[0067] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0068] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant regulations.

[0069] In one embodiment, Figure 1 As shown, a method for handling unit faults is provided. This embodiment uses the method applied to a server as an example for illustration. It is understandable that the method can also be applied to a terminal, and can also be applied to a system including a server and a terminal, and is implemented through the interaction between the server and the terminal; wherein the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services; the terminal can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, etc. In this embodiment, the method includes the following steps:

[0070] Step S102, obtaining the operation data flow of the unit in real time.

[0071] There are multiple units in a power plant, and each unit consists of multiple equipment.

[0072] Among them, the operation data stream of the unit includes the time series of the operation data of each device when the unit is running; further, the operation data specifically refers to the status signal of the equipment. Taking the generator set as an example, the status signal includes the water inlet valve opening signal, the water inlet valve closing signal, the generator switch opening signal, the generator switch disconnection signal, etc.

[0073] Specifically, the present application installs various types of sensors at key locations of each device of the unit, and the various sensors report the collected status signals in the form of operating data streams to the server in real time, so that the server can obtain the operating data streams of the unit in real time.

[0074] Step S104, determining the operating condition of the unit based on the operating data flow of the unit, identifying the target operating data flow under the operating condition from the operating data flow, and displaying the target operating data flow in real time.

[0075] Among them, the operating condition is the current operating condition of the unit; the operating condition is used to characterize the state and function of the unit during operation. The operating conditions in this application include but are not limited to power generation conditions, pumping conditions, pump conditions, etc.

[0076] Among them, there are multiple operating data streams in the present application, each corresponding to an operating data item; for example, the water inlet valve opening signal is an operating data item, and the time series of the water inlet valve opening signal is the operating data stream under the operating data item "water inlet valve opening signal"; for another example, the generator switch opening signal is an operating data item, and the time series of the generator switch opening signal is the operating data stream under the operating data item "generator switch opening signal".

[0077] Among them, different operating conditions focus on different operating data items, that is, different operating conditions correspond to different operating data items, and the target operating data flow under the operating condition refers to the operating data flow under the operating data item corresponding to the operating condition.

[0078] Specifically, the server determines the current operating condition of the unit based on the operating data flow of the unit and obtains the operating condition of the unit; then, the server determines at least one operating data item corresponding to the operating condition, and determines the operating data flow under at least one operating data item corresponding to the operating condition among multiple operating data flows as the target operating data flow of the unit under the operating condition, and displays each target operating data flow in real time through the front end of the server.

[0079] In a specific application, the server displays the target operation data flow, which may be a real-time display of specific data values, or a real-time display of a curve representing changes in the target operation data flow.

[0080] Step S106, determining the presence of a fault in the unit based on the target operation data flow, and in the case where a fault exists in the unit, identifying fault operation data associated with the fault from the operation data flow.

[0081] Specifically, the server determines whether a fault occurs in the unit based on each target operation data stream, thereby obtaining the fault status of the unit, and when a fault occurs in the unit, determines at least one fault operation data stream associated with the fault from each target operation data stream.

[0082] Step S108, performing fault diagnosis on the unit based on the fault operation data stream to obtain the fault type and the fault point corresponding to the fault in the unit.

[0083] Specifically, the server performs fault diagnosis on the unit based on each fault operation data stream to obtain a fault diagnosis result of the unit; wherein the fault diagnosis result of the unit at least includes the fault type of the fault occurring in the unit and the fault point where the fault occurs in the unit.

[0084] Step S110, displaying the fault type, fault point and fault operation data flow in real time.

[0085] Specifically, the server displays the fault type of the fault occurring in the unit, the fault point of the fault, and the fault operation data flow associated with the fault in real time through the front end of the server.

[0086] In a specific application, the server displays the fault operation data flow, which may be a real-time display of specific data values, or a real-time display of a curve representing changes in the fault operation data flow.

[0087] In this step, by displaying the fault type, fault point and fault operation data flow in real time, it is easy for technicians to restore the specific situation at the fault site.

