Therefore, early warning methods based on manual analysis of the operating data of power equipment have low timeliness. Summary of the Invention

[0036] Among them, the power equipment operation monitoring system is used to monitor and provide early warnings for various power equipment under multiple equipment types. There are multiple power equipment under each equipment type, and each equipment type has corresponding multiple equipment measuring points.

[0037] The power equipment operation monitoring system has multiple system accounts.

[0038] The equipment includes various types such as generators, turbines, inlet valves, technical water supply pumps, excitation systems, speed governors, SFC (Static Frequency Converter), GCB (Generator Circuit Breaker), GIS (Gas Insulated Switchgear), main transformers, and outlet busbars.

[0039] Among them, the measuring point is the way to organize the time-series data in the power system in the power field. One measuring point corresponds to one data item. For example, taking the power equipment as a water turbine, the water guide oil level of the water turbine is a measuring point, and the water guide oil temperature of the water turbine is a measuring point.

[0048] For the main transformer, the corresponding equipment measurement points include the overall health assessment of the main transformer, the number of bushings, the number of cooler systems, the number of main transformer oil data analyses, the number of core clamps, and the equipment condition assessment of the main transformer.

[0049] For the outlet bus, the corresponding equipment measurement points include the overall health status evaluation of the generator outlet bus system, the number of generator outlet switches, the number of electrical brake switches, the number of phase switching switches, the number of starting bus section disconnect switches, and the equipment status evaluation of the generator outlet bus system.

[0050] In an exemplary embodiment, as shown in FIG2, a monitoring and early warning method for power equipment is provided. Taking the application of this method to the power equipment operation monitoring system in FIG1 as an example, the method includes the following steps:

[0051] Step S202: Obtain the operating data of the associated power equipment for each system account at each corresponding device measurement point.

[0052] Each system account is associated with power devices that the system account has data viewing permissions for. In practical applications, each system account has multiple associated power devices under each device type.

[0053] Among them, the power equipment operation monitoring system can read and store the operation data of power equipment in real time.

[0054] Specifically, for each system account, the power equipment operation monitoring system determines the power equipment for which the system account has data viewing permissions based on the system account's permission information within the power equipment operation monitoring system for each equipment type. These power equipment are then designated as the associated power equipment for the system account. The power equipment operation monitoring system then reads the operation data of each associated power equipment for the system account from the internal data table used to store the operation data of the power equipment, at each measurement point of its corresponding equipment type.

[0055] The permission information for each system account describes the scope of data viewing permissions for that system account.

[0056] For example, the power equipment operation monitoring system obtains the operating data of each turbine, each inlet valve, each technical water supply pump, each excitation system, each governor, each SFC, each GCB, each GIS, each main transformer, and each outlet busbar from the power equipment associated with the system account at their respective equipment measurement points.

[0057] Step S204: Based on the operating data of the associated power equipment of each system account at each corresponding device measurement point, determine the measurement point index value of the associated power equipment of each system account at each corresponding device measurement point, and generate a visualization chart of the operating data corresponding to each system account.

[0058] Each device measuring point has at least one corresponding measuring point index, which is used to characterize the distribution of operational data at the device measuring point. In practical applications, the measuring point index consists of the maximum, minimum, and average values ​​of the operational data at the device measuring point within a preset time interval.

[0059] For example, taking the water guide tile temperature of a water turbine as an example, its measuring indicators include "maximum water guide tile temperature", "minimum water guide tile temperature" and "average water guide tile temperature".

[0060] The maximum value refers to the maximum value among the daily averages within a preset time interval, such as the last seven days; the minimum value refers to the minimum value among the daily averages within a preset time interval, such as the last seven days; and the average value refers to the average value within a preset time interval, such as the last seven days.

[0061] Each measurement point indicator has corresponding chart elements in the running data visualization chart, such as marked points, marked areas, or specific values.

[0062] Among them, the operational data visualization charts are used to represent the changes and distribution of operational data.

[0063] Specifically, for each system account, the power equipment operation monitoring system calculates the measurement point index value of each associated power device under the corresponding measurement point based on the operation data of each associated power device under the corresponding measurement point. Based on the operation data and measurement point index value of each associated power device under the corresponding measurement point, the system generates an operation data visualization chart representing the changes and distribution of the operation data of each associated power device under the corresponding measurement point.

[0064] In practical applications, there are multiple operational data visualization charts. Each operational data visualization chart can correspond to an associated power device, an associated device type, or an associated device measurement point.

[0065] In practical applications, since the running data is often time-series data that is highly correlated with time, the generation of running data visualization charts can be either regenerated or updated based on the original running data visualization charts.

[0066] In practical applications, data visualization charts can be line charts, bar charts, or pie charts.

[0067] Step S206: Through the display page of the power equipment operation monitoring system, the corresponding operation data visualization chart is displayed to each system account, so as to realize the monitoring and early warning of the associated power equipment for each system account based on the various chart elements in the operation data visualization chart.

