[0061] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0062] The secure and stable control method for a power system based on standardized program configuration provided by the embodiments of the present application can be applied to an application environment as Figure 1 shown, including a secure and stable control device 102 for a power system and a power system 104. Among them, the secure and stable control device 102 for a power system includes a human-computer interaction layer and an internal standardized program configuration layer. The secure and stable control device 102 responds to an initialization instruction to perform initialization configuration; the initialization instruction includes a plurality of standardized parameters, which are input by a technician through the human-computer interaction layer; the secure and stable control device 102 monitors the data of the power system 104 to obtain a variety of monitoring data, and determines the states of the components in the power system 104 according to the variety of monitoring data and the initialization configuration; further, the secure and stable control device 102 obtains a fault identification result and an operation mode identification result according to the variety of monitoring data, the states of the components and the initialization configuration. When the fault identification result indicates that a fault exists, the secure and stable control device 102 determines a target control strategy according to the fault identification result, the operation mode identification result and the initialization configuration, and sends the target control strategy to the power system 104.

[0063] In an exemplary embodiment, as Figure 2 shown, a secure and stable control method for a power system based on standardized program configuration is provided. Taking the method applied to the secure and stable control device 102 in Figure 1 as an example for description, the secure and stable control device will be simply referred to as a stability control device in the following text, and includes the following steps S202 to step S210. Among them:

[0064] Step S202, in response to an initialization instruction, perform initialization configuration.

[0065] Among them, the initialization instruction includes a plurality of standardized parameters. Among them, the standardized parameters can be parameters in the secure and stable control system that need to be uniformly set by technicians according to certain standards and specifications, and can be the judgment basis for the stability control device to make decisions. Among them, the initialization configuration can be to configure the secure and stable control according to the standardized parameters, including hardware components, software settings, interface standards, etc., to ensure that all similar devices have consistent performance when in use.

[0066] Optionally, the stability control device responds to the initialization instruction and performs initialization configuration according to the standardized parameters in the initialization instruction.

[0067] Step S204: Monitor the data of the power system to obtain various monitoring data.

[0068] Among them, the monitoring data can be various parameters involved in the operation of the power system, such as electrical quantities, switch quantities, and remote data acquisition information. Among them, the electrical quantity is a continuously changing analog signal reflecting the operation state of the power system; the switch quantity is a discrete signal reflecting the equipment state, usually only having two states of "0" and "1" (corresponding to "switching off / closing", "open / closed", etc.); the remote data acquisition information can be the data uploaded to the dispatching center through the data acquisition and monitoring system, remote terminal unit or intelligent terminal, covering electrical quantities and switch quantities, and extended to other information.

[0069] Optionally, the stability control device monitors the data of the power system to obtain various monitoring data, so as to comprehensively master the operation situation of the power system and provide a basis for subsequent safe and stable control.

[0070] Step S206: Determine the states of each component in the power system according to various monitoring data and the initial configuration.

[0071] Among them, the component can be the basic equipment or functional unit that constitutes the power grid, and the state of the component reflects the operating conditions, health degree or control logic of the component. Components can be divided into primary equipment (directly participating in the production, transmission and distribution of electric energy) and secondary equipment (controlling, protecting and monitoring primary equipment). Primary equipment includes power generation equipment, transformers, transmission equipment, switchgear, etc., and secondary equipment includes protection devices, measurement and control devices, communication equipment, etc.

[0072] Optionally, the stability control device determines the monitoring data related to each component of the power system from various monitoring data, and determines the states of each component in the power system by comparing and analyzing the monitoring data related to each component with the state judgment basis of each component in the initial configuration.

[0073] Step S208: Obtain the fault identification result and the operation mode identification result according to various monitoring data, the states of each component and the initial configuration.

[0074] Among them, the fault identification result can be the judgment result of whether there is a fault in the power system, including two results of having a fault and not having a fault.

[0075] Among them, the operation mode can be the operation situation of the power system, including normal mode, accident mode and emergency mode.

[0076] Optionally, the stability control device compares and analyzes various monitoring data and the states of each component with the fault judgment basis in the initialization configuration to obtain a fault recognition result, and compares and analyzes various monitoring data and the states of each component with the operation mode judgment basis in the initialization configuration to obtain an operation mode recognition result.

