[0051] Specifically, first, the power equipment operation monitoring system 102 determines multiple types of power equipment to be evaluated for operating status; then, the power equipment operation monitoring system 102 determines the operating conditions of the power equipment of each type of equipment, and at least one equipment component that constitutes the power equipment of each type of equipment; next, the power equipment operation monitoring system 102 obtains the historical operating data of each equipment component of the power equipment of each type of equipment under the corresponding operating conditions, and the historical operating status of the power equipment of each type of equipment under the corresponding operating conditions; the historical operating data is the operating data within a historical time interval, and the historical operating status is the operating status within a historical time interval; finally, the power equipment operation monitoring system 102 determines the evaluation index for evaluating the operating status of the power equipment of each type of equipment based on the historical operating data and historical operating status corresponding to the power equipment of each type of equipment.

[0052] After obtaining the evaluation indicators for evaluating the operating status of each type of power equipment, the power equipment operation monitoring system 102 evaluates the operating status of each type of power equipment based on the corresponding evaluation indicators, obtains the operating status evaluation results of each type of power equipment, and displays the operating status evaluation results to each system account through the display page of the power equipment operation monitoring system and the terminal 104 logged in to each system account, so as to realize the visualization of the operating status evaluation results.

[0053] In an exemplary embodiment, Figure 2 As shown, a method for determining the evaluation index of the operating status of power equipment is provided, and the method is applied to Figure 1 The power equipment operation monitoring system in the example is used to illustrate, including the following steps:

[0054] Step S202: determining multiple types of power equipment for which operation status evaluation is to be performed.

[0055] There are multiple electrical equipment under each equipment type.

[0056] Specifically, the power equipment operation monitoring system determines power equipment of each equipment type for which operation status evaluation is to be performed.

[0057] Step S204: determining the operating conditions of the power equipment of each equipment type and at least one equipment component constituting the power equipment of each equipment type.

[0058] The operating conditions are used to describe the specific functions of the power equipment of this type of equipment, for example, whether it undertakes the task of pumping water or the task of generating electricity in the power system.

[0059] Specifically, for each type of power equipment, the power equipment operation monitoring system determines the specific function of the power equipment of this type of equipment in the power system, thereby determining the operating conditions of the power equipment of this type of equipment, and simultaneously analyzes the composition structure of the power equipment of this type of equipment, and splits the power equipment of this type of equipment into at least one equipment component.

[0060] Step S206, acquiring the historical operation data of each device component of the power equipment of each device type under the corresponding operation conditions, and the historical operation status of the power equipment of each device type under the corresponding operation conditions.

[0061] The historical operation data refers to the operation data within the historical time interval, and the historical operation status refers to the operation status within the historical time interval.

[0062] Among them, the power equipment operation monitoring system can read and store the operation data of the power equipment in real time, and evaluate and store the operation status of the power equipment based on the operation data of the power equipment.

[0063] Specifically, for each type of power equipment, the power equipment operation monitoring system reads the historical operation data of the power equipment of this type within the historical time interval from the data table internally used to store the operation data of the power equipment, and reads the historical operation status of the power equipment of this type within the historical time interval from the data table internally used to store the operation status of the power equipment.

[0064] Step S208 : determining an evaluation index for evaluating the operating status of the power equipment of each equipment type based on the historical operating data and historical operating status corresponding to the power equipment of each equipment type.

[0065] Specifically, for each type of power equipment, the power equipment operation monitoring system analyzes the historical operation data of each device component of the power equipment of this type of equipment in the historical time interval, and the historical operation status of the power equipment of this type of equipment in the historical time interval, and determines the relationship between the historical operation data and the historical operation status of each device component, such as the change or distribution of the historical operation data when the historical operation status is an abnormal state; then, based on the relationship between the historical operation data and the historical operation status of each device component, the power equipment operation monitoring system filters out the device components related to the abnormal state from each device component, and determines the data indicators related to the abnormal state for the device components related to the abnormal state; finally, the power equipment operation monitoring system determines the various data indicators related to the abnormal state as evaluation indicators for evaluating the operation status of the power equipment of this type of equipment.

