Abstract
A photovoltaic full-automatic tracking system serves a photovoltaic tracking manner as a main tracking manner, detects light through a light intensity detection circuit in strong light, performs photovoltaic tracking through a deviation, and can automatically change into a visible sun motion tracking manner in the condition of a long-time dark cloud weather. When sun light reaches a sensor, sensing signals given by a photovoltaic cell array and a sun location deviation are stored in a controller via a pre-amplifier and a voltage following device; and the controller performs certain process according to a preset program, and then control a stepping motor to rotate to allow a condenser to rotate with movement of the sun, so that tracking can be achieved. The photovoltaic full-automatic tracking system is simple in structure, is easy to control, is low in cost, and is stable in operation, and can be applied to a grid-connected photovoltaic system and an off-grid photovoltaic system.

Technical field
The invention belongs to photovoltaic generation tracking technique field, particularly relate to a kind of photovoltaic generation full-automatic tracking system.
Background technology
Sun power can continue as a kind of the green regenerative energy sources used forever, has huge Application and Development potentiality.But because the output characteristics of photovoltaic cell and the change of outside environmental elements have much relations, the photovoltaic cell photoelectric transformation efficiency of scale of mass production is still not high and expensive.Solar energy utilization ratio is improved in photovoltaic generating automatic tracking device room, reduces the effective way of photovoltaic generation cost.At present, conventional tracking looks daily motion track following and photoelectric tracking mode.But tracking control technology both domestic and external is not generally very ripe, generally can not ensure the reliable and stable operation of whole system, and complexity is relatively high.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provides a kind of photovoltaic generation full-automatic tracking system rational in infrastructure, easy and simple to handle.
The technical scheme that the present invention takes is: a kind of photovoltaic full-automatic tracking system, adopt photoelectric tracking mode as main tracking mode, when light is stronger, light intensity detection circuit is adopted to detect light, deviation carries out photoelectric tracking, if running into the weather conditions such as black clouds blocks for a long time is that system transfers to automatically looks daily motion tracking mode.
Described a kind of photovoltaic full-automatic tracking system, is characterized in that: primarily of compositions such as controller, photosensitive tube, light intensity detection circuit, stepper motor, motor drivings.
The photoelectric tracking mode of described photovoltaic full-automatic tracking system, when solar irradiation is mapped on sensor, the transducing signal that photovoltaic battery array and position of sun deviation provide, be saved in after entering prime amplifier, voltage follower in controller, control step electric machine rotation after certain process is carried out according to the program preset by controller, make condenser move along with the sun and rotate, thus reach the object of tracking.
Described photovoltaic full-automatic tracking system, its condenser adopts multiple reflection mirror parabolic condenser.
Described photovoltaic full-automatic tracking system, its tracking means mechanical mechanism forms primarily of support, stepper motor, transmission gear, position switch and pedestal.Rotate to be with array in order to larger Driving Torque can be produced, transmission gear wheel is connected with stepper motor, azimuth axis is perpendicular to ground, pitch axis is parallel to ground, transmission gear wheel R1 is fixed on azimuth axis, and the axis coinciding of gear centre and azimuth axis, azimuth axis is arranged on pedestal, it can rotate relative to pedestal, and stepper motor M1 rotates and transmission gear wheel R1 can be driven to rotate the large torque of generation.Transmission gear wheel R2 is fixed on pitch axis, and stepper motor M2 engages with gear wheel R2, and pitch axis is connected on the turning axle of photovoltaic array, and when the scope that photovoltaic array rotates exceedes preset range, stop following the tracks of, control position switch automatically resets.
