A network method, apparatus, equipment, and storage medium for energy metering in power plants.

Abstract

This application discloses a networking method, apparatus, equipment, and storage medium for energy metering in a power plant. The method includes dividing all metering devices in the power plant into multiple communication blocks based on metering area and multiple communication chains based on metering object. Each communication block contains multiple metering devices, and each communication chain contains multiple metering devices; that is, the same metering device is simultaneously located in one communication block and one communication chain. The method monitors for anomalies in the current metering device by performing dual monitoring of the communication chain and communication block where the current metering device is located at preset intervals. This application enables the metering devices in the power plant to have a self-judgment function by performing block determination and chain determination separately for the same metering device, and determining a misjudgment when the results of the two determinations are different. This eliminates misjudgments at the device level.

Description

Technical Field

[0001] This application relates to the field of energy metering equipment technology, and in particular to a network method, device, equipment and storage medium for energy metering in power plants. Background Technology

[0002] Smart meters are one of the fundamental data acquisition devices in smart grids (especially smart distribution networks). They undertake the tasks of collecting, measuring, and transmitting raw electrical energy data, forming the basis for information integration, analysis, optimization, and presentation. In addition to the basic electricity metering functions of traditional meters, smart meters, to adapt to smart grids and new energy sources, also possess intelligent functions such as bidirectional multi-rate metering, user-end control, bidirectional data communication with multiple data transmission modes, and anti-theft features. Advanced metering systems and automatic meter reading systems built upon smart meters provide users with more detailed electricity consumption information, enabling them to better manage their electricity consumption and achieve goals such as saving on electricity bills and reducing greenhouse gas emissions. Electricity retailers can flexibly set time-of-use pricing based on user needs, promoting reform of the electricity market pricing system. Distribution companies can more quickly detect faults and respond promptly to strengthen power network control and management.

[0003] Currently, there are various networking methods for metering equipment in power plants, such as radial, ring, multi-circuit, and grid-based systems. As long as theoretically no short circuits or open circuits occur, any networking connection method can be implemented, giving metering equipment networking a high degree of flexibility. However, the acquisition systems formed by the aforementioned networking methods lack dual or multiple verification functions. When abnormal data or errors occur in the energy metering process, manual on-site confirmation is required. Furthermore, due to the high degree of flexibility in network link connections, the stability of each link in the network varies, making it easy for the network to misdiagnose faults in the metering equipment. Summary of the Invention

[0004] The main objective of this application is to provide a networking method, device, equipment, and storage medium for energy metering in power plants, in order to solve the problem that existing networking links are prone to misjudging faults in metering equipment.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0016] Determine whether all second measurement parameters are within the preset range; if not, determine that the current measurement device is malfunctioning.

[0017] As a further improvement to this application, after determining whether all second measurement parameters are within the preset range, the process includes:

[0018] If so, it is determined that the current metering device is located in the communication chain or communication block where the misjudgment operation occurred;

[0019] Locate the communication chain where the current metering device is located, and obtain the third metering parameters of other metering devices in the current communication chain;

[0020] Determine whether all third measurement parameters are within the preset range. If yes, determine that the current communication chain is abnormal; otherwise, cancel the misjudgment operation and determine that the current measurement device is abnormal.

[0021] As a further improvement to this application, if a misjudgment operation is determined to have occurred in the communication chain or communication block where the current metering device is located, then the following steps are taken:

[0022] Locate the communication block where the current metering device is located, and obtain the fourth metering parameters of other metering devices in the current communication block;

[0023] Determine whether all fourth measurement parameters are within the preset range. If yes, determine that the current communication block is abnormal; otherwise, cancel the misjudgment operation and determine that the current measurement device is abnormal.

[0024] As a further improvement to this application, the three-dimensional layout is divided into at least two measurement regions using a first preset strategy, including:

[0025] Obtain the building information of the power station and define the building information as the three-dimensional layout;

[0026] The structural features of the building information are obtained, and the power station is divided into at least two power station sub-rooms according to the structural features. Each power station sub-room is defined as a metering area.

[0027] A first relay station is established in the current metering area. The first relay station is connected to each metering device in the current metering area to form a communication block of the current metering area.

[0028] As a further improvement to this application, the metering objects of each metering device are acquired and the metering devices of the same metering object are connected to each other by a third preset strategy to form at least two communication chains, each communication chain being connected to a gateway device, including:

[0029] Obtain the second position information of the measuring devices belonging to the same measuring object in the three-dimensional layout;

[0030] Based on each second location information, each metering device of the same metering object is sequentially connected using the shortest connection strategy to form a metering device chain;

[0031] A second transfer station is set up at the beginning or end of the metering equipment chain. The second transfer station is connected to the current metering equipment chain to form a communication chain.

