Description

  The present invention relates to a system for remotely monitoring a power generation state of a photovoltaic power generation system.

In recent years, there has been an increasing interest in reducing CO2 emissions that cause global warming, and alternative energy for fossil fuels that are expected to be depleted.

In such a photovoltaic power generation system, the system owner (user) constantly monitors the status of the system when there is a situation where power generation cannot be performed due to some system failure or the power generation amount is greatly reduced. If it is difficult to detect the abnormal state, or if the user is not aware of the abnormal state, the faulty state of the system is left as it is, and the amount of power generation is zero or reduced over a long period, which is disadvantageous for the user.
As a solution, for example, a system as shown in Patent Document 1 has been proposed. Patent Document 1 discloses a solar power generation system that monitors a solar power generation system from a remote location via the Internet, diagnoses a system failure from information such as the amount of power generation, and notifies the user when a failure is diagnosed.

In the solar power generation system as shown in the above prior art, when a user is notified that a failure has been diagnosed, it is necessary to make a repair request separately to the repair company, and thus a prompt response cannot be obtained. Took time to complete the repair, and there was a risk of loss of power generation that would have been obtained during that period.
In addition, repairs and other measures are not taken for reduced power generation due to other causes that are not diagnosed as malfunctions (for example, bad weather or changes in the installation environment). There was a problem that led to profits.

  The present invention has been made in order to solve the above-described problems, and is a power generation amount monitoring system for eliminating a user's disadvantage due to a loss during a failure period or a decrease in power generation amount due to a cause other than a failure.

Embodiment 1 FIG.
1 to 3 are block configuration diagrams of a photovoltaic power generation system and a power generation data output device, a block configuration diagram of a power generation data management device, and a block configuration of a power generation amount management system, respectively, in Embodiment 1 for carrying out the present invention. FIG. The first embodiment will be described with reference to these drawings.

First, the configuration and operation of the photovoltaic power generation system 1 and the power generation data output device 8 will be described with reference to FIG.
The photovoltaic power generation system 1 has a configuration in which a plurality of solar cell modules 2 connected in series with one another are connected in parallel, and each output is connected to a power conditioner 4 via a connection box 3. It has become.
As an operation, the output of the DC power generated by the plurality of solar cell modules 2 is collected in the connection box 3 and then input to the power conditioner 4, and the DC power input to the power conditioner 4 is changed. It converts to AC power and outputs it.
This AC power output is supplied to the load 7 in the house via the distribution board 5, and the surplus power generated without being consumed by the load 7 connected to the grid power supply 6 is connected to the grid power supply 6. (Power sale). When the generated power is low, such as when it is cloudy or rainy, or when the power cannot be generated at night, the insufficient power is supplied from the system power supply 6 via the distribution board 5 to the load 7 in the house ( Power purchase).

The power generation data output device 8 includes AC power measurement means 9 that measures the AC power output of the solar power generation system 1, power generation power data generation means 10, standard power generation amount setting means 11, and output means 12.
The AC power measuring unit 9 includes a current sensor that measures the AC output current of the photovoltaic power generation system 1 and a voltage sensor that measures the AC output voltage, and sends the measurement result to the generated power data generation unit 10. The generated power data generation means 10 calculates the AC output power from the current data and voltage data, which are the measurement results from the AC power measuring means 9, and uses this as the generated power data. The standard power generation amount setting means 11 inputs the capability (output rated value, each characteristic, etc.) of the solar power generation system 1, the latitude, longitude, terrain information, past weather data, etc. A standard amount of generated power in a reference period (for example, one year) of the solar power generation system 1 is estimated and set. These generated power data and standard generated power amount data can be transmitted to the outside by the output means 12.
Here, the case where the AC power measuring means 9 is composed of a current sensor and a voltage sensor is shown, but a method of directly obtaining data from the power conditioner 4 through communication may be used.

Next, the configuration and operation of the power generation data management device 13 will be described with reference to FIG.
The power generation data management device 13 includes an input unit 14, a power generation data storage unit 15, a power amount comparison unit 16, and an output unit 17.
The power generation data storage unit 15 stores the generated power data and the standard generated power amount data obtained through the input unit 14. It is assumed that the generated power data is all input data or data at any sampling period. The data of the standard power generation amount is updated or accumulated when the setting condition is changed. The power amount comparison unit 16 calculates the generated power amount for an arbitrary predetermined period (for example, 2 years, 10 years, etc.) by performing calculation such as integration of the generated power data stored in the power generation data storage unit 15 by the calculation unit. calculate. Further, based on the data of the standard power generation amount with respect to the reference period stored in the power generation data storage unit 15, the standard power generation amount corresponding to an arbitrary predetermined period (for example, 2 years, 10 years, etc.) is calculated. Then, the comparison unit compares the generated power amount for an arbitrary predetermined period and the standard generated power amount for an arbitrary predetermined period, and obtains as a comparison result which is a larger value and how much the difference is. . The comparison result data can be transmitted to the outside by the output means 17.

