3 is a view showing an internal configuration module of the integration / operation management unit according to an embodiment of the present invention.

The integrated / operational management unit is connected to the power generation information collection server, the security / disaster prevention collection server, the image management server, and the authentication server, and can collectively collect, manage, and control various types of information generated from renewable energy power plants. .

Referring to FIG. 3, the generation information collection server 300 as an internal configuration module belonging to the integration / operation management unit includes an internal module linkage unit 310, a state monitoring / failure analysis unit 320, an event generation unit 330, The database manager 340, the database manager 350, and the display manager 360 may be configured.

First, the internal module linkage unit 310 collects power generation information from power generation facilities provided in a renewable energy power plant. The power generation equipment and the power generation information may correspond to each other, and the internal module linkage unit 310 may include a communication link receiving corresponding power generation information from the power generation facility.

The power generation information may include information on voltage and current of each power generation facility. The internal module linking unit 310 may collect power generation information about a grid R phase voltage / current, a grid S phase voltage / current, and a grid T phase voltage / current according to the grid.

In addition, the internal module linking unit 310 may collect power generation information on the overall status of new and renewable energy power plants such as active power, reactive power, today's power generation, cumulative power generation, generation amount, and the like.

In another embodiment, the internal module linkage unit 310 may collect power generation information regarding solar radiation, temperature, humidity, and the like in relation to the external environment of the power generation facility. At this time, the internal module linkage unit 310 may collect power generation information on whether the power generation equipment is operating or not. In some cases, the internal module linkage unit 310 may collect power generation information related to the external environment of the power generation facility through the method / disaster prevention collection server 300 for controlling and monitoring the sensor.

When there is a video request from the manager, the internal module linkage unit 310 may collect power generation equipment and collect power generation information on external intrusions or harmful substances. The image may be an image obtained from a camera apparatus installed adjacent to each power generation facility. In some cases, the internal module linkage unit 310 may collect an image of the power generation facility through the image management server 230 that controls and monitors the imaging means.

The manager of renewable energy power plant can receive the power generation status in real time through the manager terminal at a remote location of the power plant.

The state monitoring / failure analysis unit 320 may monitor the state of the power generation facility by analyzing the power generation information.

That is, the state monitoring / failure analysis unit 320 may determine whether the output of the power generation facility is normal. For example, the state monitoring / failure analysis unit 320 may determine the generation amount of the power converted by the power generation facility and determine whether the set reference value is exceeded. In this case, the state monitoring / failure analysis unit 320 may determine the amount of power generated by the power sensor added to the individual power generation equipment from the power generation information.

In addition, the state monitoring / failure analysis unit 320 analyzes the power generation information to monitor the state of the power generation equipment, security / disaster prevention collection server 220, video management server 230, and authentication server 240 of The state of the monitored power generation equipment is verified by using the additional information input from at least one, and the state of the monitored power generation equipment is confirmed, or the state of the monitored power generation equipment is invalidated and the state of the power generation equipment is remonitored. can do.

For example, the state monitoring / failure analysis unit 320 receives an error rate of the voltage and current measured by the power sensor as additional information from the crime prevention / disaster prevention collection server 220 and determines whether an error rate of a predetermined reference value or more continues for a predetermined period of time. As a result, the state of the monitored power generation facility may be verified to confirm the state of the monitored power generation facility or the state of the monitored power generation facility may be invalidated to re-monitor the state of the power generation facility.

As another example, the status monitoring / failure analysis unit 320 verifies whether the response is transmitted by transmitting a message for checking the status to a corresponding power generation facility monitored in an abnormal state, thereby verifying the state of the monitored power generation facility and monitoring the monitoring. The state of the power generation facility can be re-monitored by determining the state of the generated power generation facility or by invalidating the monitored state of the power generation facility.

As another example, the state monitoring / failure analysis unit 320 detects an unrelated person, dust, impact, etc. approaching the power generation facility from an image of the power generation facility provided by the image management server 230, thereby monitoring the generated power generation. The state of the facility may be verified to determine the state of the monitored power generation facility or the state of the monitored power generation facility may be invalidated to re-monitor the state of the power generation facility.

In the state monitoring, the state monitoring / failure analysis unit 320 may store the set reference value for the solar radiation, temperature, humidity.

In addition, the state monitoring / failure analysis unit 320 may maintain a database for checking whether the power generation facility is abnormal compared to the reference value. That is, the state monitoring / failure analysis unit 320 may set and store a reference value of each generation information in the database.