[0032] As a further improvement of this application, a second transfer station is established at the beginning or end of the metering device chain. The second transfer station is communicatively connected to the current metering device chain to form a communication chain, which then includes:

[0033] Connect all first relay stations and all second relay stations to the server for communication.

[0034] The server monitors the first metering parameter of the current metering device at preset intervals through one of the communication chains and communication blocks where the current metering device is located.

[0035] The server determines whether all first metering parameters are within the preset range. If not, it obtains the second metering parameters of the other communication chain and communication block where the current metering device is located.

[0036] If the server checks whether all second measurement parameters are within the preset range, and if not, it is determined that the current measurement device is malfunctioning.

[0037] To achieve the above objectives, this application also provides the following technical solutions:

[0049] This application divides all metering equipment in a power plant into multiple communication blocks based on metering area, and further into multiple communication chains based on metering object. Each communication block contains multiple metering devices, and each communication chain contains multiple metering devices; that is, the same metering device is simultaneously located in one communication block and one communication chain. At preset time intervals, the application monitors the first metering parameter of the current metering device via one of the communication chains and communication blocks, determining whether the first metering parameter is within a preset range. If any first metering parameter exceeds the preset range, the application obtains the second metering parameter of the other communication chain and communication block, checking whether all second metering parameters are within the preset range. If any second metering parameter exceeds the preset range, the current metering device is deemed to be malfunctioning. This application achieves self-judgment capabilities by repeatedly determining the same metering device's location within its block and its corresponding communication chain, using a double verification method. If the results of the two determinations differ, it is considered a misjudgment. This allows the metering equipment in the power plant to eliminate misjudgments at the equipment level, eliminating the need for manual on-site inspection. Attached Figure Description

[0054] The technical solutions of 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 the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0055] The terms "first," "second," and "third" in this application are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movements between components in a specific orientation (as shown in the figures). If the specific orientation changes, the directional indications also change accordingly. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0056] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0057] like Figure 1 As shown, a networking method for energy metering in a power plant is described. The power plant includes several metering ports located at different locations. Each metering port includes at least two gateway devices and several metering devices. The networking method includes the following steps:

[0058] Step S1: Obtain the building information of the power station and generate a three-dimensional layout based on the building information.

[0059] Step S2: Obtain the first location information of each gateway device and the second location information of each metering device, and output them to the three-dimensional layout respectively.

[0060] Step S3: Divide the three-dimensional layout into at least two measurement regions using the first preset strategy.

[0061] Step S4: Use the second preset strategy to communicate with metering devices located in the same metering area to form at least two communication blocks, each communication block being communicated with a gateway device.

[0062] Step S5: Obtain the metering object of each metering device and connect the metering devices of the same metering object with the third preset strategy to form at least two communication chains, and each communication chain connects to a gateway device.

[0063] Step S6: Load the first isolation protocol based on each communication block and load the second isolation protocol based on each communication chain.

[0064] Preferably, in this embodiment, both the communication block and the communication chain are virtual functional divisions based on a virtual three-dimensional layout, and the above steps can be implemented by setting up an Internet of Things (IoT) in this embodiment.

[0065] In this embodiment, the power station includes several rooms of different sizes and locations on the building level. Each room contains metering equipment for different metering objects (such as the 10kV I, II, and III sections of the power generation section, the lighting group, the self-use group, the peripheral group, etc.).

[0066] Preferably, the Internet of Things (IoT) installed at the power station may include a sensing and identification layer, a network construction layer, and a platform management and service layer.

[0067] The sensing and identification layer is the foundational layer of the overall IoT architecture, primarily responsible for collecting and acquiring information for the IoT. This information collection and acquisition mainly occurs through the electricity meters located in each room.

[0068] In the overall architecture of the Internet of Things (IoT), the network infrastructure layer is primarily responsible for the transmission of network signals and information, mainly by transmitting sensing information to the upper layers and control commands to the lower layers. The network infrastructure layer transmits the signals and information collected by the sensing and identification layer to the platform management service layer, and simultaneously transmits the control commands from the platform management service layer to the integrated application layer. The network infrastructure layer primarily achieves this information transmission through wired transmission (e.g., Ethernet, fiber optics) and wireless transmission (e.g., 4G, 5G, Wi-Fi).

