1 is an exemplary view of a hydro-powered app-based fault recovery system according to the present invention. The system is a system that provides easy troubleshooting procedures for a power plant maintained by a manager who produces electricity in a hydro power plant. This is the system 100 for transmitting the current status of the power generation facility 200 to the manager and the recording medium 300 and the system 100 interlocked with the system 100 by storing the past information of the power generation facility 200 It may be made of a terminal 400 in conjunction with and provides information of the power generation facility 200 to the manager.

The failure recovery system 100 plays a pivotal role of determining a failure of the power generation facility 200 and guiding a recovery procedure to a manager, and an abnormality detection unit interlocking with the power generation facility 200 to determine whether there is an error. 110, an analysis module 120 for analyzing a failure of the power generation facility 200 to determine a failure type, an alarm transmission module 130 linked with the terminal 400 to transmit failure information to a manager by text, and The recording medium 300 and the terminal 400 may include a maintenance request module 140 in charge of the communication for transmitting and receiving information.

The abnormality detection unit 110 is a part for determining whether there is an abnormality in the operation of the power generation equipment 200, and checks whether or not a failure of the equipment based on the information on the current state provided by the power generation equipment 200. do. At this time, if the abnormality detection unit 110 determines that the state of the power generation facility 200 is abnormal, a detailed analysis of the failure state is performed.

The analysis module 120 is a module for analyzing abnormal operation of the power generation facility 200 determined by the abnormality detection unit 110. The analysis module 120 determines a category of a failure and analyzes the cause thereof.

The alarm transmission module 130 is a part for transmitting the contents of the failure type analyzed by the analysis module 120 to the terminal 400 held by an administrator, and transmits the system 100 and the terminal 400. This part is linked. The administrator may grasp the state of the power generation facility 200 through the text content transmitted from the alarm transmission module 130.

The maintenance request module 140 interlocks with the recording medium 300 to secure a recovery procedure for a current failure based on the past history and information of the power generation facility 200, and also interlocks with the terminal 400. This part provides the administrator with the secured recovery procedure.

To this end, the maintenance request module 140 receives information stored in the past, such as a past history, drawings, and circuit diagrams, from the recording medium 300, and transmits a recovery procedure to the terminal 400.

In order for the system 100 to check the status of the power generation facility 200 from time to time, the power generation facility 200 transmits a plurality of specification values for the current state to the system 100.

Therefore, the measurement unit 210 which measures a plurality of specifications for the parts of the power generation facility 200 arbitrarily designated by an administrator, and the measurement value transmitter which transmits the values measured by the measurement unit 210 to the system 100. 220.

In addition, the system 100 is linked with the recording medium 300 in which a plurality of pieces of information about the power generation facility 200 are stored, thereby comprehensively determining the present and past histories of the power generation facility 200, thereby making it more reliable. This high failure determination result can be derived.

The recording medium 300 stores the failure and maintenance history 310 of the power generation facility 200, the mechanical drawings and the electrical circuit diagram 320, and at the same time the normality of the power generation facility 200 designated by an administrator. When the operation is made, the specification value to be measured by the measurement unit 210 is stored, so that the abnormality detection unit 110 may be used as a reference value for determining the abnormality of the power generation facility 200.

The terminal 400 is a medium that delivers the information analyzed by the system 100 to the administrator, and provides information on what kind of failure categories the administrator previously classified according to a specific criterion, and recovers the information. The procedure can be communicated.

Information about the failure may be received as a notification text, and the information about the failure may be searched through a search engine of an application to establish a recovery procedure.

Figure 2 is an exemplary view showing an embodiment of a fault recovery procedure using a hydro-powered app-based fault recovery system according to the present invention. In the normal operation step (S110) in which the power generation equipment 200 operates normally, the measurement unit 210 measures a plurality of specification values at a predetermined period set by an administrator, and measures the system by the measured value transmitter 220. Is passed to 100.

The abnormality detecting step (S120) detects abnormal operation of the power generation facility 210 based on the measurement value received by the abnormality detection unit 110 from the measurement value transmitter 220.