[0068] Specifically, the power equipment operation monitoring system displays the corresponding operation data visualization charts for each system account on the corresponding display page. By logging into the terminal of the system account, the system user is shown the corresponding operation data visualization charts. For each measuring point indicator, if the value of the measuring point indicator is abnormal, the system will issue an alert to the system account through the corresponding chart element in the operation data visualization chart. This enables the system user to monitor and issue alerts for each associated power equipment of the system account.

[0069] In the above-mentioned power equipment monitoring and early warning methods, the power equipment monitoring and early warning method based on the above process can realize the calculation, analysis and generation of corresponding visualization charts of the operation data through the power equipment operation monitoring system, and can realize monitoring and early warning based on the chart elements in the visualization charts, avoiding the problem of low early warning timeliness caused by manual analysis, and improving the early warning timeliness of power equipment.

[0070] In an exemplary embodiment, as shown in Figure 3, step S204, which involves determining the measurement point index value of the associated power equipment of each system account under the corresponding measurement point based on the operating data of the associated power equipment at each corresponding measurement point, and generating a visualization chart of the operating data corresponding to each system account, specifically includes the following steps:

[0071] Step S302: For each system account, based on the operating data of the associated power equipment at each corresponding device measurement point, determine the measurement point index value of the associated power equipment at each device measurement point.

[0072] Step S304: Based on the measurement point index values ​​of the associated power equipment under each measurement point index, determine the color corresponding to each measurement point index.

[0073] Step S306: Based on the operating data of the associated power equipment at each equipment measuring point, the measuring point index values ​​of the associated power equipment at each equipment measuring point, and the color corresponding to each measuring point index, generate an operating data visualization chart corresponding to the system account.

[0074] In the data visualization chart, the color of the chart element corresponding to each measurement point indicator is the same as the color of the measurement point indicator.

[0075] Specifically, for each system account, the power equipment operation monitoring system calculates the specific values ​​of each device measurement point of each associated power device under that system account, based on the operational data under that device measurement point, for the maximum, minimum, and average values ​​of the corresponding measurement point index. Then, for each measurement point index, the power equipment operation monitoring system determines the color corresponding to that measurement point index from a preset range of colors based on the specific value of that measurement point index. Next, the power equipment operation monitoring system determines the color corresponding to each measurement point index of each device measurement point of each associated power device under that system account as the color of the chart element corresponding to that measurement point index, and generates an operational data visualization chart corresponding to the system account based on the operational data of each associated power device under each corresponding device measurement point (data corresponding to each time point), the specific values ​​of each associated power device under each corresponding device measurement point index of each device measurement point, and the color of the chart element corresponding to each measurement point index.

[0076] For example, taking the associated power equipment as turbines 1, 2, and 3, and the corresponding equipment measuring point as the water guide tile temperature, the power equipment operation monitoring system determines the measuring point index values ​​of each turbine under three measuring point indicators: "maximum water guide tile temperature," "minimum water guide tile temperature," and "average water guide tile temperature," based on the operating data of each turbine under the water guide tile temperature. This yields the maximum, minimum, and average water guide tile temperature of each turbine over seven days. Furthermore, based on the turbine... 1. Based on the maximum water guide tile temperature of each of the three turbines (1, 2, and 3), the color corresponding to the "maximum water guide tile temperature" measurement point index for each turbine is determined to be green. Based on the minimum water guide tile temperature of each of the three turbines (1, 2, and 3), the color corresponding to the "minimum water guide tile temperature" measurement point index for each turbine is determined to be red. Based on the average water guide tile temperature of each of the three turbines (1, 2, and 3), the color corresponding to the "average water guide tile temperature" measurement point index for each turbine is determined to be orange. Then, the power equipment operation monitoring system generates operation data visualization charts representing the changes in water guide tile temperature of turbine 1, turbine 2, and turbine 3 at various times, based on the water guide tile temperature operation data of each turbine 1, turbine 2, and turbine 3, the maximum, minimum, and average water guide tile temperatures of each turbine 1, turbine 2, and turbine 3, and the colors corresponding to the measurement point indicators "maximum water guide tile temperature" (green), "minimum water guide tile temperature" (red), and "average water guide tile temperature" (orange) of each turbine 1, turbine 2, and turbine 3, respectively.

[0077] In this embodiment, the power equipment operation monitoring system determines the color of the chart element in the operation data visualization chart for each measurement point index based on the measurement point index value of the associated power equipment under each measurement point index, thereby enabling the monitoring and early warning of the associated power equipment based on the operation data visualization chart.

[0078] In one exemplary embodiment, each measurement point index has multiple corresponding numerical ranges.

[0079] Each measurement point indicator has a mapping relationship with each numerical range and multiple preset risk levels, with each numerical range corresponding to a risk level.

[0080] There is a mapping relationship between the preset risk levels and the preset colors, with each risk level corresponding to a color.

[0081] In practical applications, the number of numerical intervals corresponding to each measuring point indicator is the same; and the number of numerical intervals, the number of risk levels, and the number of colors are also the same.

