Solar energy is a clean and pollution-free renewable energy source, and a photovoltaic module is a module for generating electricity based on solar energy and is a power generation device which can generate direct current after being exposed to sunlight. Since the solar altitude is changed with time, in order to obtain the optimal power generation efficiency of the photovoltaic electric field formed by the photovoltaic module, the photovoltaic module needs to be placed on a fixed and adjustable photovoltaic support so as to adjust the angle with the solar altitude. At present, the angle adjustment date of the fixed adjustable photovoltaic support and the adjustment angle each time are fixed, the adjustment is generally carried out four times a year, a certain angle is adjusted each time, when the adjustment times are changed, even if the optimal inclination angle of the support can be obtained through calculation, the current means is difficult to accurately and quickly obtain the angle adjustment date each time, and the optimal power generation efficiency of a photovoltaic electric field cannot be ensured.

and determining feasibility of the angle adjustment date in the preset date section by combining the operation resources and the operation environment.
According to the method for determining the fixed adjustable photovoltaic support angle adjustment date, an adjustment period set including at least one adjustment period in a preset date segment is established, whether the difference value between the number of the adjustment periods in the current adjustment period set and the obtained adjustment times in the preset date segment is larger than 0 is judged, when the difference value is larger than 0, a first adjustment period and a second adjustment period of adjacent dates are combined into one adjustment period from the adjustment period set every time until the difference value between the number of the adjustment periods in the adjustment period set and the adjustment times is not larger than 0; and when the difference is not greater than 0, determining the angle adjustment date in the preset date section according to the obtained adjustment period set. The method can realize the quick and accurate acquisition of the angle adjustment date every time, ensures the optimal power generation efficiency of the photovoltaic electric field, and is convenient for the daily maintenance of the photovoltaic electric field.
The embodiment of the invention also provides a method for determining the angle adjustment date of the fixed adjustable photovoltaic support, a flow chart of which is shown in fig. 2, and the method for determining the angle adjustment date of the fixed adjustable photovoltaic support comprises the following steps:
step 201: and acquiring the adjustment times in the preset date field.
The preset date section represents the time length to be researched, is recorded by year, month and day, and is correspondingly provided with an opening date and an ending date.
For example, the time length of the preset date segment may be one year, and the number of times of adjustment may be 4 from 1/2019 to 31/2019/12/2019.
Step 202: an adjustment period set including at least one adjustment period within a preset date period is established.
Wherein each adjusting period comprises at least one daily data item, an adjusting angle in the period and generating efficiency in the period.
It will be understood by those skilled in the art that the unit of the preset date field is a day, that is, the preset date field comprises a plurality of days. For the adjustment period set in the preset date segment, the number of days included in the adjustment period may be limited according to actual needs, and the adjustment period may be limited to one day, two days, one week, or ten days, etc.
In establishing the set of adjustment periods within the preset date period, the number of days of each adjustment period may be the same, for example, one day. Since the adjustment cycle is a period of time, each adjustment cycle also has a start date and an end date.
For each adjustment period, each adjustment period includes at least one daily data item, wherein the daily data item includes a time date (year/month/day), a rack optimum inclination angle, and an actual power generation efficiency. The optimal inclination angle of the bracket refers to that when the day bracket is arranged at a certain fixed angle, the photovoltaic module has the optimal power generation efficiency under the fixed angle, the optimal inclination angle of the bracket can take-20 degrees as an initial value, and can be circularly input in a calculation program of the known optimal inclination angle of the bracket in a slightly increasing mode (for example, 0.1 degree is increased every time) in an angle range of-20 to 90 degrees, and the inclination angle with the maximum power generation amount is selected as the optimal inclination angle of the bracket; the actual power generation efficiency refers to the actual power generation efficiency of the photovoltaic module at the actual support inclination angle, and the actual power generation efficiency can be obtained through calculation of the actual support inclination angle.
Each adjustment cycle further includes an intra-cycle adjustment angle, and the intra-cycle adjustment angle may also obtain the optimal tilt angle of the stent within the days included in the adjustment cycle according to the above-mentioned calculation method of the optimal tilt angle of the stent, and set all the angles of each day in the adjustment cycle to be the same, that is, the tilt angles of each day in the adjustment cycle are the same.
Each adjustment cycle further includes an intra-cycle power generation efficiency, and the intra-cycle power generation efficiency of each adjustment cycle is computationally a sum of power generation efficiencies at the adjustment angle within the cycle for each day within the cycle.
Step 203: and correcting the optimal inclination angle of the support in the daily data item to obtain the corrected optimal inclination angle of the support.
The technical personnel in the field can understand that in the actual engineering, due to consideration of comprehensive factors such as occupied land, the inclination angle of the bracket cannot be set at will, the angle of the inclination angle of the bracket needs to be limited, and the optimal inclination angle of the bracket beyond the limited angle range is corrected to meet the actual erection requirement.
Step 204: and arranging each adjusting period in the adjusting period set according to the time sequence to form an adjusting period set of adjacent dates.
After the adjustment period set is established, each adjustment period in the adjustment period set is not necessarily arranged according to a time sequence, and may be arranged in a random sequence.
Step 205: and judging whether the difference value between the number of the adjustment periods in the current adjustment period set and the adjustment times is greater than 0.
