Description

Technical Field

[0001] The present invention relates to the technical field of electric power systems, and in particular to a safety protection method and system for electric energy meters. Background Art

[0002] With the rapid development of power systems, in order to ensure the accurate transmission of power systems in industrial production, electric energy meters are usually used to collect and detect the power data transmitted in the power system in real time. Among them, the unstable voltage in the power system will cause the current to surge or drop sharply, damaging the electric energy meter. Therefore, in order to ensure the safe use of the electric energy meter, it is necessary to control the performance of the power data transmitted in the power system, for example, using a voltage stabilizer as the pre-protection system of the electric energy meter.

[0003] At present, the existing safety protection method for electric energy meters usually directly installs electric energy meter voltage stabilizers. However, since many electric energy meters are required for power data detection in an electric power system, if each electric energy meter is equipped with a voltage stabilizer, a large amount of equipment cost is required. In addition, when an electric energy meter causes an abnormal alarm or power-off protection due to its own fault, it will also affect the voltage stabilization effect of the electric energy meter in other circuits, resulting in over-protection of the electric energy meter, which greatly affects the normal operation of the entire power system.

[0057] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0058] The embodiment of the present invention provides a safety protection method for an electric energy meter, such as Figure 1 As shown, the method includes:

[0059] 101. Obtain the initial electricity meter network for the industrial power system.

[0060] In the embodiment of the present invention, the industrial power system is a power system that mainly supplies power to industrial power equipment. The network coverage of the industrial power system can be an industrial area, for example, an industrial park where multiple industrial production enterprises gather, or it can be a power system of an independent industrial enterprise, for example, a large chemical enterprise, a large steelmaking enterprise, etc. The embodiment of the present invention does not specifically limit the power consumption area covered by the industrial power system. The initial electric energy meter network is a network composed of the connection paths between all electric energy meters, voltage regulators, transformers and power equipment that constitute the industrial power system, including multiple electric energy meter nodes, multiple voltage regulator nodes, at least one transformer node and multiple power equipment. The connection relationship between the above nodes can be a tree connection, or a connection relationship that coexists in a ring and a tree. This mainly depends on the connection relationship between the transformers. If multiple transformers are connected to the same bus at the same time and share the load, the transformers are connected in parallel, and the electric energy meters connected to the transformers, the voltage regulators connected to the electric energy meters and the power equipment together form a tree structure. If multiple transformers and electrical equipment are connected into a closed loop, the energy meter, voltage stabilizer and electrical equipment connected to each transformer form a tree structure, that is, a connection relationship in which both the loop and the tree exist. The current execution subject is a platform server for configuring and controlling the power network of the industrial power system.

[0061] In an embodiment of the present invention, for further explanation and limitation, as Figure 2 As shown, before the step of obtaining the initial electric energy meter network of the industrial power system, the method further includes:

[0062] 201. Determine the electricity consumption model of the industrial power system.

[0063] 202. Generate multiple electric energy meter nodes, voltage stabilizer nodes, and transformer nodes based on the type of electric users, the number of electric users, and the distance between electric users in the electric user model.

[0064] 203. Output the electric energy meter node, the voltage regulator node, and the transformer node through the front-end interface of the industrial power system for selection by an operator.

[0065] 204. Receive selected electric energy meter nodes, voltage regulator nodes and transformer nodes, and connect and combine node connection ends of the electric energy meter nodes, voltage regulator nodes and transformer nodes with connection ends of selected electrical equipment to obtain an initial electric energy meter network.

