[0002] The power plant unit equipment includes a variety of equipment, such as boiler equipment, steam turbines, generators, electrical systems, water treatment equipment, control equipment, etc., which realize power generation operations through the operation between equipment; in addition, when each equipment leaves the factory, in order to avoid the situation where equipment failure cannot be discovered in time, all equipment in the power plant unit is set with its corresponding initial fault alarm threshold, and an early warning is issued when the relevant parameters of the equipment reach a certain threshold.

[0003] However, the inventors of the present application discovered that there are operational correlations between devices, that is, when a certain device fails, it will affect the normal operation of other devices, causing failures or even damage to other devices; that is, when a certain device fails, other devices are affected by the failure of the certain device, and other devices have associated time-delay failures; in this case, the relevant parameters that can reflect the failure of other devices need to reach the failure threshold set when the equipment leaves the factory before a failure warning can be issued for them. At this time, other devices may suffer irreversible damage, that is, while the failure of other related devices cannot be detected quickly, the chain loss of other related devices is also increased.

DETAILED DESCRIPTION

[0042] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the drawings in the embodiments of the present application are collected below to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] The embodiment of the present application provides a method for early warning of power plant unit equipment failure, which can be executed by an electronic device, wherein the electronic device can be a server or a terminal device, wherein the server can be an independent physical server, or a server cluster or distributed device composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, which is not limited in the embodiment of the present application.

[0045] Reference Figure 1 A method for early warning of power plant unit equipment failure includes: step S101, step S102 and step S103, wherein:

[0046] S101, when the fault warning information of the current device is obtained, the fault information and device operating parameters of the current device are obtained.

[0047] In some embodiments, the fault warning information is alarm information generated when an operation fault occurs in the current device and the operation parameters exceed the normal operation parameter range.

[0048] The electronic equipment monitors the operation status of all equipment included in the power plant unit in real time, and obtains various parameters of each equipment during operation in real time; when the alarm device issues a fault warning information, the electronic equipment obtains the fault information of the current equipment and the equipment operation parameters of the current equipment corresponding to the fault warning information through the relevant monitoring devices installed on the current equipment.

[0049] In some embodiments, in the process of obtaining fault warning information of the current device and obtaining the fault information and device operating parameters of the current device, the electronic device obtains the device type of the current device; determines whether the device type is a preset device type; if it is determined that the device type is the preset device type, obtains the fault information and device operating parameters of the current device; if it is determined that the device type is not the preset device type, indicating that the fault of the current device will have a serious impact on all equipment of the power plant unit, the electronic device does not make subsequent adjustments to the alarm thresholds of other equipment that has an operation-related relationship with the current device based on the acquired fault information and device operating parameters of the current device.

[0050] For example, the current device is a main power supply device that supplies power to the equipment of a power plant unit. If an abnormality occurs in the main power supply device and an alarm is sounded, it will affect the normal operation of all equipment of the power plant unit. At this time, it is meaningless to adjust the alarm threshold of the equipment of the power plant unit. Subsequently, the electronic equipment will not adjust the alarm threshold of other equipment that has an operation-related relationship with the current device based on the fault information and equipment operating parameters of the current device.

[0051] S102: Determine device association parameters corresponding to the current device based on the device operating parameters and the acquired historical operating parameters.

[0052] In some embodiments, the historical operating parameters are parameters when the current device is in normal operation; wherein the historical operating parameters include connection parameters between the current device and other devices, etc.; the device operating parameters are various parameters during the operation of the current device;

[0053] The electronic device can determine the connection status between the current device and other devices through historical operating parameters, and determine the target device operating parameters associated with other devices from the device operating parameters through the device connection status, and determine the change of the target device operating parameters based on the changes between the historical operating parameters and the target device operating parameters, and then determine the device association parameters corresponding to the current device based on the change of the target device operating parameters.

[0054] S103: Determine associated fault information of the target device based on the fault information and the device associated parameters.

[0055] In some embodiments, the fault information includes information such as abnormal parameters, changes in abnormal parameters, and causes of the fault; the device-associated parameters include connection parameters between the current device and a target device with which the current device is associated in operation.

