1 is a block diagram showing a schematic configuration of a machine learning-based solar power generation operation management system according to an embodiment of the present invention. A machine learning-based photovoltaic operation management system (hereinafter referred to as a system) according to an embodiment of the present invention includes a solar cell 100, a sunlight sensor 110, a connection panel 200, a management server 300, and a DB It may include (400).

The system of the present invention provides visually by monitoring the amount of sunlight, current amount, humidity and temperature of the connection panel 200 of the solar cell 100 as parameters during solar power generation operation, and a manager terminal when a risk factor is predicted during monitoring. You can notify (not shown).

At this time, the system of the present invention predicts a change trend by comparing the parameter collected in real time with a reference pattern analyzed based on big data machine learning, and periodically updates the reference pattern based on this, thereby accurately predicting the change trend.

The solar cell 100 converts light energy incident from the sun into electrical energy and outputs it. The solar cell 100 includes a plurality of solar cell arrays 100a to 100n. In addition, the solar cell array includes a plurality of solar cell modules. A number of solar cell modules, which are components of each solar cell array, are configured by being connected in series with each other.

The amount of sunlight sensor 110 is installed on the panel of the solar cell 100 to sense the amount of sunlight at the location where the solar cell 100 is installed in real time, and the sensed amount of sunlight is controlled through the communication unit 240 of the connection panel 200. It can be transmitted to 230.

The connection panel 200 compares the amount of sunlight received in real time from the sunlight amount sensor 110, the output current received from the solar cell 100, and the humidity and temperature in the connection panel 200 with a corresponding reference pattern to determine the change trend for each parameter. It is predictable.

Referring to FIG. 1, the connection panel 200 includes a switch 210, a sensor unit 220, a control unit 230 (MCU), a communication unit 240, a control circuit unit 250, a heat pump 260, and a fire extinguishing unit ( 270, and the sensor unit 220 may include a current sensor 221, a humidity sensor 222, and a thermal image sensor 223. In addition, the connection board 200 may be packaged using a functional fiber such as Gore-Tex, and a bolt to which Gore-Tex is applied may be used even when the enclosure is combined. Accordingly, when a differential pressure occurs due to a temperature change, pressure is balanced inside and outside the connection panel 200 by packaging and coupling bolts of the connection panel 200 using Gore-Tex to prevent external fluids (e.g., rain, etc.). It can prevent penetration and prevent condensation from occurring.

The switch 210 may receive the output power of the solar cell 100 in units of strings. In this case, the control circuit unit 250 may merge output power in units of strings received under the control of the controller 230 and provide them to the inverter.

The current sensor 222 may sense the current in each string unit from the output power received in the string unit of the solar cell 100 and provide it to the controller 230.

The humidity sensor 222 may sense the humidity in the connection panel 300 in real time and provide it to the control unit 230.

The thermal image sensor 223 may provide the controller 230 with a thermal image obtained by capturing a thermal image in the connection panel 300 in real time. In this case, the thermal image may be obtained by dividing the area within the connection panel 300 into a plurality of areas and photographing each area. In this case, the control circuit unit 250 having a high heat generation temperature may be intensively sensed.

Specifically, the thermal image sensor 220 may divide the area of the control circuit unit 250 by circuit configuration or by a unit area to obtain a real-time thermal image for each area location of the control circuit unit 250. In this case, the thermal image generated in real time may be transmitted to the controller 230.

Referring to FIG. 2, the controller 230 may include a memory 231 and a processor 232.

That is, the memory 231 may store the amount of sunlight, the amount of current for each string, the amount of humidity, and the thermal image for each region, and may store a reference pattern for each parameter that is updated from the management server 300 at a preset period.

Here, the reference pattern for each parameter is a pattern in which the amount of change of each parameter is analyzed based on big data machine learning in the management server 300, and environmental conditions such as the installation location (location, shade, etc.) of the solar cell, weather, season, time, etc. It can be analyzed in consideration of factors.

At this time, the installation location of the solar cell may be divided into a region and a plurality of locations installed within the region, and the system of the present invention may analyze and manage parameters for each location and region for monitoring. Meanwhile, the analysis of the reference pattern for each parameter will be described in detail when the management server 300 is described.

The processor 232 may compare the sensing value for each parameter stored in the memory 231 in real time with a reference pattern of a corresponding parameter to predict a change trend of the real-time parameter sensing value. With reference to FIG. 3, the prediction of the parameter change trend of the processor 232 will be described.

3 is a graph for explaining prediction of a parameter change trend according to an embodiment of the present invention. Referring to FIG. 3, the processor 232 may compare a pattern of parameters collected in real time (actual measurement) with a reference pattern previously stored in the memory 231. In this case, the pattern of the measured parameter and the reference pattern may represent a degree of change in the sensing value of the parameter sensing value over time.

At this time, the processor 232 samples the sensing values of the parameters collected in real time in units of a preset time interval, sets an interest interval (sampled unit interval) for predicting the trend of sensing values, and sets the sensing values of the parameters in the interest interval and The trend of sensing values may be predicted based on the current point t1 by comparing pattern values in the corresponding interest section of the reference pattern.