[0077] It should be noted that, to obtain the judgment result of a fault, the fault judgment basis in the initialization configuration includes component tripping, PT / CT disconnection, DC blocking / power rapid drop, new energy grid disconnection, etc. In addition, the startup condition for the fault determination of the security and stability control system can be that the monitoring data meets any one of current mutation, power mutation, overcurrent / overpower, frequency increase / decrease, voltage increase / decrease, digital input, and remote command.

[0078] Step S210, when the fault recognition result indicates the existence of a fault, determine the target control strategy according to the fault recognition result, the operation mode recognition result, and the initialization configuration, and send the target control strategy to the power system.

[0079] Among them, the target control strategy can be a set of control instructions dynamically generated by the control system according to the real-time operation state of the power grid and preset rules, and is used to eliminate or alleviate the unstable factors of the power grid.

[0080] Optionally, when the fault recognition result indicates the existence of a fault, the stability control device obtains a variety of preset strategies from the initialization fault configuration, matches the fault recognition result and the operation mode recognition result with the various strategies, determines the strategy that matches both the fault recognition result and the operation mode recognition result as the target control strategy, and sends the target control strategy to the power system to maintain the safe and stable operation of the power system.

[0081] In the above-mentioned security and stability control method for a power system based on standardized program configuration, the method performs initialization configuration in response to an initialization instruction. The initialization instruction includes multiple standardized parameters, so that the configuration of the security and stability control system of the power system is completed based on multiple standardized parameters. Monitor the data of the power system to obtain various monitoring data to comprehensively understand the operation of the power system. Further, according to the various monitoring data and the initialization configuration, determine the states of each component in the power system, and according to the various monitoring data, the states of each component, and the initialization configuration, obtain the fault recognition result and the operation mode recognition result, so as to determine whether there are unstable factors in the power system. When the fault recognition result indicates the existence of a fault, determine the target control strategy according to the fault recognition result, the operation mode recognition result, and the initialization configuration, and send the target control strategy to the power system. The entire process of the security and stability control system from monitoring to determining the target control strategy is completed based on multiple standardized parameters of the initialization configuration, thereby improving the standardization degree of the security and stability control of the power system.

[0082] In an exemplary embodiment, before performing initialization configuration in response to the initialization instruction, step S202 further includes:

[0083] Obtain fixed value configuration and enabling configuration of multiple standardized parameters of a safety and stability control system; and generate initialization instructions according to the fixed value configuration and enabling configuration.

[0084] The fixed value configuration can refer to the threshold parameters pre-set in the system operation or control strategy, which are used to determine when to trigger the control action. These parameters are usually based on the physical characteristics of the power grid, safety limits or protection logic settings, and need to be determined through simulation calculations and regulations.

[0085] The enabling configuration may refer to the switch state of a control function or strategy, which determines whether a certain value or control logic is activated. It is usually expressed as a Boolean value (0 / 1) or an enumeration value (such as "on / off").

[0086] Optionally, the stabilization control device obtains constant value configurations for multiple standardized parameters of the safety and stability control system, such as equipment parameter constants, strategy constants, slave constants, and soft pressure plate settings, and obtains enabling configurations, such as device parameters, communication parameters, description parameters, and test constant value settings; based on the constant value configuration and enabling configuration, an initialization instruction is generated so that the stabilization control device can quickly enter a ready state according to the initialization instruction when starting, restarting, or switching operating modes.

[0087] In this embodiment, in the power system safety and stability control system, initialization instructions are generated through the fixed value configuration and enable configuration of standardized parameters to achieve precise, flexible and standardized operation of the safety and stability system, further improving the degree of standardization.

[0088] In an exemplary embodiment, after obtaining the fault identification result and the operation mode identification result according to the various monitoring data, the status of each component and the initialization configuration, the method further includes:

[0089] Determine the analog and switch quantities of the power system based on monitoring data; generate a position change report based on component status; generate an operation report based on the operation mode identification results; display analog quantities, switch quantities, position change reports and operation reports.

[0090] Among them, the analog quantity can be a continuously changing physical quantity in the power system, which is usually converted into an electrical signal by a sensor and then collected to reflect the real-time operating conditions of the system.

