Description
Technical field
The invention belongs to the research fields of photovoltaic power generation, and in particular to a kind of double-axis tracking formula photovoltaic power generation apparatus.
Background technique
Solar energy power generating is to be formed by array by using solar photovoltaic assembly to receive incident sunlight, is passed through
Photovoltaic panel conversion converts light energy into electric energy, and electric energy caused by collecting is for the technology that uses.The technology have it is pollution-free,
At low cost, the sustainable advantage of power generation, and the strong torrid zone or desert area of illumination in all parts of the world has more and more
With.
It, generally can (or building roof etc. directly receives illumination on open ground currently, in solar photovoltaic generation system
Surface) on dispose a large amount of photovoltaic module rack, photovoltaic module panel is installed in rack, by photovoltaic module panel receive too
Sunlight irradiation carries out photovoltaic conversion power generation.Generally, according to the area of deployment region, the number of rack can be more than ten groups, tens
Group, up to a hundred groups even thousands of groups.
Meanwhile in order to preferably make photovoltaic module receive solar irradiation, photovoltaic module is had been realized in too in this field
Positive tracking system.By tracking solar motion in real time, the direction of photovoltaic module rack is adjusted, so that sunlight is directed to light
The light plane for lying prostrate component can increase the solar radiation quantity that photovoltaic module can receive, and improve solar energy power generating system
The overall power generation amount of system.
In simple terms, the realization principle of photovoltaic power generation apparatus automatic tracking system is to be mounted on tracking transducer to carry
In the rack of photovoltaic module.When radiation direction changes, then tracking transducer output offset signal, tracking system start to transport
Make, adjust the direction of the photovoltaic module in rack, until tracking transducer again reach equilibrium state (i.e. by photovoltaic module by
Optical plane with incident sunray at right angle when) stop operating, complete primary adjustment.So constantly adjustment can be true in real time
It protects photovoltaic array component and tracks the sun along the running track moment of the sun, improve total power generation.Automatic tracking system has hand
Dynamic control switch, to facilitate debugging.
Traditional photovoltaic power generation apparatus autotrack mode generally comprises: single shaft automatically tracks, step-by-step movement automatically tracks, double
Axis tracking etc..But currently, the control mode of these tracking mode whole realizations " one frame of a machine ", i.e., controlled and driven using single
System controls single photovoltaic module rack.If then being needed and photovoltaic module machine for the extensive laying on area in blocks
The same number of control of frame and drive system are unfavorable for photovoltaic power generation and exist which greatly increases being laid with cost and being laid with difficulty
The extensive utilization of economically less developed region.Therefore, it is necessary to the centralization tracking control systems to multiple photovoltaic module racks.
Meanwhile for current photovoltaic module rack, wind-proof performance is also an important investigation factor.China south
The more illumination in portion area and typhoon, will receive all directions when photovoltaic module rack is exposed in strong wind carrys out wind.Carrying out wind can be right
Rack generates pressure laterally and longitudinally.This proposes very high requirement to the wind resistance of rack.If askew by wind, photovoltaic module
The weight of itself is just sufficient to make the center of entire frame structure to shift, and then collapses.Therefore a kind of wind resistance is needed
Good photovoltaic module rack.
In addition, traditional photovoltaic generating system is very big to area requirements, just needed largely if building large-scale power station
Soil, this is easy for that land resource is caused to lack, and cost of electricity-generating also greatly improves.Therefore it needs a kind of to send out solar energy
Electricity, modern agriculture, nursery stock, medicinal material plantation, tourism, science and education effectively combine, a ground is mostly used, promote to get agricultural profit, reduce power generation at
This, promotes the electricity generation system of land resources science efficiency.
In summary, field of photovoltaic power generation lacks one kind to the progress centralization tracking control of multiple photovoltaic module racks at present
System, with good wind loading rating, can in various landform large area be laid with, photovoltaic power generation and agricultural planting can be made effectively to combine
Photovoltaic module tracking system.
