Description

TECHNICAL FIELD

[0001] The present application relates to a method for monitoring an electrical energy transmission system. BACKGROUND

[0002] Electrical energy transmission systems are monitored in order to achieve reliable, safe and efficient energy provision, to increase productivity, to reduce unplanned downtime and to improve performance. An electrical energy transmission system is understood here, for example, as a local system, such as a switching device, or as a spatially extended system, such as an electrical energy transmission network. Electrical energy transmission systems have a large number of system components, for example transformers, bushings, measuring transformers, coils, circuit breakers, arresters and disconnectors. Such system components are nowadays equipped with sensors and digital communication interfaces with which operating data of the system components are acquired and communicated in order to monitor the electrical energy transmission system for the purpose of optimizing operation and reducing errors and faults. For this purpose, the acquired data are evaluated and processed by an application software in order to display the operating state of the electrical energy transmission system and its system components to a user of the application software and, for example, to indicate critical operating states, errors or faults if necessary. However, due to the large number of different system components, it is often confusing and cost-intensive for the user to filter out the information relevant to him from the large amount of available information individually. SUMMARY

[0003] The technical problem addressed by the present application is to provide an improved method for monitoring an electrical energy transmission system.

[0004] The above-mentioned technical problem is solved according to the present application by a method having the features according to the present application and by a computer program having the features according to the present application.

[0005] With the method according to the present application, an electrical energy transmission system having a plurality of system components is monitored, which system components each have a sensor unit designed to acquire measurement data relating to at least one operating parameter of the system component and a communication interface designed to transmit the measurement data and component information about the system component. The measurement data and the component information about the system components are transmitted via the communication interfaces of the system components into a data cloud, and a graphical user interface is provided, which is designed to visualize information about the electrical energy transmission system, which information is generated from the measurement data and the component information transmitted into the data cloud. A user profile is created for a user of the graphical user interface, which user profile determines the information displayed to the user.

[0006] The method according to the invention enables the visualization of information about a power transmission system for monitoring purposes. In particular, it allows for the visualization of a so-called digital twin of the power transmission system. The transmission of measurement data and component information to a data cloud advantageously provides this data to different users location-independently. The creation of user profiles enables the display of information associated with a user's profile, which determines the information displayed to the user. In other words, this achieves user-dependent filtering of the displayed information. This makes it easier for users to operate the graphical user interface while allowing for the selection and display of user-relevant information in a manner tailored to the user and their interests.

[0007] In one embodiment of the invention, a user profile is stored, and when the user invokes the graphical user interface (GUI), information determined by the user profile is displayed to the user. Thus, when the GUI is invoked, the user is advantageously shown the information selections defined by the user profile, without the user having to create a user profile each time the GUI is invoked.

[0008] In another embodiment of the invention, the graphical user interface has checkboxes for selecting information, and a user profile is created based on the checkboxes marked by the user. This allows for the simple creation of a user profile based on the checkboxes marked by the user. Furthermore, it enables the user to determine their user profile simply by marking the checkboxes.

[0009] In another embodiment of the invention, the user profile can be modified by the user, for example, by changing marked checkboxes. Thus, the user profile can be easily adapted to the user's changing interests.

[0010] In another embodiment of the invention, the graphical user interface has multiple filtering levels with checkboxes, which are logically constructed and associated with each other, such that the marking of a combination of checkboxes in a filtering level determines the checkboxes of the filtering level that follows that level and are displayed by the graphical user interface. This advantageously allows for hierarchical determination of user profiles across multiple filtering levels and further simplifies the creation of user profiles through the clear structure of the checkboxes.

[0011] For example, checkboxes in the first filtering level can be used to select groups of system components individually. At least one such group may include system components with similar functions. Alternatively or additionally, at least one group may include system components arranged at a location associated with the system component in the power transmission system or in a spatial area associated with the system component in the power transmission system. Thus, in the first filtering level, a user can select a group of system components relevant to that user, for example, by the function of the system components or the spatial arrangement of the system components.

[0012] In another embodiment of the invention, checkboxes in the second filter level can be used to select a subgroup of a group of system components that can be selected using checkboxes in the first filter level. This advantageously allows for refinement of the selection of system components selected through one or more groups in the first filter level by selecting one or more subgroups of these groups in the second filter level.

[0013] In another design of the invention, individual system components can be selected using checkboxes in a third filtering level. This enables specific selection of particular system components.

[0014] In another embodiment of the invention, checkboxes in the fourth filtering level can be used to select information about system components displayed by the graphical user interface. Such information includes, for example, the temperature of the system component, the pressure in the system component, the current intensity of the current flowing in the system component, the voltage applied to or in the system component, and / or the switching state or switching unit of the system component.

[0015] In another embodiment of the invention, a graphical user interface is provided through application software (so-called App) for terminal devices such as mobile phones (e.g., smartphones) or computers, especially portable computers (e.g., tablets, laptops, laptops). Thus, the graphical user interface can advantageously be implemented and displayed on different terminal devices, especially mobile terminal devices, regardless of location.

[0016] The computer program according to the invention includes instructions that, when implemented on a terminal device, cause the terminal device to implement the graphical user interface described in the invention. Attached Figure Description

[0017] The features, characteristics, advantages, and implementations of the invention described above will become clearer and more apparent in conjunction with the following description of embodiments, which are illustrated in more detail with reference to the accompanying drawings. In the drawings:

[0018] Figure 1 A block diagram showing the power transmission system, data cloud, and mobile terminal devices is provided.

[0019] Figure 2 The diagram illustrates the checkboxes for different filtering levels displayed by the graphical user interface. Detailed Implementation

[0020] Figure 1 A block diagram of the power transmission system 1, the data cloud 3, and the terminal equipment 5 is shown.

[0021] The power transmission system 1 includes multiple system components 7 and 8, each of which has sensor units 9 and 10 and communication interfaces 11 and 12. The sensor units are designed to collect measurement data of at least one operating parameter of the system components 7 and 8, and the communication interfaces are designed to transmit the measurement data and component information of the system components 7 and 8 to the data cloud 3. Figure 1 Only two system components, 7 and 8, are shown as an example.

[0022] System components 7 and 8 are, for example, transformers, bushings, measuring transformers (current or voltage transformers), coils, circuit breakers, surge arresters, or disconnectors in switching equipment.

[0023] Sensor units 9 and 10 of system components 7 and 8 collect, for example, the temperature of system components 7 and 8, the pressure in system components 7 and 8, the current intensity of the current flowing in system components 7 and 8, and / or the voltage applied to or applied to system components 7 and 8 as measurement data.

[0024] The communication interfaces 11 and 12 of system components 7 and 8 transmit, for example, identifiers associated with system components 7 and 8 (e.g., sequences of data representing numbers, letters, and / or special characters) and / or data representing the type of system components 7 and 8 or at least one characteristic of system components 7 and 8 as component information about system components 7 and 8 to the data cloud 3. The communication interfaces 11 and 12 of system components 7 and 8 are designed, for example, to transmit measurement data from sensor units 9 and 10 of system components 7 and 8 and / or component information about system components 7 and 8 wirelessly (e.g., via radio waves) to the data cloud 3.

[0025] Data cloud 3 can be implemented, for example, in the Internet or intranet.

[0026] Terminal device 5 is, for example, a mobile phone (smartphone) or a computer, especially a portable computer (tablet, laptop, laptop computer). Mobile terminal 5 is designed to communicate with data cloud 3, for example, wirelessly (e.g., via radio waves), and to retrieve data from data cloud 3.

[0027] According to the present invention, a graphical user interface 13 is provided, which is designed to visualize information about the power transmission system 1, generated from measurement data and component information transmitted to the data cloud 3. The graphical user interface 13 is provided, for example, by application software implemented on a terminal device 5.

[0028] A user profile is created for the user of the graphical user interface 13, which determines the information to be displayed to the user. The graphical user interface 13, for example, has checkboxes 15 for selecting information, and the user's user profile is created based on the checkboxes 15 marked by the user. The user's user profile is stored, and when the user invokes the graphical user interface 13, the information determined by the user's user profile is displayed to the user. The user profile can be changed by the user, for example, by the user changing the marked checkboxes 15.

[0029] The graphical user interface 13 has multiple filter levels 17 to 20 with checkboxes 15, which are logically constructed and associated with each other, such that the marking of a combination of checkboxes 15 in filter levels 17 to 20 determines the checkboxes 15 displayed by the graphical user interface 13 that follow the filter levels 17 to 20.

[0030] Figure 2 An embodiment of checkboxes 15 with different filtering levels 17 to 20 of the user interface 13, as shown schematically by the graphical user interface 13, is illustrated. Figure 2 The arrows in the text indicate the logical associations between filter levels 17 to 20.

[0031] For example, checkboxes 15 in the first filter level 17 can be used to select groups of system components 7 and 8 respectively. At least one such group includes, for example, system components 7 and 8 with similar functions, such as transformers, circuit breakers, or disconnectors. Furthermore, at least one group may include, for example, system components 7 and 8 arranged at locations associated with system components 7 and 8 in the power transmission system 1 or arranged in spatial areas associated with system components 7 and 8 in the power transmission system 1.

[0032] For example, checkbox 15 of the second filter level 18 can be used to select a subgroup of the group of system components 7 and 8 that can be selected using checkbox 15 of the first filter level 17.

[0033] For example, checkbox 15 in the third filter level 19 can be used to select individual system components 7 and 8.

[0034] For example, checkbox 15 of the fourth filter level 20 can be used to select information about system components 7 and 8 displayed by the graphical user interface 13, such as the temperature of system components 7 and 8, the pressure in system components 7 and 8, the current intensity of the current flowing in system components 7 and 8, and / or the voltage applied to or applied to system components 7 and 8.

[0035] Although the invention has been described and illustrated in more detail through preferred embodiments, the invention is not limited to the disclosed examples and other variations can be derived by those skilled in the art without departing from the scope of protection of the invention.
