Embodiment 1

[0064] Embodiment one: if figure 2 As shown, it is a dual-axis (horizontal azimuth and altitude angle) photovoltaic power generation automatic tracking control system, which includes an altitude angle drive circuit and an azimuth drive circuit. The two drive circuits are simultaneously controlled by the sun tracking probe and the wind pressure switch. Circuit KZ control, control circuit KZ includes: typhoon detection and prevention circuit, cloudy day detection circuit, night detection circuit, time control circuit, horizontal azimuth tracking control circuit, altitude tracking control circuit, light-facing surface detection circuit, these circuits The detection signals of the tracking probe and the wind pressure switch control the altitude angle drive circuit and the azimuth drive circuit to make the horizontal azimuth motor M1 and the altitude angle drive motor M2 perform corresponding actions.

Embodiment 2

[0065] Embodiment two: if image 3 As shown, it is an automatic tracking control system for single-axis photovoltaic power generation with altitude angle, which controls the altitude angle driving circuit through the control circuit KZ by the sun tracking probe and the wind pressure switch, and the sun tracking probe only needs to be installed at a height of Angle detection photosensitive elements RG7, RG8 and cloudy day detection photosensitive element RG1 are enough; the control circuit KZ includes: typhoon detection prevention circuit, cloudy day detection circuit, time control circuit, altitude angle tracking control circuit, these circuits track the probe and wind according to the fixed date. The detection signal of the pressure switch controls the altitude angle drive circuit to make the altitude angle drive motor M2 perform corresponding actions.

Embodiment 3

[0066] Embodiment three: as Figure 4 As shown, it is an automatic tracking control system for single-axis photovoltaic power generation in the east and west directions. It is controlled by the tracking probe for azimuth driving circuit through the control circuit KZ. The tracking probe only needs to install a photosensitive element for horizontal orientation detection. RG3, RG4, cloudy detection photosensitive element RG1 and night detection photosensitive element RG2, the control circuit KZ includes: cloudy detection circuit, night detection circuit, time control circuit, horizontal azimuth tracking control circuit, these circuits are based on the detection of the fixed day tracking probe The signal controls the azimuth drive circuit to make the horizontal azimuth motor M1 perform corresponding actions.

[0067] In addition, the wind pressure switch and the circuit related to the wind pressure switch can also be omitted during implementation, and only the sun tracking probe ...

Abstract

The invention discloses a photovoltaic power generation settled date automatic tracking control system, and belongs to the field of solar energy utilization. The prior photovoltaic power generation settled date automatic tracking control system is complex and has overhigh cost and poor reliability. The concept of the invention is as follows: the photovoltaic power generation settled date automatic tracking control system comprises an elevation angle driving circuit or / and an azimuth driving circuit, wherein the two driving circuits are at least controlled by a settled date tracking probe through a control circuit. The photovoltaic power generation settled date automatic tracking control system has the functions of continuous tracking of the initial position after starting, intermittent tracking in the operation process, automatic return of the horizontal azimuth to the due east after the sun goes down, automatic level return of the elevation angle when typhoon arrives, and the like, can be started in any position and all weathers, can automatically search for sun rays and continuously track the sun rays, can adopt a direct-current or alternating-current reducing motor for driving, and has the advantages of low power consumption, high tracking precision, high performance price ratio, simple system and good reliability.

Description

technical field [0001] The invention relates to the field of solar energy utilization, in particular to an automatic date tracking control system in the field of photovoltaic power generation. Background technique [0002] Solar energy is an inexhaustible green renewable energy, and it is the main energy that human beings can rely on in the future. The solar photovoltaic array industry is one of the fastest-growing emerging industries in the 21st century. At present, a large number of solar photovoltaic array power generation adopts a fixed flat structure. Generally, the battery array faces south (the direction mentioned in this article is the northern hemisphere As an example, the southern hemisphere is fixedly placed at a certain angle towards the north). However, the direction of the sun's rays not only rotates 180 degrees from east to west within a day, but the elevation angle also changes from small to large and then from large to small, and it also changes throughout ...