[0091] Among them, the switch quantity can be a signal representing the discrete state or event of the device, with only two states (such as 0 / 1, open / closed), which is used to describe the device action or abnormality.

[0092] Among them, the displacement report can be a document recording the changes in the device status (displacement), including information such as time stamps, device names, original status, and new status, and is used to track operation or fault events.

[0093] Among them, the operation report can be a summary and analysis of the overall operation status of the power system, generated based on analog quantities, digital quantities, and operation mode recognition results, and reflecting the safety, economy, and stability levels of the power grid.

[0094] Optionally, the stability control device determines the analog quantities that belong to the continuous changes of the power system and the digital quantities representing the discrete status or events of the devices from various monitoring data. The stability control device generates a displacement report according to the changes in the component status and a preset report template, and generates an operation report according to the operation mode recognition result and the preset report template. The analog quantities, digital quantities, displacement report, and operation report are displayed through the interface of the human-machine interaction layer of the stability control device, enabling technicians to intuitively and timely understand all aspects of the power system.

[0095] In this embodiment, continuous monitoring of analog quantities can promptly detect abnormalities such as overload, voltage dips, and frequency fluctuations, avoiding equipment damage or system collapse. Quick capture of digital quantities can immediately trigger an alarm, helping operation and maintenance personnel locate the fault point. The displacement report provides an operation record with a time stamp, meeting the audit requirements of the power safety regulations. The operation report summarizes the load of the entire network, voltage qualification rate, device commissioning and withdrawal status, etc., helping dispatchers optimize the power generation plan and adjust the power flow distribution.

[0096] In an exemplary embodiment, after determining the target control strategy according to the fault recognition result, operation mode recognition result, and initialization configuration, it further includes:

[0097] Generating an action report according to the target control strategy; and obtaining the policy execution feedback from the power system to obtain the policy status quantity; displaying the action report and the policy status quantity.

[0098] Among them, the action report can be a detailed record of specific operation instructions or actions generated based on the target control strategy, and the content can include the type of action executed, specific parameters of the action, execution event of the action, execution entity, etc.

[0099] Among them, the policy status quantity can be the execution situation of the target policy, including the progress of the target policy execution, the response of the power system after execution, and other contents.

[0100] Optionally, the stability control device generates an action report according to the content corresponding to the target control strategy and a preset template, and obtains the policy execution feedback from the power system for sorting to obtain the policy status quantity, and displays the action report and the policy status quantity through the human-machine interaction interface of the stability control device.

[0101] In this embodiment, by generating and displaying an action report and a policy status quantity, technicians can master the detailed content of the target control policy issued by the stability control device and timely understand the progress of the policy, so as to make corresponding adjustments.

[0102] In an exemplary embodiment, the security and stability control method for a power system based on standardized program configuration described in the above embodiment further includes:

[0103] Based on multiple monitoring data, obtain the device operation status recognition result; generate a self-check report according to the device operation status recognition result; display the self-check report.

[0104] Among them, the self-check report can be a standardized report, reflecting the health status and operation compliance of internal modules and external components of the device, and is used for operation and maintenance monitoring and fault troubleshooting.

[0105] Optionally, the stability control device analyzes according to multiple monitoring data and the device operation status recognition logic preset in the initialization configuration to obtain the device operation recognition result. Further, according to the device operation status recognition result and a preset template, a self-check report is generated, and the self-check report is displayed through the interface of the human-computer interaction layer.

[0106] In this embodiment, the data-based analysis method improves the accuracy of recognition and avoids the subjectivity and errors of manual judgment. The stability control device automatically generates a self-check report according to the device operation status recognition result and a preset template, which not only reduces the workload of manual operation, but also improves the report generation efficiency, ensuring the standardization and consistency of the report. Displaying the self-check report through the human-computer interaction interface enables operation and maintenance personnel to timely understand the system status, quickly respond to potential problems, and improve the reliability and security of the system.

[0107] In an exemplary embodiment, in step S210, determining the target control policy according to the fault recognition result, the operation mode recognition result, and the initialization configuration, and sending the target control policy to the power system includes:

[0108] Query the policy table preset in the initialization configuration according to the fault recognition result and the operation mode recognition result to obtain the target control policy; generate a matrix command or a capacity command according to the target control policy; send the matrix command or the capacity command to the power system.

