Detailed Description

Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. However, the scope of the right of the present invention is not limited or restricted by these examples. In the drawings, the same constituent elements are denoted by the same reference numerals.

Terms used in the following description are selected as general terms widely used in the related art, but may be expressed as other terms according to the development and/or alteration of technology, convention, preference of those skilled in the art, and the like. Therefore, the terms used in the following description should not be construed as limiting the technical idea of the present invention, but should be construed as exemplary terms for describing the embodiments.

In addition, in certain cases, certain terms are arbitrarily selected by the applicant, and at this time, their detailed meanings will be described in the corresponding descriptions. Therefore, terms used in the following description should be understood according to the meanings of the terms and the entire contents in the present specification, not just the names of the terms.

FIG. 1 is a drawing showing a solar module installed in a similar premises according to one embodiment.

An integrated monitoring system according to an embodiment may monitor power generation systems installed in a plurality of areas. The power generation system is a power generation system using new renewable energy, and may be, for example, a solar power generation system, but is not limited thereto. Fig. 1 shows a house 110, 120, 130 in which a solar power generation system is installed.

Due to the nature of solar energy, the amount of electricity generated varies with climate, terrain, azimuth and shadow disturbances in the installation area, and therefore maintenance management after initial installation is particularly important. Existing solar power generation systems are maintained and managed by notification and visual inspection in the facility system.

For example, it relies on notification of a failure of an inverter connected to a solar module and notification of various sensors connected to a solar power generation system. However, factors that affect the power generation amount are many in practice. Specifically, if foreign matter (a mop, leaves, etc.) exists on the solar module, no notification may be given, but the power generation amount may be affected.

Fig. 2 is a diagram showing a configuration of an integrated monitoring system for managing a power generation system of a plurality of areas according to an embodiment.

The integrated monitoring system 200 may monitor power generation systems of multiple regions. For example, the power generation system of the a-zone 210, the power generation system of the B-zone 220, and the power generation system of the C-zone 230 may be monitored simultaneously.

The a, B and C areas 210, 220 and 230 may be areas having different geographical features, but may be areas having similar geographical features in some cases. Three regions are described as an example, but the number of regions is not limited thereto, and a plurality of or two regions may also be monitored.

Specifically, the a-zone 210 and the B-zone 220 may be adjacent zones and have similar meteorological and geographic environments; the C-region 230 may be a region far from the a-region 210 and the B-region 220 and have different environmental factors.

FIG. 3 is a diagram illustrating a zone specific power generation system according to one embodiment.

For example, the power generation device of the power generation system 310 using the new renewable energy may include solar power generation, solar thermal power generation, wind power generation, and the like, but is not limited thereto. In some cases, other types of new renewable energy sources may also be used.

Specifically, the power generation device includes at least one or more of a solar power generation device, a solar thermal power generation device, and a geothermal power generation device. For example, when the power generation device is a solar power generation device, a solar panel may be included and energy may be taken from sunlight, thereby generating electricity.

The analysis unit analyzes the power generation data generated by the power generation device. For example, when a solar power generation device is used, information on the amount of power generation, the time of power generation, and the like generated can be analyzed. Further, information on the weekly power generation amount and the like can also be analyzed by calculating the total amount of power generation per day.

The communication part may transmit the data generated from the analysis part to an integrated monitoring system. That is, the communication section may transmit data on the amount of power generation and the like analyzed by the analysis section to the integrated monitoring system so that the integrated monitoring system may integrally manage the plurality of power generation systems.

Fig. 4 is a flowchart illustrating determining whether a specific power generation system is abnormal according to an embodiment. The method of determining abnormality or non-abnormality of the power generation system may include the steps of: collecting power generation amount data 410, selecting a similar region 420, converting a power generation time index 430, comparing a power generation time index 440, and determining whether there is an abnormality 450.

Specifically, the step 410 of collecting power generation amount data is a step of collecting power generation amount data from a plurality of power generation systems. The plurality of power generation systems means that the power generation system of fig. 3 exists in a plurality of forms. Therefore, the plurality of power generation systems may be power generation systems using new renewable energy, and may be, for example, power generation systems using energy such as solar energy, solar heat, wind energy, geothermal energy, or the like, but are not limited thereto.