[0082] In practical applications, there are four numerical ranges, four risk levels, and four colors. The preset risk levels are normal, warning, abnormal, and severe. The preset colors are green, yellow, orange, and red. The color corresponding to normal is green, the color corresponding to warning is yellow, the color corresponding to abnormal is orange, and the color corresponding to severe is red.

[0083] As shown in Figure 4, step S304 above, based on the measurement index values ​​of the associated power equipment under each corresponding measurement point index, determines the color corresponding to each measurement point index, specifically including the following steps:

[0084] Step S402: For each measuring point indicator, determine the target value range into which the measuring point indicator value falls within the multiple value ranges corresponding to the measuring point indicator.

[0085] Step S404: Among the preset multiple risk levels, determine the target risk level corresponding to the target value range.

[0086] Step S406: Determine the color corresponding to the target risk level as the color corresponding to the measuring point indicator.

[0087] Each risk level corresponds to a different color.

[0088] Specifically, for each measuring point indicator, the power equipment operation monitoring system determines the numerical range into which the measuring point indicator value falls within the multiple numerical ranges corresponding to that measuring point indicator, and designates this range as the target numerical range. Then, based on the mapping relationship between risk level and numerical range, the power equipment operation monitoring system determines the risk level corresponding to the target numerical range from the four preset risk levels of normal, caution, abnormal, and severe, and designates this as the target risk level. Finally, based on the mapping relationship between risk level and color, the power equipment operation monitoring system determines the color corresponding to the target risk level from the four preset colors of green, yellow, orange, and red, and designates this color as the color corresponding to that measuring point indicator.

[0089] For example, when the maximum water guide tile temperature of turbine 1 falls within the target value range corresponding to the target risk level of "normal", the power equipment operation monitoring system will determine the color corresponding to the measuring point indicator "maximum water guide tile temperature" as green, which corresponds to "normal"; when the minimum water guide tile temperature of turbine 1 falls within the target value range corresponding to the target risk level of "severe", the power equipment operation monitoring system will determine the color corresponding to the measuring point indicator "minimum water guide tile temperature" as red, which corresponds to "abnormal"; when the average water guide tile temperature of turbine 1 falls within the target value range corresponding to the target risk level of "abnormal", the power equipment operation monitoring system will determine the color corresponding to the measuring point indicator "average water guide tile temperature" as orange, which corresponds to "abnormal".

[0090] In this embodiment, the power equipment operation monitoring system configures different colors for the chart elements corresponding to the measurement point indicators in the operation data visualization chart based on the measurement point indicator values. This allows users to quickly and intuitively determine whether the measurement point indicator values ​​are abnormal based on the colors of the chart elements, and thus realizes the monitoring and early warning of related power equipment based on the operation data visualization chart.

[0091] In an exemplary embodiment, the power equipment monitoring and early warning method provided in this application further includes the following: when a configuration modification request is received from any system account through the configuration page of the power equipment operation monitoring system, the configuration information of the power equipment operation monitoring system is modified in response to the configuration modification request.

[0092] The configuration information includes the equipment measurement points corresponding to each equipment type, the power equipment under each equipment type, the measurement point index corresponding to each equipment measurement point, the numerical range corresponding to each measurement point index, multiple preset risk levels, the mapping relationship between the numerical range corresponding to each measurement point index and the multiple preset risk levels, and at least one of the associated power equipment for each system account.

[0093] Specifically, the power equipment operation monitoring system also features a custom configuration function. System users can access the configuration page of the power equipment operation monitoring system through their logged-in system accounts. They can customize and modify configuration information such as the equipment measurement points for each equipment type, the power equipment under each equipment type, the measurement indicators for each equipment measurement point, the numerical ranges for each measurement indicator, multiple preset risk levels, the mapping relationship between the numerical ranges for each measurement indicator and the multiple preset risk levels, and the associated power equipment for each system account. Modifications include adding, deleting, and updating. Therefore, when the power equipment operation monitoring system receives a configuration modification request from any system account through the configuration page, the power equipment operation monitoring system responds to the configuration modification request and modifies the configuration information of the power equipment operation monitoring system.

[0094] In practical applications, the configuration information also includes multiple preset colors and the mapping relationship between multiple preset risk levels and multiple preset colors; system users can customize and modify the multiple preset colors and the mapping relationship between multiple preset risk levels and multiple preset colors through the configuration page.

[0095] In this embodiment, the power equipment operation monitoring system supports system users to flexibly customize configuration information.

[0096] In an exemplary embodiment, the power equipment monitoring and early warning method provided in this application further includes the following: based on the permission information of each system account under the power equipment operation monitoring system, determining at least one associated power plant in multiple power plants for which each system account has data viewing permissions; and determining each power device under the associated power plant of each system account as the associated power device of each system account.

[0097] Among them, each power equipment under multiple equipment categories refers to the power equipment of multiple power plants under multiple equipment categories; each power plant has multiple power equipment under each equipment category.