In this case, the sensing value trend prediction may use a short-term load forecasting (STLF) analysis technique. The processor 232 may extract the predicted inflection point P from the predicted sensing value trend pattern through the STLF analysis method.

When extracting the predicted inflection point (P), the processor 232 generates metadata including the amount of change in the sensing value and the predicted inflection point (P) in the interest section used for predicting the predicted inflection point (P) as change data, and the management server 300 ). That is, the related information may be transmitted to the management server 300 only when a change trend of a parameter according to the reference pattern is predicted.

In this case, the parameter may be an amount of sunlight, an amount of current, an amount of humidity, and the like, and may be a vector including time information.

Meanwhile, the processor 232 may transmit a thermal image for each area collected in real time from the thermal image sensor 222 to the management server 300 through the communication unit 240. At this time, the processor 232 compares the thermal image for each region generated in real time with a temperature reference pattern for each region in which a pre-stored environmental factor is considered, and if the temperature increases compared to the reference pattern, the temperature for the region increases. Can be notified to the management server 300.

In addition, the processor 232 immediately drives the fire extinguishing unit 270 to extinguish the fire when a spark occurs in a specific area or the temperature in a specific area rapidly rises above a preset temperature and a fire is expected, and the management server 300 Fire occurrence can be notified by.

The communication unit 240 may receive a sensing value received from the sunlight amount sensor 110 and the sensor unit 120 in real time, and may perform data transmission/reception between the control unit 230 and the management server 300.

The control circuit unit 250 may control driving of the switch 210, the heat pump 260, and the fire extinguishing unit 270 according to the control of the controller 230. In this case, the control unit 230 may control the driving of each component with the control circuit unit 250 according to the control signal received from the management server 300.

As an example, the control signal may be a signal for controlling off of a switch in which an abnormal current is detected, driving of a heat pump for humidity control, and the like.

The heat pump 260 may prevent the occurrence of condensation in the connection panel 200. A heat pump 260 of an air heat source type is provided in the connection panel 200 to control cooling and heating inside the connection panel, thereby controlling humidity. In this case, the reference for cooling and heating control may be a reference humidity for preventing condensation.

The control circuit unit 250 may control driving of the heat pump 260 by receiving a heat pump driving control signal for controlling the humidity inside the connection panel 200 to become the reference humidity from the analysis server 300. That is, the heat pump 260 is driven according to the control signal of the control circuit unit 250 to adjust the humidity inside the connection panel 200.

Accordingly, the connection panel 200 according to an embodiment of the present invention prevents condensation from occurring by a control signal that controls the packaging of the connection panel 200 using Gore-Tex and the bolt coupling structure and driving of the heat pump 260. Can be prevented.

That is, change data for each amount of sunlight, amount of current, and amount of humidity collected in real time, and thermal image images for each region may be stored based on time. In this case, each of the pieces of information may be classified for each connection panel 200.

In addition, the data collection unit 310 may collect information such as weather, temperature, humidity, rainfall, and amount of sunlight for each location of the solar cell 100 connected to the connection panel 200 from the meteorological office and store it in the DB 400.

The reference pattern generation unit 320 may generate a model for each parameter, that is, a reference pattern, using data collected by the data collection unit 310 and stored in the DB 400.

The reference pattern generation unit 320 generates a reference pattern for each connection panel 200, but considers environmental factors (solar cell installation location, shade, season, weather, etc.), and parameters for a preset period (for example, a day). You can create patterns. Accordingly, the reference pattern for each parameter of the amount of sunlight, current, and humidity is not a pattern having a fixed threshold, but may be generated in different models even at the same time according to environmental factors.

In addition, the reference pattern generation unit 320 analyzes the thermal image for each region based on machine learning, but generates a temperature reference pattern for each region in which environmental factors of the connection panel are considered and transmits it to the connection panel.

The reference pattern generation unit 320 may transmit and update the generated basic pattern to the connection panel 200 at a preset period.

Referring to FIG. 6, the measured sunlight amount pattern may be a pattern generated by analyzing sunlight amount change data based on machine learning. In addition, the measured current amount pattern may be a pattern generated by analyzing current amount change data based on machine learning.

The abnormality predictor 340 may determine a degree of similarity between the correlation between the measured sunlight amount pattern and the measured current amount pattern with the correlation between the sunlight amount reference pattern and the current amount reference pattern of FIG. 5. Referring to FIG. 6, when comparing the correlation between the reference pattern of the amount of sunlight and the reference pattern of the amount of current, the occurrence of an abnormality is predicted at a location where the correlation between the measured amount of sunlight pattern and the measured amount of current pattern is different, that is, a portion with low correlation similarity (abnormality prediction). Can be.

When determining a current abnormality, the abnormality predicting unit 340 notifies the manager terminal (not shown), and transmits a control signal for turning off the switch of the corresponding solar cell module determined as the current abnormality to the connection panel 200, and By controlling 210, reverse current can be prevented.