[0056] The electronic device determines the connection parameters of the current device contained in the device-associated parameters, and determines the target device associated with the current device from multiple devices of the power plant unit based on the connection parameters, and retrieves the device parameters of the target device that are associated with the operation of the current device; at the same time, the electronic device analyzes and processes the fault information to determine the abnormal parameters contained therein and the changes in the abnormal parameters; based on the device-associated parameters and the abnormal parameters, the electronic device determines the target device parameters from the device parameters of the retrieved target device, and determines the changes in the target device parameters based on the changes in the abnormal parameters contained in the fault information and the device-associated parameters, and determines the associated fault information corresponding to the target device through the changes.

[0057] S104, obtaining an initial alarm threshold of the target device, and determining a target alarm threshold corresponding to the target device based on the initial alarm threshold and associated fault information;

[0058] S105: When the operating parameters of the target device reach the target alarm threshold, generate fault warning information corresponding to the target device.

[0059] In some embodiments, the electronic device retrieves the alarm threshold set when the target device leaves the factory, i.e., the initial alarm threshold, and determines the change in fault parameters corresponding to the target device when the initial alarm threshold is issued. At the same time, the electronic device determines the change in fault parameters corresponding to the associated fault occurring in the target device based on the associated fault information, and resets the alarm threshold of the target device based on the change in fault parameters corresponding to the initial alarm threshold and the change in fault parameters corresponding to the associated fault occurring, i.e., sets the target alarm threshold; wherein the set target alarm threshold is less than the initial alarm threshold.

[0060] Subsequently, the electronic equipment continuously monitors the changes in the operating parameters of the target device. When the operating parameters of the target device reach the target alarm threshold, it generates fault warning information for the target device and sends the fault warning information to the monitoring terminal installed in the monitoring center, thereby improving the efficiency of fault warning for the target device. By resetting the initial alarm threshold, a fault warning is issued when the set target alarm threshold is reached, thereby avoiding damage to the target device and reducing the chain loss of the target device caused by the failure of the current device.

[0061] The embodiment of the present application provides a method for early warning of equipment failure of a power plant unit. When the electronic device obtains the fault early warning information of the current equipment in the power plant unit, the electronic device obtains the fault information and equipment operating parameters of the current equipment. At the same time, the electronic device obtains the historical operating parameters, and determines the equipment associated parameters corresponding to the current equipment based on the equipment operating parameters and the historical operating parameters. The equipment associated parameters can clarify the association between the current equipment and other equipment, and then the associated fault information of the target equipment in other equipment that is negatively affected by the failure of the current equipment can be determined based on the equipment associated parameters and the fault information. Subsequently, the electronic device obtains the initial alarm threshold of the target equipment, and determines the target alarm threshold corresponding to the target equipment based on the initial alarm threshold and the associated fault information. The target alarm threshold is used as a new early warning standard for the target equipment. When the operating parameters of the target equipment reach the target alarm threshold, the electronic device generates the fault early warning information corresponding to the target equipment, thereby avoiding the situation that the operating parameters of the target equipment associated with the current equipment need to reach the factory set alarm threshold before the fault early warning information is generated due to the failure of the current equipment, resulting in damage to the target equipment, thereby improving the early warning efficiency of other equipment except the currently failed equipment, and reducing the chain loss caused by the currently failed equipment.

[0062] In step S102, based on the device operating parameters and the acquired historical operating parameters, the device association parameters corresponding to the current device are determined, including: based on the historical operating parameters, determining the device connection information corresponding to the current device; based on the device connection information, filtering out the target device operating parameters from the device operating parameters; based on the historical operating parameters, determining the parameter change information of the target device operating parameters; based on the parameter change information and the target device operating parameters, determining the device association parameters corresponding to the current device.

[0063] In some embodiments, the historical operating parameters include the connection parameters between the current device and other devices, and also include the operating parameters of the current device and other devices during operation; the target device operating parameters are device operating parameters of the current device that are associated with the operation of other devices; the parameter change information is the normal change range of the target device operating parameters when the current device operates normally.