Next, the configuration and operation of the generated power amount management system 18 in the present embodiment will be described with reference to FIG.
The power generation data output device 8 and the power generation data management device 13 are connected to the Internet 19 so that the respective data can be communicated with each other. Furthermore, the service terminal device 20 is connected to the Internet 19 and can communicate with the power generation data output device 8 and the power generation data management device 13.
With this configuration, the generated power amount management system 18 operates as follows. First, the power generation data output device 8 transmits the power generation data of the solar power generation system 1 and the data of the standard power generation amount to the power generation data management device 13 via the Internet 19. The power generation data management device 13 is based on the generated power data and the standard generated power amount data obtained via the Internet 19, and the generated power amount for any given period and the standard for any given period of the solar power generation system 1. Calculate and compare the amount of power generated. Then, the comparison result is transmitted to the service terminal device 20 via the Internet 19. The service terminal device 20 receives the comparison result from the power generation data management device 13 via the Internet 19.
In this embodiment, mutual communication is realized by connecting to the Internet. However, the network is not limited to the Internet as long as data communication is possible.

Here, the comparison result acquired by the service terminal device 20 can cause the following actions.
That is, as a first action example, a service provider that has concluded a contract for maintenance, inspection, or repair of the photovoltaic power generation system 1 with a user (user) of the photovoltaic power generation system 1 is compared by the service terminal device 20. Check the result, and the amount of generated power in a certain period (for example, 2 years) is smaller than the standard generated power corresponding to that period (or the amount of generated power in a certain period is less than the standard generated power corresponding to that period) And the difference exceeds a predetermined value), the photovoltaic power generation system 1 determines that the amount of power generation has decreased for some reason, and visits the site to perform maintenance or inspection of the system. Implement and investigate the cause of power generation decline. As a result, if a failure is confirmed, it is repaired, and if a cause other than the failure is found, it is removed and measures are taken to recover the power generation amount. Note that the cause other than the failure is that the surface of the solar cell module is covered with something that blocks light, such as falling leaves, the surface of the solar cell module is soiled with dust, or the power conditioner. Various things other than simple equipment and component failures are conceivable, such as when the vicinity is hot for some reason and the function of limiting the output is working.

As a second action example, an insurer who has signed a power generation amount guarantee contract with a user of the photovoltaic power generation system 1 confirms the comparison result with the service terminal device 20 and pays the insurance money. is there.
The amount of power generated by a solar power generation system varies depending on the environmental conditions of the installation site, the amount of solar radiation, and weather conditions such as temperature. In addition, the power generation amount may be reduced due to aging of the system or in some cases failure. However, since the initial investment amount is large, it is an important problem for those considering the installation whether or not the solar power generation system can be installed and paid.
Therefore, if the amount of power generation in a predetermined period is lower than the scheduled value, the user can install and operate the solar power generation system with peace of mind if an insurance contract for paying compensation is concluded with the insurer. Specific contents of such insurance are exemplified below.
(1) Calculate the expected power generation amount during the warranty period (eg 10 years) based on the rated capacity of the target photovoltaic power generation system, environmental information of the installation location, past weather information of the area, etc., and the guarantee rate ( For example, 90%) is multiplied to determine the guaranteed power generation amount.
(2) The guaranteed amount of electricity multiplied by the guaranteed unit price (for example, the surplus purchase unit price) is the guaranteed amount (in the case of a full amount). The amount of insurance multiplied by the insurance premium rate is the insurance amount. The user of the solar power generation system pays this insurance amount to the insurer to conclude a contract.
(3) At the end of the warranty period, if the actual power generation amount of the solar power generation system is less than the guaranteed power generation amount, the insurer shall use the amount of unsatisfied power generation x the guaranteed unit price as compensation money. Pay to the user.
The actual power generation amount at the end of the warranty period in the insurance program as described above (power generation amount for a predetermined period in the present embodiment), guaranteed power generation amount (standard power generation for the predetermined period in the present embodiment) Amount) comparison result (comparison result in the present embodiment) is automatically transmitted to the service terminal device 20 in the generated power amount management system 18 of the present embodiment. There is no need to separately calculate the amount of guaranteed power generation, accumulation of actual power generation, comparison after the expiration of the insurance period, etc., which is extremely effective in terms of procedures and operations.

