Abstract
A high precision sun position transducer is composed of a convex lens, a solar battery plate, a photosensitive diode and a signal processing circuit in a lighttight tubby shell. The sun imaging is formed by the convex lens. The transducer enables the sun imaging to fall on the solar battery plate or the photosensitive diode and gets the position of the sun after the signal processing of the solar battery plate or the photosensitive diode by the signal processing circuit. The utility model is applied to the concentration photovoltaic system, enabling the system to track the sun accurately.
Description
Affiliated technical field
The high-precision sun position transducer is the front end sensors of concentrating photovoltaic power generation equipment, and it makes concentrating photovoltaic power generation equipment realize that high precision is with day.
Background technology
In recent years, along with solar photovoltaic technology constantly ripe with popularize, solar energy power generating progressively by supplementary energy to the basic energy resource transition, the especially appearance of pv grid-connected plant system makes the prospect of solar energy power generating more and more brighter.Because dull and stereotyped photovoltaic generation is with high costs, and concentrating photovoltaic power generation really can be realized solar energy power generating cheaply, so concentrating photovoltaic power generation becomes the hot topic of present research.The core technology of concentrating photovoltaic power generation be to solve high precision with day, resolving high precision goes out the concentrating photovoltaic power generation technology with competence exertion in the future advantage.In order to realize that high precision follows day, a kind of high-precision sun position transducer becomes necessary.
Summary of the invention
In order to overcome the low and high deficiency of cost of existing sun position sensor precision, the utility model proposes a kind of sun position sensor, the precision that this sun position sensor can detect position of sun can reach 0.5 °, and simple in structure, with low cost.
The technical scheme that its technical matters that solves the utility model adopts is: in light tight tubbiness shell (2), be made up of convex lens (6), solar battery sheet (7), photodiode (8) and signal processing circuit (5).When convex lens (6) the rough alignment solar time, the picture (the round hot spot of one 2 millimeter) that the sun on base plate (3), can occur, hot spot can be fallen on solar battery sheet (7) or the photodiode (8), signal processing circuit is gathered the signal on solar battery sheet (7) and the photodiode (8) then, these signals are handled through signal processing circuit (5), just can get sunny positional information, thereby reach the purpose of high Precision Detection position of sun.
The beneficial effects of the utility model are, can the high Precision Detection position of sun, and simultaneously simple in structure, stable and reliable for performance, with low cost.