[0088] In the above-mentioned unit fault handling method, first, the server obtains the operating data stream of the unit in real time; then, the server determines the operating condition of the unit based on the operating data stream of the unit, and identifies the target operating data stream under the operating condition from the operating data stream, and displays the target operating data stream in real time; then, the existence of the unit's fault is determined based on the target operating data stream, and when the unit has a fault, the fault operating data associated with the fault is identified from the operating data stream; then, the unit is diagnosed based on the fault operating data stream to obtain the fault type and the fault point corresponding to the fault in the unit; finally, the server displays the fault type, fault point and fault operating data stream in real time. In this way, based on the operating data stream of the unit, the server can determine the operating conditions of the unit, and then identify the target operating data under the operating conditions from the operating data stream and display it in real time; based on the target operating data stream, the server can determine whether the unit has a fault. If there is a fault, it further diagnoses the unit based on the faulty operating unit associated with the fault in the target operating data stream to obtain the fault type and fault point. Finally, by displaying the fault type, fault point and fault operating data in real time, the server can facilitate the technical personnel to grasp the fault situation of the unit in a timely and real-time manner; the unit fault handling method based on the above process can perform real-time fault diagnosis on the unit by processing the operating data stream, and can provide real-time fault warnings for the unit by displaying the fault type, fault point and fault operating data in real time, so that the technical personnel can promptly operate and maintain the faults of the unit, thereby reducing the lag in unit fault handling.

[0089] In an exemplary embodiment, there are multiple operation data flows, and each operation data flow corresponds to an operation data item.

[0090] like Figure 2 As shown, the above step S104, identifying the target operation data flow under the operation condition from the operation data flow, specifically includes the following steps:

[0091] Step S202, querying the correspondence between the predetermined operating conditions and the operating data items, and determining at least one target operating data item that has a correspondence with the operating conditions.

[0092] Step S204, identifying the operation data flow under each target operation data item from the multiple operation data flows, and obtaining the target operation data flow under the operation condition.

[0093] In a specific application, the present application also has the following contents to determine the corresponding relationship between the operating conditions and the operating data items:

[0094] For each operating condition, the server obtains the operating data stream when the unit fails under the operating condition; the server analyzes the operating data stream when the unit fails under the operating condition based on the principal component analysis method, and under the operating condition, determines the operating data items that can characterize whether the unit fails, and obtains the operating data items corresponding to the operating condition; based on the operating data items corresponding to each operating condition, the server determines the correspondence between the operating condition and the operating data items, and obtains the correspondence between the predetermined operating condition and the operating data items.

[0095] Specifically, based on the current operating condition of the unit, the server queries the correspondence between the predetermined operating condition and the operating data item, and obtains at least one operating data item that has a corresponding relationship with the operating condition, namely, the target operating data item; then, the server uses the operating data flow under each target operating data item in the multiple operating data flows as the target operating data flow under the current operating condition of the unit.

[0096] In this embodiment, based on the correspondence between predetermined operating conditions and operating data items, the server can obtain target operating items that can characterize whether a fault occurs in the unit under the current operating conditions of the unit, and further obtain target operating data streams that can characterize whether a fault occurs in the unit.

[0097] In an exemplary embodiment, Figure 3 As shown, the above step S106, determining the fault status of the unit based on the target operation data flow, and identifying the fault operation data associated with the fault from the operation data flow when the unit has a fault, specifically includes the following steps:

[0098] Step S302, obtaining the historical normal operation data flow of the unit under each target operation data item.

[0099] Step S304: for each target operation data item, determine first difference information between the target operation data flow under the target operation data item and the historical normal operation data flow under the target operation data item.

[0100] Step S306: When the first difference information corresponding to any target operation data item meets the preset fault judgment condition, it is determined that the unit has a fault.

[0101] Step S308: determining the target operation data item whose corresponding first difference information meets the preset fault determination condition as a faulty operation data item.

[0102] Step S310: determine the target operation data flow corresponding to the fault operation data item among the multiple target operation data flows as the fault operation data flow associated with the fault.

[0103] The preset fault determination condition refers to being greater than or equal to the first difference information threshold.