Collecting power generation amount data from the plurality of power generation systems. As the power generation amount data, all information on the power generation time point, the power generation time, and the like may be collected in addition to the power generation amount. In addition, various information associated with the amount of power generation, such as the geographical location of the power generation system, the geographical environment, the climate environment, and the like, may be further collected. According to another embodiment, the information related to the power generation system as the power generation system installation information may include an installation date, a module angle, a module azimuth angle, a module type, an inverter type, and the like of the power generation system.

The step 420 of selecting a similar region is a step of selecting a similar region based on the power generation amount data collected from the plurality of power generation systems. The similar region does not simply mean a spatially adjacent region, but may also mean a region having a similar power generation amount or power generation time of the power generation system.

Specifically, in the case of selection based on the geographical location of the power generation system, a range within a predetermined radius from a specific location may be determined as a similar area. Alternatively, a region having a similar geographical environment to the particular power generation system may also be selected as the similar region. For example, a region having mountains and mountains located in the south from the position where the power generation system is installed may be selected as the similar region, or a region where the power generation system is installed on the roof of a building having five or more floors may be selected as the similar region.

In addition to the method of selecting similar areas based on geographic environment, similar areas may also be selected based on climate environment. For example, an area having 10 hours or more of sunshine per day may be selected as the similar area. Alternatively, a power generation system having a daily power generation amount of 10kWh or more may be selected as the similar region.

The similar region selection method is provided as an example only, and the similar region may be selected by various applications.

The step of converting the electricity generation time index 430 is a step of converting the amount of electricity generated by the electricity generation system into an electricity generation time index. Specifically, the power generation time index may be calculated by dividing the amount of power generation for a predetermined period of time of the power generation system by the power generation capacity. For example, when calculating the power generation time index for one day, if the power generation amount is 400kWh and the power generation capacity is 500kW for 24 hours, the power generation time index may be 0.8. In some cases, the calculation may be performed based on the power generation amount for one week or one month.

The step 440 of comparing the index of the power generation time is a step of comparing the power generation time between the power generation systems selected as the similar region. The electricity generation time index is associated with the amount of electricity generation as an index calculated in the step of converting the electricity generation time index 430.

In the step 440 of comparing the electricity generation time indices, the electricity generation time indices between the electricity generation systems of the similar regions may be compared. The abnormality or not may be determined by comparing the power generation time indexes of the first power generation system and the second power generation system, which is step 450. Not only two power generation systems but also more power generation systems may be compared, and it may be determined which system has a larger or smaller power generation time index.

In the step 440 of comparing the electricity generation time indexes, the electricity generation time indexes corresponding to the daily electricity generation amount may be compared, and in some cases, the electricity generation time index of each region, the electricity generation time index of each season, the electricity generation time index of each year, the electricity generation time index of each week, the electricity generation time index of each month, the electricity generation time index of a user-designated period, and the like may also be compared. Alternatively, the average power generation time index of the power generation systems of the similar region may be calculated, or the average power generation time index and the power generation time index of the specific power generation system may be compared.

Finally, in the determine abnormality or not step 450, it is determined whether there is an abnormality using the power generation time index. Specifically, if the same solar power generation system and different power generation time indexes are obtained from power generation systems of similar regions having the same power generation time, it may be determined that there is an abnormality.

For example, but not limited to, solar power generation is most affected by ambient solar radiation. Based on the systems having the same power generation capacity, it can be determined that an abnormality has occurred in the solar module (or panel) when the surrounding power generation systems generate a certain amount of power but the amount of power generated by a particular power generation system drastically decreases. For example, the abnormality may be a problem such as a foreign object blocking sunlight from entering the solar module, or a problem such as the light tracking function of the module not being properly performed.

However, this is only an example and may be caused by other problems. When the amount of power generation is reduced by an amount greater than a predetermined value, the system may be configured to determine that there is an abnormality and send a notification to the user.