[0064] The electronic device determines device connection information between the current device and other devices based on historical operating parameters, and screens the device operating parameters of the current device based on the device connection information to determine target device operating parameters with operation associations; then, the electronic device determines parameter change information of the target device operating parameters when the current device is in normal operation based on the historical operating parameters; the electronic device integrates the parameter change information, the target device operating parameters, and the connection information corresponding to the target device operating parameters to determine device association parameters corresponding to the current device.

[0065] In step S103, the associated fault information of the target device is determined based on the fault information and the device-associated parameters, including: determining multiple device parameters of the target device based on the device-associated parameters; determining abnormal parameters of the current device and a first parameter change of the abnormal parameters based on the fault information; determining the target device parameters from multiple device parameters based on the device-associated parameters and the abnormal parameters; determining a second parameter change of the target device parameters based on the first parameter change and the device-associated parameters; and determining the associated fault information of the target device based on the second parameter change.

[0066] In some embodiments, the electronic device determines the target device from a large number of devices in a power plant unit based on the connection information included in the device association information, and retrieves multiple device parameters of the target device that are associated with the target device operating parameters; and the electronic device analyzes and processes the fault information to determine the abnormal parameters contained therein and the first parameter change of the abnormal parameters; then, the electronic device determines the target device operating parameters that match the abnormal parameters from the device association parameters based on the abnormal parameters, and determines the target device parameters that are associated with the target device operating parameters from multiple device parameters based on the target device operating parameters corresponding to the abnormal parameters; then, the electronic device monitors in real time, based on the first parameter change and the target device parameters included in the device association parameters, the second parameter change of the target device parameters during the process of the target device parameters changing based on the first parameter change, and uses the target device parameters and their second parameter change as the associated fault information of the target device.

[0067] In step S104, based on the initial alarm threshold and the associated fault information, the target alarm threshold corresponding to the target device is determined, including: based on the associated fault information, determining the associated fault parameters corresponding to the target device; determining the fault parameter change ratio between the initial alarm threshold and the associated fault parameters; based on the fault parameter change ratio, determining the target alarm threshold corresponding to the target device.

[0068] In some embodiments, the initial alarm threshold represents that when a target device fails, the operating parameter corresponding to the fault reaches the warning parameter value; the associated fault parameter is the peak value of the second parameter change corresponding to the target device parameter included in the associated fault information.

[0069] The electronic device determines the associated fault parameter corresponding to the target device based on the second parameter change corresponding to the target device parameter contained in the associated fault information, and calculates the ratio of the associated fault parameter to the initial alarm threshold to determine the fault parameter change ratio between the initial alarm threshold and the associated fault parameter. When the fault parameter change ratio is greater than the preset fault parameter change ratio, the electronic device defines the associated fault parameter as the target alarm threshold, and when the target device parameter reaches the target alarm threshold, the electronic device generates a fault warning information.

[0070] In some embodiments, when a current device included in a power plant unit fails, at least two devices associated with the current device are negatively affected, that is, the device operating parameters of the at least two devices are affected, and there may also be a master-slave relationship between the at least two devices. At this time, when the current device fails, the device with the master relationship is affected by the failure of the current device, and the device with the slave relationship is affected by the failure of the current device as well as the device with the master relationship; in this case, the reset target alarm threshold of the device with the master relationship can be considered as the target alarm threshold of the device with the slave relationship.

[0071] That is, the target device may include at least two sub-target devices; the associated fault information includes at least two sub-associated fault information, wherein at least two sub-target devices correspond to at least two sub-associated fault information; at this time, in step S104, based on the initial alarm threshold and the associated fault information, the target alarm threshold corresponding to the target device is determined, specifically including: when there is a master-slave relationship between at least two sub-target devices and the initial alarm thresholds of at least two sub-target devices are equal, determining the first fault parameter change ratio corresponding to the sub-target device with the master relationship and the second fault parameter change ratio corresponding to the sub-target device with the slave relationship; based on the first fault parameter change ratio, determining the first target alarm threshold corresponding to the sub-target device with the master relationship; based on the second fault parameter change ratio, determining the second target alarm threshold corresponding to the sub-target device with the master relationship; based on the first fault parameter change ratio and the second fault parameter change ratio, eliminating the second target alarm threshold, and using the first target alarm threshold as the target alarm threshold for at least two sub-target devices.