[0104] Specifically, the server first obtains the historical normal operation data flow of the unit under each target operation data item; then, for each target operation data item, the server computer group calculates the first difference information between the target operation data flow and the historical normal operation data flow under the target operation data item; then, the server determines that the unit does have a fault when there is any target operation data item in each target operation data item whose first difference information is greater than or equal to the first difference information threshold, that is, when the first difference information corresponding to any target operation data item is large; then, the server determines each target operation data item whose corresponding first difference information is greater than or equal to the first difference information threshold as a faulty operation data item, and then, the server determines the target operation data flow under each faulty operation data item in multiple target operation data flows as a faulty operation data flow associated with the fault.

[0105] In a specific application, there may be multiple historical normal operation data streams for each target operation data item of the unit. In the case where there are multiple historical normal operation data streams under the target operation data item, the server may respectively calculate the difference information between the target operation data stream under the target operation data item and each historical normal operation data stream under the target operation data item, and then obtain the first difference information based on the average value of the difference information; the server may also determine the benchmark normal operation data stream under the target operation data item based on the multiple historical normal operation data streams under the target operation data item, and then calculate the difference information between the target operation data stream under the target operation data item and the benchmark operation data stream to obtain the first difference information.

[0106] In practical applications, each operation data stream is a type of status signal of the unit within a certain length of time; therefore, the server can compare the target operation data stream and the historical normal operation data stream belonging to the same target operation data item, and determine the status signals that are different or have large differences between the two, thereby obtaining the difference information between the two.

[0107] In this embodiment, based on the historical normal operation data flow of the unit under each target operation data item, the server can determine whether there is an abnormality in the operation data flow of the unit under each target operation data item, thereby determining whether there is a fault in the unit, and can determine the faulty operation data flow that is associated with the fault from the multiple operation data streams of the unit.

[0108] In an exemplary embodiment, Figure 4 As shown, the above step S108, based on the fault operation data flow, performs fault diagnosis on the unit to obtain the fault type and the fault point corresponding to the fault in the unit, specifically includes the following steps:

[0109] Step S402, obtaining the historical fault operation data stream of the unit under each fault operation data item.

[0110] Step S404: for each fault operation data item, determine second difference information between the fault operation data flow under the fault operation data item and each historical fault operation data flow under the fault operation data item.

[0111] Step S406: determine the historical fault operation data stream whose corresponding second difference information meets the preset fault location condition as the reference fault operation data stream under the fault operation data item.

[0112] Step S408: taking the historical fault point corresponding to the reference fault operation data stream under the fault operation data item as a fault point corresponding to the fault in the unit.

[0113] Step S410, determining the fault type of the fault based on the fault points corresponding to the fault in the unit.

[0114] Among them, under each fault operation data item, the unit has multiple historical fault operation data streams corresponding to different fault types and different fault points. In a specific application, the unit can have multiple historical fault operation data streams under the same fault operation data item, the same fault type and the same fault point.

[0115] The preset fault location condition refers to having the minimum second difference information.

[0116] Different fault types correspond to different fault points, and the server can determine the fault type based on the fault point.

[0117] Specifically, the server first obtains the historical fault operation data stream of the unit under each fault operation data item; then, for each fault operation data item, the server respectively calculates the second difference information between the target operation data stream of the unit under the fault operation data item and each historical fault operation data stream under the fault operation data item; then, the server counts the second difference information corresponding to each historical fault operation data stream, and determines the historical fault operation data stream with the smallest second difference information among each historical fault operation data stream as the reference fault operation data stream under the fault operation data item, and determines the historical fault point corresponding to the reference fault operation data stream as a fault point in the unit corresponding to the fault occurring in the unit; finally, the server obtains the fault type of the fault based on the correspondence between the fault type and the fault point, and the fault points in the unit corresponding to the fault occurring in the unit.

[0118] In practical applications, each operation data stream is a type of status signal of the unit within a certain length of time; therefore, the server can compare the fault operation data stream and the historical fault operation data stream belonging to the same fault operation data item, and determine the status signals that are different or have large differences between the two, thereby obtaining the difference information between the two.