When receiving the abnormality notification, the user may check the power generation system. If there is an abnormality, appropriate measures can be taken.

According to another embodiment, in determining whether or not there is an abnormality, the abnormality or not may be determined by comparing product models of a specific power generation system. By making a comparison between the same product models, it is possible to determine whether or not there is an abnormality more accurately, in addition to making a comparison between power generation systems of similar regions. Alternatively, methods that only compare between the same product models may be employed, without the need to compare systems in similar regions.

According to another embodiment, a system for re-determining the presence or absence of an anomaly using a machine learning model is also possible. The machine learning portion may perform machine learning based on the power generation amount data and the abnormality or non-abnormality, and newly determine whether the power generation system is abnormal or not.

Machine Learning (Machine Learning) is a field of artificial intelligence in computer science, which has been developed on the basis of pattern recognition and computer Learning theories. Machine learning is a technique for studying and constructing systems that learn, predict, and improve their performance and algorithms based on empirical data. Machine learning algorithms employ building a specific model to derive predictions or decisions based on input data rather than executing well-defined static program instructions.

For example, through machine learning, the machine learning portion may obtain output data for determining whether the power generation system is abnormal or predicting power generation amount data based on factors affecting the power generation amount in solar power generation as input data. That is, the output data associated with the input data may be output based on environmental factors, facility factors, or the like that affect the amount of power generation as input data.

Specifically, the machine learning portion may perform machine learning using the power generation time index data or the power generation amount data and the abnormality or non-abnormality result determined by the processor. The machine learning portion may perform learning by matching the abnormality or non-abnormality result corresponding to the power generation time index or the power generation amount.

The trained machine learning part may re-determine whether there is an abnormality using the power generation time index corresponding to the result of the abnormality or not of the specific power generation system determined by the processor. By using the machine learning section, determination errors of the processor can be reduced.

FIG. 5 is a diagram illustrating monitoring of a condition of a particular area using an integrated monitoring system according to one embodiment. In the integrated monitoring system, the installation condition of the power generation system in a specific area can be confirmed.

Fig. 5 shows a state where a plurality of transmitters and repeaters and one concentrator are installed.

For example, fig. 5 shows a state of a power generation system installed in a specific area. T denotes a transmitter, R denotes a repeater, and C denotes a concentrator.

The Transmitter (Transmitter) may correspond to the communication section of fig. 3. The transmitter may transmit the collected energy data for each home to the repeater. A Repeater (Repeater) can transmit data received from a plurality of transmitters to a greater distance. That is, the transmission distance can be extended. A Concentrator (Concentrator) may be used to collect the transmitter data.

According to another embodiment, communication can also be performed in a Low Power Wide Area (LPWA) or the like at Low Power in a Wide Area without a repeater. That is, similar to the concept of the Internet of Things (IOT), the transmitter can directly perform long-distance communication through the concentrator without passing through the repeater.

The transmitter refers to a location of a power generation system installed in each house. For example, the energy source generated by solar energy in each house may transmit corresponding information to the transmitter through the inverter. For example, it may be a Remote Terminal Unit (RTU) device, but is not limited thereto. The information can be transmitted using an RF modem (modem) to a trunk line for forwarding and then to a concentrator that receives the final data in order to collect all the data.

Furthermore, according to another embodiment, data may also be collected according to 3G or Long Term Evolution (LTE) communication methods using Internet of Things (IOT) private networks.

The houses shown on the map of fig. 5 may be located in villages that receive the same weather information. Some errors may occur due to structural position of the solar module or shadow disturbances, but most of the generation time should be approximately measured as similar or the same to be certain to operate properly and without failure. Therefore, if the power generation time of one house out of the ten houses is too low or too high, it can be determined that the inspection is required. That is, it can be determined that there is an abnormality.

FIG. 6 is a diagram illustrating a management configuration of an integrated monitoring system according to one embodiment. The integrated monitoring system 600 according to an embodiment may include an integrated monitoring related function 610, a fault information related function 620, and an integrated dashboard related function 630.

