In the embodiment of the present application, in the power supply, solar energy is used as a clean energy source to generate electricity for example, and other situations, such as wind power generation, are similar to the clean energy source, and will not be described in detail.
The process flow shown in fig. 1 will be described in detail with reference to the specific embodiments, and the following may be included:
In an implementation, the centralized control terminal captures real-time generated power of the plurality of solar panels in real time through a plurality of power detection sensors mounted on the plurality of solar panels.
And 102, comparing the real-time generated power with a preset standard power, and calculating and generating real-time supplementary power.
In the implementation, the centralized control terminal gathers a plurality of real-time power generation powers to generate total power generated by a plurality of solar panels, and then the centralized control terminal calculates and generates real-time supplementary power by the difference between the total power and the standard vertebral power.
And step 103, adjusting the current working gear of the diesel generator and the output power or the charging power of the storage battery according to the real-time supplementary power.
In the implementation, the centralized control terminal stores the power generated by the diesel generator in each working gear, and the diesel generator and the storage battery are provided with power detection sensors for detecting output or input power.
After the centralized control terminal generates the real-time supplementary power, the working gear of the diesel generator closest to the real-time supplementary power is matched, and further, the total electric power output by the solar panels and the diesel generator is supplemented in a storage battery charging or discharging mode, so that the total electric power output by the solar panels, the diesel generator and the storage battery is relatively stable.

step 201, generating a current capturing period corresponding to the current time based on the current time and a preset unit capturing duration, and calculating and generating average value complementary power according to a plurality of real-time complementary powers in the current capturing period.
In the implementation, the centralized control terminal firstly generates a current capturing period taking the current moment as a starting point by the current moment and the unit capturing time length, then the centralized control terminal counts a plurality of real-time supplementary powers in the current capturing period, and then the average value of the counted plurality of real-time supplementary powers generates average supplementary power.
It should be noted that, during the operation of the diesel generator, the plurality of solar panels and the storage battery, the average value of the above unit capturing period should be used to supplement power, so as to provide a reference for the power supply of the current unit capturing period, so as to adjust the working gear of the diesel generator in the current unit capturing period, and avoid the repeated adjustment of the working gear of the diesel generator, which makes the operation too complicated.
Step 202, adjusting the current working gear of the diesel generator and the output power or charging power of the storage battery based on the average supplementary power, the generated power of the diesel generator in a plurality of working gears and the current stored electric quantity of the storage battery.
In the implementation, the centralized control terminal supplements power by the average value in the last unit capturing period, matches the nearest diesel generator working gear, and then adjusts the total power output by the plurality of solar panels, the diesel generators and the storage battery through the storage battery charging and discharging so as to keep the stability of power supply. Meanwhile, the centralized control terminal can change the working gear of the diesel generator by the current stored electric quantity of the storage battery so as to maintain the stored electric quantity in the storage battery.
Optionally, in this application, the following processes may also exist, and specific operation flows are as follows:
capturing the storage electric quantity of the storage battery in real time;
and changing the working gear of the diesel generator based on the stored electric quantity, the preset capacitance bottom line and the preset capacitance top line.
In the implementation, the centralized control terminal captures the stored electric quantity stored by the storage battery in real time, and when the stored electric quantity of the storage battery is between the capacitance bottom line and the capacitance top line, the diesel generator works in a working gear capable of generating the most-similar average supplementary power.
When the storage electric quantity of the storage battery is smaller than the capacitance base line, if the total power output by the plurality of solar panels and the diesel generator under the current working gear is not larger than the standard power, the diesel generator is regulated to the adjacent other working gear, so that the storage battery is in a charging state; if the total power output by the solar panels and the diesel generator in the current working gear is larger than the standard power, the working gear of the diesel generator is not changed, and the storage battery is in a charging state.
When the storage electric quantity of the storage battery is larger than the capacitance top line, if the total power output by the plurality of solar panels and the diesel generator in the current working gear is not smaller than the standard power, the diesel generator is regulated to the adjacent other working gear, so that the storage battery is in a discharging state; if the total power output by the solar panels and the diesel generator in the current working gear is smaller than the standard power, the working gear of the diesel generator is not changed, and the storage battery is in a discharging state.
Optionally, solar panels in the same geographical location area carry the same address location identifier, and after step 101, there is a process as shown in fig. 3, and the specific operation flow is as follows:
In implementation, the centralized control terminal screens out a plurality of solar panels with the same geographic identification, so as to screen out a plurality of solar panels in an address location area, wherein the geographic identification can be called a target geographic identification, and the solar panels can be called designated solar panels.
And then the centralized control terminal captures the appointed real-time power generation power of each appointed solar panel energy in real time, and screens out the maximum power generation power in the appointed real-time power generation powers at each moment.
Step 302, the target maximum generated power and the rest of the specified real-time generated powers at the same time are compared one by one.
In implementation, the centralized control terminal further processes the specified real-time power generated by the specified solar panels at each moment, for example, selects one of the maximum power generated, where the maximum power may be referred to as a target maximum power generated, and then compares the target maximum power with the remaining specified real-time power generated one by one, so as to query the specified real-time power difference of different specified solar panels at the same moment.
And step 303, when the difference value between the target specified real-time power generation power and the maximum power generation power is larger than the preset power threshold in the capturing moment, marking the specified solar panel corresponding to the target specified real-time power generation power as a problem solar panel.
In implementation, at a certain moment, a certain moment may be referred to as a capturing moment, and when the difference between the target specified real-time generated power and the maximum generated power is greater than the power threshold, the centralized control terminal marks the specified solar panel corresponding to the target specified real-time generated power as the problem solar panel. The problem solar panel can be a solar panel damaged due to faults, a solar panel which receives sunlight due to shielding of leaves or other objects, or a solar panel which has an inclination angle which is not perpendicular to direct sunlight.