[0098] Among them, the system accounts under the power equipment operation monitoring system can be divided into system accounts corresponding to a single power plant and system accounts corresponding to multiple power plants according to the scope of their corresponding data viewing permissions; the system account corresponding to a single power plant is associated with one power plant, and the system account corresponding to multiple power plants is associated with multiple power plants.

[0099] Specifically, for each system account, the power equipment operation monitoring system determines at least one power plant among multiple power plants that the system account has data viewing permissions based on the system account's permission information under the power equipment operation monitoring system. This power plant is then designated as the associated power plant corresponding to the system account. Finally, each power device under each associated power plant of the system account is designated as the associated power device of the system account.

[0100] For example, taking multiple power plants as Plant A, Plant B, Plant C, and Plant D, assuming that system account 1 only has data viewing permissions for Plant A, then the associated power plant of system account 1 is Plant A, and the associated power equipment of system account 1 includes each turbine, each inlet valve, each technical water supply pump, each excitation system, each governor, each SFC, each GCB, each GIS, each main transformer, and each outlet bus of Plant A.

[0101] Assuming that system account 2 only has data viewing permissions for plants A and B, then the associated power plants of system account 2 are plants A and B, and the associated power equipment of system account 2 are each turbine, each inlet valve, each technical water supply pump, each excitation system, each governor, each SFC, each GCB, each GIS, each main transformer, and each outlet bus of plants A and B.

[0102] Assuming that system account 3 has data viewing permissions for plants A, B, C, and D, then the associated power plants of system account 3 are plants A, B, C, and D. The associated power equipment of system account 3 includes each turbine, each inlet valve, each technical water supply pump, each excitation system, each governor, each SFC, each GCB, each GIS, each main transformer, and each outlet busbar of plants A, B, C, and D.

[0103] In this embodiment, the power equipment operation monitoring system can determine the associated power plant of the system account through the system account's permission information, and thus determine the associated power equipment of the system account.

[0104] In one exemplary embodiment, each system account corresponds to multiple runtime data visualization charts, and the display page contains selection controls for each runtime data visualization chart.

[0105] The power equipment monitoring and early warning method provided in this application also includes the following: for each system account, in response to the system account's selection operation on any selection control on the display page, the operation data visualization chart corresponding to the selected selection control is determined as the operation data visualization chart to be displayed; based on the display page, the operation data visualization chart to be displayed is displayed to the system account.

[0106] Specifically, for each system account, the power equipment operation monitoring system responds to the system account's selection operation on any selection control on the display page, determines the operation data visualization chart corresponding to the selected selection control as the operation data visualization chart to be displayed, and displays the operation data visualization chart to be displayed to the system account based on the display page.

[0107] In this embodiment, the power equipment operation monitoring system displays various operation data visualization charts according to different levels, which increases the organization and logic of the operation data visualization charts, and thus increases the organization and logic of monitoring and early warning.

[0108] In an exemplary embodiment, as shown in Figure 5, step S306 above, which generates an operational data visualization chart corresponding to the system account based on the operational data of the associated power equipment at each equipment measuring point, the measuring point index values ​​of the associated power equipment at each equipment measuring point, and the color corresponding to each measuring point index, specifically includes the following steps:

[0109] Step S502: For each associated power plant, based on the operating data of the associated power equipment under the associated power plant at each equipment measurement point, the measurement point index value of the associated power equipment under the associated power plant at each equipment measurement point, and the color corresponding to each measurement point index, generate a first operating data visualization chart and a second operating data visualization chart for the associated power plant.

[0110] Step S504: The first and second operation data visualization charts of each associated power plant of the system account are determined as the operation data visualization charts corresponding to the system account.

[0111] Each associated power plant has multiple first-operation data visualization charts. Each first-operation data visualization chart represents the change in operating data of an associated power device under the associated power plant at a specific measuring point (of its equipment type). For example, if the associated power plant of the system account is Plant A, a certain first-operation data visualization chart for Plant A represents the change in water guide plate temperature data of turbine 1 under Plant A at a corresponding water guide plate temperature, and a certain first-operation data visualization chart for Plant A represents the change in water guide plate temperature data of turbine 2 under Plant A at a different water guide plate temperature.

[0112] Each associated power plant has multiple second-stage operational data visualization charts. Each chart represents the distribution of operational data for each associated power device within a specific equipment category at a given measurement point within that category. For example, if the associated power plant for a system account is Plant A, a second-stage operational data visualization chart for Plant A represents the distribution of water guide bearing temperature data for all turbines under Plant A at a given water guide bearing temperature, and another chart for Plant A represents the distribution of water guide oil temperature data for all turbines under Plant A at a given water guide oil temperature.

[0113] Specifically, for each system account, regardless of whether the number of associated power plants is one or more, the corresponding operation data visualization charts for each system account include multiple first operation data visualization charts and multiple second operation data visualization charts for each associated power plant of the system account.

