Embodiment 1
[0039] Example 1: Taking Nanjing as an example on July 8, 2016, based on the geographical location information of a photovoltaic power station, the local solar trajectory is generated as follows: figure 1 shown. figure 1 It is a map of the sun's trajectory at an altitude of 10 meters in Nanjing City (longitude 118.81°, latitude 32.04°) on that day. The picture is generated by the professional photovoltaic design software PVSYST, using the precise data of the Meteonorm meteorological satellite, and the orbit of the sun can also be obtained by other methods. The tracking method includes the following steps:
[0040] S101. Acquire the real-time altitude angle of the sun at 75.3° at the initial stage of the period T (set to 10 minutes in this embodiment);
[0041] S102. Obtain an initial adjustment target angle of 14.7°;
[0042] S103. Measure the current angle of the double-sided photovoltaic cell assembly as 12.5°, compare it with the initial adjustment target angle, convert ...
Embodiment 2
[0048] Embodiment 2: Taking Nanjing as an example on July 8, 2016 (carrying out a photovoltaic power generation test of the same scale at the same time and adjacent position as in Implementation 1), 36 groups of fixed light intensity sensors were set on the single-axis tracking bracket, and 36 groups The light intensity sensors are evenly arranged in a ring shape (so the adjustment accuracy is 5°, and it belongs to the single-axis tracking method). The tracking method includes the following steps:
[0049] S201, 36 groups of light intensity sensors simultaneously measure the light intensity value and calculate the integral of the light intensity value over time in a fixed period T (set to 10 minutes in this embodiment), and the two light intensity sensors of each group in the period T Integral value summation S i , S i Indicates the sum of the integral values of the two light intensity sensors of the i-th group;
[0050] S202. After the period T is over, determine S 1 , S...
Embodiment 3
[0058] Embodiment 3: A tracking controller for double-sided photovoltaic cell modules based on intelligent control, written in the control method of Embodiment 1 or 2.