[0119] In this embodiment, for each fault operation data item, the server can obtain a fault point of the unit based on a reference fault operation data stream that has the smallest difference with the fault operation data stream of the unit under the fault operation data item among various historical fault operation data streams under the fault operation data item; the server can obtain the fault type of the unit based on various fault points of the unit and the corresponding relationship between the fault type and the fault point.

[0120] In an exemplary embodiment, the unit fault handling method provided in the present application further includes the following contents: according to the fault operation data flow and the fault point corresponding to the fault operation data, the fault operation data flow is determined as a newly added historical fault operation data flow.

[0121] Specifically, after obtaining the fault point corresponding to the fault operation data stream, the server adds the fault operation data stream to the historical fault operation data stream based on the fault operation data stream and the corresponding fault point.

[0122] For example, multiple historical fault operation data flows and their corresponding fault points are stored in the fault library. The server adds the fault operation data flows and their corresponding fault points to the fault library to obtain newly added historical fault operation data flows.

[0123] In this embodiment, the unit fault handling method provided by the present application specifically also includes the following contents: when there is no fault in the unit, the target operation data flow is used as a newly added historical normal operation data flow.

[0124] Specifically, when there is no fault in the unit, the server adds the target operation data flow to the historical normal operation data flow.

[0125] For example, multiple historical normal operation data flows are stored in a normal library. The server adds the target operation data flow to the normal library to obtain the newly added target operation data flow.

[0126] In this embodiment, the server can continuously optimize the accuracy of the fault point location process and the accuracy of the fault determination process by updating and maintaining the historical fault operation data stream and the historical normal operation data stream in real time, thereby improving the reliability of unit fault handling.

[0127] In an exemplary embodiment, after the above step S110, in which the fault type, fault point and fault operation data flow are displayed in real time, the following contents are specifically included: when a reset instruction is received, the current operation data flow of the unit is used as a new operation data flow, the operating condition of the unit is determined based on the operation data flow of the unit, and the target operation data flow under the operating condition is identified from the operation data flow, and the step of displaying the target operation data flow in real time is included.

[0128] Specifically, after the operation and maintenance personnel repair the unit's fault, they can send a reset command to the server; the server receives the reset command, uses the unit's current operating data flow as the new operating data flow, returns to step S104, determines the unit's operating conditions based on the unit's operating data flow, and identifies the target operating data flow under the operating conditions from the operating data flow, and displays the target operating data flow in real time, thereby resetting the information displayed on the server front end and re-displaying the current target operating data flow in real time.

[0129] In specific applications, a reset button is provided on the front end of the server. By triggering the reset button, the operation and maintenance personnel can send a reset instruction to the server.

[0130] In this embodiment, the server can update the displayed information by responding to the reset instruction and re-displaying the new target operation data stream in real time, so as to facilitate the technical personnel to grasp the operation status of the unit in a timely and real-time manner.

[0131] In an exemplary embodiment, if Figure 5 As shown, another method for handling unit failure is provided, which is described by taking the method applied to a server as an example, and includes the following steps:

If there is a fault, the server further diagnoses the unit based on the faulty operation unit associated with the fault in the target operation data stream to obtain the fault type and fault point. Finally, by displaying the fault type, fault point and fault operation data in real time, the server can facilitate the technical personnel to grasp the fault situation of the unit in a timely and real-time manner; the unit fault handling method based on the above process can perform real-time fault diagnosis on the unit by processing the operation data stream, and can provide real-time fault warning to the unit by displaying the fault type, fault point and fault operation data in real time, so as to facilitate the technical personnel to operate and maintain the fault of the unit in time, thereby reducing the lag of unit fault handling.

[0147] 4. After the on-duty personnel have handled the fault, they press the reset signal to reset the displayed data.

[0148] In this embodiment, by displaying fault data and fault causes, it can help the on-duty personnel to restore the fault scene, provide strong support for fault diagnosis and analysis, strengthen the status monitoring of the unit, and greatly improve the efficiency and accuracy of fault analysis.
