[0002] Photovoltaic theory mainly involves the basic principles of solar photovoltaic power generation, system composition and key factors affecting power generation. Among them, the factors that directly affect power generation also include irradiance. The stronger the light, the more solar energy the photovoltaic module can capture, and the more electricity it generates. The group issues the planned power generation to the regional centralized control center, which will monitor the data of each site, evaluate the power according to the irradiation intensity, the grid connection of the unit, and the solar energy conversion efficiency, and obtain the theoretical power generation, so as to ensure the system efficiency and theoretical power deviation of the power. The regional centralized control center will report the generated power data before 3 am. If the data is reasonable and correct, it is necessary to warn the indicator page. The smaller the theoretical deviation, the higher the system power generation efficiency. Therefore, the theoretical power generation and daily deviation warning need to be calculated and warned after 10 pm. Only then will the operation and maintenance personnel find and correct the problem. Therefore, it is necessary to develop a method to calculate and warn in the report to ensure that the data is more efficient and accurate, and the problem can be highlighted quickly.

[0043] Embodiment 1

[0044] refer to Figure 1 The method for calculating the theoretical photovoltaic power generation based on the report form of the present invention comprises the following steps:

[0045] Precondition: The real-time library of the first zone of Maijie is normal and the program is normal.

[0046] 1) Check whether the configured station basic information table has data and ensure that the basic information is complete;

[0047] It should be noted that the basic information of the station is sent down by the group to the regional centralized control, and it is necessary to verify whether it exists, and the ID is an external ID established by the relationship library. The purpose is that the external ID is transparent and more unified with the group, which facilitates data transmission and data update.

[0048] 2) Establish the connection (bridge) between the Maijie real-time database of the first zone and the relationship database of the third zone. Since there is no station ID information in the Maijie database, it is necessary to establish a bridge through the calculation point code of the first zone to prepare for the subsequent data development. Specifically, the existing calculation point information is first synchronized to the new table structure. The table structure is provided with fields such as the station external ID and the calculation point code. For example, the power generation is POWER_DAY to store the power generation calculation point; for example, the Dawa station ID is 67, and the power generation code is DW_LN_XXXX_PWODER; the missing calculation points in the region are reported to the relationship database through the report to ensure one-to-one correspondence with the station to form a standard two-dimensional table structure. It should be noted that the calculation point code and the station external ID are unique, and the calculation point ensures that the data is normally taken in the Maijie database, where each measurement point is internally associated with a custom formula.

[0049] 3) Statistics of grid-connected capacity at the station, where the grid-connected capacity is based on the cumulative grid-connected capacity and sum (capacity) of the equipment status at the station, which is connected and grid-connected. It should be noted that the inverter is divided into connected, unconnected, debugging, grid-connected and other states. When the grid-connected date is after the statistical time, it is not included in the calculation.

[0050] 4) Photovoltaic power is currently divided into centralized, industrial and commercial distributed, and household distributed. Among them, household distributed has no irradiance information, so report development is used to fill in the Maijie real-time database, and the external ID code of the site is entered into the Maijie real-time database one by one.

[0051] 5) Set up a database connection in the report server, query the calculation point codes of the three zones, and then batch query the data of the first zone based on the codes.

[0052] 6) Calculate theoretical power generation.

[0053] Household photovoltaics do not have irradiance calculation point information that needs to be filled in. It is necessary to judge according to the type of site, take the irradiance value, and calculate its theoretical power generation. Among them, the site grid-connected capacity * irradiance * theoretical coefficient = theoretical power generation. The theoretical coefficient is obtained based on the calculation point of Zone 1. The theoretical coefficient is set by the site and the manufacturer.

[0054] 7) Power generation warning.

[0055] The power generation is calculated from the bottom of the collector line. The meter may have line jumps or other problems, resulting in abnormal data, which requires page warnings and normal corrections. Configure the corresponding site power measurement points to monitor whether the collector line jumps and obtain fixed-point data values. When the measurement point is 1, the page will issue a power warning and prompt for correction to prevent impact on other reported indicators.

[0056] 8) Determine the daily deviation value of theoretical power generation and issue an early warning.

[0057] When the absolute value of (theoretical power generation – actual power generation) / theoretical power generation * 100% is between 0-10%, the data is reasonable. When it is between 10-20%, a yellow warning is displayed and the radiation conditions of the day are checked. When it is greater than 20%, a red warning is displayed, prompting you to check the data before reporting, and check whether the equipment is in a state of fault maintenance, power restriction, offline, etc. on that day, and explain the reasons to avoid affecting the report.

[0058] It should be noted that the current theoretical photovoltaic power generation of the regional centralized control center is calculated according to the benchmark inverter, that is, the theoretical photovoltaic power generation = (sum (power generation of the benchmark inverter) / sum (number of benchmark inverters) * sum (total number of stations)). This method is acceptable, but not rigorous enough and has large errors. When a benchmark fails or goes offline, it will affect the total theoretical power generation, and the key cause cannot be found, and the theoretical deviation will obviously have a larger error. Therefore, it is necessary to define a more suitable theoretical power method through regional centralized control based on the power issued by the group and other factors such as the environment. This method calculates the solar energy conversion efficiency as the theoretical power generation coefficient according to the grid-connected capacity of the inverter and the inverter irradiation value of the station, and the centralized control according to the location of each station, and maintains it to the measuring point. It is time-saving and convenient to change the method later without modifying the calculation point. From this, we can get the theoretical power generation of the station = grid-connected capacity * irradiance * theoretical coefficient, and determine the deviation between the power generation and the theoretical power generation. If it exceeds the specified percentage, an early warning will be issued. At the same time, because the power generation is calculated from the bottom of the collector meter, the meter will have line jumps or other problems, resulting in abnormal data, and a page early warning is needed to prevent inaccurate deviations due to meter problems (theoretical deviation = (theoretical power generation-power generation) / theoretical power generation*100%). The operation and maintenance center personnel can check whether the inverter under the station is in a state of failure, maintenance, offline, and other possible problems, report the cause of the problem, and check the rationality of the data. The report page development calculates the theoretical power generation and can issue a normal early warning, which greatly reduces errors, is easy to maintain, and locks problems more quickly. It can also report correct data within the specified time, reducing more verification costs and saving time and effort.
