Description

Technical Field

[0001] This invention relates to a method and apparatus for automatically generating monitoring images of power plant and substation access channels, belonging to the field of power system technology. Background Technology

[0002] Currently, mainstream power dispatching and monitoring systems rely on manual drawing of substation monitoring screens for each station. With numerous substations existing in the field, the drawing process for each station requires a series of status data associations, checks, and verifications, specifically including information such as the substation's voltage level, region, protocol information, and duty access points. With the continuous integration of new energy stations, station upgrades and commissioning / decommissioning are frequent, necessitating manual modifications to the screens. Against the backdrop of the national push for intelligent information infrastructure construction, there is a need for a method that can automatically generate substation monitoring screens and support real-time online modifications, delegating the drawing work to computer programs. This would make the power system more intelligent and visualized, effectively reducing the workload for power operation monitoring and maintenance personnel. Summary of the Invention

[0042] Figure 5 This is a schematic diagram of the interaction architecture between the server and the client. Detailed Implementation

[0043] The present invention will be further described below with reference to specific embodiments. These embodiments are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0044] Figure 1 This is a flowchart illustrating a method for automatically generating monitoring screens in power system substations, according to an embodiment of the present invention. The method is executed on the server side, such as... Figure 1 As shown, the method includes at least:

[0045] Step 11: In response to the screen modification command sent by the client, calculate and generate updated monitoring screen strategy information, i.e., monitoring screen data information of the station channel, in combination with the basic parameter information of the channel plant, and send the updated monitoring screen strategy information to the client.

[0046] Screen modification commands, such as modifying the size of plant channel elements, modifying the screen background color, filtering plant channels, and other expandable commands.

[0047] Basic parameter information for power plants and substations includes: voltage level, power grid area, protocol type, number of protocols, on-duty channel, and backup channel.

[0048] The basic parameter information of the channel plant can be obtained by the server periodically from the database or real-time library (file library) or by listening to real-time messages generated by the real-time library. Since the basic information of the channel plant is obtained from the database or real-time library, rather than from the workstation where the current graphical browser is located, a lightweight client solution is provided.

[0049] In one implementation, based on the instruction to modify the size of the station channel elements, combined with the number of stations in the channel and the current screen size, and following a strategy of uniform layout in the visible area, the size of the channel elements and the coordinate information of each element are calculated, the cache configuration of the strategy information is updated, and the updated strategy information is sent to the client.

[0050] In another implementation, the background color of the screen is changed to the required color according to the instruction to modify the background color of the screen, while other layout strategy information remains unchanged. The cache configuration of the strategy information is updated, and the updated strategy information is sent to the client.

[0051] In another implementation, based on the instruction to display the plant channel, the plant channel that meets the requirements is selected, while other layout strategy information remains unchanged. The cache configuration of the strategy information is updated, and the updated strategy information is sent to the client.

[0052] Step 12: In response to the client's request for the current station channel status information, push the station channel duty status information to the client.

[0053] Channel status information request, including a unique ID that marks this request and channel ID information.

[0054] The server pushes duty status information to the client, including the channel ID and corresponding duty status information. Typically, on-duty channels are green, and off-duty channels are red; the colors can be configured as needed.

[0055] Specifically, after receiving a request from the client for the channel status information of the current screen station, the system matches each corresponding channel ID based on the channel status information cached at startup, and pushes the requested channel status to the client after serialization using protobuf according to the channel duty status information corresponding to the channel ID.

[0056] After the client sends the channel status request data to the server for the first time, the server continues to push channel status information to the client's page.

[0057] The channel status information is also obtained by the server periodically from the database or real-time library or by listening to real-time messages.

[0058] Figure 2 This is a flowchart illustrating a method for automatically generating monitoring screens in power system substations, according to another embodiment of the present invention. The method is executed on the client side, such as... Figure 2 As shown, the method includes at least:

[0059] Step 21: Receive the voice modification command for the screen, parse it into a screen modification command that the server can recognize, and send it to the server;

[0060] The voice commands for modifying the screen can be customized to conform to a specific format. For example, you can change the size of communication substation elements to 200*300, change the background color to white, and display substations with voltage levels below 500kV.

