All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The invention is described in further detail below with reference to the accompanying drawings:
referring to fig. 1 and 2, in an embodiment of the present invention, a power grid regulation and control panoramic transparent access method is provided, which is implemented by establishing a power grid regulation and control panoramic model, so as to integrate data models in a power grid regulation and control area, and perform power grid regulation and control panoramic transparent access based on the integrated data models, so as to implement that power grid regulation and control service-oriented panoramic information is available if necessary, improve the sharing capability of information resources between heterogeneous systems, and support power grid operation situation awareness and global cooperative control based on multidimensional information. Specifically, the power grid regulation panoramic transparent access method comprises the following steps.
S1: and acquiring a service model of the data access service, and determining source end data to be acquired according to the service model.
Specifically, it can be understood that the user inputs information, and the user determines and inputs a service model of the data access service based on the data access service in actual work. And then, determining source end data to be acquired according to the service model, wherein the source end data to be acquired refers to the source end data required in the service model, and taking the source end data as query request information to perform a power grid regulation and control panoramic transparent access request.
S2: and determining a source end object of the data to be accessed through a preset power grid regulation and control panoramic model according to the source end data to be acquired. The preset power grid regulation panoramic model is a set obtained after matching and mapping of each data model in a power grid regulation area, and based on the set, a data source end object to be accessed can be directly determined according to source end data to be acquired, wherein the data source end object to be accessed refers to a data source end object capable of providing the source end data to be acquired.
To implement S2, a power grid regulation panoramic model needs to be constructed first. Specifically, the embodiment provides the following power grid regulation panoramic model construction method.
Firstly, all service systems in a power grid regulation and control area are required to be abstracted into system objects as objects. In this embodiment, according to connection requirements and data extraction modes of different service systems, a service system is abstracted into three system objects, namely a data source end object, an application service object and an information management object. The connection requirement of the service system refers to a specification or a condition that the service system needs to follow when accessing external information. For example, the dispatching automation system is an open system, allows services or applications written by a third party to be registered in the system, and uses a bus of the system; for example, the power utilization system is relatively independent, service registration or data interfaces are not provided for the outside, interaction can be performed only through data files in a custom format, the connection requirements may not be technical, and may also be related to aspects such as management, service division and the like, and the connection requirements of the service system and the mode of providing data for the outside determine the degree of openness of the service system to the outside, so that a technical route and a functional module can be selected.
The data source end object is used as a basic data source end provider, can provide power grid operation data or equipment monitoring data required by power grid regulation and control service, and can be further subdivided into an open data object, a semi-closed data object and a fully-closed data object according to the external openness degree of the data source end object, and each type of data source end object needs to be capable of providing a data object range in the data source end object and providing an access and calling application function range. The data object range refers to that data models in different service systems are in a range, for example, the data model of a regulation and control system is mainly equipment with the voltage of more than 110kV, and the data model of a distribution network system is mainly equipment with the voltage of 110kV or less; the application function range is similar, for example, the regulation and control system has the power flow analysis and state estimation of the whole network, but the power flow analysis is not available in the distribution network system, because the model range in the system is very small, the method cannot be used.
The open data object is used as an open data source end system or node, software and functional modules meeting the safety requirement of the power system are allowed to be deployed in the open data object, a communication port required by corresponding application service can be opened, the node can provide complete service data access capability and application cooperative calling capability, and service information can be customized and expanded according to service application requirements. The semi-closed data object allows software and functional modules which meet the safety requirements of the power system to be deployed in the object system, but only information interaction can be carried out by using an information interaction function or interface specified in the semi-closed data object, and the nodes can use business data access and application collaborative calling through adaptation of the information interaction interface in the system. The totally-enclosed data object is used as a totally-enclosed data source end, software and function deployment cannot be carried out in the totally-enclosed data object, and only through a specific mode, such as a browser, a data terminal and the like, passively browse or receive information data provided by the node, the node cannot perform active service data access and application cooperation, data acquisition needs to be performed by adopting a data extraction and collection mode, therefore, it is necessary to have a corresponding data analysis and processing module for use with the type of data object, such as a dispatching automation system and a distribution network system, can be used as an open data object, the electric system is used as a totally closed data object, the electric system does not provide application service for the outside, only provides data files or a website for a browser to view, for such systems, only passive reception or extraction of data is possible, which has to be analyzed for the conversion of meaningless data into meaningful information.
The application service object is used as an application service provider, which can acquire information data from the data source end object to be used as an independent application analysis center to provide an application analysis result, and can also be used as an application function module to provide application service call or analysis processing of service data to the outside.