[0066] In an embodiment of the present invention, the power consumption model is used to characterize a virtual model of an industrial power system built based on a simulated power consumption component. In an industrial power system, in order to ensure the power supply stability of power consumption equipment, a multi-way power supply network is usually configured for a power consumption equipment. For example, a power consumption equipment is usually configured with a main power supply and a dedicated backup power supply; or the power supplies of multiple power consumption equipment are mutually backup. In other words, the power consumption equipment of the industrial power consumption enterprise corresponding to the industrial power system is relatively fixed, and there are multiple choices for which transformer output is used to power the power consumption equipment, and which energy meter and voltage stabilizer are used to collect and safely protect the power consumption of the power consumption equipment, that is, the path for powering fixed power consumption equipment is optional. Therefore, the current execution subject provides a front-end interface of an industrial power system, so that the user can select and configure the power transmission path of different power consumption equipment through this front-end interface before the current execution subject obtains the initial energy meter network of the industrial power system. Among them, the front-end interface is an interface that can realize user interaction, and the user can input the selection of power consumption equipment and the connection configuration of different electrical equipment nodes through this interface.

[0067] In order to achieve convenient selection for users, the current execution subject automatically generates multiple energy meter nodes, voltage regulator nodes and transformer nodes according to the type of electrical equipment, the number of electrical equipment and the distance of electrical equipment. Due to different types of electrical equipment, different numbers of electrical equipment and distance of electrical equipment, the number of energy meter nodes, voltage regulator nodes and transformers that need to be configured can be inferred and designed based on the logic of the electrical circuit. Therefore, the number of energy meter nodes, voltage regulator nodes and transformer nodes corresponding to different types of electrical equipment, different numbers of electrical equipment and distance of electrical equipment can be configured in advance. In the process of node generation, the number of energy meter nodes, voltage regulator nodes and transformer nodes is matched through the pre-configured mapping relationship. It can also be generated according to the pre-configured actual layout of energy meter points, voltage regulators and transformers. At this time, these generated energy meter nodes, voltage regulator nodes and transformer nodes are completely corresponding to the actual equipment layout. The above two generation methods can be selected according to actual application requirements. If the configuration of the energy meter, voltage stabilizer and transformer in the current industrial power system is relatively simple or conforms to the industry standard and conventional logic, the automatic generation method can be adopted; if the configuration of the energy meter, voltage stabilizer and transformer in the current industrial power system is relatively complex or the number of configurations is relatively special and does not conform to the conventional electrical appliance configuration, the method of presetting the actual electrical appliance layout generation can be adopted, and the embodiment of the present invention does not make specific restrictions. Among them, the generation process of the above nodes of the circuit layout can be implemented using simulation platforms such as MATLAB / Simulink.

[0068] Since the connection relationship between each node is relatively flexible, the above generation process only generates the energy meter node, voltage regulator node and transformer node, but does not generate the connection relationship between each node. Instead, the generated energy meter node, voltage regulator node and transformer node are displayed on the front-end interface so that the user can configure the connection end of each node and the connection end of the power consumption equipment by clicking and selecting in this front-end interface according to the actual power transmission needs, so as to realize the construction of the initial energy meter network. The automatic generation of energy meter nodes, voltage regulator nodes and transformer nodes combined with the user's configuration of the node connection relationship not only meets the user's requirements for the flexibility of industrial power system network configuration, but also improves the convenience of user configuration.

[0069] It should be noted that in the process of users selecting the node connection ends of the electric meter nodes, voltage stabilizer nodes, and transformer nodes and the connection ends of the electrical equipment, the current execution entity can also compare the user's selection with the actual circuit connection relationship to realize the feasibility verification of the user's operation. If it is found that the node connection relationship selected by the user cannot be realized, prompt information will be output in time on the front-end interface to ensure the accuracy of the configuration.

[0070] 102. When a power consumption task is received, parse the power transmission parameters and the power consumption object of the power consumption task, and select the task network from the initial electric energy meter network according to the power transmission parameters and the power consumption object.