[0114] For each associated power plant, each first operational data visualization chart corresponds to an associated power device under that power plant and a corresponding equipment measuring point of that associated power device, used to characterize the changes in the operational data of that associated power device at that corresponding equipment measuring point. Therefore, for each associated power device in the associated power plant, the power equipment operation monitoring system generates a first operational data visualization chart corresponding to that associated power device and each equipment measuring point, based on the operational data of that associated power device at each equipment measuring point (of its equipment type), the measuring point index value of that associated power device at each measuring point index of each corresponding measuring point, and the color corresponding to each measuring point index.

[0115] For each associated power plant, each second operational data visualization chart corresponds to all associated power equipment under a certain equipment type and a corresponding equipment measurement point for that equipment type. This chart characterizes the distribution of operational data for each associated power equipment under that equipment type at that corresponding equipment measurement point. Therefore, for each equipment type of the associated power plant, the power equipment operation monitoring system generates a second operational data visualization chart corresponding to that equipment type and each equipment measurement point, based on the operational data of all associated power equipment under that equipment type at each equipment measurement point, the measurement point index values ​​of all associated power equipment under that equipment type at each measurement point index, and the color corresponding to each measurement point index.

[0116] Then, the power equipment operation monitoring system identifies the first and second operation data visualization charts of each associated power plant of the system account as the operation data visualization charts corresponding to the system account.

[0117] In this embodiment, the power equipment operation monitoring system generates a first operation data visualization chart corresponding to an associated power equipment and a device measuring point, and generates a second operation data visualization chart corresponding to each associated power equipment and a device measuring point under a device type. This allows for an intuitive display of the power equipment operation data at different granularities (single power equipment or single device type).

[0118] In an exemplary embodiment, as shown in Figure 6, step S206 above, which displays corresponding operational data visualization charts to each system account through the display page of the power equipment operation monitoring system, specifically includes the following steps:

[0119] Step S602: For each system account, if the system account is associated with only one power plant, in response to the system account's selection operation on any device type selection control on the display page, the device type corresponding to the selected device type selection control is determined as the target device type.

[0120] Step S604: Based on the display page, display the second operation data visualization chart corresponding to the target equipment type in the second operation data visualization chart of the associated power plant to the system account, and the power equipment selection control corresponding to each associated power equipment of the associated power plant under the target equipment type.

[0121] Step S606: In response to the system account's selection operation on any power device selection control on the display page, the associated power device corresponding to the selected power device selection control is determined as the target associated power device.

[0122] Step S608: Based on the display page, display the first operation data visualization chart corresponding to the target associated power equipment in the first operation data visualization chart of the associated power plant to the system account.

[0123] The display page includes device type selection controls for each device type.

[0124] Specifically, regardless of whether a system account is associated with one or more power plants, the display page of the power equipment operation monitoring system includes equipment type selection controls for each equipment type. For each system account, if the system account is associated with only one power plant (i.e., the system account corresponds to a single power plant), the system user, based on their logged-in system account, can select the desired equipment type from the various equipment type selection controls on the display page. In response to this system account's selection of any equipment type selection control, the power equipment operation monitoring system identifies the selected equipment type as the target equipment type. Based on the display page, it presents the system account with the second operational data visualization chart corresponding to the target equipment type from the various second operational data visualization charts of its associated power plants. This second operational data visualization chart represents the operational data of each associated power device of the associated power plant under the target equipment type at each equipment measurement point corresponding to the target equipment type, and also displays the equipment selection controls corresponding to each associated power device of the associated power plant under the target equipment type.

[0125] For example, referring to Figure 7, the display page defaults to the main page, which has equipment type selection controls on the left side. Assuming the power plant associated with the system account is Plant A, when the system account selects the equipment type selection control for "hydro turbine," the display page enters the subpage corresponding to the hydro turbines of Plant A. This subpage displays a visualization chart of the second operating data of each hydro turbine of Plant A under the corresponding equipment measurement points, as well as the power equipment selection controls for each hydro turbine of Plant A.

[0126] Then, based on their logged-in system account, system users can select the power equipment selection control corresponding to the associated power equipment they want to view from the various power equipment selection controls on the display page. In response to the system account's selection operation of any power equipment selection control, the power equipment operation monitoring system identifies the associated power equipment corresponding to the selected power equipment selection control as the target associated power equipment. Based on the display page, the system account is shown the first operation data visualization chart corresponding to the target associated power equipment in the various first operation data visualization charts of its associated power plant. That is, the first operation data visualization chart representing the operation data of the target associated power equipment under the associated power plant at various equipment measurement points corresponding to the target equipment type.

[0127] For example, referring to Figure 8, when the system account selects the power equipment selection control corresponding to "hydro turbine 1", the display page enters the subpage corresponding to hydro turbine 1 of Plant A. In this subpage, a visualization chart of the first operating data of hydro turbine 1 of Plant A under each equipment measurement point corresponding to the hydro turbine is displayed.

[0128] It is easy to understand that Figures 7 and 8 are only used to illustrate this embodiment and are not intended to limit the types of equipment, equipment measurement points and display pages in this application.

[0129] In this embodiment, the power equipment operation monitoring system can display operation data visualization charts in an organized, orderly, and hierarchical manner by displaying various selection controls on the display page, thereby increasing the organization and logic of the power equipment operation data visualization.