[0066] In the above-mentioned method for determining the evaluation index of the operating status of power equipment, for each type of power equipment, the power equipment operation monitoring system can determine the evaluation index for evaluating the operating status of the power equipment of this type of equipment based on the historical operating status of the power equipment of this type of equipment under the corresponding operating conditions and in the historical time interval, as well as the historical operating data of each equipment component corresponding to the power equipment of this type of equipment in the historical time interval; the method for determining the evaluation index of the operating status of power equipment based on the above-mentioned process no longer relies on the knowledge and experience of experts to determine the evaluation index; therefore, the determined evaluation index is not easily affected by subjective factors, thereby improving the reliability of the evaluation results of the operating status of the power equipment.

[0067] In an exemplary embodiment, Figure 3 As shown, the above step S208, based on the historical operation data and historical operation status corresponding to the power equipment of each equipment type, determines the evaluation index for evaluating the operation status of the power equipment of each equipment type, specifically including the following steps:

[0068] Step S302, for each type of electrical equipment, the time period in the historical time interval corresponding to the electrical equipment of the equipment type during which the corresponding historical operating status is abnormal is determined as an abnormal time period, and the time period in the historical time interval during which the corresponding historical operating status is normal is determined as a normal time period.

[0069] Step S304: determining the first operating data of each device component in an abnormal time period and the second operating data in a normal time period from the historical operating data of each device component of the power equipment of the device type.

[0070] Step S306: for each equipment component, when the difference between the first operating data and the second operating data of the equipment component meets a preset condition, determine at least one evaluation index corresponding to the equipment component.

[0071] Step S308: Determine the evaluation index corresponding to each device component as the evaluation index for evaluating the operating status of the power equipment of the device type.

[0072] There is at least one abnormal time period in the historical time interval, and at least one normal time period in the historical time interval.

[0073] Among them, the first operating data of each equipment component in the abnormal time period is the historical operating data of the equipment component in the abnormal time period; the second operating data of each equipment component in the normal time period is the historical operating data of the equipment component in the normal time period.

[0074] Specifically, for each type of power equipment, the power equipment operation monitoring system divides the historical time interval into at least one abnormal time period and at least one normal time period according to the historical operating status of the power equipment of that type of equipment in the historical time interval, wherein the abnormal time period refers to the time period when the corresponding historical operating status is abnormal, and the normal time period refers to the time period when the corresponding historical operating status is normal.

[0075] Then, the power equipment operation monitoring system divides the operation data of each equipment component of the power equipment of this equipment type into corresponding first operation data and second operation data according to the division of abnormal time periods and normal time periods, wherein the first operation data refers to the historical operation data in the abnormal time period, and the second operation data refers to the historical operation data in the normal time period.

[0076] Next, for each equipment component, the power equipment operation monitoring system compares its first operation data in the abnormal time period (i.e., when the power equipment of this equipment type is in an abnormal state) with its second operation data in the normal time period (i.e., when the power equipment of this equipment type is in a normal state), and determines the difference between the two; if the difference between the two is small, it means that the abnormality of the power equipment of this equipment type is less related to the equipment component, so the equipment component cannot better reflect whether the power equipment of this equipment type is abnormal; if the difference between the two is large, it means that the abnormality of the power equipment of this equipment type is more related to the equipment component, so the equipment component can better reflect whether the power equipment of this equipment type is abnormal, and thus determine at least one evaluation indicator corresponding to the equipment component.

[0077] In a specific application, the power equipment operation monitoring system can distinguish the abnormal states of power equipment of each type according to the abnormal causes, and perform the above step S306 for the abnormal state under each abnormal cause.

[0078] Finally, the power equipment operation monitoring system determines the evaluation index corresponding to each equipment component as the evaluation index used to evaluate the operation status of the power equipment of the equipment type.