The remote service unit 350 may provide the power generation information to a manager terminal of a remote place. For example, the remote service unit 350 may display the voltage and current of the power generation facility on the manager terminal to provide a flow of overall power generation information. The power generation information may be converted into an SMS or the like for transmission to the manager terminal. The manager can check the time-phase development information in the graph through the manager terminal.

The manager terminal may receive the power generation information through the Internet network and execute an application that can access the power generation information collection server 300 to request the power generation information and detailed monitoring data.

When the plurality of generation information is collected within the same time, the display manager 360 may arrange the plurality of generation information collected on one screen in consideration of the power generation facility and display the same on the manager terminal. That is, the display manager 360 may serve to simultaneously or sequentially display the plurality of generation information on, for example, a 7-inch display screen.

In this way, the display manager 360 may provide an environment that enables the manager who has confirmed the manager terminal to recognize the status of the multiple power generation facilities at the same time.

The event generator 330 generates a fault event when the power generation facility is in an abnormal state as a result of the monitoring of the state monitor / failure analyzer 320. In this case, the remote service unit 350 may transmit an alarm message for the failure event or an image of the power generation facility to the manager terminal. The remote service unit 350 may transmit an alarm message including information on the time when the failure occurred and the type of power generation equipment in which the failure occurred.

The failure occurrence processing of the event generator 330 and the restoration procedure by the database manager 340 described below are as follows.

1. Detect abnormal condition caused by failure.

2. Generate a fault event.

3. Confirm failure event.

4. Check the data of all power generation facilities, associated systems, and images in the order of time and determine the cause.

; For example, when the contents of the fault event (# 01 inverter STOP) are clicked, the power generation information collection server 300 may check all power generation equipment information before and after the time when the # 01 inverter is stopped (changes according to a setting). Through this, the power generation information collection server 300 searches for crime prevention / disaster prevention and image data before stopping, and is the reason why the STOP is stopped due to an error of the power generation equipment, whether it is an intentional STOP of an external invader, or a STOP by fire / immersion Recognition can be determined. That is, the generation information collection server 300 may check all the complex contents in time at the time of failure confirmation.

5. Failure Handling-Onsite dispatch, restore command

As an example of such restoration, the stored data of the set-top may be stored (backed up) once a day in the IDC server, or if the data of the set-top flows, the data of the set-top may be restored with the data of the IDC.

In addition, in the embodiment, the remote service unit 350 may generate a symbol indicating the state of the power generation equipment, and transmit to the manager terminal. For example, the remote service unit 350 may generate a 'sun symbol' for the power generation facility A determined to be in a normal state and transmit the generated sun symbol to the manager terminal. Similarly, the remote service unit 350 may generate a 'non-cloud symbol' for the power generation facility B that is determined to be in an abnormal state as a result of the monitoring, and transmit the generated non-cloud symbol to the manager terminal.

The manager may receive the alarm message through the manager terminal and check the type and location of the power generation equipment in which the failure occurs. The manager may determine the cause of the failure by referring to the image and the power generation information for the power generation facility.

The remote service unit 350 calls the site dispatch system to the power generation facility in association with the failure event. For example, when an unauthorized intrusion of the power generation facility is detected, the remote service unit 350 may call the field dispatch system to dispatch a security company employee to the site.

The database manager 340 may back up the power generation information collected in a selected time range on the basis of the time when the failure event occurs.

The database manager 340 may back up the power generation information collected in a first period including the time when the failure event occurs when the power generation information is collected during a cycle according to the arrival of the cycle. The first period may end at the same time as when the failure event occurred. The database manager 340 may back up the power generation information collected in the first cycle period to maintain the power generation information constantly.

The database manager 340 backs up the power generation information collected in a second cycle period that is started or ended closest to the time when the failure event occurs. For example, the internal module linkage unit 310 may collect the power generation information at a period of 1 minute. The failure event may occur when the internal module linkage unit 310 completes the collection of the power generation information in the second period and is in a standby state. The database manager 340 may backup the power generation information to maintain the state of the most recent power generation facility.

The database manager 340 backs up the power generation information through an internet data center (IDC). The IDC may provide a space and a facility for operating a server or a communication system and connect it to a network.

The IDC may receive a generation information transmission request for fault recovery from the database manager 340. Through the IDC, continuity of important generation information can be guaranteed.

The database manager 340 may transmit the same power generation information generated by each power generation facility to the IDC, or select and transmit power generation information of high importance.

The IDC can duplicate the storage of the power plant. To this end, the storage of the power plant and the storage of the IDC may be compatible with each other.

When the IDC transmits a response message including whether to copy the changed power generation information to the power generation facility, the database manager 340 may complete the backup of the power generation information.

The database manager 340 normalizes the generation information in a predetermined format. The IDC may standardize the power generation information to exchange power generation information generated from various power generation facilities. For example, the database manager 340 may match units of values for power measured at each power generation facility.