First, the monitoring related function 610 of the integrated monitoring system 600 may monitor the real-time power generation amount. For example, the current power produced by a particular power generation system may be identified.

Further, data accumulated over time may be used to monitor power generation statistical trends. Specifically, a daily power generation amount trend, a weekly power generation amount trend, a monthly or yearly power generation amount trend, or the like can be confirmed. In some cases, it is also possible to confirm the power generation amount trend according to each season or the quarterly power generation amount trend.

The integrated monitoring system can analyze and monitor each customer. That is, the amount of power generation can be confirmed for each power generation system. The real-time power generation amount and the power generation statistical trend can be monitored for each specific area, and each power generation system can also be monitored.

Next, the fault information correlation function 620 of the integrated monitoring system 600 may confirm information on the inverter alarm and the alarm, data error and communication state of various sensors. In terms of inverter alarms, an inverter present in a power generation system may issue an alarm when the system is not operating properly. When the inverter alarm occurs, a user or an operator of the corresponding power generation system may confirm that there is an abnormality in the power generation system.

For example, if an overcurrent flows in the solar system, the inverter may detect the overcurrent and send an alarm message "overcurrent error".

For example, the alarm of the various sensors refers to an alarm generated by various sensors installed in the power generation system, such as an alarm generated by a CCTV tracking system of a power plant, an alarm generated by a power room of a solar power plant, an alarm generated by a sensor installed in a junction box of a solar power plant, and the like, but is not limited thereto.

The data error corresponds to a case where the collected power generation amount data has an error. For example, when the amount of power generation sharply increases or decreases on a specific date, it may be determined that the data has an error.

Further, with respect to the communication state-related content, it is possible to confirm a failure (error) such as a case where data cannot be appropriately collected due to an abnormality of the communication device.

Finally, the integrated dashboard related function 630 of the integrated monitoring system 600 may display various power generation amounts, average power generation time, TOE conversion coefficient, and the like. The total power generation amount per day/month/year can be displayed for a plurality of power generation systems monitored by the integrated monitoring system 600. In addition, an average power generation time of the plurality of power generation systems may be displayed. An average of all the monitored power generation systems may be calculated and displayed, and in some cases, an average of some systems may be calculated and displayed, such as power generation systems limited to similar areas. In addition, the TOE conversion coefficient may also be displayed. The Ton of Oil Equivalent (TOE) conversion coefficient is converted into the calorific value of petroleum according to the calorific value of energy. As a virtual unit for comparing various energy units, 1TOE corresponds to 1000 ten-thousand kcal. Therefore, the amount of power generation by the power generation system can be converted into the TOE conversion coefficient and displayed on the dashboard.

Fig. 7 is a diagram showing a real-time monitoring result of the integrated monitoring system according to an embodiment.

On the real-time screen of the integrated monitoring system according to an embodiment, information about the installation location, energy, capacity, today's power generation time index, today's cumulative power generation amount, alarm state, alarm content, address, and the like of the power generation system can be displayed. However, the above display contents are merely examples and are not limited thereto.

The installation location of the power generation system may include a residential house, a residential hall, a museum, a building, an apartment house, etc., and the energy source may be solar energy, solar thermal energy, geothermal energy, etc. In addition, the capacity may be a power generation capacity of the corresponding power generation system, an installation address of the power generation system may be displayed, and an icon that allows a house location to be displayed in a separate window may be displayed.

The present power generation time index may be a power generation time index represented by dividing the present cumulative power generation amount by the power generation capacity of the power generation system; the accumulated power generation amount of the day refers to the total power generation amount of the real-time monitoring time point of the day. The monitoring system can display the alarm state of each power generation system and can also display the content of corresponding alarm.

The real-time integrated monitoring system can be ranked based on various criteria and can also be changed to be ranked from low to high and from high to low. Further, a function of retrieving only power generation systems satisfying a specific reference may be performed. For example, only the power generation systems existing around the position of the predetermined area may be retrieved and monitored. According to another embodiment, it is also possible to retrieve only houses based on the type classification of the installation location.