[0130] In an exemplary embodiment, after generating the first and second operational data visualization charts of the associated power plant in step S502, based on the operational data of the associated power equipment under the associated power plant at each equipment measurement point, the measurement point index values ​​of the associated power equipment under the associated power plant at each equipment measurement point, and the color corresponding to each measurement point index, the following additional steps are included: when there are multiple associated power plants in the system account, for each equipment type, based on the operational data of each associated power equipment under the equipment type of all associated power plants at each equipment measurement point, the measurement point index values ​​of each associated power equipment under the equipment type of all associated power plants at each equipment measurement point, and the color corresponding to each measurement point index, a third operational data visualization chart of the system account is generated.

[0131] The system account has multiple third-level operational data visualization charts. Each chart represents the distribution of operational data for all associated power plants under a specific equipment category at a given measurement point within that category. For example, if the system account has associated power plants A and B, a third-level operational data visualization chart might represent the distribution of water guide bearing temperature data for all turbines under plants A and B at a given water guide bearing temperature, and another chart might represent the distribution of water guide oil temperature data for all turbines under plants A and B at a given water guide oil temperature.

[0132] Specifically, for each system account, when the number of associated power plants of the system account is multiple, the operation data visualization charts corresponding to the system account include multiple first operation data visualization charts and multiple second operation data visualization charts, as well as multiple third operation data visualization charts.

[0133] For each system account, each third operational data visualization chart corresponds to all associated power equipment under a specific equipment type for all associated power plants of that system account and one equipment measurement point corresponding to that equipment type. This chart represents the distribution of operational data for each associated power device under that specific equipment type at that corresponding equipment measurement point for all associated power plants of that system account. Therefore, the power equipment operation monitoring system generates a third operational data visualization chart corresponding to that equipment type and each equipment measurement point for that system account, based on the operational data of all associated power equipment under that equipment type at each equipment measurement point, the measurement point indicator values ​​of all associated power equipment under that equipment type at each measurement point indicator, and the color corresponding to each measurement point indicator.

[0134] Step S504 above, which determines the first and second operation data visualization charts of each associated power plant of the system account as the operation data visualization charts corresponding to the system account, specifically includes the following: when there are multiple associated power plants, the third operation data visualization chart of the system account, the first and second operation data visualization charts of each associated power plant of the system account are determined as the operation data visualization charts corresponding to the system account.

[0135] Then, the power equipment operation monitoring system identifies the first operation data visualization chart, the second operation data visualization chart, and the third operation data visualization chart of each associated power plant of the system account as the operation data visualization chart corresponding to the system account.

[0136] In this embodiment, the power equipment operation monitoring system generates a first operation data visualization chart corresponding to an associated power equipment and a device measuring point, a second operation data visualization chart corresponding to each power equipment and a device measuring point under a device type, and a third operation data visualization chart corresponding to each associated power equipment and a device measuring point under a device type. This allows the system to intuitively display the operation data of power equipment at different granularities (single power equipment or single device type).

[0137] In an exemplary embodiment, as shown in Figure 9, step S206 above, which displays corresponding operational data visualization charts to each system account through the display page of the power equipment operation monitoring system, specifically includes the following steps:

[0138] Step S902: For each system account, if there are multiple associated power plants, in response to the system account's selection operation on any device type selection control on the display page, the device type corresponding to the selected device type selection control is determined as the target device type.

[0139] Step S904: Based on the display page, display the third operational data visualization chart corresponding to the target equipment type in the third operational data visualization chart of the system account, and the power plant selection control corresponding to each associated power plant of the system account to the system account.

[0140] Step S906: In response to the system account's selection operation of any power plant selection control on the display page, the associated power plant corresponding to the selected power plant selection control is determined as the target associated power plant.

[0141] Step S908: Based on the display page, display the second operation data visualization chart corresponding to the target equipment type in the second operation data visualization chart of the target associated power plant to the system account, and the power equipment selection control corresponding to each associated power equipment of the target associated power plant under the target equipment type.

[0142] Step S910: In response to the system account's selection operation on any power device selection control on the display page, the associated power device corresponding to the selected power device selection control is determined as the target associated power device.

[0143] Step S912: Based on the display page, display the first operation data visualization chart corresponding to the target associated power equipment in the first operation data visualization chart of the target associated power plant to the system account.

[0144] The display page includes device type selection controls for each device type.

[0145] Specifically, regardless of whether a system account is associated with one or more power plants, the display page of the power equipment operation monitoring system includes equipment type selection controls for each equipment type. For each system account, if the system account is associated with multiple power plants (i.e., the system account corresponds to multiple power plants), the system user, based on their logged-in system account, can select the desired equipment type from the various equipment type selection controls on the display page. In response to this system account's selection of any equipment type selection control, the power equipment operation monitoring system identifies the selected equipment type as the target equipment type. Based on the display page, it presents the system account with the third-level operational data visualization chart corresponding to the target equipment type from its various third-level operational data visualization charts. This chart represents the operational data of all power equipment under the target equipment type from all associated power plants of the system account at each equipment measurement point corresponding to that target equipment type, as well as the power plant selection controls corresponding to each associated power plant of the system account.

