Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
One, concrete structure of the present utility model is described below:
Referring to Fig. 1-Fig. 3, the utility model comprises some photovoltaic modulies that are arranged in array 2, at every group of photovoltaic module 2Be equipped with the first reflector 1, the first reflector 1 above and be rotationally connected with the support 3 of photovoltaic module 2, also comprise for induction tooThe photoelectric sensor of sunlight line irradiating angle and the driving mechanism for the first reflector 1 is adjusted with sun irradiation angle, lightElectric transducer is connected with controller by circuit, and controller is connected with driving mechanism.

Can also be wherein to lay one deck white stone on the ground between adjacent two row's photovoltaic modulies 2, utilize unrestrained anti-The principle of penetrating, makes photovoltaic module 2 surfaces within the unit interval, receive more irradiation.
In native system when design,, the size of the first reflector, the second reflector, need to consider the spacing of front and rear row, left and right itBetween distance, choose reasonable.
Two, the principle of the utility model control system is as follows:
Wherein the principle of having utilized existing photovoltaic tracking system for the adjusting of the first angle of reflector, photovoltaic tracking systemThe principle of system is: solar photovoltaic array automatic tracking system, by real-time tracking solar motion, makes sunshine direct light photovoltaic array,Thereby increase the solar radiation quantity that photovoltaic array receives, improve the overall generated energy of solar energy photovoltic power system. Use extensivelyHave four kinds of solar photovoltaic automatic tracking systems, comprise horizontal uniaxiality tracking, the oblique uniaxiality tracking of two column, vertical uniaxiality tracking andDouble-axis tracking, wherein horizontal uniaxiality tracking only has a rotary freedom with inclined single-shaft tracking, vertical uniaxiality tracking, and twin shaft is followedTrack has two rotary freedoms.
The operation principle of photovoltaic tracking system is that installation of sensors is on solar cell array, with its synchronous operation. LightOnce trickle change occurs direction, sensor is unbalance, and system output signal produces deviation, in the time that deviation reaches certain amplitude,Sensor output corresponding signal, executing agency starts to rectify a deviation, and makes photoelectric sensor again reach balance--by sensorWhen the solar cell array plane of output signal control and light angulation, stop operating, complete adjustment cycle one time. So constantlyAdjust, the moment is followed the sun along the running orbit of the sun, forms a closed-loop feedback system, realizes from motion tracking. This systemDo not need to set reference position, sensor is never got lost. This system be provided with that preventing stray light disturbs and night tracking circuit, and haveHand control switch, to facilitate debugging. The utility model utilizes the operation principle of photovoltaic tracking system to realize the angle of reflectorAutomatically adjust with sun irradiation angle.
Three, current, the shortcoming of photovoltaic generation tracking system is both at home and abroad:
Photovoltaic generation tracking system drops into larger, generally, flat single-shaft tracking system drop into increase 0.5-1 unit/watt;Tiltedly single-shaft tracking system input increase 1-1.5 unit/watt; Dual-axis tracking system input increase 2.5-3 unit/watt. If system is normalOperation, generating gain can remain basically stable with dropping into increase, but according to use experience in the past, tracking system fault rate is higher, noEasily cost-recovering, investment risk is larger.
Native system when design, compare conventional power plant except considering the distance between front and rear row, also to consider left and right itBetween distance, avoid shade to block, cause floor space very large.
The relation of different tracking systems and cost, generated energy gain, floor space and risk is as table 1
Table 1
According to upper table, can select suitable tracking system for the utility model, be convenient to can adjust constantly reflectorAngle, strengthen the light income on photovoltaic module surface, with lower cost, improve generated energy.
When the utility model is implemented, respectively white reflection plate is positioned over to the support rear side in first row power station, and second rowThe oblique rear of power station assembly, white stone is laid in the vacant lot in the middle of two row power stations, utilizes the software setting according to seasonal effectSun altitude situation of change, lasting automatic control angle of reflector, reflexes to assembly surface by sunshine.