[0071] In an embodiment of the present invention, the initial electric energy meter network is a global electric energy meter network of an industrial power system, that is, this network includes all electric energy meters, electric equipment, transformers and voltage stabilizers in the industrial power system, regardless of whether the electric equipment is in a power consumption state. When a power consumption task is received, a task network is screened from the initial electric energy meter network to transmit the electric energy on the power generation side to the power equipment side through the screened task network. Among them, the power consumption task is a task triggered when the power equipment needs to start running, so that the corresponding industrial power system prepares for the upcoming power demand. The power consumption task can be triggered based on the production plan submitted in advance by the industrial power user. For example, the production plan provided by an enterprise is to start the power equipment at 10 o'clock every night, and the power consumption task is sent to the current execution subject at 9:30 every night. It can also be triggered based on a real-time submitted power consumption request. For example, the power user initiates a power consumption request through the interactive interface before using electricity and selects the power consumption object. The power consumption task can directly carry power transmission parameters and power consumption objects, or only carry power consumption objects, and then obtain the power transmission parameters by matching the mapping relationship between power consumption objects and power transmission parameters. Among them, the power consumption object is the power consumption related information in the power consumption task, and the power consumption object includes the rated power of multiple power consumption devices. The power transmission parameters define the transmission method of electric energy, such as the maximum power, minimum power, voltage level, and the number of voltages required.

[0072] It should be noted that filtering out task networks from the global energy meter network through power consumption tasks is a process of dividing the global energy meter network into networks that are performing power consumption tasks and networks that are not performing power consumption tasks. Figure 3 An initial electric energy meter network is shown, and the network formed by the electrical equipment selected by the dotted line box in the figure is the task network, and different line types represent different network paths. Since the plant energy storage equipment is a backup power source for the power grid power bus, it is a selective use relationship, so the voltage stabilizer 2 can be shared by the two lines. Through the screening of the task network, in the subsequent electric energy meter safety detection process, detection and safety control can be selectively carried out, thereby improving the detection effectiveness and reducing resource consumption. In addition, through the division of the task network, the voltage stabilizers in the network that will not run at the same time will be shared, and multiple electric energy meters can share one voltage stabilizer, thereby reducing the equipment cost of electric energy meter safety monitoring.

[0073] In one embodiment of the present invention, for further explanation and limitation, the selecting a task network from the initial electric energy meter network according to the power transmission parameter and the power user includes:

[0074] Based on the device model and the type of electricity consumption, select the electrical equipment matching the electricity consumption object from the initial electric energy meter network;

[0075] Displaying a network line associated with the power-consuming device in a front-end interface of the industrial power system, and marking the power transmission parameters on the network line;

[0076] The network lines are screened based on the received line determination instruction to obtain a task network.

[0077] In an embodiment of the present invention, the equipment model and power type of each power-consuming equipment in the initial power meter network are matched with the power consumption represented by the power consumption object to determine the power-consuming equipment that needs to be powered. Among them, the power consumption type is used to characterize the power consumption type of the power-consuming equipment, such as high-power power-consuming equipment, low-power power-consuming equipment, 380V high-voltage equipment, 220V low-voltage equipment, etc. After the power-consuming equipment is determined, the network line connected to the power-consuming equipment in the initial power meter network is displayed through the front-end interface, that is, the network line of the associated power-consuming equipment. After the associated network lines are determined to be multiple, the corresponding power transmission parameters are marked for each line. Among them, the power transmission parameters include power supply duration, power supply pole value and transformer level. Among them, the transformer level can be determined according to the model and number of transformers in the line, and the transformer level and power supply duration can be determined according to the energy storage capacity of the power supply corresponding to the current network line, and the continuous working tolerance time of each component in the line. The power supply pole value is the maximum or minimum power supply voltage, the maximum or minimum power supply current and the maximum or minimum power supply power, etc., which can be determined according to the rated use specifications of each component in the power supply and network line. Among them, the purpose of marking the power transmission parameters is to provide a basis for the user's task network selection. Therefore, after completing the marking, the initial electric energy meter network marked with the power transmission parameters is displayed on the front-end interface, so that the user can select the task network for executing the power consumption task from the network line through the interactive control according to the power transmission parameters. After the user completes the selection and submits, the current execution subject receives the line determination instruction generated according to the user's submission operation, and determines the task network from the initial electric energy meter network according to the line determination instruction.