[0146] For example, referring to Figure 10, the display page defaults to the main page, with equipment type selection controls on the left side for each equipment type. Assuming the system account is associated with power plants A, B, C, and D, when the system account selects the equipment type selection control for "hydro turbine," the display page navigates to a subpage corresponding to the hydro turbines of all associated power plants. This subpage displays visualization charts of the third-level operating data for each hydro turbine in plants A, B, C, and D at each corresponding equipment measurement point, along with power plant selection controls for plants A, B, C, and D.

[0147] Then, based on their logged-in system account, system users can select the power plant selection control corresponding to the associated power plant they want to view from the various power plant selection controls on the display page. The power equipment operation monitoring system responds to the system account's selection operation on any power plant selection control, identifies the associated power plant corresponding to the selected power plant selection control as the target associated power plant, and displays the second operation data visualization chart corresponding to the target equipment type in the various second operation data visualization charts of the target associated power plant to the system account based on the display page. That is, the second operation data visualization chart representing the operation data of each associated power equipment of the target associated power plant under the target equipment type at each equipment measurement point corresponding to the target equipment type, and displays the power equipment selection control corresponding to each associated power equipment of the target associated power plant under the target equipment type.

[0148] For example, referring to Figure 11, when the system account selects the power plant selection control corresponding to "Plant A", the display page enters the subpage corresponding to the turbines of Plant A. On this subpage, there are second operation data visualization charts of each turbine of Plant A under the corresponding equipment measurement points of each turbine, as well as power equipment selection controls for each turbine of Plant A.

[0149] Then, based on their logged-in system account, system users can select the power equipment selection control corresponding to the associated power equipment they want to view from the various power equipment selection controls on the display page. In response to the system account's selection operation of any power equipment selection control, the power equipment operation monitoring system identifies the associated power equipment corresponding to the selected power equipment selection control as the target associated power equipment. Based on the display page, the system account is shown the first operation data visualization chart corresponding to the target associated power equipment in the various first operation data visualization charts of the target associated power plant. That is, the first operation data visualization chart represents the operation data of the target associated power equipment under the target associated power plant at various equipment measurement points corresponding to the target equipment type.

[0150] For example, referring to Figure 12, when the system account selects the power equipment selection control corresponding to "Water Turbine 1", the display page enters the subpage corresponding to Water Turbine 1 of Plant A. In this subpage, a visualization chart of the first operating data of Water Turbine 1 of Plant A under each equipment measurement point corresponding to the water turbine is displayed.

[0151] It is easy to understand that Figures 10, 11 and 12 are only used to illustrate this embodiment and are not intended to limit the types of equipment, equipment measurement points and display pages in this application.

[0152] In this embodiment, the power equipment operation monitoring system can display operation data visualization charts in an organized, orderly, and hierarchical manner by displaying various selection controls on the display page, thereby increasing the organization and logic of the power equipment operation data visualization.

[0153] In an exemplary embodiment, as shown in Figure 13, step S204 above, which generates an operational data visualization chart corresponding to the system account based on the operational data of the associated power equipment at each device measuring point, the measuring point index values ​​of the associated power equipment at each device measuring point, and the color corresponding to each measuring point index, specifically includes the following steps:

[0154] Step S1302: For each system account, determine the number of associated power plants for that system account.

[0155] When the number of associated power plants is one, perform the following steps S1304 to S1306:

[0156] S1304. Based on the operating data of the associated power equipment under the associated power plant at each equipment measuring point, the measuring point index value of the associated power equipment under the associated power plant at each equipment measuring point, and the color corresponding to each measuring point index, generate the first operating data visualization chart and the second operating data visualization chart of the associated power plant.

[0157] S1306, the first and second operation data visualization charts of the associated power plant are identified as the operation data visualization charts corresponding to the system account.

[0158] When there are multiple associated power plants, perform the following steps S1308 to S1312:

[0159] S1308, for each associated power plant, based on the operating data of the associated power equipment under the associated power plant at each equipment measuring point, the measuring point index value of the associated power equipment under the associated power plant at each equipment measuring point, and the color corresponding to each measuring point index, generate a first operating data visualization chart and a second operating data visualization chart for the associated power plant.

[0160] S1310, for each equipment type, generates a third operational data visualization chart for the system account based on the operational data of each associated power equipment of all associated power plants under each equipment type at each equipment measurement point, the measurement point index values ​​of each associated power equipment of all associated power plants under each equipment type at each equipment measurement point, and the color corresponding to each measurement point index.

[0161] S1312, the third operational data visualization chart of the system account, the first operational data visualization chart and the second operational data visualization chart of each associated power plant of the system account are determined as the operational data visualization chart corresponding to the system account.