Four, by inference mode, advantage of the present utility model is described in detail below:
Sun altitude=90 °-(latitude of local latitude ± subsolar point) is such as (1) Beijing (40 ° of N) summer solstice(23 ° of 26 ' N) height of the sun at noon aa=90 °-(40 °-23 ° 26 ')=73 ° 26 '
According to calculate can draw reflector install angle be 84 ° 23 ';
(2) height of the sun at noon aa=90 ° of Beijing (40 ° of N) winter solstice (23 ° of 26 ' N)-(40 °+23 ° 26 ')=26 ° 34 '
According to calculate can draw reflector install angle be 115 ° 37 ';
Angle of reflector is by controller, from 84 ° 23 ' to 115 ° 37 ' evenly automatically regulate, regulate every year a circulation,According to ray cast principle, suppose that reflector reflectivity is α, calculate and can show that the irradiation of assembly surface increase is strong by theoryDegree (being generated energy gain) is:
Summer solstice generated energy gain ≈ 0.41 × α × 100%
Winter solstice generated energy gain ≈ 0.67 × α × 100%
Set up in this way the contrast power station of two 2KW, one of them power station adopts catoptric system, the reflection of reflectorRate 70%, the gain of theoretical calculating generated energy should be 0.67 × 0.7 × 100%=46.9%. Only consider the altitude of the sun at high noon hereinAngle. In actual conditions, variation is not being stopped at the sun altitude of every day and azimuth, and the light that is reflected in assembly surface also canThe inhomogeneous current mismatch loss that causes generating gain part. In reality, be difficult to find suitable reflector size and angleControl realizes assembly surface whole day by total reflection uniformly. So use diffuse-reflective material in practical application, generated energy gains alsoShould be as the criterion with actual measurement data.
9 days generated energy data of actual measurement are as shown in table 2:
Remarks: upper showing as measured data, wherein December 8, December 9,12 during 2015.12.04-2015.12.16The moon 13, four days on the 14th December are that serious haze weather generated energy is very little, and the tracking accuracy of ammeter is 0.1kWh, calculatesGenerated energy gain error is larger, so remove in tables of data.
Experimental session, catoptric system generated energy is higher by 9.25% than conventional system, and generated energy gain is directly proportional to irradiation intensityRelation, irradiation intensity is larger, and generated energy gain is more obvious. Concrete generated energy gain ratio is between 2.44%-16%, and figure below isThe generated energy gain of experimental session every day and the relation of odd-numbered day irradiation. When irradiation is lower, corresponding irradiation intensity on the same day is little,In environment, scattered light accounting example is higher, so the gain of catoptric system generated energy is less. On the contrary, when irradiation is higher, the corresponding same dayIrradiation intensity is large, and in environment, direct light accounting example is higher, so the gain of catoptric system additional issue electric weight is larger.
The relation of generated energy gain and amount of radiation as shown in Figure 4.
Five, advantage of the present utility model
The utility model is the adjustable reflector of setting angle on existing photovoltaic module on the one hand, utilizes photoelectricityThe variation of the different period sun altitudes of sensor sensing, makes the automatic adjusting angle of reflector, realizes photovoltaic module aroundLight reflection is to photovoltaic module surface, thereby effectively increases the irradiation of assembly surface, the generating that finally improves photovoltaic systemAmount, reduction degree electricity cost; That the ground surface of arranging between assemblies at the back side and two at photovoltaic module front row increases reflective on the other handPlate or lay white stone, reflexes to assembly surface again by the light of reflector reflection above, also has part directly simultaneouslyReflex to assembly surface. The mutual reflection of the utility model utilization has comprised mirror-reflection and diffuse reflection, makes photovoltaic module surfaceWithin the unit interval, receive more irradiation, improve single watt of generated energy of photovoltaic generating system, thereby improve photovoltaic generationThe generated energy income of system, reduction degree electricity cost.
