Description
Technical field
The present invention relates to the solar energy power generating field, relate in particular to novel flat single-axis solar tracking system and antitracking method.
Background technology
Solar tracking system is in photo-thermal and the photovoltaic generation process, and optimization sun power uses, and reaches the machinery and the ECU (Electrical Control Unit) system that improve photoelectric transformation efficiency.In the solar energy tracking process, if keep solar panel at any time over against the sun, allow the light propulsion system of vertical irradiation solar panel at any time of sunshine, the generating efficiency of solar photovoltaic assembly will greatly improve so.But simultaneously, solar panel always keeps the sunshine vertical incidence if leave, when angle of incidence of sunlight hour, such as sooner or later constantly, the part of solar panel can more be blocked near the cell panel of sun incident direction by adjacent, because cell piece is cascaded structure in the solar panel, and the crystal silicon battery plate is semiconductor material, resistance is very not large when having solar radiation, and therefore when the part cell panel was blocked, the overall generated energy of cell panel can reduce greatly.
In order to allow solar panel hour avoid the shade between the adjacent cell plate to block at the angle of incidence of sunlight degree, need to carry out antitracking to sun power.Present existing single-axis solar antitracking method is: after the angle of dependence angle of incidence of sunlight, the size of tracker and the parameters such as installing space size between the tracker array are carried out accurate Calculation, then draw best antitracking angle.
When according to above-mentioned antitracking method sun power being carried out antitracking, there is following problem: (1) different infields, because the longitude and latitude difference causes the parameters such as angle, the spacing dimension between the tracker array, tracker size dimension and setting height(from bottom) of angle of incidence of sunlight not identical, therefore existing antitracking operational factor can not be same local the use; (2) this antitracking method needs a large amount of parameter computings, therefore ability and the capacity of the compute chip of controller all will be strengthened and increase, and has greatly improved the cost of system; (3) present construction precision and installation accuracy are difficult to satisfy the accuracy requirement of existing antitracking computing, thus all added penalty coefficient in the antitracking operational method at present, and so just greatly reduce power benefit.

S305, as shown in Figure 5, when sun climbed, solar irradiation is mapped to No. one and No. two trackers in the east during the lower induction point of sensor, and all trackers begin slowly to rotate eastwards.
S306, as shown in Figure 6, when No. one and No. two trackers when the upper induction point of sensor is not subject to solar irradiation in the east, all trackers stop the rotation.
S307, constantly repeat S305 and S306, until the angle of Solar panel backside and ground level is 60 when spending (60 degree angles are setting value, are the rotation extreme angles of tracker), as shown in Figure 7, antitracking campaign is end all.
Before the sun sunset sun power is carried out normal pursuit movement, Solar panel backside keeps vertical with the sunshine incident ray in this process, and the light intensity that whole trackers receive is identical.
The sun at sunset, the work of antitracking campaign and stop upper and lower induction point by the west sensor of No. two and No. three solar tracking devices whether to be subject to solar irradiation be criterion.May further comprise the steps the antitracking of sun power this moment:
S401, whole trackers westwards rotate.
Start the two states of antitracking before S402, the sun sunset, as long as reach wherein a kind of state, just start the front antitracking campaign of sun sunset;
State one: the spacing between the solar tracking device is smaller, the angle of Solar panel backside and ground level does not also reach 60 degree, and (60 degree angles are setting value, rotation extreme angles for tracker) time, upper and lower induction point on No. two and No. three tracker west sensors is just blocked by shade, and the upper and lower induction point on tracker west sensor is not blocked, and so all solar tracking devices stop the rotation;
State two: the gap ratio between the solar tracking device is larger, and when the angle on Solar panel backside and ground is 60 when spending when (60 degree angles are setting value, are the rotation extreme angles of tracker), as shown in Figure 8, all trackers stop the rotation;
S403, all be subject to illumination when the upper and lower induction point of a tracker west sensor, and the upper and lower induction point of No. two and No. three tracker west sensors is not when all being subject to solar irradiation, all slowly rotations eastwards of solar tracking devices; When the upper and lower induction point of No. two and No. three tracker west sensors all is subject to solar irradiation, as shown in Figure 9, whole tracker stop motions.
S404, slowly descend when the sun, the lower induction point that at first is No. two and No. three tracker west sensors is blocked by shade, when the sun continues slowly to descend, then is that the upper induction point of No. two and No. three tracker west sensors is blocked by shade, as shown in figure 10, whole trackers rotates eastwards.
S405, then constantly repeat S403 and S404, until the surface of solar panel when parallel with ground level the antitracking campaign all finish, namely get back at sunrise initial state.
