The RTU equipment 300 may have a communication modem (not shown) for communication with the server provided therein.

The communication antenna 310 is an antenna of the communication modem, and may be installed in the RTU equipment 300 in an upright state.

The modem status LED 320 is a status LED of the communication modem, and may be lit in red when power is turned on, and lit in green when connected to a base station.

The data transmission switch 330 may be a button for transmitting data such as the amount of power measured by the RTU equipment 300 or detection information to the server.

The RTU equipment 300 may transmit data to the solar power plant monitoring service providing system 200 when the data transmission switch 330 is pushed in while the communication modem is connected to the base station.

In addition, a fixing hole for fixing the RTU equipment 300 to a wall or other installation part may be provided outside the RTU equipment 300 .

The RTU equipment 300 may be designed to be compatible with various inverter equipment of various manufacturers, and does not require a separate Internet line using wireless communication, thereby reducing costs.

Since the RTU equipment 300 has a small size of approximately 120 x 90 x 35 mm, it is easy to install and can maintain high communication sensitivity even inside a building or enclosure.

If there is a space to install the RTU equipment 300 inside the inverter equipment, the communication port 380 of the RTU equipment 300 may be connected to the RS485 terminal inside the inverter, and the power of the adapter may be connected. Alternatively, when installing the RTU equipment 300 on the outside of the inverter equipment, a sealed plastic box may be used.

The RTU equipment 300 may start communication with the inverter equipment after generating a certain sound effect when power is applied. Communication between the RTU equipment 300 and the inverter equipment may be made at a predetermined time interval, for example, once per second, and there is a difference in the number of data and the number of transmissions depending on the inverter equipment.

In addition, the RTU equipment 300 may start communication with the server when a predetermined time (30 seconds) passes after power is applied. Communication between the RTU equipment 300 and the server may be made at a predetermined time interval, for example, at an interval of 10 minutes.

If the time during which data is not received from the inverter equipment is 3 seconds or more, the RTU equipment 300 recognizes the power failure of the inverter equipment, and in this case, the data can be immediately transmitted to the server.

After the RTU device 300 generates an effect sound (“beep”) when it starts sending data to the server, it sequentially transmits inverter information (output of individual inverter devices) along with RTU information (eg, serial number), and finally After transmitting the output of the inverter equipment, another sound effect (“beep beep”) can be generated to indicate the end of data transmission.

According to an embodiment, the solar power plant monitoring service providing system 200 may be configured to include a weather check unit 230 and a power generation control unit 240 .

The weather check unit 230 functions to check the weather information of the location where the solar power plant is installed from the weather providing server in real time, based on the location information of the solar power plant.

For example, the weather check unit 230 uses the serial number of the RTU equipment used to collect the amount of power generation, and searches for the location information of the solar power plant in which the RTU equipment is installed in the RTU table, and the location information corresponds to Weather information at the point can be checked from the weather providing server.

The RTU table, the location information of the photovoltaic power plant in which the RTU equipment is installed, may be recorded in association with the serial number of the RTU equipment.

The power generation control unit 240 functions to control power generation in the solar power plant according to the weather information.

For example, the power generation control unit 240 adjusts the target generation amount preset in the solar power plant according to the weather information checked from the weather providing server, and according to the adjusted target generation amount, the output from the individual inverter equipment installed in the solar power plant By controlling the power generation control for the solar power plant can be performed.

For example, when the target generation amount of the solar power plant is preset to '100', the power generation control unit 240 maintains the target generation amount as it is if the weather information checked in real time is 'sunny, temperature 25 degrees', and the weather information is ' If it is sunny and the temperature is 27 degrees or higher, the target generation is adjusted to decrease by 10%, if the weather information is 'cloudy, the temperature is 20 degrees', the target generation is adjusted to increase by 10%, and if the weather information is 'snow or rain, the temperature is 18 degrees' ' or less', the target power generation can be adjusted to increase by 20%.

The power generation control unit 240 may control the output of the individual inverter devices so that the sum of the outputs from the individual inverter devices installed in the solar power plant is equal to or greater than the adjusted target power generation amount.

The power generation information may include an actual power generation amount collected and measured through the RTU equipment, and a power generation amount corresponding thereto, and the actual power generation amount may be calculated differently depending on a reference time point.

For example, when the reference time is selected as '0' today, the power generation information may include the current generation amount calculated up to the time monitoring is requested and the corresponding generation amount.

In addition, when the reference point is selected as '0' on every Monday, the amount of power generated this week and the amount of power corresponding thereto calculated until the time when monitoring is requested may be included in the power generation information.

In addition, when the reference point is selected as the sunrise time and monitoring is requested at the sunset time, the weekly power generation amount and the corresponding power generation amount may be included in the generation amount information.

In addition, when the reference point is selected as the point in time when the generation amount is measured/collected immediately before and monitoring is requested, the generation amount information may include the current generation amount (current output) and the generation amount according to the generation amount collected immediately before the reference point.

The information providing unit 220 may provide the generation amount information together with weather information used when adjusting the target generation amount.

At this time, the information providing unit 220, instead of the weather information, is generated by the environment detection sensor built in the RTU equipment, using at least one of the detection information of atmospheric temperature and module temperature, horizontal and vertical insolation, and wind speed. Alternatively, the environment of the solar power plant may be determined by comparing the weather information with the sensing information, and generation amount information may be provided accordingly.

Accordingly, the monitoring terminal can grasp the power generation performance and normal operation of the photovoltaic power plant at a glance simultaneously with the weather information at a glance, without the need to separately search for weather information that has affected the power generation control of the photovoltaic power plant. .

For example, the information providing unit 220 varies the color, size, boldface, pop-up window, icon, etc. for displaying the generation amount information according to the weather information affecting the power generation control of the solar power plant, and provides weather information in the monitoring terminal. It is possible to intuitively grasp the correlation between the power generation and the actual power generation.

In addition, the power generation control unit 240 is specialized in the region where the corresponding solar power plant is located, and accurately analyzes the power generation required according to weather information by the deep learning technique, so that it is possible to accurately determine the target power generation amount to be adjusted in the subsequent generation control .

In addition, the monitoring terminal may change the menu to be provided on the basic screen 410 by selecting 'add screen' 408 . For example, when adding a 'calendar view' 404 to the basic screen 410 instead of deleting the inverter information 412 from the monitoring terminal, the information providing unit 220 provides power generation information 411 and weather information. A calendar (refer to 510 of FIG. 5 ) displaying together may be provided as the basic screen 410 .