[0079] In this embodiment, the power equipment operation monitoring system can determine the relationship between the historical operation data and the historical operation status of each equipment component by analyzing the historical operation data and the corresponding historical operation status of the power equipment of each type of equipment, and then determine the equipment component that can better reflect whether the power equipment is abnormal from the various equipment components, and determine the corresponding evaluation index for the determined equipment component to obtain the evaluation index that can better reflect whether the power equipment is abnormal; the method for determining the evaluation index of the power equipment operation status based on the above process no longer relies on the knowledge and experience of experts to determine the evaluation index. Therefore, the determined evaluation index is not easily affected by subjective factors, thereby improving the reliability of the evaluation results of the power equipment operation status.

[0080] In an exemplary embodiment, the historical operating data of each equipment component includes the historical operating data of the equipment component at at least one corresponding measuring point; for example, for a water turbine, the measuring points of the water guide of its equipment component include water guide bearing temperature, water guide oil temperature and water guide oil level, then the historical operating data of the water guide includes historical water guide bearing temperature, historical water guide oil temperature and historical water guide oil level.

[0081] like Figure 4 As shown, the above step S306, when the difference between the first operating data and the second operating data of the equipment component meets the preset condition, determines at least one evaluation index corresponding to the equipment component, specifically including the following steps:

[0082] Step S402, for each measuring point of the equipment component, determine the first indicator value of the first operating data of the equipment component at the measuring point under each data indicator in the preset multiple data indicators, and determine the second indicator value of the second operating data of the equipment component at the measuring point under each data indicator.

[0083] Step S404: for each data indicator, when the difference between the first indicator value and the second indicator value under the data indicator is greater than or equal to the corresponding preset threshold, determine the data indicator under the measuring point as an evaluation indicator corresponding to the equipment component.

[0084] Among them, each data indicator is used to characterize the distribution of data; in specific applications, the preset multiple data indicators include peak-to-peak value, average value, maximum value and minimum value.

[0085] Each measurement point has a corresponding preset threshold value under each data indicator. For example, the peak-to-peak value of the water-conducting tile temperature corresponds to a preset threshold value, the average value of the water-conducting tile temperature corresponds to a preset threshold value, the maximum value of the water-conducting tile temperature corresponds to a preset threshold value, and the minimum value of the water-conducting tile temperature corresponds to a preset threshold value.

[0086] Specifically, for each measuring point of the equipment component, the power equipment operation monitoring system determines the first operating data of the equipment component at the measuring point (that is, the historical operating data of the equipment component corresponding to the measuring point during the abnormal time period), the first indicator value under each preset data indicator, and determines the second operating data of the equipment component at the measuring point (that is, the historical operating data of the equipment component corresponding to the measuring point during the normal time period), and the second indicator value under each preset data indicator.

[0087] Then, for each data indicator, the power equipment operation monitoring system calculates the difference between the first indicator value and the second indicator value under the data indicator, and compares the difference with the preset threshold value corresponding to the measuring point under the data indicator.

[0088] If the difference is smaller than the corresponding preset threshold, it means that the first indicator value does not deviate from the second indicator value, that is, the first operating data of the equipment component at the measuring point (the historical operating data within the abnormal time period) meets the data characteristics of the operating data of the equipment component at the measuring point under the data indicator. Therefore, it indicates that the abnormality of the electrical equipment of this type of equipment is less correlated with the measuring point of the equipment component, and further indicates that the measuring point of the equipment component cannot well reflect whether the electrical equipment of this type of equipment is abnormal.

[0089] If the difference is greater than or equal to the corresponding preset threshold, it means that the first indicator value deviates from the second indicator value, that is, the first operating data of the equipment component at the measuring point (the historical operating data within the abnormal time period) does not meet the data characteristics of the operating data of the equipment component at the measuring point under the data indicator. Therefore, it means that the abnormality of the power equipment of this type of equipment is closely related to the measuring point of the equipment component, and further indicates that the measuring point of the equipment component can better reflect whether the power equipment of this type of equipment is abnormal. Therefore, the power equipment operation monitoring system determines the data indicator of the equipment component at the measuring point as an evaluation indicator corresponding to the equipment component.

[0090] For example, taking a water turbine as an example, assuming that the measurement points of the water guide of its equipment components include water guide bearing temperature, water guide oil temperature and water guide oil level, the preset multiple data indicators are peak-to-peak value, average value, maximum value and minimum value.

[0091] For the measuring point "water conduction tile temperature", first, the power equipment operation monitoring system calculates the peak-to-peak value of the first water conduction tile temperature, the average value of the first water conduction tile temperature, the maximum value of the first water conduction tile temperature and the minimum value of the first water conduction tile temperature in the abnormal time period, and calculates the peak-to-peak value of the second water conduction tile temperature, the average value of the second water conduction tile temperature, the maximum value of the second water conduction tile temperature and the minimum value of the second water conduction tile temperature in the normal time period.

[0092] Then, the power equipment operation monitoring system calculates the difference between the peak-to-peak value of the first water-conducting bearing temperature and the peak-to-peak value of the second water-conducting bearing temperature, calculates the difference between the average value of the first water-conducting bearing temperature and the average value of the second water-conducting bearing temperature, calculates the difference between the maximum value of the first water-conducting bearing temperature and the maximum value of the second water-conducting bearing temperature, and calculates the difference between the minimum value of the first water-conducting bearing temperature and the minimum value of the second water-conducting bearing temperature.

[0093] If the difference between the first water-conducting tile temperature peak-to-peak value and the second water-conducting tile temperature peak-to-peak value is greater than or equal to the preset threshold corresponding to the water-conducting tile temperature peak-to-peak value, the power equipment operation monitoring system will determine the peak-to-peak value of the water-conducting tile temperature, that is, the peak-to-peak value of the water-conducting tile temperature, as an evaluation indicator corresponding to the water conduction.

[0094] If the difference between the average value of the first water-conductor tile temperature and the average value of the second water-conductor tile temperature is less than the preset threshold corresponding to the average value of the water-conductor tile temperature, the power equipment operation monitoring system will not determine the average value of the water-conductor tile temperature, that is, the average value of the water-conductor tile temperature, as an evaluation indicator corresponding to the water conduction.

[0095] Similarly, for the water-conducting oil temperature and the water-conducting oil level, the process of the power equipment operation monitoring system determining the corresponding evaluation indicators is similar, and this application will not repeat them here.

[0096] In this embodiment, the power equipment operation monitoring system determines the relationship between the historical operation data and the historical operation status of the equipment components at each measurement point according to the measurement points and data indicators, and can determine the measurement points and data indicators of the equipment components that can better reflect whether the power equipment is abnormal, and then obtain the evaluation indicators that can better reflect whether the power equipment is abnormal; the method for determining the evaluation indicators of the power equipment operation status based on the above process no longer relies on the knowledge and experience of experts to determine the evaluation indicators. Therefore, the determined evaluation indicators are not easily affected by subjective factors, thereby improving the reliability of the evaluation results of the power equipment operation status.

[0097] In an exemplary embodiment, there are multiple power devices under each device type; the method for determining the evaluation index of the power device operation status is applied to the power device operation monitoring system, and there are multiple system accounts under the power device operation monitoring system.

[0098] In the above step S208, after determining the evaluation index for evaluating the operating status of the power equipment of each equipment type based on the historical operating data and historical operating status corresponding to the power equipment of each equipment type, the following contents are specifically included: for each power equipment under each equipment type, obtaining the operating data of each equipment component of the power equipment under the corresponding operating conditions; evaluating the operating status of the power equipment according to the evaluation index corresponding to the equipment type and the operating data of each equipment component, and obtaining the operating status evaluation result of the power equipment; determining the associated power equipment of each system account among the power equipment under multiple equipment types; and displaying the operating status evaluation result of the corresponding associated power equipment to each system account through the display page of the power equipment operation monitoring system.