[0162] In an exemplary embodiment, when the mouse of the system account moves to a chart element in the running data visualization chart, the running data visualization chart pops up a floating window to display the information corresponding to the chart element, such as the power plant, power equipment, and specific values.

[0163] In an exemplary embodiment, the configuration information may also include at least one of the following: the type of equipment corresponding to the power equipment operation monitoring system, the power plant corresponding to the power equipment operation monitoring system, the power equipment under each power plant, and the associated power plant of each system account.

[0164] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the above embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0165] To more clearly illustrate the monitoring and early warning method for power equipment provided in the embodiments of this application, a specific embodiment is described below. However, it should be understood that the embodiments of this application are not limited thereto. In one exemplary embodiment, this application also provides an operation monitoring system for power equipment, which specifically includes the following functions:

[0166] Function 1: Displays power equipment measurement data at the company and plant / station levels, allowing users to view the operational status of the power equipment.

[0167] Feature 2: Supports visualization of measurement point data through a variety of chart types, such as line charts, bar charts, and pie charts.

[0168] Function 3: Monitoring and alerts are implemented through chart elements. Each data point corresponds to a chart element, and the color of each chart element is determined according to the risk level of the data (normal, warning, abnormal, severe). The color of the chart element can intuitively represent the alert.

[0169] Function 4: Supports data visualization for multiple types of power equipment, including generators, turbines, inlet valves, technical water supply pumps, excitation systems, speed governors, SFC, GCB, GIS, main transformers, and outlet busbars.

[0170] Function 5: Hierarchical Data Display on Display Pages; The display pages are divided into three categories: All Pages, Plant Pages, and Unit Pages, allowing users to switch between different levels of pages by clicking tabs. The All Page, as shown in Figure 10, displays the measurement data of all power equipment under a specific equipment type at all measurement points in all plants. The Plant Pages, as shown in Figures 7 and 11, display the measurement data of all power equipment under a specific equipment type at a specific plant at all measurement points. The Unit Pages, as shown in Figures 8 and 12, display the measurement data of a specific power equipment under a specific equipment type at a specific plant at all measurement points.

[0171] Function 5: Supports user-defined settings for various information, including equipment type, power equipment under the equipment type, measuring points corresponding to the equipment type, data calculation method for measuring points, chart type, risk level, and color of risk level.

[0172] Based on the same inventive concept, this application also provides a power equipment operation monitoring system for implementing the aforementioned power equipment monitoring and early warning method. The solution provided by this device is similar to the implementation scheme described in the above method; therefore, the specific limitations of one or more power equipment operation monitoring system embodiments provided below can be found in the limitations of the power equipment monitoring and early warning method described above, and will not be repeated here.

[0173] The power equipment operation monitoring system is used to monitor and provide early warnings for various power equipment under multiple equipment categories. There are multiple power equipment under each equipment category, and each equipment category has multiple corresponding equipment measuring points. There are multiple system accounts under the power equipment operation monitoring system.

[0178] In an exemplary embodiment, the chart generation module 1404 is further configured to, for each system account, determine the measurement point index value of the associated power equipment under the measurement point index of each device measurement point based on the operating data of the associated power equipment under each device measurement point of the system account; determine the color corresponding to each measurement point index based on the measurement point index value of the associated power equipment under each measurement point index; generate an operating data visualization chart corresponding to the system account based on the operating data of the associated power equipment under each device measurement point, the measurement point index value of the associated power equipment under each device measurement point index, and the color corresponding to each measurement point index; in the operating data visualization chart, the color of the chart element corresponding to each measurement point index is the color corresponding to the measurement point index.

[0179] In one exemplary embodiment, each measurement point index has multiple corresponding numerical ranges.

[0180] The chart generation module 1404 is also used to determine the target value range in which the value of the measuring point indicator falls within the multiple value ranges corresponding to the measuring point indicator for each measuring point indicator; determine the target risk level corresponding to the target value range among the multiple preset risk levels; each risk level corresponds to a different color; and determine the color corresponding to the target risk level as the color corresponding to the measuring point indicator.

[0181] In one exemplary embodiment, the power equipment operation monitoring system further includes a custom configuration module, which, upon receiving a configuration modification request from any system account via the configuration page of the power equipment operation monitoring system, modifies the configuration information of the power equipment operation monitoring system in response to the configuration modification request. The configuration information includes equipment measurement points corresponding to each equipment type, power equipment under each equipment type, measurement point indicators corresponding to each equipment measurement point, numerical ranges corresponding to each measurement point indicator, multiple preset risk levels, the mapping relationship between the numerical ranges corresponding to each measurement point indicator and the multiple preset risk levels, and at least one of the associated power equipment of each system account.

[0183] In one exemplary embodiment, each system account corresponds to multiple runtime data visualization charts, and the display page contains selection controls for each runtime data visualization chart.

[0184] The chart display module 1406 is also used to, for each system account, in response to the system account's selection operation on any selection control on the display page, determine the running data visualization chart corresponding to the selected selection control as the running data visualization chart to be displayed; and display the running data visualization chart to be displayed to the system account based on the display page.