The database manager 340 restores the abnormal state by using the backup generation information.

The database manager 340 may restore the abnormal state by copying the backup power generation information to a power generation facility.

The power generation information collection server 300 may control the power generation facility by maintaining information on the countermeasure for each situation of the abnormal state. For example, the power generation information collection server 300 may transmit a control command for controlling temperature and humidity inside the power generation facility to the power generation facility.

The generation information collection server 300 may control a generation facility in which an abnormal state is detected by receiving a control command from an administrator. The manager may analyze the power generation information through the manager terminal to determine the cause of the failure, and input a control command of the power generation equipment.

The generation information collection server 300 may include a means for correcting the error in case of a handicapped person regarding the error of the generation information, and receive the correction value from the administrator to restore the failure.

The power generation information collection server 300 may generate a temporary power by operating an alternative means for when power is not produced from the power generation information.

The power generation information collection server 300 backs up the power generation information collected from the state restored power generation facilities regardless of occurrence of the failure event.

4 is a diagram for explaining an example of determining a time range for backup according to the present invention.

In FIG. 4A, when power generation information is continuously collected from a power generation facility, determining a time range for backing up is illustrated.

The administrator can predetermine the time the backup operation is maintained, and the integrated integrated renewable energy plant management device can determine the time range based on the time of occurrence of the failure event.

For example, if the time designated by the administrator is 10 minutes and the occurrence time of the failure event is AM 2:30, the integrated integrated renewable energy plant management device is AM 2 at AM 2:20, which is 10 minutes before AM 2:30. Up to: 30 can be determined as the time range for backing up. Accordingly, the integrated integrated renewable energy plant management apparatus may back up the generation information collected from the determined time range AM 2:20 to AM 2:30 through IDC.

In addition, in FIG. 4B and FIG. 4C, when generating power generation information is discontinuously collected from a power generation facility, determining the time range to back up is illustrated.

In FIGS. 4B and 4C, power generation information is collected while having a period of 10 minutes (AM 1:50 to AM 2:00, AM 2:05 to AM 2:15).

First, as shown in FIG. 4B, as a fault event occurs during the 10 minute period (AM 2:10), a cycle period including a time point at which the fault event occurs, that is, AM 2:05 to AM 2: Up to 15 can be determined as the time range for backing up. Accordingly, the integrated integrated renewable energy plant management device may back up the generation information collected from the determined time range AM 2:05 to AM 2:15 through IDC.

In addition, (c) of FIG. 4 illustrates that a failure event occurs for 5 minutes of waiting time between the periods of the 10 minute period (AM 2:01), and thus, AM 1 which is closest to the time point at which the failure event occurs is generated. From: 50 to 2:00 AM can be determined as the time range for the backup. Accordingly, the integrated integrated renewable energy plant management device may back up the generation information collected from the determined time range AM 1:50 to AM 2:00 through IDC.

According to an embodiment, the integrated integrated renewable energy plant management device may verify and monitor the state of the monitored power generation equipment by using additional information input from at least one of a security / disaster prevention collection server, an image management server, and an authentication server. The state of the power generation facility can be re-monitored by determining the state of the generated power generation facility or by invalidating the monitored state of the power generation facility.

For example, even when an abnormal state is monitored through analysis of power generation information, when additional information regarding a failure of an access sensor inputted from a method / disaster prevention collection server is inputted, an integrated integrated renewable energy plant management apparatus is configured to monitor the abnormality. It is possible to collect new generation information from the power plant while invalidating the condition.

The integrated integrated renewable energy plant management device standardizes the power generation information in a predetermined format. The IDC may standardize the power generation information to exchange power generation information generated from various power generation facilities. The integrated integrated renewable energy plant management unit can match the unit of value for the power measured at each plant.

In addition, the integrated integrated renewable energy plant management apparatus may transmit an alarm message for the failure event or an image of the power generation facility to the manager terminal (570). The integrated integrated renewable energy plant management device may transmit an alarm message including information on the time when the failure occurred and the type of power generation equipment in which the failure occurred. The integrated integrated renewable energy plant management apparatus may generate a symbol representing the state of the power generation facility and transmit the generated symbol to the manager terminal.

The integrated integrated renewable energy power plant management device calls on-site dispatch system to the power generation facility in association with the failure event. For example, when an unauthorized intrusion of the power generation facility is detected, the integrated integrated renewable energy plant management device may call the field dispatch system to dispatch security company personnel to the site.

In another embodiment, the integrated integrated renewable energy plant management device may restore the abnormal state by using the backup power generation information.
