[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] According to an embodiment of the present invention, an embodiment of a data interaction control method for a hydroelectric generating unit controller with integrated logical security constraints is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0044] In this embodiment, a data interaction control method for a hydroelectric generating unit controller with integrated logical security constraints is provided. Figure 1 It is a flowchart of a data interaction control method for a hydroelectric generating unit controller with integrated logical security constraints according to an embodiment of the present invention. As Figure 1 shown, the process includes the following steps:

[0045] Step S101, obtain the real-time monitoring data of each device of the hydroelectric generating unit.

[0046] In an embodiment of the present invention, the real-time monitoring data of all associated devices at the hydroelectric power station site is obtained, and the monitoring data is the data collected by the controller, including various information such as switch positions, device states, temperatures, pressures, and liquid levels.

[0047] Step S102, screen out the associated information related to the safe operation of the device from the monitoring data, and apply the associated information to the device operations and logical interlocks related to device safety.

[0048] In the embodiments of the present invention, the monitoring data is analyzed. There are many devices at the hydropower station site, and each device has its own unique safety logic. When the devices are operating, the device states may affect each other. When it is necessary to operate a certain device, the states of related devices must be considered to ensure the safety of the devices and personnel. Based on the acquisition of real-time monitoring data, the operating conditions of all related systems are analyzed in real time. For different devices, the operating conditions refer to the switch positions of the devices, the running or stopping of the devices, the pressure levels of containers or pipelines, etc.

[0049] Using the safety control model, the relevant device information is analyzed at the station control level, and the associated information related to the safe operation of the devices is automatically screened out from the monitoring data as useful information and applied to the device operations and logical interlocks related to device safety. The logical interlock is used to judge the control logic and interlock conditions of the devices. The content of the useful information includes but is not limited to the relevant control authorities, device digital / analog quantities, dispatching instructions, and emergency operations, etc.

[0050] Among them, the control logic means that when performing a certain safety operation, a certain operation sequence and rules must be followed. The interlock condition means that the current state of a certain device is used as the operation condition for another device.

[0051] In step S103, when performing device operations related to the devices, the safety control strategy integrating logical safety constraints is used to share the safety constraint conditions, control interlock conditions, and device control authorities to realize data interaction between different controllers of the hydropower unit.

[0052] In the embodiments of the present invention, when performing device operations related to the actual devices, except for necessary emergency operations, comprehensive control constraint conditions including local operation permissions must be considered to ensure the safe operation of the devices. By adopting reliable data interaction technology, at the overall system level, the safety control strategy integrating logical safety constraints is used to share the safety constraint conditions, control interlock conditions, and device control authorities to realize data interaction between different controllers.

[0053] Specifically, the constraint condition means that a safety logic or constraint condition is built in a certain controller and shared with other controllers through reliable data interaction technology without repeating the same logic in each controller. The control interlock condition means the interlock condition set for the control operation instruction, and the instruction is not allowed to be issued when it is not satisfied to ensure the safety of the device.

[0054] The hydropower unit controller data interaction control method provided in this embodiment integrates logical safety constraints. By monitoring the data of each device in the hydropower unit, the associated information related to the equipment operation safety in the monitoring data is applied to the equipment operation and logical interlocking related to the equipment safety. The safety control strategy integrating logical safety constraints is used to realize data interaction between the controllers of the hydropower unit, strengthen the control interlocking capability at the system level and between devices, maximize the factors related to equipment safety, improve the operation safety and protection of each equipment in the hydropower unit, and improve the reliability of the power system.

[0055] In this embodiment, a method for data interaction control of a hydropower unit controller integrating logical safety constraints is provided, and the process includes the following steps:

[0056] Step S201, obtaining real-time monitoring data of each device of the hydropower unit.

[0057] For details, please see Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0058] Step S202, filtering out associated information related to equipment operation safety from the monitoring data, and applying the associated information to equipment operations and logical interlocks related to equipment safety.

[0059] For details, please see Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0060] Step S203, when configuring the security control policy integrating the logical security constraints, a trusted mark is preset.

[0061] Step S204: when the trusted tag changes, reconfigure the security control policy integrating the logical security constraints.

[0062] Step S205: When the trusted tag has not changed, a security control strategy of the fusion logic security constraint with a preset configuration is adopted.