The information management object is an information manager, and can be divided into a data management object and an application management object according to the type of information to be managed. The data management object is used for receiving and managing model information of the data objects provided by each data source end object, and comprises attribute information of key word description, source end object description, data object state, data acquisition mode, data affiliated model and the like of the data objects, and the data management object can form an index list for all registered data objects. The application management object is used for receiving and managing service function interface description information which is externally provided by the data source end object and the application service object and can be accessed and called, and contains information such as service names, service addresses and ports, interface parameter definitions and service running states, and the application management object can monitor the running condition of the application service according to the service registration information and manage the running of the application service.
After the modeling process is completed, the data source end models of all the data source end objects in the power grid regulation and control area need to be obtained. Specifically, referring to fig. 3, in this embodiment, a digraph of a power grid regulation and control area is obtained, and a data source end model of all data source end objects in the power grid regulation and control area is obtained through traversal according to the direction of the digraph and by using a breadth traversal algorithm.
Specifically, the hierarchical division information of the current power grid regulation and control area is obtained, a plurality of data source end objects on the uppermost layer are used as root nodes, all data source end objects which can be reached by the current nodes are traversed from the root nodes according to the direction of the directed graph, and a source end object model of the traversed data source end objects is obtained, wherein the source end object model generally comprises attribute information of power grid equipment, measurement information of the equipment and the like. For example: a power grid model of a main dispatching system in a Jiangsu dispatching center is mainly power grid equipment with voltage of more than 110kV and is responsible for monitoring the operation of a power grid, and a distribution network system of Jiangsu is mainly power distribution equipment with voltage of less than 110 kV. And then, summarizing source end data sources which can be obtained by a current root node to form a data information range which can be obtained by the current level, continuously traversing sub-nodes of the next node level after the node traversal of the next level of the root node is completed, obtaining a source end object model of a traversed data source end object, finally constructing the topology of the whole system architecture by using all the data source end models, and simultaneously forming data and a data range which can be directly obtained by each node.
After all data source end models are acquired, in this embodiment, at least one of the following methods is used: the method comprises the steps of matching and collecting equipment objects in each data source end model in a power grid regulation and control area to obtain a power grid regulation and control panoramic model by a local topology generation method based on an object model splicing mode, a piecewise normalization minimum edit distance algorithm based on a power system naming rule and an autonomous identification method based on machine learning.
Specifically, referring to fig. 4, for a heterogeneous data source end model with a connection relationship, since the data source end model already has a complete topological connection relationship, for example, the association of devices is realized between power grid devices through a connection point number, a virtual terminal index number of a device in a substation, and the like, a local topology generation method based on an object model splicing manner may be adopted in a manner of setting a boundary connection device, and specifically, the heterogeneous data source end model is spliced by using the boundary device as a bridge to realize the primary matching of the heterogeneous data source end model, so as to form a complete data model of a power grid regulation and control region.
However, in practice, due to the large difference between the descriptions of the same device object of heterogeneous data source end models, not all data source end models can be spliced, for example: "east of China, east bridge/500 kV. east peak line/Qin bridge line 5012 switch" and "Jiangsu, east of China, east bridge substation/500 kV. east peak line/branch of a river bridge line 5012 switch", this is the name of the same switchgear in different data source end models, the power grid regulation and control panoramic model obtained through the splicing mode can't realize the unified description of the data source end model, and carry on the mapping and conversion of the apparatus object between two data source end models through the way of comparing manually and need consume the greater manpower cost, at this moment, adopt the minimum edit distance algorithm of sectional normalization based on naming rule of the electric power dispatching system in this implementation, match the name similarity to the apparatus object with greater name difference in the heterogeneous data source end model, realize the relatching of the heterogeneous data source end model, the algorithm realizes the procedure as follows:
and segmenting the names of the equipment objects in the heterogeneous data source end model according to the naming rules of the power dispatching system, and forming segmentation corresponding comparison according to the naming template rules. Then, the minimum edit distance calculation is carried out on each corresponding segment, and the dynamic programming equation is as follows:
wherein dp [ i ] [ j ] represents the edit distance of two character strings; i represents the character subscript of the character string A; j represents the character subscript of the character string B; str1[ ] represents the character value of the designated subscript position of the string A; str2[ ] indicates the character value of the designated subscript position of the character string B, and the minimum edit distance value in each segment is calculated, and assuming that the name length of the current device a segment k is m and the name length of the device B segment k is n, the minimum edit distance of the current segment is dp (k) ═ dp [ m ] [ n ].
