Description

Technical Field

[0001] This invention belongs to the field of new energy power station management technology, and specifically relates to a method for configuring custom alarm rules and related devices. Background Technology

[0002] The Supervisory Control and Data Acquisition (SCADA) system is the core of the entire new energy power station equipment operation monitoring, undertaking key tasks such as data acquisition, equipment monitoring, and alarm notification; among them, the alarm notification function is an important link to ensure the safe and stable operation of equipment.

[0003] Currently, alarm rule configurations in SCADA systems are typically divided into digital alarm rules and analog alarm rules. Digital and analog alarms are relatively simple and direct, with their alarm triggering conditions based on the state or value of a single measuring point. However, the aforementioned traditional alarm rules generally alert by monitoring a measuring point to a certain value, resulting in poor accuracy. This forces monitoring personnel to query other measuring points to comprehensively analyze the cause and specific problem of the alarm, which can easily lead to delays in alarm information. This poses a potential risk to the equipment safety of new energy power plants and seriously affects the operational safety and stability of the system. Summary of the Invention

[0004] To address the technical problems existing in the prior art, this invention provides a method and related apparatus for configuring custom alarm rules, in order to solve the technical problem that the accuracy of alarm prompts provided by traditional alarm rules is poor, which easily leads to delays in alarm information.

[0005] In the past, configuring alarm calculation formulas was inefficient and prone to errors.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: This invention provides a method for configuring custom alarm rules, including: Determine the information of several monitoring points for the equipment to be monitored in the new energy power station; Based on the information of several measuring points of the equipment to be monitored in the new energy power station, and combined with the predetermined alarm requirements of the equipment, an alarm rule expression for the target measuring point of the equipment to be monitored is constructed. Save the alarm rule expressions of the target measurement points in the monitored equipment to the preset system database or configuration file to obtain the custom alarm rule configuration results, which are used as the alarm information configuration results.

[0007] Furthermore, the information from several measurement points of the device under monitoring includes the device's operating parameters, environmental parameters, and status variables.

[0008] Furthermore, based on the information from several measuring points of the equipment to be monitored in the new energy power station, and combined with the predetermined equipment alarm requirements, the process of constructing alarm rule expressions for the target measuring points of the equipment to be monitored is as follows: Based on the predetermined equipment alarm requirements, and using preset logical operators or data relationships, the conditional judgment expressions of several measurement point information of the equipment to be monitored are combined to obtain the alarm rule expression of the target measurement point in the equipment to be monitored.

[0009] Furthermore, the alarm rule expression for the target measurement point in the monitored device can take the form of a Boolean expression, a threshold comparison expression, or a function calculation expression.

[0010] Furthermore, the preset system database includes a relational database or time-series database in the new energy power station system, and the preset configuration file is a JSON format file in the new energy power station system.

[0011] This invention also provides a custom alarm rule configuration system, including: The measurement point determination module is used to determine the measurement point information of several monitoring devices in the new energy power station; The expression configuration module is used to construct alarm rule expressions for target measurement points in the monitored equipment based on information from several measurement points of the equipment to be monitored in the new energy power station, combined with predetermined equipment alarm requirements. The expression storage module is used to save the alarm rule expressions of the target measurement points in the monitored equipment to a preset system database or configuration file, and obtain the custom alarm rule configuration results as the alarm information configuration results.

[0012] Furthermore, based on the information from several measuring points of the equipment to be monitored in the new energy power station, and combined with the predetermined equipment alarm requirements, the process of constructing alarm rule expressions for the target measuring points of the equipment to be monitored is as follows: Based on the predetermined equipment alarm requirements, and using preset logical operators or data relationships, the conditional judgment expressions of several measurement point information of the equipment to be monitored are combined to obtain the alarm rule expression of the target measurement point in the equipment to be monitored.

[0013] The present invention also provides an electronic device, comprising: A processor is used to execute computer programs; A computer-readable storage medium storing a computer program, which, when executed by the processor, performs the custom alarm rule configuration method.

[0014] The present invention also provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the custom alarm rule configuration method described above.

[0015] The present invention also provides a computer program product, which includes a computer program that, when executed by a processor, implements the custom alarm rule configuration method.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The custom alarm rule configuration method provided by this invention determines several monitoring points and, in conjunction with pre-determined alarm requirements, configures alarm rule expressions for the target monitoring points. It then sets alarm triggering conditions by integrating information from multiple monitoring points. The configured alarm rule expressions are saved to obtain the custom alarm rule configuration result, thereby enabling customized settings for alarm functions in the operation monitoring of new energy power plant facilities. This invention avoids inaccurate alarm prompts caused by single-point data by configuring alarm rule expressions that integrate information from multiple monitoring points, rather than triggering alarms based solely on the status or value of a single monitoring point. This allows for more accurate alarm prompts and reduces unnecessary query operations performed by monitoring personnel due to inaccurate alarms.