[0099] The associated power equipment of each system account is the power equipment for which the system account has data viewing authority.

[0100] Among them, the operation status evaluation result of the power equipment is used to characterize the operation risk of the power equipment; in specific applications, the power equipment operation monitoring system presets multiple operation status evaluation results, and the operation status evaluation result of the power equipment is any one of the preset multiple operation status evaluation results. In actual applications, the preset multiple operation status evaluation results are normal, caution, abnormal, and warning in order from low to high according to the corresponding operation risks.

[0101] The power equipment operation monitoring system determines the evaluation index based on the above step S208, and is able to evaluate the operating status of each power equipment under each type of equipment; specifically, for each power equipment under each type of equipment, the power equipment operation monitoring system first reads the operating data of each device component of the power equipment under the operating conditions corresponding to the equipment type from the internal data table for storing the operating data of the power equipment; then, the power equipment operation monitoring system calculates the index value of each device component under the corresponding evaluation index based on the operating data of each device component, and evaluates the operating status of the power equipment based on the index value corresponding to each device component, to obtain the operating status evaluation result of the power equipment; then, for each system account, according to the authority information of the system account under the power equipment operation monitoring system, the power equipment operation monitoring system determines at least one power equipment for which the system account has data viewing authority among each power equipment under each type of equipment, as the associated power equipment of the system account; then, the power equipment operation monitoring system displays the operating status evaluation result of its associated power equipment to the system account through its display page.

[0102] The permission information of each system account is used to describe the scope of the data viewing permission of the system account.

[0103] In practical applications, the operating data of each device component of each power device is the operating data of the device component at each corresponding measuring point.

[0104] In this embodiment, the power equipment operation monitoring system determines the evaluation index based on the above step S208, can evaluate the operating status of each power equipment under each type of equipment, and can display the operating status of the corresponding associated power equipment to each system account through the display page of the power equipment operation monitoring system, thereby realizing the visualization of the evaluation results of the operating status of each power equipment; based on the operating status evaluation results, the system user of the system account can monitor the operating status of the power equipment in real time, thereby realizing monitoring and early warning of the power equipment.

[0105] In an exemplary embodiment, each power equipment under multiple equipment types is each power equipment under multiple equipment types in multiple power plants, and each power plant has multiple power equipment under each equipment type; the associated power equipment of each system account is each power equipment under at least one associated power plant for which the system account has data viewing permission.

[0106] Specifically, for each system account, the power equipment operation monitoring system determines, among multiple power plants, at least one associated power plant for which the system account has data viewing authority based on the authority information of the system account under the power equipment operation monitoring system, and then determines each power equipment under the associated power plant of the system account as the associated power equipment of the system account.

[0107] In actual applications, each system account under the power equipment operation monitoring system can be divided into a system account corresponding to a single power plant and a system account corresponding to multiple power plants according to the scope of the corresponding data viewing authority; a system account corresponding to a single power plant has one associated power plant, and a system account corresponding to multiple power plants has multiple associated power plants.

[0108] For example, taking multiple power plants as Plant A, Plant B, Plant C, and Plant D as an example, assuming that system account 1 only has data viewing authority for Plant A, then the associated power plant of system account 1 is Plant A, and the associated power equipment of system account 1 is each turbine, each water inlet valve, each technical water supply pump, each excitation system, each speed governor, each SFC, each GCB, each GIS, each main transformer, and each export busbar of Plant A.

[0109] Assuming that system account 2 only has data viewing authority for Plant A and Plant B, the power plants associated with system account 2 are Plant A and Plant B, and the power equipment associated with system account 2 are each turbine, each water inlet valve, each technical water supply pump, each excitation system, each speed governor, each SFC, each GCB, each GIS, each main transformer, and each export busbar of Plant A and Plant B.

