Description

Technical Field

[0001] This invention relates to an intelligent inspection method and device for safety control pressure plates, and in particular to an intelligent inspection method and device based on pressure plate activation and deactivation rules that can be programmed on-site, belonging to the field of power system safety and stability master station management technology. Background Technology

[0002] Monitoring of security control gates is a crucial aspect of security control device monitoring. Incorrect gate operation or erroneous activation can affect the device's strategic function judgment and the correctness of its actions. With the increasing number of power grid security control devices and the growing complexity of security control strategies, manual gate verification is extremely difficult and labor-intensive, necessitating intelligent and online methods for gate verification.

[0003] Currently, the safety control management master station has a function for inspecting pressure plates based on a set fixed benchmark value. It compares the current pressure plate status with the set benchmark value and issues an alarm when they are inconsistent. The pressure plate status depends on factors such as the power grid operating mode, line activation / deactivation status, and generator operating status. The benchmark value is not fixed; when the power grid operating conditions are adjusted, the pressure plate status should be adjusted accordingly. If the benchmark value is not adjusted in a timely manner, the inspection results will be inaccurate. The current pressure plate inspection function cannot adapt to situations where the pressure plate benchmark value needs dynamic adjustment. Therefore, a smart inspection method for safety control pressure plates that can dynamically update the pressure plate activation / deactivation benchmark value is needed, providing flexible and customizable pressure plate activation / deactivation rules to ensure the accuracy of inspection results and improve the operation and maintenance level of the stability control management master station. Summary of the Invention

[0004] The main objective of this invention is to overcome the shortcomings of the prior art and provide a method and device for intelligent inspection of security control pressure plates based on a programmable platform. It adopts visual programming to establish a rule base for the deployment and deployment of security control pressure plates, and associates the inputs in the rule base with the real-time measurement points of the security control management master station system. This enables dynamic updates of the benchmark value of the security control pressure plates at the time of inspection, ensuring the accuracy of the inspection results and identifying and warning of incorrect deployment of pressure plates.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A method for intelligent inspection of safety control pressure plates based on a programmable platform, comprising the following steps:

[0007] Step 1: Based on the programmable platform, build a logic rule base for the activation and deactivation of the security control pressure plate.

[0008] The programmable platform employs visual logic programming, supporting on-site logic configuration. It allows for the construction of execution logic based on arbitrary numerical inputs, supporting arithmetic, relational, and logical operations to achieve arbitrary combinations of conditions. The status of the safety control panel is related to conditions such as the power grid operation mode, line activation / deactivation status, unit operation status, and equipment operation status (normal operation, signal status, maintenance status, etc.). These conditions are logically configured to form a logic diagram describing the panel activation / deactivation rules, thus creating a rule base.

[0009] Step 2: The input quantities of the logic rule base and the measurement points of the real-time database of the security control management master station system are used to generate the security control pressure plate status baseline value.

[0010] Maintenance personnel access the real-time database of the security control management master station system through the programmable platform, associate the input quantities of the logic rule database with the measurement points of the real-time database of the security control master station system, obtain the real-time collected values ​​of each input in the current time of the pressure plate activation / deactivation rule logic diagram, and obtain the status baseline value of each security control pressure plate under the current conditions through logical calculation.

[0011] Step 3: Set the inspection cycle.

[0012] Manually set the inspection cycle for the safety control pressure plate.

[0013] Step 4: Intelligent inspection and alerts for abnormal results.

[0014] At the manually set inspection time, the security control management master station system issues a pressure plate inspection command, dynamically updates the security control pressure plate status benchmark value at the inspection time, compares the collected actual value of the security control pressure plate with the benchmark value, and issues an abnormal warning signal if the comparison result is inconsistent.