[0061] Parsing received voice commands for modifying the screen refers to converting the voice commands into instructions that the server can recognize and process. Specifically, the instructions can be parsed into instructions containing three dimensions: operation type, operation object, and attribute value, and then serialized using protobuf before being sent to the server. For example, "change the background color to white" can be parsed as operation type "modify", operation object "background color", and attribute value "white".

[0062] Step 22: Receive the updated monitoring screen policy information sent by the server, and redraw and generate the plant channel monitoring screen according to the updated monitoring screen policy information;

[0063] After the client receives the monitoring screen strategy information sent by the server, the client redraws the screen according to the strategy of evenly distributing the visible area and the coordinate information of each graphic element.

[0064] Step 23: Based on the duty status information of the plant and station channels pushed by the server, draw and generate duty status graph elements for each channel.

[0065] After the client draws the screen, it requests the channel status information of the current screen station from the server. After receiving the channel duty status information pushed by the server, the client draws the status information of the duty status graphic elements.

[0066] Figure 3 This is a structural diagram of a power system substation channel monitoring screen automatic generation device according to an embodiment of the present invention. The device is deployed on a client-side platform, such as... Figure 3 As shown, the device includes at least:

[0067] The voice recognition device is configured to receive voice commands for modifying the screen, parse them into screen modification commands that can be recognized by the server, and send them to the server.

[0068] The graphical browser is configured to receive updated monitoring screen policy information sent by the server, redraw and generate monitoring screens for the plant and station channels based on the updated monitoring screen policy information, and draw and generate duty status graphs for each channel based on the duty status information pushed by the server.

[0069] Among them, speech recognition devices refer to devices that convert speech to text, such as iFlytek's speech service and devices.

[0070] Power grid maintenance personnel issue commands to automatically modify the screen through a voice recognition device. The client calls the voice recognition interface to obtain the command content, parses the qualified voice content, and sends it to the server.

[0071] By converting speech into command information using a speech recognition device and sending the generated page information to the server in real time, the problem of traditional methods that cannot modify policy information in real time or generate policy information through unfriendly parameter configuration can be solved.

[0072] Graphical browsers include C / S or B / S graphical browsers of mainstream power dispatching and monitoring systems, used to draw channel elements, channel status, etc.

[0073] Figure 4 This is a structural diagram of a power system substation channel monitoring screen automatic generation device according to another embodiment of the present invention. The device is deployed on a server, such as... Figure 3 As shown, the device includes at least:

[0074] The plant channel screen generation module is configured to respond to screen modification commands sent by the client, calculate and generate updated monitoring screen strategy information in conjunction with the basic parameter information of the plant channel, and send the updated monitoring screen strategy information to the client.

[0075] The channel status push module is configured to push the station channel's duty status information to the client in response to the client's request for the current station's channel status information.

[0076] The substation channel display generation module acquires channel parameters and status data in real time and listens for client requests. During initialization, the module retrieves and caches substation channel parameter information, channel status, voltage level of the substation, its grid region, protocol information, etc., from the real-time / historical database.

[0077] When the server receives a screen modification instruction request from the client, it processes the instruction according to the operation type, operation object, and attributes, calculates the graphic element coordinate information and corresponding key-value pair attributes (including background color, filter station channels, etc.) and caches them, generates modification strategy information, and sends it to the client.

[0078] In one example, the plant / station passageway image generation module, based on the instruction to modify the size of the plant / station passageway elements, combined with the number of plant / station passageways and the current image size, calculates the size of the passageway elements and the coordinate information of each element according to a strategy of uniform layout within the visible area. It then updates the cache configuration of the strategy information and sends the updated strategy information to the client. Here, "layout" refers to the use of passageway elements and shift status elements for representation.

