating photovoltaic electric heating co-generation system

Abstract

The invention discloses a solar tracking system for a high-power concentrating photovoltaic electric heating co-generation system. The solar tracking system comprises a PLC (Programmable Logic Controller) central controller and an azimuth angle adjusting servo motor, an altitude angle adjusting servo motor, an LCD display, a photoelectric tracking receiver and a sun trace tracking control module which are respectively connected with the PLC central controller, wherein the photoelectric tracking receiver comprises a receiver body and a cooling device arranged under the receiver body. According to the solar tracking system provided by the invention, the photoelectric sun tracking and the sun trace tracking are organically combined and comprehensively utilized; a photoelectric sun tracker is subjected to reasonable structure design; and the sensitivity of the tracker for receiving signals, the control precision of the system and the generating capacity of the solar battery pack are all increased.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar tracking system used in a high-power concentrating photovoltaic electric-heat cogeneration system. Background technique [0002] Energy occupies an extremely important strategic position in the national economy. With the depletion of global fossil energy and the gradual enhancement of human awareness of environmental protection, in addition to vigorously carrying out energy conservation and clean and efficient use of traditional fossil energy, accelerating the development and utilization of renewable energy is also one of the important ways. As a renewable energy technology with low-cost prospects, concentrated photovoltaic power generation technology is gradually becoming a forward-looking and strategic new energy technology that supports the sustainable development of my country's national economy. [0003] At present, there are many methods of tracking the sun at...

AI Technical Summary

Problems solved by technology

[0008] There are still some problems in the structural design of the existing photoelectric tracking receiver; if the light surface of the receiver is not clean, it is easy to affect the reception of the light signal by the photoresistor, and the resistance value of the photoresistor will decrease with the increase of temperature. The signal accuracy of the tracking receiver will be affected. If the influence of temperature can be reduced and structural defects can be overcome, the stability of the tracking system and the accuracy of control can be improved, and the power generation of the solar cell module can be increased.