[0063] In the embodiment of the present invention, when configuring the security control policy of the fusion logic security constraint, it is necessary to preset a suitable trusted tag. The trusted tag is preset by logic according to needs, and the trusted tag will be affected by factors such as the permission switching, state change, device failure, and network communication of the relevant equipment. When the trusted tag changes, the security control policy of the fusion logic security constraint must be reconfigured to avoid security risks caused by untrusted data or control instructions. When the trusted tag has not changed, the data is credible, and the optimized control of interlocking action priority, safety locking and other operations can be implemented according to the preset security control of the fusion logic security constraint, thereby achieving reliable control.

[0064] Step S206: When performing device operations related to the device, share the safety constraint conditions, control interlock conditions, and device control authorities by using the safety control strategy that integrates logical safety constraints, so as to achieve data interaction between different controllers of the hydro-generating unit.

[0065] For details, please refer to Figure 1 Step S103 of the embodiment shown, which will not be elaborated here.

[0066] The data interaction control method for the hydro-generating unit controller that integrates logical safety constraints provided in this embodiment reconfigures the safety control strategy that integrates logical safety constraints when the trusted tag changes by presetting the trusted tag, avoiding potential safety hazards caused by untrusted data or control instructions, and adopting the preset safety control strategy that integrates logical safety constraints when the trusted tag does not change, so as to achieve reliable control.

[0067] This embodiment also provides a data interaction control system for the hydro-generating unit controller that integrates logical safety constraints. The system includes: a data provider, a data requirer, and a data usage side.

[0068] Among them, the data provider is used to provide real-time monitoring data of each device of the hydro-generating unit. The monitoring data includes switch position, device status, temperature, pressure, liquid level, etc.

[0069] The data requirer receives the associated information related to the safe operation of the device from the data provider. The information content includes but is not limited to relevant control authorities, device digital / analog quantities, dispatching instructions, and emergency operations, etc. Analyze the associated information and use it for device operation and logical interlock after analysis. Among them, the logical interlock is used to judge the control logic and interlock conditions of the device, and display them to the operation and maintenance personnel or other technical personnel in real time in the form of numerical values, texts, or graphics. Among them, the analysis result means that in order to improve the transmission rate, data is encapsulated at the sending end and then opened again at the data usage side to release the proper data type for the data usage side to use the data.

[0070] The data provider configures the safety control strategy that integrates logical safety constraints. When the data usage side performs device operations related to the device, it adopts reliable data interaction technology. From the overall system level, it shares the safety constraint conditions, control interlock conditions, and device control authorities by using the safety control strategy that integrates logical safety constraints, so as to achieve data interaction between different controllers.

[0071] The data interaction control system of the hydro-generator unit controller integrating logical security constraints provided by this embodiment provides real-time monitoring data of each device of the hydro-generator unit through the data provider. The data demander analyzes the associated information related to the operation safety of the device in the monitoring data, performs device operations and logical locking. The data user side utilizes the security control strategy of integrating logical security constraints configured by the data provider to achieve data interaction between different controllers of the hydro-generator unit, strengthen the control locking ability at the system level and between devices, maximize the device safety-related factors, improve the operation safety and protection of each device of the hydro-generator unit, and improve the reliability of the power system.

[0072] In some optional embodiments, when configuring the security control strategy of integrating logical security constraints, the data provider needs to preset appropriate trust marks. The trust marks are affected by factors such as the permission switching, status change, device failure, and network communication of related devices. Once the trust marks change, it is necessary to consider handling necessary strategies and reconfigure the security control strategy of integrating logical security constraints to avoid potential safety hazards caused by untrusted data or control instructions. If the trust marks do not change and the data is trusted, the security control strategy of integrating logical security constraints configured by default can be adopted to achieve optimized control with priority of interlocking actions, security locking, etc., so as to achieve reliable control.

[0073] By presetting trust marks by the data provider and reconfiguring the security control strategy of integrating logical security constraints when the trust marks change, potential safety hazards caused by untrusted data or control instructions are avoided, and the security control strategy of integrating logical security constraints configured by default is adopted when the trust marks do not change, so as to achieve reliable control.

[0074] In some optional embodiments, the data user side obtains, analyzes, and uses the required data in accordance with the principle of the demander's responsibility, verifies the trust marks, and verifies the consistency between the obtained monitoring data and the monitoring data provided by the data provider to achieve real-time status monitoring of hydro-related devices.

[0075] Specifically, special flag bits can be set for verification. After parsing the received data, if the corresponding flag bits do not meet the preset conditions, they are marked as untrusted, the untrusted data is discarded, and the data is required to be resent.

[0076] By the data user side verifying the trust marks and the consistency between the monitoring data and the monitoring data provided by the data provider to ensure the reliability of the data, when the data is untrusted, the data is discarded and the data is required to be resent to ensure the trustworthiness of the data.

