Daily life water, meanwhile, the service data of system is carried out using field terminal unit and remote monitoring system real
When collection, analysis and storage etc..This cogeneration system can maximize the comprehensive utilization ratio of solar energy, low to developing
Cost, high performance novel concentrator device are significant in condensation photovoltaic application.Generated electricity using solar energy highly effective low cost
It is current important research topic, and optically focused can improve solar radiation density and reduce the use of expensive photovoltaic cell, drop
Low system cost.In following 10 to 20 years, new energy is coexistence and co-prosperity, integration and cooperation in most of occasions with traditional fossil energy
Relation.Cogeneration research project under reflection-type slot light collection and photovoltaic are integrated, can solar tracking, adjustable, high due to possessing
The comprehensive advantages such as transformation efficiency, will be in roof distributed energy, high-efficiency photovoltaic power station, outlying oilfield producing well electricity saving and energy saving, day
Right gas is widely used with fields such as solar association circulating generations.Particularly existing illumination resource I, II class at home
Area, it is contemplated that the emerging market of 10,000,000,000 yuan of a mistake can be createed.
But the sun tracker effect design used in the prior art is bad, cosine shadow effect is easily produced, is reduced
While generating, photovoltaic cell is caused to be changed into the deficiency of ohmic load.
The content of the invention
For problems of the prior art, it is an object of the invention to provide a kind of reflection-type slot light collection thermoelectricity connection
For system, the system preferably solves conventional reflective-type by azimuth and the two-dimensional tracking system of elevation angle control simultaneously
For cogeneration system because technological deficiency caused by shadow effect, generating, heating effect more optimize, design is simple, easy to maintenance.
To achieve the above object, the present invention provides a kind of reflection-type slot light collection cogeneration system, including multigroup optically focused
Device unit and water cooling recovery system；
Every group of concentrator unit includes：Mounting system, dual drive system, speculum group and battery component string；
As a kind of for example, the speculum group is one kind of concentrator；
As one kind for example, the battery component string is IBC photovoltaic module structures；
Further, the mounting system includes：Mirror support and battery bracket, the speculum group are fixedly mounted on
On mirror support, the battery component string is arranged on battery bracket, it is ensured that the near focal point of speculum group is fixed on, and

Further, the dual drive system includes：One elevation drive for being responsible for angle of pitch rotation, another
It is responsible for the azimuth device of rotation driving of whole integrative-structure, automatic tracking system and electric-control system；
The mentality of designing of the automatic tracking system is as follows：
Firstth, cogeneration system remains poly- in real time mainly by automatic tracking system to sun real-time tracing
The primary optical axis of light device is parallel with the incident ray of sunshine；
The tracking mode of traditional trough system belongs to one-dimensional tracking, and parabola is typically put according to its focal line by positive North and South direction
Put, condenser only collects direct projection light, it is necessary to the angle of pitch of speculum is adjusted using tracks of device and corresponding control system,
This is just readily formed cosine shadow effect, reduces generating and the heating effect of photovoltaic panel；
Secondth, the development of automatic tracking system of the present invention is significantly improved, and is attained by the angle of pitch and azimuth
Tracer request, compared with traditional one-dimensional tracking mode, the shade shadow that cosine effect is brought can be completely eliminated in two-dimensional tracking
Ring, because in the case of one-dimensional tracking, the sun is oblique direct projection on speculum, inevitably produces shade drawback, sooner or later
When shaded area it is maximum, shaded area when noon is minimum, and the influence caused by this shade is not simple
Reduce the generated energy of several photovoltaic panels, photovoltaic panel is equivalent to load under shade, and it is not only without generation electric energy, but also disappear
Electricity caused by other photovoltaic panels is consumed, generating efficiency is had a greatly reduced quality, so two-dimensional tracking inherently eliminates this negative effect；
3rd, the setting of trace routine：
1. concentrator uses two-dimensional tracking system real-time tracing running track from sun, tracking system enables concentrator to protect all the time
Hold vertical with sunshine, it is possible to more solar energy are collected in limited usable floor area；Theory analysis shows, the sun with
Track and non-tracking, the acceptance rate difference 37.7% of energy, the accurate sun that tracks is even more the sun that can greatly improve concentrator
Energy acceptance rate, and then the whole efficiency of system is improved, so selection one tracks accurately Trajectory Arithmetic and high-precision equipment
Generating and Heat-collecting effect to concentrating component play vital effect；
2. in the prior art, realize that the automatic tracking sun has two ways, i.e. photovoltaic and mechanical system；The former because
Influenceed by weather condition, there is suitable limitation, that is to say, that, it is difficult to reach round-the-clock use.The latter can be divided into red again
Road ceremony and azimuth-elevation formula, equator ceremony are after by the installation of the latitude-tilt of locality, as long as the rotary speed along the equatorial plane
It can keep 1 week/24 hours, but accurately achieve 1 week/24 hours easy things by no means, even if accomplishing, the tune of solar declination
Section still needs to manual operations, so not reaching full automatic requirement still actually；The supporting construction of equatorial is for large-scale heavy simultaneously
Carry and put relatively difficult to achieve, the technical characteristic of unsuitable slot type tracking；
We is invented using so-called azimuth-elevation formula system, and the position of sun by any one day any moment is its orientation and faced upward
Angle is calculated by program, further calculates the sun angle of local longitude and latitude, is most accurate automatic tracking mode；Base
It is written " in the books of Astronomical Formulae for Calculators " one in Polish women scientists Jean Meeus
Computational methods, atmospheric refraction calculation formula is additionally used when elevation angle is very low in the morning elevation angle is corrected, be current text
Contained precision highest position of sun computational methods, its theoretical calculation precision can reach 0.052mrad in offering；
3. the system employ the algorithm add obliquity sensor composition a closed loop feedback system, carry out accurately with
Track is controlled, and system is detected in real time by obliquity sensor to the angle of concentrator, and obliquity sensor has to running position to stop
Electric memory function, the movement position of device can be reflected in real time；After system starts, theory that system will be calculated in operation
The actual corners angle value that value and sensor collect is compared, ensure tracking and driving system deviation control ± 0.1 degree with
It is interior, judge the traffic direction of concentrator according to obtained difference is positive and negative；
4. it is sun altitude and azimuthal change corresponding to hardware configuration motion in elevation angle-Bearings tracking mode
Change, using the horizontal system of coordinates, one of axis of heliostat turns into azimuth axis, in addition an axle and side perpendicular to ground
Position axle is vertical, referred to as pitch axis.During the sun is tracked, heliostat is transported according to the change of sun altitude around pitch axis
It is dynamic, change the inclination angle of heliostat with this；Changed according to the change of solar azimuth around azimuth axis, track the azimuth of the sun,
Heliostat normal purpose parallel with sunray all the time can thus be reached in theory, this design tracking accuracy is high,
And the weight center of heliostat, by the plane where vertical axis, hardware design is simple, and investment is less；
As a kind of for example, not only considering track algorithm realization, sensor data acquisition and equipment state in program
Monitoring etc., it is also contemplated that the danger of various cases of emergency is evaded, such as strong wind and heavy rain, temperature, flow and pressure anomaly etc.；
The electronic control is as follows：
Firstth, the steady ordered operation of each executing agency is be unable to do without under the upload of effective data and instruction of electric-control system
Reach；
Secondth, described electric-control system core component is programmable logic controller (PLC) PLC, and it is automatic following control system