[0078] It should be noted that the line determination instruction carries information parameters for changing the power transmission parameters and a node network for changing the network line. That is to say, the user can directly select the marked network line and perform the power consumption task according to the power transmission parameters marked by the selected network line by default. However, when the path of any network line or the power transmission parameters marked by any network line do not meet the operator's needs, the operator can select a network line (selected network line) that is closest to the expected network line connection relationship and power transmission parameters. Then adjust this line, specifically including adjusting the connection nodes of the existing network line, thereby generating a node network for changing the network line, and adjusting the power transmission parameters marked in the network line, thereby generating information parameters for changing the power transmission parameters. When the current execution subject receives the information parameters carrying the changes to the power transmission parameters and the node network for changing the network line, it parses the changed information parameters and the changed nodes, and modifies the power transmission parameters marked in the selected network line according to the corresponding changes, and updates the path of the selected network line according to the changed node connection relationship. The initial electric energy meter network marked with power transmission parameters is displayed through the front-end interface, providing a comprehensive selection basis for the operating user, making it easier to select the task network. In addition, it also provides users with the function of flexibly adjusting the existing network lines, thereby ensuring the flexibility of task line screening.

[0079] 103. Determine the operation detection conditions of the electric energy meters in the task network according to the number of electric energy meters, the number of voltage stabilizers, the number of transformers and the number of electrical equipment in the task network, and monitor according to the electric energy meter detection conditions when the task network starts the power operation.

[0080] In an embodiment of the present invention, after determining the task network, the number of transformers, the number of electric energy meters, the number of voltage stabilizers, and the number of corresponding electrical equipment used in the task network can be analyzed. Since different numbers of transformers determine the voltage change of electric energy transmission, different numbers of voltage stabilizers and electric energy meters also need to correspond to different electric energy meter operation detection conditions. Therefore, before starting the power operation of the task network, it is necessary to determine the electric energy meter operation detection conditions based on the number of transformers, the number of electric energy meters, and the number of voltage stabilizers. When the task network starts the power operation, the current execution subject monitors each electric energy in the task network according to the electric energy meter detection conditions to determine whether it is necessary to perform safety monitoring on the electric energy meter. Among them, the electric energy meter operation detection condition is the trigger condition for starting the safety monitoring of the electric energy meter. The safety monitoring of the electric energy meter is started only when the operating state of the electric energy meter in the task network meets the electric energy meter operation detection condition.

[0081] It should be noted that the safety monitoring of the energy meter is mainly carried out to timely monitor the impact of power fluctuations on the energy meter. By monitoring the operation detection conditions of the energy meter, it is possible to avoid uninterrupted safety monitoring throughout the process while ensuring the timeliness of the start of safety monitoring, thereby improving the efficiency of safety monitoring.

[0082] In one embodiment of the present invention, for further explanation and limitation, the determining of the operation detection conditions of the electric energy meters in the task network according to the number of electric energy meters, the number of voltage stabilizers, the number of transformers, and the number of electrical equipment in the task network includes:

[0083] Retrieving a reference mapping relationship of electric energy meter detection matching the electric energy task, and counting the number of electric energy meters, voltage stabilizers, transformers, and electric equipment in the task network;

[0084] Based on the electric energy meter detection reference mapping relationship, the electric energy meter operation detection conditions that match the number of the electric energy meters, the number of the voltage stabilizers, the number of the transformers and the number of electrical equipment are matched.

[0085] In the embodiment of the present invention, in addition to the situation where obvious power fluctuations occur directly in the power grid, power fluctuations are also more likely to occur when the power consumption of the power equipment is large; and when the power load of the power equipment changes for a long time, it is also easy to cause power fluctuations. Therefore, the power meter operation detection condition can be a detection condition configured from one or more dimensions of power fluctuation dimension, time dimension, and power consumption dimension, that is, the power meter operation detection condition includes operation time detection condition, power detection condition, and power fluctuation detection condition. The selection of the power meter operation detection condition is based on the pre-constructed power meter detection reference mapping relationship. Among them, the power meter detection reference mapping relationship includes power meter operation detection conditions corresponding to different numbers of power meters, voltage stabilizers, transformers, and power equipment. The number of power meters, voltage stabilizers, transformers, and power equipment parsed from the task network can be matched from the power meter detection reference mapping relationship to the power meter operation detection condition that meets the current power consumption task set task network.