[0077] In some optional embodiments, the data of the data user side is also used to execute the operation instructions of the corresponding device according to the security constraint conditions shared by using the security control strategy of integrating logical security constraints.

[0078] Specifically, the data usage side executes operation instructions including single device operation, process control, etc. based on the comprehensive control constraint information including local operation permissions that it has learned, which not only ensures the real-time interaction of control data but also ensures the reliability of the control of the controlled device.

[0079] Among them, the control constraint information is diverse. For example, when a certain pump needs to be started, the information that the controller needs to know includes: (1) Whether the valves before and after the pump have been opened? (2) Whether the control loop of the pump itself is normal? (3) Whether the control permission of the pump allows operation? (4) Whether the pump has a prohibited operation mark.

[0080] By corresponding to execute the remote operation instruction control of the hydro-generating unit and related equipment according to the security constraint conditions shared by the security control strategy that utilizes the fusion logic security constraint, it provides technical guarantee for the safe operation of the equipment.

[0081] In some optional implementation manners, the data provider is also used to perform data configuration and encapsulation on the monitoring data and configure the data requester.

[0082] Specifically, the network data variable that can configure the data evaluation strategy and security mark is the medium for system data exchange. Necessary data for the security control model is defined and generated in each LCU (Local Control Unit), and the data evaluation strategy and security mark are set according to the principle that the provider is responsible, and then data transmission is carried out through the Ethernet that can be redundantly configured.

[0083] In the transmission configuration, the data provider performs data configuration and encapsulation and configures the destination network node (data requester). Data configuration means that the data can be packaged and transmitted, allowing different types of data to be included, such as digital quantities, analog quantities, and even more composite data types.

[0084] By the data provider performing data configuration and encapsulation on the monitoring data and configuring the data requester, it realizes the packaged transmission of the data and configures the destination network node.

[0085] The data providing side realizes data acquisition, standardized use, integration and sharing of network variables, etc. through the necessary logical security constraint control conditions set by the system, and sets the data evaluation strategy and security mark according to the principle that the provider is responsible.

[0086] The data interaction network adopts an Ethernet that can be redundantly configured and supports a flexible topology structure to realize network security verification, data transmission, quality management, etc.

[0087] On the data - using side, in accordance with the principle of the demander being responsible, judgments, analyses, and decisions are made on the acquisition, analysis, and standardized use of the required shared data, realizing real - time status monitoring of hydropower - related equipment, ensuring the security, reliability, and credibility of the control data used, and executing operation instructions such as single - device operation and process control based on the comprehensive control constraint information obtained, including local operation permits, so as to maximize the safety of the controlled equipment and efficient operation management.

[0088] By setting appropriate logical security constraint control conditions among system controllers, the real - time status of all hydropower - unit - related equipment is monitored, the operation conditions of all related systems and equipment are analyzed, and the issuance of hydropower - equipment control instructions is placed under reliable, safe, and credible control factors, maximizing the safety of the controlled equipment and the safety of operation and maintenance personnel.

[0089] Necessary logical security constraints are set in the data interaction between LCU. Once it is necessary to manually or automatically operate a single device or sequence control logic, whether in normal or fault conditions, the safety status and control constraint conditions of the associated equipment should be preferentially judged. Only when reliable and credible safety operation control permits are obtained can remote control and on - site control of hydropower units and related equipment be executed, thus providing technical guarantees for the operation and safety of the equipment.

[0090] As Figure 2 shown, Figure 2 is a schematic diagram of control - information interaction. The operator station, engineer station, and server are connected through redundant Ethernet. Redundant Ethernet provides reliability. When one line fails, the other line can still ensure communication. The operator station, engineer station, and server conduct data interaction with each LCU. There are two switches, A and B, inside each LCU for data exchange. This control - information interaction technology is applied to the data - interaction control scenario of hydropower - unit controllers to realize the monitoring and control of on - site equipment.

[0091] As Figure 3 shown, Figure 3 is a schematic diagram of data - providing direction. Figure 3 In it, the data of device1 (address is 1) can be sent for device2 (address is 2) to use, the data of device2 (address is 2) can be sent for device1 (address is 1) to use, and the data of device3 (address is 3) can be sent for both device1 (address is 1) and devic2 (address is 2) to use.

[0092] As Figure 4 shown, Figure 4 is a schematic diagram of data - using direction. Figure 4The data of device2 (with address 2) and device3 (with address 3) can be sent to device1 (with address 1) for use simultaneously, and the data of device1 (with address 1) and device3 (with address 3) can be sent to device2 (with address 2) for use simultaneously.