It can be understood by those skilled in the art that if the difference between the number of adjustment cycles in the current adjustment cycle set and the adjustment times is greater than 0, it indicates that the number of adjustment cycles in the current adjustment cycle set is greater than the adjustment times, and the number of adjustment cycles in the current adjustment cycle set needs to be reduced, and specifically, the number of adjustment cycles can be reduced in a form of being combined with each other, see the description in step 206; if the difference between the number of adjustment cycles in the combination of the current adjustment cycles and the adjustment times is not greater than 0, that is, the number of adjustment cycles in the current adjustment cycle set is equal to the adjustment times, then the angle adjustment date in the preset time period can be determined according to the start date and the end date of each adjustment cycle in the current adjustment cycle set, as described in step 207.
Step 206: when the difference between the number of the adjustment cycles in the adjustment cycle set and the adjustment times is larger than 0, combining the first adjustment cycle and the second adjustment cycle of adjacent dates into one adjustment cycle from the adjustment cycle set each time until the difference between the number of the adjustment cycles in the adjustment cycle set and the adjustment times is not larger than 0.
The power generation loss efficiency after the combination of the first adjustment period and the second adjustment period is the minimum value of the power generation loss efficiency after the combination of the adjustment periods of any two adjacent dates in the adjustment period set, and the power generation loss efficiency is the difference between the sum of the power generation efficiency in the adjustment periods of the two adjacent dates and the power generation efficiency of the adjustment period after the combination of the adjustment periods of the two adjacent dates.
As will be understood by those skilled in the art, on one hand, since each adjustment cycle in the adjustment cycle set is arranged in time sequence, when the adjustment of the number of adjustment cycles in the adjustment cycle set is performed, the adjustment is performed by merging the adjustment cycles of two adjacent dates; on the other hand, when it is determined that the difference between the number of adjustment cycles in the adjustment cycle set and the adjustment times is greater than 0, it is necessary to adjust several or more adjustment cycles in the adjustment cycle set, and the number of days included in each adjustment cycle in the adjustment cycle set is no longer the same.
In order to obtain the first adjustment period and the second adjustment period, a loop operation is required in this step, the adjustment periods of all two adjacent dates in the adjustment period set are combined, and the power generation loss efficiencies of all the combined adjustment periods are compared to obtain the first adjustment period and the second adjustment period before combination with the minimum power generation loss efficiency.
In addition, when a plurality of or a plurality of adjustment cycles are adjusted in a combined manner, the adjustment angle in the corresponding cycle is also changed, so that the power generation efficiency of the adjustment cycle in which the adjustment cycles on two adjacent dates are combined is different from the sum of the power generation efficiencies of the adjustment cycles on two adjacent dates before the combination in the respective cycles.
For example, the first adjustment period is 1/2019, and the second adjustment period is 1/2/2019, then the adjustment period after the first adjustment period and the second adjustment period are combined is 1/2/2019, and since the combined adjustment period changes in duration and the adjustment angle within the period, the difference between the power generation efficiency of the two adjustment periods, i.e., 1/2019 and 1/2/2019, and the power generation efficiency of the adjustment period, i.e., 1/2/2019, is the minimum value of the difference between the power generation efficiency of the adjustment period of any two adjacent dates in 2019 and the power generation efficiency of the adjustment period after the adjustment periods of the two adjacent dates are combined.
Step 207: and when the difference value between the number of the adjustment periods in the adjustment period set and the adjustment times is not more than 0, determining the angle adjustment date in the preset date field according to the obtained adjustment period set.
In one possible implementation, as shown in fig. 3, determining the adjustment angle date within the preset period segment according to the combination of the obtained adjustment periods includes:
step 2071: and acquiring the starting date and the ending date of each adjusting period in the set according to the obtained adjusting period set.
Since the set of adjustment periods obtained includes adjustment periods of the number of adjustment times, and each adjustment period includes a start date and an end date, the start date and the end date of each adjustment period in the set can be acquired.
For example, the obtained set of adjustment periods includes 4 adjustment periods, and the start date and the end date of the first adjustment period may be: 1/2019 and 21/2019 and 3/2019; the start date and the end date of the second adjustment period may be: 22 months 3 and 8 months 4 and 2019; the start date and the end date of the third adjustment period may be: 9/4/2019 and 7/9/2019; the start date and the end date of the fourth adjustment period may be 2019, month 9, day 8 and 2019, month 12, day 31, respectively.
Step 2072: and determining the angle adjustment date in the preset date field according to the starting date and the ending date.
And determining the adjustment angle date in the preset date field according to the starting date and the ending date of each adjustment period in the set.
Taking the example in step 2071 as an example, the angle adjustment dates in the preset date segment from 1/2019 to 31/2019/12/2019 may be 21/2019/3/4/8/2019/9/7/2019.
Step 208: and determining feasibility of the angle adjustment date in the preset date section by combining operation resources and an operation environment.
Due to limitations of operating resources and operating environments, for example, a plum rain period exists in a preset date period, and the sunlight irradiation intensity is weak, feasibility determination needs to be performed on the angle adjustment date according to actual conditions, whether the determined angle adjustment date is reasonable or not is evaluated, and if the determined angle adjustment date is not reasonable, correction or recalculation needs to be performed on the determined angle adjustment date.
The skilled person can understand that the method for determining the angle adjustment date of the fixed and adjustable photovoltaic support can be applied to the design of a new fixed and adjustable photovoltaic electric field support, and the calculated angle adjustment date can assist in making an engineering design scheme, and can also be applied to a fixed and adjustable support which is already built and put into operation to help a design engineer to perform operation and maintenance on the fixed and adjustable support.