After the centralized control terminal marks the problem solar panel, the user can be reminded of timely checking the problem solar energy in a mode of displaying or sending the problem solar panel to the mobile terminal of the user through the display screen. It should be noted that the capture time is in one-to-one correspondence with the problem solar panel, and should be the time at which the given solar panel is marked as the problem solar panel. After the problem solar panel is maintained, the identification and capturing time of the solar panel should be eliminated.
Optionally, after step 303, there is also a process as shown in fig. 4, and a specific operation flow is as follows:
In implementation, the centralized control terminal calculates and generates a plurality of mutation time periods by taking a plurality of capturing moments as starting points and mutation time lengths, so that a user can conveniently detect the designated real-time power generation power change of a designated solar panel in the mutation time periods.
In implementation, the centralized control terminal counts the specified real-time power generated by the problem solar panel in a sudden change period corresponding to the problem solar panel, where the sudden change period may be referred to as a target sudden change period, and the specified real-time power generated by the problem solar panel may be referred to as a problem real-time power generated. And then the centralized control terminal generates a power variation from the difference value between the maximum value and the minimum value in the real-time generated power of the problems.
And step 403, marking the change of the problem solar panel as a fault solar panel if the power change is greater than a preset abrupt change threshold.
In the implementation, the centralized control terminal compares the power variation with the mutation threshold, and if the power variation is larger than the mutation threshold, the centralized control terminal marks the power problem solar panel change as a fault solar panel. Meanwhile, the centralized control terminal can also send the marked fault solar panel to a display screen or a mobile terminal of a user so as to prompt the user to timely process the solar panel with the fault.
And step 404, monitoring real-time power generated by the plurality of problem solar panels and the plurality of fault solar panels within a preset monitoring time period after the current moment.
In the implementation, in order to facilitate the identification of solar panels blocked by sunlight from the problem solar panels or the fault solar panels, the centralized control terminal monitors the real-time power generated by the plurality of problem solar panels and the plurality of fault solar panels within the monitoring time period after the current moment, when the difference between the real-time power generated by the problem solar panels or the fault solar panels and the maximum real-time power generated by all solar panels at the same moment is not greater than the power threshold, the problem solar panels or the fault solar panels are considered as solar panels blocked by sunlight.
The monitoring time length at this moment is in this application to take the unit of day, and monitoring time length is 1 day or 2 days for example, needs to avoid the influence of overcast and rainy day to the monitoring result simultaneously, and overcast and rainy weather information can derive from appointed network address, also can make the real-time power generation condition of feeding back by a plurality of rest non-problem solar panel, judges whether at present is in overcast and rainy weather.
In step 405, if the difference between the target real-time generated power and the maximum generated power is not greater than the power threshold in the problem solar panel or the failure solar panel, the problem solar panel or the failure solar panel is marked as a shading solar panel.
In an implementation, when the centralized control terminal captures a problem solar panel or a fault solar panel, a difference between a certain real-time generated power and a maximum generated power is not greater than a power threshold, the centralized control terminal marks the problem solar panel or the fault solar panel as a shading solar panel, and sends the shading solar panel to a display screen or a mobile terminal of a user, wherein the real-time generated power can be referred to as a target real-time generated power.
Optionally, after step 405, there is also a process as shown in fig. 5, and a specific operation flow is as follows:
In the implementation, after the centralized control terminal shades the solar panel at the mark, a plurality of adjustment periods are generated by the adjustment period and the current time, and then the centralized control terminal drives the shading solar panel to move according to a basic motion track in each adjustment period, wherein the basic motion track sequentially moves according to a spatial sequence from top to bottom, from left to right, clockwise rotation and the like.
The centralized control terminal controls the motor arranged on the shading solar panel to operate through a basic running track in a certain adjustment period, and simultaneously captures the maximum generated power output by the shading solar panel in the whole movement process in the movement process of the shading solar panel, wherein the generated power can be called peak generated power, and the adjustment period can be called target adjustment period.
In implementation, the centralized control terminal records the time median in the target adjustment period as the peak time and records the position of the corresponding shading solar panel as the peak position information, and it should be noted that the target adjustment period in the application may be any adjustment period.
And 504, counting peak time and corresponding peak position information in a plurality of adjustment periods within a preset monitoring time period after the current time, and generating an actual track movement diagram.

The overall movement duration in the actual movement trace diagram herein should be in days, for example, one day, two days, etc.
In the implementation, after the solar panel is generated by the centralized control terminal, the motor action installed on the shading solar panel is controlled by the actual track movement diagram within the same complete movement duration, so that the influence of vegetation or building shading sunlight on the solar panel power generation is reduced.
Optionally, in this application, the following processing manner also exists, and a specific operation flow is as follows:
when a specific adjustment period exists, the difference value between the peak output power and the minimum valley output power of the shading solar panel is smaller than the preset bottom line power value, and specific peak position information corresponding to the specific adjustment period is generated based on the peak position information in two adjacent adjustment periods.
In an implementation, when the centralized control terminal recognizes that the peak output power and the minimum valley output power of the shaded solar panel exist in a certain adjustment period, the difference value between the peak output power and the minimum valley output power of the shaded solar panel is smaller than a preset bottom line power value, and the adjustment period may be referred to as a specific adjustment period.
The centralized control terminal is matched with two adjustment periods closest to the specific adjustment period before the specific adjustment period, wherein the adjustment period is an adjacent adjustment period, and the centralized control terminal generates specific peak position information according to the same moving distance by peak position information peaks of the two adjacent adjustment periods. Therefore, the influence on the generation of the actual motion trail graph by the centralized control terminal is reduced conveniently in sudden overcast and rainy days, and the working efficiency of the centralized control terminal is quickened.