Detailed Implementation

[0020] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] This invention provides a method for configuring custom alarm rules, comprising the following steps: Step 100: Determine the information of several measuring points of the equipment to be monitored in the new energy power station.

[0022] Step 200: Based on the information of several measuring points of the equipment to be monitored in the new energy power station, and combined with the predetermined alarm requirements of the equipment, construct the alarm rule expression of the target measuring point in the equipment to be monitored.

[0023] Step 300: Save the alarm rule expression of the target measurement point in the device to be monitored to the preset system database or configuration file to obtain the custom alarm rule configuration result.

[0024] The custom alarm rule configuration method described in this invention comprehensively combines information from multiple relevant measurement points to configure alarm rule expressions, greatly improving alarm accuracy and enabling monitoring personnel to quickly and accurately locate problems. It reduces the tedious workload of monitoring personnel searching other measurement points to analyze alarm causes, thus improving work efficiency. Furthermore, it allows for flexible customization of alarm rules based on the equipment, operating scenarios, and monitoring needs of different new energy power stations, demonstrating strong adaptability. This effectively enhances the safety and stability of new energy power station equipment operation, reduces the risk of failure and economic losses, and comprehensively ensures the efficient and stable operation of the power station.

[0025] The following specific embodiments further explain the custom alarm rule configuration method provided by the present invention: Example 1 As attached Figure 1 As shown, this embodiment 1 provides a method for configuring custom alarm rules, including the following steps: Step 1: Determine several measurement point information for the equipment to be monitored in the new energy power station. This measurement point information includes the equipment's operating data, environmental parameters, and status variables. It should be noted that the measurement point information refers to the data points that need to be collected and monitored within the monitored equipment or components; for example, temperature sensor data, switch status information, or voltage and current data. Determining several measurement point information provides a multi-dimensional data foundation for alarm rules, avoiding misjudgments caused by a single measurement point.

[0026] Step 2: Based on the measurement point information of several monitoring points in the new energy power station and combined with the predetermined equipment alarm requirements, construct alarm rule expressions for the target measurement points in the monitoring equipment. Specifically, the construction process is as follows: Based on the predetermined alarm requirements, the alarm rule expression of the target measurement point in the monitored device is obtained by combining the conditional judgment expressions of several measurement point information of the monitored device using preset logical operators or data relationships; wherein, the form of the alarm rule expression of the target measurement point in the monitored device includes Boolean expression, threshold comparison expression or function calculation expression. It should be noted that by combining conditional statements based on logical operators or mathematical relationships with information from multiple measurement points, an alarm rule expression for the target side of the monitored device can be obtained. This can be achieved through Boolean expressions, threshold comparisons, or function calculations. For example, comparing the numerical difference between two measurement points with a preset range. Configuring the alarm rule expression by combining conditional statements with information from multiple measurement points can comprehensively consider the correlation between them, improving the accuracy of alarm triggering. Example explanation: Taking TEST_5_002_PA in a certain new energy power station as an example, when it is determined that the value of this measuring point is greater than 10, an alarm rule expression for triggering a certain preset alarm is given, for example: av("TEST_5_002_PA")≥10; Step 3: Save the alarm rule expressions of the target measurement points in the monitored equipment to the preset system database or configuration file to obtain the custom alarm rule configuration results. The preset system database includes a relational database or time-series database in the new energy power station system, and the preset configuration file is a JSON format file in the new energy power station system. By saving the configuration results, alarm rules can be reused and dynamically updated, ensuring that the monitoring system continuously adapts to actual needs.

[0027] Configuration principle explanation: The custom alarm rule configuration method described in Embodiment 1 determines several measurement point information of the equipment to be monitored in the new energy power station. According to the actual alarm scenario requirements, the correlation between measurement points is transformed into expressions through logical operators or data relationships. For example, in the vibration monitoring of wind turbine generator sets, if it is necessary to trigger an alarm when the gearbox temperature exceeds the threshold and the vibration amplitude is abnormal at the same time, the real-time data of the temperature measurement point and the vibration measurement point can be combined into an expression through "AND" logic. After the expression is saved to the system, the monitoring program will parse and execute the rule in real time, and trigger an alarm only when both measurement points meet the conditions at the same time, thereby reducing false alarms caused by fluctuations of a single measurement point.