[0110] Assuming that system account 3 has data viewing authority for Plant A, Plant B, Plant C, and Plant D, then the associated power plants of system account 3 are Plant A, Plant B, Plant C, and Plant D, and the associated power equipment of system account 3 are each turbine, each water inlet valve, each technical water supply pump, each excitation system, each speed governor, each SFC, each GCB, each GIS, each main transformer, and each export busbar of Plant A, Plant B, Plant C, and Plant D.

[0111] like Figure 5 As shown, the above steps, through the display page of the power equipment operation monitoring system, display the operation status evaluation result of the corresponding associated power equipment to each system account, specifically include the following steps:

[0112] Step S502, for each system account, when the system account is associated with only one power plant, in response to the system account selecting any one of the equipment type selection controls in the display page, the equipment type corresponding to the selected equipment type selection control is determined as the target equipment type.

[0113] Step S504, based on the display page, display the operating status evaluation results of each associated power equipment of the associated power plant under the target equipment type and the power equipment selection controls corresponding to each associated power equipment of the associated power plant under the target equipment type to the system account.

[0114] Step S506 , in response to the system account selecting any one of the power device selection controls in the display page, determining the associated power device corresponding to the selected power device selection control as the target associated power device.

[0115] Step S508: Based on the display page, the operation evaluation status result of the target-related power equipment is displayed to the system account.

[0116] Among them, there are device type selection controls corresponding to each device type in the display page.

[0117] Specifically, no matter whether the system account is associated with one or more power plants, there is an equipment type selection control corresponding to each equipment type in the display page of the power equipment operation monitoring system. For each system account, when the system account is associated with one power plant, that is, the system account is a system account corresponding to a single power plant, the system user can select the equipment type selection control corresponding to the equipment type he wants to view from each equipment type selection control in the display page based on the system account he logged in. The power equipment operation monitoring system responds to the system account's selection operation on any equipment type selection control, determines the equipment type corresponding to the selected equipment type selection control as the target equipment type, and based on the display page, displays to the system account the operating status evaluation results of each associated power equipment of the associated power plant under the target equipment type, and displays the power equipment selection control corresponding to each associated power equipment of the associated power plant under the target equipment type.

[0118] For example, see Figure 6 The display page displays the main page by default, and there are equipment type selection controls corresponding to each equipment type on the left side of the main page. Assuming that the power plant associated with the system account is Plant A, when the system account selects the equipment type selection control corresponding to "Turbine", the display page enters the sub-page corresponding to the turbine of Plant A, in which the corresponding operating status evaluation results of each turbine of Plant A are displayed.

[0119] Then, based on the system account with which the system user has logged in, the system user can select the power equipment selection control corresponding to the associated power equipment he wants to view from among the various power equipment selection controls in the display page. The power equipment operation monitoring system responds to the system account's selection operation on any power equipment selection control, determines the associated power equipment corresponding to the selected power equipment selection control as the target associated power equipment, and displays the operation evaluation results of the associated power equipment to the system account based on the display page.

[0120] For example, see Figure 7 When the system account selects the power equipment selection control corresponding to "Turbine 1", the display page enters the sub-page corresponding to the turbine 1 of Plant A, in which the operation evaluation results of the turbine 1 of Plant A are displayed.

[0121] It is easy to understand that Figure 6 and Figure 7 It is only used to illustrate this embodiment and is not used to limit the device types, measurement points and display pages in this application.

[0122] In actual applications, visual charts of operating data can also be displayed on the display page.

[0123] In this embodiment, the power equipment operation monitoring system can display the corresponding operation status evaluation results in an organized, sequential and hierarchical manner through various selection controls in the display page, thereby increasing the orderliness and logic of the visualization of the operation status evaluation results of the power equipment.