[0079] In another example, the plant channel screen generation module, based on the instruction to modify the screen background color, changes the background color of the screen to the required color, while keeping other layout strategy information unchanged, updates the cache configuration of the strategy information, and sends the updated strategy information to the client.

[0080] In another example, the plant channel image generation module filters out the plant channels that meet the requirements according to the instructions for filtering plant channels, keeps other layout strategy information unchanged, updates the cache configuration of strategy information, and sends the updated strategy information to the client.

[0081] Figure 5 This diagram illustrates the server-client interaction architecture for automatically generating monitoring images of power system substations. Figure 5 As shown, the process for automatically generating monitoring screens in power system substations includes:

[0082] Power grid maintenance personnel issue commands to automatically modify the screen through the client's voice recognition device, and the voice recognition device automatically parses the voice command request into a command containing the operation type, operation object and attribute value and sends it to the server.

[0083] After receiving the screen modification instruction, the server calculates and generates monitoring screen policy information through the plant channel screen generation module, and sends the generated monitoring screen policy information to the client.

[0084] After receiving the monitoring screen policy information sent by the server, the client uses a graphical browser to redraw and generate the plant channel monitoring screen according to the received monitoring screen policy information.

[0085] After the client draws the monitoring screen, it requests the channel status information of the current plant from the server.

[0086] After receiving the channel status information request, the server pushes the channel's duty status information to the client through the channel status push module;

[0087] The graphical browser in the client draws and generates duty status graphics for each passage based on the duty status information of the plant passage pushed by the server.

[0088] Example 1:

[0089] When a client issues the command "Modify the size of communication station elements to 200*300" via a voice recognition device, the client page automatically parses the voice request into an operation type of "modify", an operation object of "element size", and an attribute value of "200*300". Upon receiving the modification command, the server modifies the length and width information of the elements, re-lays the layout according to the current page size, regenerates the coordinate information of each element according to a uniform arrangement rule, updates the policy information cache, and then sends all the modified policy information in the cache to the client. The client page then redraws and displays the new policy information. The front-end channel status push service pushes the obtained channel status to the front end to display the channel's operating status: on-duty channels are green, and off-duty channels are red.

[0090] Example 2:

[0091] When a client issues a command to "change the background color to white" via a voice recognition device, the client page automatically parses the voice request into an operation type of "modify," an operation object of "background color," and an attribute value of "white." Upon receiving the modification command, the server changes the page's background color to white, leaving other layout strategy information unchanged. It then updates the cached configuration of the strategy information and sends all cached configuration information to the client. The client page then redraws and displays the page based on the new configuration information. The front-end channel status push service pushes the channel's operational status to the front end based on the channel status obtained from the real-time database: on-duty channels are displayed in green, and off-duty channels in red.

[0092] Example 3:

[0093] When a client issues the command "Display channels and substations with voltage levels below 500kV" via a voice recognition device, the client page automatically parses the voice request into an operation type of "filtering," an operation object of "channel / substation voltage level," and an attribute value of "less than 500kV." Upon receiving the modification command, the server will only filter channels that meet the filtering criteria, keeping other layout strategy information unchanged, updating the cached configuration of the strategy information, and then sending all cached configuration information to the client. The graphical browser redraws and displays the information based on the new configuration. The front-end channel status push module pushes the channel status obtained from the real-time database to the front end to display the channel's operating status: on-duty channels are green, and off-duty channels are red.

[0094] This invention can be widely applied to power dispatching and monitoring systems such as OPEN3000, OPEN3200, D5000, D5200, and the new generation power dispatching control support system. It can effectively solve the problem of manually drawing channels and associating historical data one by one in scenarios such as power system station-end transformation, plant commissioning and decommissioning, and new system construction. It frees operation and maintenance personnel from the tedious drawing and verification work, which is conducive to quickly locating channel problems, improving the efficiency and level of power grid operation, and thus obtaining the greatest safety benefits.