[0028] It should be noted that existing alarm configurations rely solely on the status or value of a single measuring point, such as monitoring only whether the temperature exceeds the limit. This solution, however, introduces an expression combining multiple measuring points, which can reflect the complex correlations of equipment operating status. For example, when determining whether a pump unit is leaking, existing technology requires operators to manually check the pressure, flow, and temperature measuring points separately and perform manual analysis. However, the method in Embodiment 1 can directly configure an expression for "pressure drop rate exceeding a threshold and flow rate remaining at zero," automatically triggering an alarm and reducing manual intervention.

[0029] The custom alarm rule configuration method described in Embodiment 1 can generate accurate alarm triggering conditions based on the correlation between multiple measurement points, effectively reducing the probability of false alarms or missed alarms caused by anomalies in a single measurement point, while also reducing the workload of monitoring personnel in manually verifying data from multiple measurement points and improving the automation level of the monitoring system.

[0030] Example 2 As attached Figure 2 As shown in the figure, this embodiment 2 provides a custom alarm rule configuration system, including a measurement point determination module, an expression configuration module, and an expression storage module.

[0031] The measurement point determination module is used to determine the measurement point information of several monitoring points of the equipment to be monitored in the new energy power station.

[0032] The expression configuration module is used to construct alarm rule expressions for target measurement points in the monitored equipment based on information from several measurement points of the equipment to be monitored in the new energy power station, combined with predetermined equipment alarm requirements.

[0033] The expression storage module is used to save the alarm rule expressions of the target measurement points in the monitored equipment to a preset system database or configuration file, and obtain the custom alarm rule configuration results as the alarm information configuration results.

[0034] Optionally, the expression configuration module is specifically used to combine conditional judgment expressions of several measurement point information of the device to be monitored with preset logical operators or data relationships according to the predetermined device alarm requirements, so as to obtain the alarm rule expression of the target measurement point in the device to be monitored.

Those skilled in the art will understand that the above are examples of electronic devices and do not constitute a limitation on the electronic device. It may include more components than described above, or combine certain components, or different components. For example, the electronic device may also include a communication interface, input / output devices, network access devices, and a bus.

[0039] The processor can be a central processing unit, or other general-purpose processors, digital signal processors, application-specific integrated circuits (ASICs), off-the-shelf programmable gate arrays (OPGs) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. A general-purpose processor can be a microprocessor, or any conventional processor. The processor is the control center of the electronic device, connecting various parts of the electronic device via various communication interfaces and lines.

[0040] The memory can be used to store the computer program and / or module. The processor implements various functions of the electronic device by running or executing the computer program and / or module stored in the memory and by calling the data stored in the memory.

[0041] The memory may primarily include a program storage area and a data storage area. The program storage area may store the operating system and at least one application program required for a given function (such as sound playback, image playback, etc.). The data storage area may store data created based on the use of the mobile phone (such as audio data, phonebook, etc.).

[0042] Example 4 This embodiment 4 also provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the custom alarm rule configuration method described above.

[0043] If the modules / units integrated into the custom alarm rule configuration system are implemented as software functional units and sold or used as independent products, they can be stored in a computer-readable storage medium.

[0044] Based on this understanding, the present invention can implement all or part of the processes in the above-described custom alarm rule configuration method, or it can be accomplished by a computer program instructing related hardware.

The program can be stored in a computer-readable storage medium, and when executed, it can include the processes of the embodiments of the above methods.

[0048] The custom alarm rule configuration method described in this invention determines several measurement points that need to be monitored and configures alarm rule expressions based on predetermined alarm requirements. In this case, alarm triggering no longer depends on a single measurement point but comprehensively considers the status and values ​​of multiple related measurement points. For example, in a device to be monitored at a new energy power station, multiple measurement points such as voltage, current, and power are included in the monitoring scope, and corresponding alarm rule expressions are configured. Specifically, an alarm is triggered only when the voltage exceeds a threshold, the current is below a certain range, or the power exhibits abnormal fluctuations. This multi-measurement comprehensive judgment method can more accurately reflect the actual operating status of the equipment, greatly improving the accuracy of alarms and enabling monitoring personnel to obtain equipment fault information more promptly and accurately.

[0049] Furthermore, by configuring alarm rule expressions that integrate information from multiple measurement points, this invention enables a comprehensive judgment of the status and values ​​of multiple related measurement points when an alarm is triggered. The alarm information received by monitoring personnel is based on a more comprehensive and accurate analysis, eliminating the need to spend considerable time querying data from other measurement points for integrated analysis. For example, after an alarm rule configured according to this method is triggered, monitoring personnel can directly understand from the alarm information that the abnormal situation is caused by the combined effect of multiple related measurement points, thereby quickly locating the root cause of the problem and taking appropriate measures. This significantly reduces the workload of monitoring personnel and improves work efficiency, making it particularly suitable for scenarios with numerous and complex equipment, such as new energy power plants.