[0124] In an exemplary embodiment, Figure 8 As shown, the above steps, through the display page of the power equipment operation monitoring system, display the operation status evaluation result of the corresponding associated power equipment to each system account, and further specifically include the following steps:

[0125] Step S802, for each system account, when the system account is associated with multiple power plants, in response to the system account selecting any one of the equipment type selection controls in the display page, the equipment type corresponding to the selected equipment type selection control is determined as the target equipment type.

[0126] Step S804, based on the display page, display the operating status evaluation results of each associated power equipment of each associated power plant of the system account under the target equipment type and the power plant selection controls corresponding to each associated power plant of the system account to the system account.

[0127] Step S806 , in response to the system account selecting any one of the power plant selection controls in the display page, determining the associated power plant corresponding to the selected power plant selection control as the target associated power plant.

[0128] Step S808, based on the display page, display the operating status evaluation results of each associated power equipment of the target associated power plant under the target equipment type, and the power equipment selection controls corresponding to each associated power equipment of the target associated power plant under the target equipment type to the system account.

[0129] Step S810, in response to a selection operation of a system account on any one of the power device selection controls in the display page, an associated power device corresponding to the selected power device selection control is determined as a target associated power device.

[0130] Step S812: Based on the display page, the operating status evaluation result of the target-related power equipment is displayed to the system account.

[0131] Among them, there are device type selection controls corresponding to each device type in the display page.

[0132] Specifically, no matter whether the system account is associated with one or more power plants, the display page of the power equipment operation monitoring system has a device type selection control corresponding to each device type. For each system account, when the system account is associated with more than one power plant, that is, the system account is a system account corresponding to multiple power plants, the system user can select the device type selection control corresponding to the device type he wants to view from each device type selection control in the display page based on the system account he logged in. The power equipment operation monitoring system responds to the system account's selection operation on any one of the device type selection controls, determines the device type corresponding to the selected device type selection control as the target device type, and displays the operating status evaluation results of each associated power device of each associated power plant of the system account under the target device type to the system account based on the display page, and displays the power plant selection control corresponding to each associated power plant of the system account.

[0133] For example, see Fig. 9 The display page displays the main page by default, and there are equipment type selection controls corresponding to each equipment type on the left side of the main page. Assuming that the power plants associated with the system account are Plant A, Plant B, and Plant C, when the system account selects the equipment type selection control corresponding to "Turbine", the display page enters the sub-page corresponding to the turbines of all associated power plants. In this sub-page, the operating status evaluation results of each turbine of Plant A, Plant B, and Plant C are displayed, as well as the power plant selection controls corresponding to Plant A, Plant B, and Plant C.

[0134] Then, based on the system account with which the system user has logged in, the system user can select the power plant selection control corresponding to the associated power plant that he wants to view from the various power plant selection controls in the display page. The power equipment operation monitoring system responds to the system account's selection operation on any power plant selection control, determines the associated power plant corresponding to the selected power plant selection control as the target associated power plant, and displays the operating status evaluation results of each associated power equipment under the target equipment type of the target associated power plant to the system account based on the display page, as well as the power equipment selection control corresponding to each associated power equipment under the target equipment type of the target associated power plant.

[0135] For example, see Fig.10 When the system account selects the power plant selection control corresponding to "Plant A", the display page enters the sub-page corresponding to the turbine of Plant A. In this sub-page, the operating status evaluation results of each turbine of Plant A and the power equipment selection controls corresponding to each turbine of Plant A are displayed.

[0136] Then, based on the system account with which the system user has logged in, the system user can select the power equipment selection control corresponding to the associated power equipment he wants to view from the various power equipment selection controls in the display page. The power equipment operation monitoring system responds to the system account's selection operation on any power equipment selection control, determines the associated power equipment corresponding to the selected power equipment selection control as the target associated power equipment, and displays the operating status evaluation result of the target associated power equipment to the system account based on the display page.