[0086] Among them, the reference mapping relationship of the energy meter detection can be based on the experience configuration of the historical energy meter safety monitoring, or it can be constructed based on the abnormal situation prediction data of different numbers of energy meters, voltage regulators, and transformers based on the pre-trained neural network model. For example, the model is used to predict the network with different numbers of energy meters, voltage regulators, and transformers. When it is confirmed that the energy meter safety anomaly occurs, the corresponding operation time, power supply, and power fluctuation value of the network line. The predicted operation time, power supply, and power fluctuation value are constructed into a pair of mapping relationships with the corresponding model input. Among them, the pre-trained neural network model can be a long-short memory model. The training samples of the model are constructed based on the safety anomaly data of network lines with different numbers of energy meters, voltage regulators, transformers, and electrical equipment in the historical time period.

[0087] 104. When the electric energy meter detection condition is triggered, obtain meter operation data of the electric energy meter, and perform safety monitoring based on the meter operation data.

[0088] In an embodiment of the present invention, in response to the triggering of the detection condition of the electric energy meter, the current execution subject obtains the meter operation data of each electric energy meter in the task network, so as to judge whether the electric energy meter has safety hazards based on the meter operation data of the electric energy meter. Among them, the meter operation data may include power data, current data, voltage data, pulse indicator light flashing image data, etc. For example, under normal circumstances, the power data should increase gradually. If the power data fluctuates abnormally or decreases suddenly, it may indicate that there is a problem with the electric energy meter. For another example, if the indicator light flashes only once within 10 minutes or there is no obvious change, it means that the electric energy meter is operating normally; if the flashing is frequent or abnormal, it may indicate that there is a problem with the electric energy meter. For another example, if the current data and voltage data of the electric energy meter exceed the corresponding preset thresholds, it may also indicate that there is an abnormality in the current electric energy meter.

[0089] 105. If the security monitoring fails, an alarm message of the electric energy meter or abnormal power consumption information of the task network is generated and sent to the mobile inspection terminal for offline security detection.

[0090] In the embodiment of the present invention, if the result of the safety monitoring of the electric energy meter is abnormal, that is, it fails to pass the safety monitoring, the alarm information of the electric energy meter or the abnormal power consumption information of the task network is generated, and the alarm information or abnormal information is sent to the mobile inspection terminal so that the inspection personnel can perform offline safety detection. What kind of information is generated can be determined according to the number or proportion of electric energy meters that fail to pass the safety monitoring. For example, there are 10 electric energy meters in the task network, and only one electric energy meter has a safety monitoring abnormality. It is highly likely that the single meter is abnormal, rather than the power consumption abnormality of the task network, and the alarm information of this electric energy meter is generated. For another example, there are 6 electric energy meters in the task network, and 3 electric energy meters have a safety monitoring abnormality. The proportion of abnormal electric energy meters is as high as 50%. At this time, the abnormality of the electric energy meter is most likely not a single meter abnormality of the electric energy meter, but caused by the abnormality of the entire power consumption network, and the abnormal power consumption information of the task network is generated. The mobile inspection terminal can be a portable device of the inspection personnel, such as a telephone, an inspection alarm device, etc., which is not specifically limited in the embodiment of the present invention. By generating alarm information for the electric energy meter or abnormal power consumption information for the task network according to different security monitoring situations, offline inspection personnel can easily identify the type of abnormality and the urgency of handling it, thereby conducting offline safety inspections more efficiently and improving the efficiency of resolving security monitoring abnormalities.

By generating the curve, a more comprehensive safety monitoring data reference can be provided to the user. It is also beneficial for the user to observe the safety monitoring curve through the front-end interface, so as to discover the expected safety hazards in advance.