When an abnormality is detected in the abnormality detecting step S120, the system 100 receives a past failure and maintenance history 310 from the recording medium 300, thereby resulting in a simple component aging of a part whose failure is determined. It enters the history analysis step (S130) for analyzing whether or not the cause. At this time, if it is determined that the failure due to aging, the system 100 is a transmission step (S131) for transmitting the information about the failure as a text to the terminal 400 and the recovery progress step (S132) that the administrator proceeds to recovery. The cause of the fault can be solved by

However, in the history analysis step (S130), if it is derived from the analysis result value that is not a failure due to component aging, a plurality of specification values received from the measured value transmitter 220 is analyzed in detail in the analysis module 120 The analysis and determination step S140 of deriving the cause of the failure is performed.

If the analysis of the cause of the failure is finished through the analysis and determination step (S140), the alarm character transmission step (S150) for transmitting the information on the failure to the terminal 400 is entered. This transfers the result analyzed by the analysis module 120 to the terminal 400 through the alarm transmission module 130.

The administrator who checks the contents of the cause of the failure through the text through the application search (S160) for searching the analysis procedure through the search engine of the application embedded in the terminal 400, the system 100 received the search content ) Is linked with the recording medium 300 to perform a recovery procedure guide step (S170) of transmitting a recovery procedure to the terminal 400.

Thereafter, the administrator who checks the recovery procedure through the terminal 400 executes the step S180 of proceeding with the recovery procedure. When the recovery is completed and the power plant 200 is normally operated, the system 100 By performing the history storage step (S190) of storing the contents and maintenance history of the failure that the power plant 200 has abnormally operated in the recording medium 300, to complete the recovery procedure for the power plant 200 do.

Figure 3 is an exemplary view showing another embodiment of a troubleshooting procedure using a hydro-powered app-based failure recovery system according to the present invention. As in the above embodiment, in the normal operation step (S210) in which the power generation facility 200 operates normally, the measured value measured by the measurement unit 210 at regular intervals is measured through the measurement value transmitter 220. The system 100 is transferred to the system 100 and enters the abnormality detecting step S220 of detecting abnormal operation of the power generation facility 200 based on the specification value. This may be determined by the abnormality detecting unit 110, and the reference value for determining this may be a normal specification value recorded in the recording medium 300.

At this time, if abnormal operation is detected, it is determined whether the abnormal specification value is generated in the measurement unit 210 of which part of the power generation facility 200. First, a first determination step (S230) is performed to determine whether a generator part in charge of power generation of the power generation facility 200 is a major cause of failure. This can be more efficiently performed by the system 100 to determine the cause of the failure by limiting the range of the measurement unit 210 in the process of collecting a plurality of specifications values.

If the measured value measured by the measuring unit 210 installed in the generator is in the normal range, the system 100 after analyzing the measured value of the measuring unit 210 of the other parts except the generator comprehensively abnormal The part is identified and the corresponding alarm text is transmitted to the terminal 400 of the manager.

However, if the range of the measured value measured by the measuring unit 210 of the generator does not belong to the normal range, it is determined that the abnormal operation is performed due to a failure occurred in the generator and goes through the second determination step (S240).

The second determination step S240 is a step of determining whether the generator is a mechanical failure or an electrical failure. This is performed by the analysis module 120 based on the drawing and circuit diagram 320 of the recording medium 300. If it is a mechanical failure, the analysis module 120 may determine whether there is an abnormality based on a drawing of the generator, and may determine based on a circuit diagram if an abnormal operation is made electrically. You can also determine whether it is a light fault or a serious fault.

After the analysis, the terminal 400 transmits the text of the failure in text.

Thereafter, the administrator executes an application search step (S250) in which the administrator searches through the application of the terminal 400, and the system 100 transmits a description of the failure from the recording medium 300. A recovery procedure guide step (S260) of displaying a corresponding recovery procedure to the terminal 400 is performed.

Based on this, the manager performs a repair procedure progress step (S270) of performing maintenance on the power generation facility 200, and when the maintenance of the power generation facility 200 is completed and restores normal operation, breakdown and maintenance contents are reported. The recovery procedure is completed by performing a history storing step (S280) of storing the recording medium 300.