[0137] For example, see Fig.11 When the system account selects the power equipment selection control corresponding to "Turbine 1", the display page enters the sub-page corresponding to the turbine 1 of Plant A, in which the operating status evaluation results of the turbine 1 of Plant A are displayed.

[0138] It is easy to understand that Fig. 9 , Fig.10 and Fig.11 It is only used to illustrate this embodiment and is not used to limit the device types, device measurement points and display pages in this application.

[0139] In actual applications, visual charts of operating data can also be displayed on the display page.

[0140] In this embodiment, the power equipment operation monitoring system can display the corresponding operation status evaluation results in an organized, sequential and hierarchical manner through various selection controls in the display page, thereby increasing the orderliness and logic of the visualization of the operation status evaluation results of the power equipment.

[0141] In an exemplary embodiment, the operation data monitoring method of the power equipment provided in the present application also includes the following contents: when a configuration modification request sent by any system account is received 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.

[0142] Among them, the configuration information includes the equipment type corresponding to the power equipment operation monitoring system, the measuring point corresponding to each equipment type, the power plant corresponding to the power equipment operation monitoring system, the power equipment under each power plant, the system account corresponding to the power equipment operation monitoring system, the associated power plant of each system account, and at least one of the preset multiple data indicators.

[0143] In an exemplary embodiment, if Fig.12 As shown, another method for determining the evaluation index of the operating status of electric power equipment is provided, and the method is applied to the electric power equipment operation monitoring system as an example for explanation, including the following steps:

[0144] Step S1202: determining multiple types of power equipment for which operation status evaluation is to be performed.

[0145] Step S1204: determining the operating conditions of the power equipment of each equipment type and at least one equipment component constituting the power equipment of each equipment type.

[0146] Step S1206, obtaining the historical operation data of each device component of the power equipment of each device type under the corresponding operation conditions, and the historical operation status of the power equipment of each device type under the corresponding operation conditions.

[0147] Step S1208, for each type of electrical equipment, the time period in the historical time interval corresponding to the electrical equipment of the equipment type, in which the corresponding historical operating status is abnormal, is determined as an abnormal time period, and the time period in the historical time interval in which the corresponding historical operating status is normal, is determined as a normal time period.

[0148] Step S1210 , determining the first operating data of each device component in an abnormal time period and the second operating data in a normal time period from the historical operating data of each device component of the power equipment of the device type.

[0149] Step S1212, for each measuring point of the equipment component, determine the first indicator value of the first operating data of the equipment component at the measuring point under each data indicator among the preset multiple data indicators, and determine the second indicator value of the second operating data of the equipment component at the measuring point under each data indicator; each data indicator is used to characterize the distribution of data.

[0150] Step S1214: for each data indicator, when the difference between the first indicator value and the second indicator value under the data indicator is greater than or equal to the corresponding preset threshold, the data indicator under the measuring point is determined as an evaluation indicator corresponding to the equipment component.

[0151] Step S1216: Determine the evaluation index corresponding to each device component as the evaluation index for evaluating the operating status of the power equipment of the device type.

[0152] In the present embodiment, the power equipment operation monitoring system can determine, for each type of power equipment, an evaluation index for evaluating the operating status of the power equipment of this type of equipment based on the historical operating status of the power equipment of this type of equipment under corresponding operating conditions and in historical time intervals, as well as the historical operating data of each equipment component corresponding to the power equipment of this type of equipment in historical time intervals. The method for determining the evaluation index of the operating status of power equipment based on the above process no longer relies on the knowledge and experience of experts to determine the evaluation index. Therefore, the determined evaluation index is not easily affected by subjective factors, thereby improving the reliability of the evaluation results of the operating status of the power equipment.

[0153] In order to more clearly illustrate the method for determining the evaluation index of the operating status of the power equipment provided in the embodiment of the present application, the method for determining the evaluation index of the operating status of the power equipment is specifically described below with a specific embodiment, but it should be understood that the embodiment of the present application is not limited thereto.