[0109] Among them, the policy table can be a correlation table between a preset variety of policies, a variety of fault recognition results, and a variety of operation mode recognition results, and is set by technicians according to past maintenance experience.

[0110] Among them, the matrix command can be a discrete control instruction based on logical relationships, directly controlling devices in the power system (such as circuit breakers, relays, etc.) through "switching quantity operations", usually represented in binary (0 / 1) or Boolean values (True / False).

[0111] Among them, the capacity command can be a control instruction based on continuous quantity regulation, achieving dynamic stability control by adjusting the operating parameters of devices in the power system (such as power, voltage, frequency, etc.).

[0112] Optionally, the stability control device queries the preset strategy table in the initialization configuration according to the fault identification result and the operation mode identification result, and determines the target control strategy that matches both the fault identification result and the operation mode identification result; further, the stability control device generates a matrix command or a capacity command according to the target control strategy, and sends the matrix command or the capacity command to the power system.

[0113] In this embodiment, by combining dual criteria of the fault type (such as line tripping, DC blocking) and the operation mode (such as island operation, large load mode), the optimal control strategy is screened from the preset strategy table to avoid misoperation or refusal to operate caused by a single criterion.

[0114] In an exemplary embodiment, as Figure 3 shown, and as Figure 4 shown, a standardized program configuration method for a power system security and stability control device is provided, including:

[0115] Step 1: According to the established security and stability control strategy requirements, combined with the device access interval information, clarify the access analog quantity and switching quantity information.

[0118] Step 4: Configure the device settings at the human-machine interaction level. Configure the device parameters, communication parameters, description parameters, and test setting values of the device setting interface to implement the settings and enabling of each module at the internal standardized program configuration level.

[0119] Step 5: Configure the setting value at the human-machine interaction level. Based on the setting result of Step 4, further configure the setting value of each module at the internal standardized program configuration level to complete the implementation of the established security and stability control strategy device.

[0120] Step 6: Configure the measurement module at the internal standardized program configuration level. According to the requirements of the established security and stability control strategy, configure the electrical quantities, switch quantities, or remote data acquisition information in the measurement module.

[0121] Step 7: Configure the component status discrimination module at the internal standardized program configuration level. Configure the interval access of the component status discrimination module and enable the electrical quantity and switch quantity connection / disconnection criteria to realize the discrimination of component connection / disconnection information.

[0122] Step 8: Configure the device startup module at the internal standardized program configuration level. Configure the device startup module to monitor the interval information and enable the startup logic criteria such as current mutation, power mutation, overcurrent / overpower, frequency increase / decrease, voltage increase / decrease, switch quantity, and remote command. Combine the measurement module and the component status discrimination results to realize the device startup discrimination.

[0123] Step 9: Configure the fault discrimination module at the internal standardized program configuration level. Configure the fault discrimination module to monitor the interval information and enable the criteria such as component tripping, PT / CT disconnection, DC blocking / power rapid drop, and new energy grid disconnection. Combine the measurement module and the component status discrimination results to realize the device fault discrimination.

[0124] Step 10: Configure the operation mode discrimination module at the internal standardized program configuration level. Configure the operation mode discrimination module to monitor the information and enable the criteria such as normal mode, accident mode, and special mode. Combine the measurement module, the component status discrimination results, and the fault discrimination results to realize the device operation mode discrimination.

[0125] Step 11: Configure the strategy matching module at the internal standardized program configuration level. Configure the strategy matching module to access the information and enable the specific static stability criteria, transient stability criteria, and thermal stability criteria of the established strategy requirements to realize the configuration of the established stability control strategy of the device.

[0126] Step 12: Configure the command export module at the internal standardized program configuration level. Configure the strategy command export information according to the established strategy requirements, and execute the local export or send the command to the remote substation for execution.

[0127] In this embodiment, the configuration of the stability control standardized program is divided into two parts: the human-computer interaction level and the internal standardized program configuration level. By setting and calling the functions of each standard module in the standardized program configuration level through the human-computer interaction level, the customized development process of the stability control device program is simplified, and the standardized program configuration of various stability control strategies is realized.