[0069] The platform management service layer is the core of the overall architecture of the Internet of Things. It mainly solves problems such as how to store, retrieve, and use data, as well as data security and privacy protection. The platform management layer is mainly used to integrate and utilize the information collected by the sensing and identification layer through technologies such as big data and cloud computing.

[0070] Applying the above-described IoT architecture to the power plant in this embodiment mainly manifests in the following ways:

[0071] The perception and identification layer consists of metering devices in all rooms, the network construction layer consists of all communication links and all communication blocks, and the platform management service layer is the processing and control carrier for steps S1 to S6 above.

[0072] Preferably, the isolation protocol can be set as a security-related data transmission protocol such as a forward isolation protocol or a reverse isolation protocol.

[0073] Furthermore, after step S6, the following steps are also included:

[0074] Step S10: The first metering parameter of the current metering device is obtained based on one of the communication chain and communication block where the current metering device is located, according to the preset interval.

[0075] Step S20: Determine whether the first measurement parameter is within the preset range. If the first measurement parameter is not within the preset range, then proceed to step S30.

[0076] Step S30: Obtain the second measurement parameter of the other device in the communication chain and communication block where the first measurement parameter is not located in the preset range.

[0077] It should be noted that the other step in step S30 is based on one of the steps in S10. When step S10 obtains parameters through the communication chain where the current metering device is located, then step S30 obtains parameters through the communication block where the current metering device is located; if step S10 obtains parameters through the communication block where the current metering device is located, then step S30 obtains parameters through the communication chain where the current metering device is located.

[0078] To further explain, the design intent of this embodiment is to repeatedly acquire the metering parameters of the same metering device through communication blocks and communication chains respectively, so as to eliminate misjudgments.

[0079] Step S40: Determine whether all second measurement parameters are within the preset range. If any second measurement parameter is not within the preset range, proceed to step S41. If all second measurement parameters are within the preset range, proceed to step S42.

[0080] Step S41: Determine that the current metering equipment is malfunctioning.

[0081] Step S42: It is determined that the communication chain or communication block where the current metering device is located has generated a misjudgment operation.

[0082] Step S50: Locate the communication chain where the current metering device is located, and obtain the third metering parameters of other metering devices in the current communication chain.

[0083] It should be noted that step S50 is the next step after step S40. When it is determined that the metering equipment is abnormal, it is necessary to further verify whether there is an abnormality in the communication chain. Steps S41 and S42 are the two judgment results of step S40.

[0084] Step S60: Determine whether all third measurement parameters are within the preset range. If all third measurement parameters are within the preset range, proceed to step S61; if any third measurement parameter is not within the preset range, proceed to step S62.

[0085] Step S61: Determine that the current communication link is abnormal.

[0086] Step S62: Cancel the misjudgment operation and determine that the current metering equipment is abnormal.

[0087] Furthermore, after step S42, the following steps are also included:

[0088] Step S100: Locate the communication block where the current metering device is located, and obtain the fourth metering parameters of other metering devices in the current communication block.

[0089] Step S200: Determine whether all fourth measurement parameters are within the preset range. If all fourth measurement parameters are within the preset range, proceed to step S201; if any fourth measurement parameter is not within the preset range, proceed to step S202.

[0090] Step S201: Determine that the current communication block is abnormal.

[0091] Step S202: Cancel the misjudgment operation and determine that the current metering equipment is abnormal.

[0092] It should be noted that the design intent of this embodiment is to perform self-checks on the communication block and communication chain respectively, so as to prevent further misjudgments caused by abnormalities in the communication block and communication chain.

[0093] Furthermore, step S3 specifically includes the following steps:

[0094] Step S31: Obtain the building information of the power station and define the building information as a three-dimensional layout.

[0095] Step S32: Obtain the structural features of the building information, distribute power stations according to the structural features to form at least two power station sub-rooms, and define each power station sub-room as a metering area.

[0096] Step S33: Establish a first relay station in the current metering area. The first relay station is connected to each metering device in the current metering area to form a communication block in the current metering area.

[0097] Furthermore, step S5 specifically includes the following steps:

[0098] Step S51: Obtain the second position information of the measuring devices belonging to the same measuring object in the three-dimensional layout.

[0099] Step S52: Connect each metering device of the same metering object sequentially according to each second location information using the shortest connection strategy to form a metering device chain.

[0100] Step S53: A second transfer station is set up at the beginning or end of the metering equipment chain. The second transfer station is connected to the current metering equipment chain to form a communication chain.