[0072] In some embodiments, the electronic device obtains the device type and connection mode of at least two sub-target devices, and determines the relationship between the at least two sub-target devices based on the device type and the connection mode; when the electronic device determines that there is a master-slave relationship between the at least two sub-target devices and the initial alarm thresholds of the at least two sub-target devices are equal, the electronic device first obtains the first operating parameter and the first initial alarm threshold when the sub-target device with the master relationship is in normal operation, and obtains the second operating parameter and the second initial alarm threshold when the sub-target device with the slave relationship is in normal operation; the electronic device calculates the ratio of the first operating parameter to the first initial alarm threshold to determine the first fault parameter change ratio; and calculates the ratio of the second operating parameter to the second initial alarm threshold to determine the second fault parameter change ratio; then, the electronic device determines the relationship between the first fault parameter change ratio and the second fault parameter change ratio, and when the relationship satisfies the preset relationship, the electronic device eliminates the second target alarm threshold and uses the first target alarm threshold as the alarm threshold for at least two sub-target devices.

[0073] In some embodiments, based on the first fault parameter change ratio and the second fault parameter change ratio, the second target alarm threshold is eliminated, and the first target alarm threshold is used as the target alarm threshold for at least two sub-target devices, including: comparing the first fault parameter change ratio with the preset fault parameter change ratio and the first fault parameter change ratio, respectively; when the first fault parameter change ratio exceeds the preset fault parameter change ratio, and the first fault parameter change ratio is greater than the second fault parameter change ratio, the second target alarm threshold is eliminated, and the first target alarm threshold is used as the target alarm threshold for at least two sub-target devices.

[0074] In some embodiments, the electronic device compares the first fault parameter change ratio with the preset fault parameter change ratio, and at the same time compares the first fault parameter change ratio with the second fault parameter change ratio; when the electronic device determines that the first fault parameter change ratio exceeds the preset fault parameter change ratio, it indicates that the sub-target device of the main relationship corresponding to the first fault parameter change ratio is greatly affected by the current device failure and may be damaged in the future. At this time, the alarm threshold of the sub-target device of the main relationship can be reset.

[0075] When the electronic device determines that the proportion of the first fault parameter is greater than the proportion of the second fault parameter change, it indicates that the sub-target device of the master relationship is affected by the current device failure more than the sub-target device of the slave relationship corresponding to the second fault parameter proportion is affected by the current device failure. In the subsequent period, as the degree of influence of the sub-target device of the master relationship increases, the sub-target device of the slave relationship is affected by both the sub-target device of the master relationship and the current device, and the probability of damage will further increase.

[0076] Therefore, when the first fault parameter change ratio exceeds the preset fault parameter change ratio, and the first fault parameter change ratio is greater than the second fault parameter change ratio, the electronic device will eliminate the second target alarm threshold and will not use it as the new alarm threshold for the sub-target device in the slave relationship, and will use the first target alarm threshold as the alarm threshold for the sub-target device in the master-slave relationship, thereby reducing the possibility of damage to at least two sub-target devices in the master-slave relationship due to the current device failure.

[0077] In some embodiments, when an instruction to complete equipment maintenance is obtained, it indicates that the current equipment maintenance has been completed and can operate normally. At this time, there is no need to control the target equipment to issue an early warning based on the determined target alarm threshold. The electronic device then obtains the first maintenance completion operating parameter of the target equipment; and brings the first maintenance completion operating parameter into the preset operating parameter range for comparison; when the electronic device determines that the first maintenance completion operating parameter is within the preset operating parameter range, it further indicates that the current equipment operation is complete, and the electronic device then generates an alarm threshold recovery instruction, and based on the alarm threshold recovery instruction, restores the target alarm threshold to the initial alarm threshold.

[0078] The present application provides a power plant unit equipment failure early warning system, which adopts the following technical solutions;

[0079] Reference Figure 2 A power plant unit equipment fault warning system 20 includes: a parameter acquisition module 201, an equipment associated parameter determination module 202, an associated fault information determination module 203, an alarm threshold determination module 204 and a fault warning information generation module 205, wherein:
