It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The monitoring method of the power network provided by the present application may be applied to an application environment as shown in fig. 1, and in the application environment, the monitoring method may include a cloud server 101, a power grid monitoring terminal 102, and a client 103. The cloud server 101 may be a server deployed on a cloud platform, and may be implemented by an independent server or a server cluster composed of a plurality of servers; the grid monitoring terminal 102 may be a terminal for monitoring the power network; the client 103 may communicate with the power network management system and send instructions to control the grid monitoring terminal.
In an embodiment, as shown in fig. 2, a monitoring method for a power network is provided, which is described by taking the method as an example applied to the cloud server 101 in fig. 1, and may include the following steps:
As an example, the grid monitoring terminal may be a power distribution device with a monitoring function in the power network.
A Common Information Modeling (CIM) may be an abstract model describing all the main objects of a power enterprise, in particular objects related to power operation. By providing a standardized method for representing power system resources in terms of object classes and attributes and relationships between them, CIM facilitates integration of Energy Management System (EMS) applications developed independently by different system developers, integration between multiple, independently developed, complete EMS systems, and integration between EMS systems and other systems related to different aspects of power system operation, such as power generation or distribution systems. In one example, the common information model may be understood as: standard objects are provided for interoperability and application programs in the power, water and gas industry that reply to production, transmission, distribution, marketing and retail systems. In the power domain, the common information model defines a standard object model of the power industry for power engineering, planning, management, operation and development and integration of business applications, for example, standards describing power objects and their relationships may be provided.
In practical application, the power grid monitoring terminal can acquire the state signals in the power network, generate the summary signals according to the state information, and send the summary signals to the cloud server. After receiving the summary signal, the cloud server may construct a public information model according to the summary signal. Since the cloud server may have a higher computational power than the local server, control of the power network may be made more efficient by building a common information model at the cloud server.
As an example, the current state information may be information reflecting an operational state of a portion or the whole of the power network. The feedback control signal may be a signal generated by the cloud server after identifying the current state information and used for regulating and controlling the operation state of the power grid monitoring device.
Particularly, a large number of power grid monitoring devices are involved in a power network, the total amount of data collected by each power grid monitoring device is huge, and data in various formats are effectively stored and are convenient to recognize by constructing a public information model, so that convenience of power control is improved, and a monitoring technology can be optimized.
In practical application, after obtaining the public information model, the cloud server may determine current state information of the power network according to the public information model, and generate feedback control information for the power network according to the current state. The public information model is analyzed through the cloud server, the corresponding feedback control signal is automatically generated through the trigger, the monitoring technology can be optimized, the data monitoring recognition rate is improved, the power network monitoring meets the intelligent requirement, and the problem that power network fault finding delay caused by manual monitoring fatigue operation is avoided.
As an example, the operation parameter may be a parameter indicating an operation mode of the power grid monitoring terminal, and the operation state of the power grid monitoring terminal may be changed by adjusting the operation parameter.
After the feedback control information is generated, the feedback control information may be sent to the power grid monitoring terminal, for example, the cloud server may send a plurality of feedback control signals to the power grid monitoring terminal within the coverage area through the broadcast signal, and certainly, under the condition that resources are sufficient, the power grid monitoring terminal may also be notified of the plurality of feedback control signals by using the downlink control information.
After receiving the feedback control information, the power grid monitoring terminal may adjust the power network according to the feedback control signal. Specifically, the power grid monitoring terminal may adjust an operation parameter of the power grid monitoring terminal, for example, adjust parameters such as voltage, current, and load power, so as to achieve the purpose of adjusting the power network.
In this embodiment, the cloud server may obtain a summary signal sent by the power grid monitoring terminal, construct a public information model according to the summary signal, determine current state information of the power network according to the public information model, generate a feedback control signal for the power network according to the current state information, and then send the feedback control information to the power grid monitoring terminal, trigger the power grid monitoring terminal to adjust the power network based on the feedback control signal, so that real-time monitoring and accurate control of the power network are achieved, and control of the power network is facilitated and efficient.
In one embodiment, the method may further comprise the steps of:
obtaining model construction information corresponding to the public information model; and sending the model construction information to a client, wherein the client is used for generating a visual model according to the model construction information and displaying the visual model in a display interface of the client.
As an example, the model build information may be information for building a visualization model, and the model build information may include model features corresponding to the common information model.
In specific implementation, when the power network is monitored manually, since the monitoring system of the power network cannot represent the power network through visualized images, the intuitiveness of data analysis is poor.
In this embodiment, the public information model may include modeling data of the visualization model, such as model construction information, and after the public information model is generated, the cloud server may obtain model construction information corresponding to the public information model and send the model construction information to the client. After receiving the model construction information, the client may establish a visualization model according to the model construction information, and display the visualization model in a display interface of the client, for example, display the visualization model in a browser of the client, and may edit the visualization model in the browser according to an editing instruction after receiving an editing instruction of a user, thereby making control of the power network more intuitive.
In one example, any one or more terminal devices of a personal computer, a notebook computer, a smart phone, a tablet computer and a portable wearable device can be used as a carrier of a client to communicate with a cloud server, and after the visualization model is obtained, the visualization model can be displayed in a display interface of the terminal device, so that the control of the power network is more intuitive and efficient.
In this embodiment, the model construction information corresponding to the public information model is acquired, and the model construction information is sent to the client, so that the client can generate the visual model according to the model construction information and display the visual model in the display interface, and the control of the power network is more intuitive.
In one embodiment, the determining the current state information of the power network according to the common information model may include the steps of:
acquiring a power network object corresponding to a power network and a class and an attribute corresponding to the power network object from the public information model; and determining the current state information of the power network according to the incidence relation among the power network object, the class and the attribute.
As an example, the power network object may correspond to a device in a power network.
The class may be a specific description of a real-world object, for example, after a transformer or a generator is loaded, an entire model of the power system needs to be shown in the EMS system, and faults are analyzed and processed by the EMS system.
The attributes may be information characterizing corresponding features of devices in the power network, and the attributes of the power network object may be defined by assistance of the EMS system, for example, for data attributes, each data attribute may be specific, and the model is constructed by metadata types such as integers, boolean variables, floating point numbers, character strings, and the like.
Specifically, the common information model is used as an information model to describe logical structures and relationships of a plurality of objects in the power system, the common information model may include a plurality of logical packages, each logical package may correspond to a certain part in the power network, the common information model may reflect relationships between classes under the packages through a class diagram of the UML, after attribution is associated with classes in different packages, the packages corresponding to the classes may be labeled, and in the common information model, the classes and images may be used as a tool for analyzing information of the power system in the EMS application program through a common model.
In practical application, the power network object corresponding to the power network and the class and attribute corresponding to the power network object can be obtained from the common information model, the relationship among the power network object, the class and the attribute can be obtained, and further the current state information of the power network can be determined according to the relationship among the power network object, the class and the attribute.
In a specific implementation, the association relationship in the public information model may include, but is not limited to, the following three types: association, aggregation, and generalization.
Associations may represent links between classes. The association in the power network monitoring system may include at least two classes, and the association between the target class and the original class, which need to be described, is realized by constructing an association point. For example, transformers and coils of a power network have a one-to-many coil relationship.
Aggregation is a special case of an association, which is a strong association. The overall class in the power network monitoring system is composed of local classes, and information such as images and files formed by the local classes in each monitoring area network is aggregated into a local and overall mode through a common information model, so that the information is concentrated in the overall relation of the power network.
Generalization is a description of the relationship between general and specific, general and specific. In the generalization relationship, general data information of the power network is embodied into attributes, and forms a certain relationship with the whole power network monitoring system. For example, a knife switch in an electrical power network is a specific class of isolation switches, which are a specific class of conductive devices.
In this embodiment, the power network object corresponding to the power network and the class and attribute corresponding to the power network object may be obtained from the common information model, and the current state information of the power network is determined according to the relationship among the power network object, the class, and the attribute, so as to provide a basis for subsequently generating the corresponding feedback control instruction.
In another embodiment, the determining the current state information of the power network according to the common information model may include the steps of: and analyzing by using a data analysis module according to the public information model to determine the current state information.
As an example, the data analysis module comprises threshold values of various states of the common information model CIM.
Specifically, the current state parameter of the power network may be determined according to the common information model, and a pre-stored state mapping relationship may be obtained from the data analysis module, where the state mapping relationship may include mapping relationships between different state parameters and state information. And further, the current state information of the power network can be determined according to the mapping relation and the state parameters.
In one embodiment, the generating a feedback control signal for the power network according to the current state information comprises:
acquiring a preset signal mapping relation; the signal mapping relation comprises the mapping relation between different state information and a feedback control signal; and generating a feedback control signal aiming at the power network according to the current state information and the signal mapping relation.
In a specific implementation, after the current state information is obtained, a preset signal mapping relationship may be obtained from the state analysis module, where the signal mapping relationship may include mapping relationships between different state information and a feedback control signal, and then a feedback control signal for the power network may be generated according to the signal mapping relationship and the current state information.
In this embodiment, the feedback control signal can be generated according to the current state information and the signal mapping relationship, so that the regulation and control efficiency of the power network is effectively improved.
In one embodiment, the method may further comprise the steps of:
receiving an active control signal of a client; the active control signal is generated based on an input instruction acquired by the client; and sending the active control signal to the power grid monitoring terminal so as to regulate the power network.
In a specific implementation, a worker may input an instruction in the client, for example, the instruction may be input in a browser in the client, and the input instruction may be used to control a working state of the power grid monitoring terminal or adjust an operating parameter of the power grid monitoring terminal. After receiving the input instruction, the client may generate a corresponding active control signal according to the input instruction, and send the active control signal to the cloud server.
After receiving the active control signal, the cloud server can analyze the active control signal and judge whether the active control signal can be executed or not, if so, the active control signal can be sent to the power grid monitoring terminal to trigger the power grid monitoring terminal to adjust the power network based on the active control signal; if not, a rejection message can be fed back to the client. In an example, the cloud server may issue a plurality of active control signals to the power grid monitoring terminal within the coverage area through the broadcast signal, and certainly, in the case of sufficient resources, the cloud server may also notify the power grid monitoring terminal of the plurality of active control signals by using the downlink control information, and the specific method may be selected according to actual requirements, which is not limited in this embodiment.
In this embodiment, the active control signal is sent to the power grid monitoring terminal to adjust the power network, so that the control mode of the power network is more various, and the convenience of power network control is improved.
In an embodiment, as shown in fig. 3, a monitoring method for a power network is provided, which is described by taking the method as an example applied to the power grid monitoring terminal 102 in fig. 1, and may include the following steps:
As an example, the power grid monitoring terminal may be a power distribution device with a monitoring function in a power network; the status signal may include any one or more of: the voltage, the current of the power network, the temperature, the humidity, the wind power level of the environment in which the transmission line is located, the load power of the distribution substation, the accumulated time of use of the equipment and transmission lines in the distribution substation, the location of the break or leakage or short circuit point of the power line. Those skilled in the art can also set the status signal collected by the power grid monitoring terminal according to actual needs.
The preset mode can be pre-registered with a plurality of signal coding models and corresponding relations between each signal coding model and the type of the status signal, and after the status signal is received, the power grid monitoring terminal can select the matched signal coding model according to the corresponding relations to generate a summary signal in a corresponding coding format. In an example, the number of the status signals and the time period for signal transmission may be further defined in the preset mode, so as to prevent the loss of the data packet.
In specific implementation, for the purpose of monitoring and controlling the power network, the power grid monitoring terminal may monitor a specific operation state between an equipment operation environment and a power network operation line, acquire a state signal, and generate a corresponding summary signal according to the state signal, where the summary signal may include one or more state signals of the power network, and may reflect a state of the power network in real time.
In practical applications, after the summary signal is generated, the summary signal may be sent to a cloud server. In an example, the power grid monitoring terminal may send the collected signal to the cloud server through the uplink timeslot, and certainly, other sending manners may also be adopted, and the specific sending manner may be determined according to a structure of the cloud server, which is not limited herein.