[0101] Furthermore, following step S53, the following steps are also included:

[0102] Step S1000: Connect all first relay stations and all second relay stations to the server for communication.

[0103] In step S2000, the server monitors the first metering parameter of the current metering device through one of the communication chains and communication blocks of the current metering device at preset intervals.

[0104] In step S3000, the server determines whether all first measurement parameters are within the preset range. If any first measurement parameter is not within the preset range, then step S3001 is executed.

[0105] Step S3001: Obtain the second metering parameters of the other communication chain and communication block where the current metering device is located.

[0106] Step S4000: Check if all second measurement parameters are within the preset range on the server side. If any second measurement parameter is not within the preset range, then proceed to step S4001.

[0107] Step S4001: Determine that the current metering equipment is malfunctioning.

[0108] It should be noted that in this embodiment, the server performs the above steps to detect and verify the measurement parameters again, but the data processing carrier is located on the server.

[0109] This embodiment divides all metering equipment in a power plant into multiple communication blocks based on metering area, and further divides them into multiple communication chains based on metering object. Each communication block contains multiple metering devices, and each communication chain contains multiple metering devices. That is, the same metering device is simultaneously located in one communication block and one communication chain. At preset time intervals, the system monitors the first metering parameter of the current metering device through one of the communication chains and communication blocks, determining whether the first metering parameter is within a preset range. If any first metering parameter exceeds the preset range, the system obtains the second metering parameter from the other communication chain and communication block, checking whether all second metering parameters are within the preset range. If any second metering parameter exceeds the preset range, the current metering device is determined to be abnormal. This application performs repeated checks on the same metering device, both within its block and on its link, using a double verification method. If the results of the two checks differ, it is determined to be a misjudgment, giving the metering equipment in the power plant a self-judgment function. This eliminates misjudgments at the equipment level, eliminating the need for manual on-site inspection.

[0110] like Figure 2 As shown, this embodiment provides an example of a networking device for power plant energy metering. In this embodiment, the networking device is applied to the networking method for power plant energy metering as described in the above embodiment.

[0114] Furthermore, the networking device also includes a fourth metering parameter acquisition module and a fourth metering parameter judgment module that are electrically connected in sequence to the third metering parameter judgment module.

[0115] The fourth metering parameter acquisition module is used to locate the communication block where the current metering device is located and to acquire the fourth metering parameters of other metering devices in the current communication block. The fourth metering parameter judgment module is used to judge whether all fourth metering parameters are within a preset range. If all fourth metering parameters are within the preset range, the current communication block is judged to be abnormal. If any fourth metering parameter is not within the preset range, the misjudgment operation is canceled and the current metering device is judged to be abnormal.

[0116] Furthermore, the metering area division module includes a first metering area division sub-module, a second metering area division sub-module, and a third metering area division sub-module that are electrically connected in sequence.

[0117] The first metering area division submodule is used to obtain the building information of the power station and define the building information as a three-dimensional layout; the second metering area division submodule is used to obtain the structural features of the building information, distribute the power station according to the structural features to form at least two power station sub-rooms, and define each power station sub-room as a metering area; the third metering area division submodule is used to establish a first transfer station in the current metering area, and the first transfer station is connected to each metering device in the current metering area to form a communication block of the current metering area.

[0120] Furthermore, the networking device also includes a server-side monitoring module, a server-side first judgment module, and a server-side second judgment module, which are electrically connected in sequence to the third communication link forming module.

[0121] The server-side connection module is used to connect all first relay stations and all second relay stations to the server for communication. The server-side monitoring module is used to monitor the first metering parameters of the current metering device through one of the communication chains and communication blocks of the current metering device at preset time intervals.

Each communication block contains multiple metering devices, and each communication chain contains multiple metering devices. That is, the same metering device is simultaneously located in one communication block and one communication chain. At preset time intervals, the system monitors the first metering parameter of the current metering device through one of the communication chains and communication blocks, determining whether the first metering parameter is within a preset range. If any first metering parameter exceeds the preset range, the system obtains the second metering parameter from the other communication chain and communication block, checking whether all second metering parameters are within the preset range. If any second metering parameter exceeds the preset range, the current metering device is determined to be abnormal. This application performs repeated checks on the same metering device, both within its block and on its link, using a double verification method. If the results of the two checks differ, it is determined to be a misjudgment, giving the metering equipment in the power plant a self-judgment function. This eliminates misjudgments at the equipment level, eliminating the need for manual on-site inspection.