[0015] A smart inspection device for a security control pressure plate includes a security control management master station system and a programmable platform, wherein: the programmable platform establishes a logic rule library for the activation and deactivation of the security control pressure plate, and the input values ​​of the logic rule library are associated with the measurement points in the real-time library of the security control management master station system;

[0016] The security control management master station system generates the security control pressure plate status baseline value, issues inspection instructions according to the set inspection cycle, and issues a warning when abnormal results are found.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] Based on a programmable platform and employing visual graphical configuration programming, the logic diagram for the pressure plate activation / deactivation is intuitive and easy to understand, facilitating troubleshooting and modification. The pressure plate reference value can be dynamically updated according to changes in power grid operating conditions, ensuring the accuracy of inspection results.

[0019] The above content is only an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0023] This invention provides an intelligent inspection method for safety control pressure plates based on a programmable platform. A schematic diagram of the method is attached. Figure 3 As shown, the safety control management master station collects real-time power grid operation information, safety control device information, and unit start-up and shutdown information into a real-time database. Maintenance personnel establish a rule base on the programmable platform and associate the input values ​​of the rule base with the real-time database measurement points of the safety control management master station. They set inspection cycles, and at the inspection time, the safety control management master station issues an inspection command, compares the actual value of the safety control pressure plate with the reference value of the safety control pressure plate, and issues an anomaly alarm, thus achieving intelligent inspection. Specifically, this includes the following steps:

[0024] Step 1: Based on the programmable platform, build a logic rule base for the activation and deactivation of the security control pressure plate.

[0025] The programmable platform uses visual logic programming, as shown in the attached diagram. Figure 2 As shown, it supports the "Logic" field configuration function, supporting arithmetic operations, relational operations, and logical operations. The inputs to the logic diagram are conditions affecting the safety control board's status, such as the power grid operation mode, line on / off status, unit operation status, and equipment operation status (normal operation status, signal status, maintenance status, etc.). By logically configuring these conditions, the output is the safety control board's reference value. (Attached) Figure 1 The input is "Line 1 under maintenance", "Line 2 under maintenance", "Line 3 under maintenance", and "Line 4 under maintenance", with the operator "&". The output is "Special pressure plate activated" for the safety control device. This means that the special pressure plate of the safety control device is activated when all four lines (Line 1, 2, 3, and 4) are under maintenance. Visual graphical programming is used, making the activation and deactivation rules of the safety control pressure plate intuitive and easy to understand, facilitating troubleshooting and modification by maintenance personnel.

[0026] Step 2: Associate the input values ​​of the logic rule base with the measurement points of the real-time database of the security control management master station system to generate the security control pressure plate status baseline value.

[0027] Maintenance personnel access the real-time database of the security control management master station system through the programmable platform, associate the input quantities of the logic rule database with the measurement points of the real-time database of the security control master station system, obtain the real-time collected values ​​of each input in the current time of the pressure plate activation / deactivation rule logic diagram, and obtain the status baseline value of each security control pressure plate under the current conditions through logical calculation.

[0028] Step 3: Set the inspection cycle.

[0029] Set the inspection cycle for the security control pressure plate in the security control management master station system.

[0030] Step 4: Intelligent inspection and alerts for abnormal results.

[0031] At the manually set inspection time, the security control management master station system issues a pressure plate inspection command. The programmable platform rule base dynamically updates the security control pressure plate status benchmark value at the inspection time based on the collected values ​​provided by the security control management master station system, and compares the collected actual value of the security control pressure plate with the benchmark value. If the comparison result is inconsistent, an abnormal warning signal is issued.

[0032] Based on the same inventive concept, this invention also provides an intelligent inspection device for security control pressure plates, including a security control management master station system and a programmable platform. The intelligent inspection method for security control pressure plates implemented based on this device will not be described in detail here.

[0033] The innovation of this invention lies in its use of a programmable platform and visual graphical configuration programming. The logic diagram for the activation and deactivation of the pressure plate is intuitive and easy to understand, facilitating troubleshooting and modification. The pressure plate reference value can be dynamically updated according to changes in power grid operating conditions, ensuring the accuracy of inspection results and improving the operation and maintenance level of the safety control management master station.