  In the first embodiment, the generated power data output from the power generation data output device 8 has been described as the AC output power of the photovoltaic power generation system. However, the calculation is performed up to the unit amount of power obtained by accumulating the AC output power. May be. Or the total electric power generation amount after the solar power generation system 1 is installed may be sufficient. In this case, when the power generation data management device 13 calculates the power generation amount for an arbitrary predetermined period, the power amount of the unit period within an arbitrary predetermined period is integrated, or the total power generation amount at the end of the arbitrary predetermined period This can be done by taking the difference between the total amount of power generated at the start of the project.

  Since the first embodiment is configured as described above, in the power generation amount management system in which the power generation data output device, the power generation data management device, and the service terminal device are connected to each other via the Internet, the measurement of the generated power of the solar power generation system is performed. , Calculation of power generation amount, setting of standard power generation amount, comparison of power generation amount and standard power generation amount in a predetermined period, and the comparison result can be acquired by the service terminal device, so that the maintenance of the solar power generation system, The action of guaranteeing the amount of power generation can be performed efficiently, and the disadvantage of the user due to loss during the failure period of the solar power generation system or a decrease in the amount of power generation due to a cause other than the failure can be solved.

That is, in the second embodiment, the first action and the second action can be performed separately by another operator independently or in parallel.
In this configuration, for example, the insurer is in the middle of the power generation status of the solar power generation system 1 based on information from the second service terminal device 22 (for example, a comparison result between the actual power generation amount and the standard power generation amount in the second year). If the actual power generation amount at that time is below or close to the guaranteed power generation amount, the solar power generation system may have some cause for the decrease in power generation amount. It is possible to issue a maintenance command to the service terminal device 21 and have the service provider check early. In other words, if there is some abnormality or cause and it is left as it is, it will happen that the amount of generated power will be significantly lower and it will be necessary to pay compensation to the user when the warranty period has finally passed. Can be prevented. Of course, it is effective not only to prevent losses of insurance companies, but also to prevent losses from expected power generation even when considered as global energy.

The power generation data output devices 8a and 8b store preset identification information unique to the solar power generation systems 1a and 1b to which the power generation data output devices 8a and 8b are connected, respectively. That is, with this identification information, the generated power amount management system 18 can identify the photovoltaic power generation system 1a and the photovoltaic power generation system 1b.
Specifically, the power generation data output device 8a adds identification information unique to the solar power generation system 1a and outputs it on the Internet 19 when outputting the power generation data of the solar power generation system 1a and the data of the standard power generation amount. Send it out. The power generation data management device 13 determines the power generation amount and arbitrary power of the solar power generation system 1 a based on the power generation data of the solar power generation system 1 a and the data of the standard power generation amount obtained via the Internet 19. The amount of standard generated power for a predetermined period is calculated and compared. Then, identification information unique to the photovoltaic power generation system 1 a is added to the comparison result for the photovoltaic power generation system 1 a and transmitted to the first service terminal device 21 and the second service terminal device 22 via the Internet 19. Therefore, the first service terminal device 21 and the second service terminal device 22 receive the comparison results of each of the plurality of photovoltaic power generation systems, and recognize which photovoltaic power generation system these are the comparison results from the identification information. can do.
In the description of the present embodiment, the case where two sets of the solar power generation system 1a and the power generation data output device 8a, the solar power generation system 1b, and the power generation data output device 8b are connected is shown. Even when the photovoltaic power generation system and the power generation data output device are connected, the same effect can be obtained.

As a result, if the service provider has a photovoltaic power generation system in which the amount of power generation is reduced among the plurality of photovoltaic power generation systems based on the information received by the first service terminal device 21, the photovoltaic power generation system Therefore, maintenance or inspection can be performed promptly.
Further, the insurer confirms the progress of the power generation status of the plurality of photovoltaic power generation systems based on the information received by the second service terminal device 22, and the actual power generation amount at that time is below the guaranteed power generation amount. If there is a solar power generation system that is or is close to the system, a maintenance command for the solar power generation system can be issued to the first service terminal device 21 so that the service provider can check it early. It is more effective if the maintenance command is configured to be automatically issued from the first service terminal device 21 to the second service terminal device 22. In addition, if there is a solar power generation system whose actual power generation amount did not meet the guaranteed power generation amount at the end of the warranty period, the insurer uses the corresponding solar power generation system promptly without requiring an extra tabulation period.