After the minimum edit distance calculation of each segment is completed, the situation that the shorter names are different but the minimum edit distances are the same when the names are matched is considered, for example, the minimum edit distances of the east bridge substation and the east bridge substation are all 3, and the similarity between the east bridge substation and the east bridge substation is obviously higher, so that the normalization processing is adopted to shield edit distance deviation caused by the character string length difference, and the obtained similarity calculation formula between the two character strings is as follows:
wherein Sim (a, B) represents the similarity of character strings a and B; f. of i Representing the name character strings after segmentation, and the similarity weight between the segments; DP (i) represents the name character string after segmentation, and the edit distance between the segments; max (len (a), len (B)) represents the maximum value of the length of the character string a and the length of the character string B; k represents the number of character string segments. According to the formula, the similarity of all the segments can be integrated to obtain the similarity of the whole name character string, wherein the similarity weight of all the segments of the name can be formulated and adjusted according to naming rules among different power dispatching systems, and the device object with the highest similarity in the heterogeneous data source end model is matched.
In the above description, a power grid base model is constructed based on a known device model topology, a name similarity matching data set is constructed based on a device object name primary matching result, and for device objects which cannot be matched in the above manner, referring to fig. 5, a machine learning-based autonomous identification method is adopted to match and assemble the device objects in each data source end model in a power grid regulation and control region.
Specifically, before machine learning, a training data set needs to be established, based on matching and correlation results of data source end models obtained in the two modes, a training set for machine learning is established through analysis, extraction and training of characteristic information such as naming standards, similarity matching results, model electrical attributes, analog-to-digital mapping rule graph connection relations and historical measurement data of all system information models, an automatic identification model of heterogeneous data source end models on a mathematical level is formed through training of the training set, then unidentified data source end models serve as input, matching is conducted through the automatic identification model, and the purpose is to complete matching and mapping of most data source end models through automatic and programmed means, so that human intervention and naked eye identification are reduced.
And finally, combining a collection of the data source end models which are automatically identified, automatically forming information lists such as name mapping relations, full-topology connection relations and attribution distribution of discrete information among the heterogeneous data source end models, and constructing a power grid regulation and control panoramic model. The attribution distribution of the discrete information includes, for example, an information object list to which the non-device measurement information may belong, a terminal device list to which the electricity consumer may be mounted, and the like.
According to the construction method of the power grid regulation panoramic model, the power grid regulation panoramic model is obtained and preset, and then the equipment object of the source end data to be acquired is determined according to the name of the source end data to be acquired; determining a data source end model where the equipment object of the source end data to be acquired is located through a preset power grid regulation and control panoramic model based on the equipment object of the source end data to be acquired, and obtaining a data source end model to be accessed; and determining a source end object of the data to be accessed according to the source end model of the data to be accessed.
S3: and acquiring data service information of the data source end object to be accessed, accessing the data source end object to be accessed according to the data service information of the data source end object to be accessed, and acquiring source end data to be acquired.
Specifically, in this embodiment, first, according to the data source end object to be accessed, an access path of the data source end object to be accessed is obtained through a preset data source end object index topology, and then, according to the data source end object to be accessed, the data source end object to be accessed is accessed and the source end data to be obtained is obtained.
Specifically, referring to fig. 3 again, when traversing all data source end objects in the power grid regulation and control area according to the direction of the directed graph and by adopting a breadth traversal algorithm, weights among the data source end objects are set according to some experiences or actual situations in the field, and the data source end object index topology is obtained. For the fully-enclosed data object node, the node can only passively receive data, can be set to have a larger weight and point to the root node in a unidirectional way, and marks that the data of the node can be acquired and the data information can be updated only after the system actually runs. Say: the access path weight may be set to be lower, for example, to be 20, if the system crosses the wide area network but the communication bandwidth is larger, the access path weight may be set to be 30, and the priority local access principle may be adopted. Like the G node in fig. 3, this node is special and can only acquire data in one direction, so the path weight is set to be very large, set to 100, and if there are other ways to access the data of this G node with smaller path weight, then another way can be selected instead of selecting this path of G node- > E node.
In the embodiment, when the source data to be acquired is acquired, the source data to be acquired is acquired in a binary request response type, a binary subscription distributed type or a text type data exchange type manner. The binary request response formula is specifically as follows: acquiring and accessing information data of specified data by acquiring the definition of a binary service interface externally issued by a data source end object and format description information of exchange data of the binary service interface; the binary subscription and distribution specifically includes: setting a designated data range to a data source end object, and after subscribing data in the designated range, periodically publishing the data by the data source end according to the data range subscribed by a subscriber; the text type data exchange formula is specifically as follows: text files are used as carriers for data interaction, wherein keyword description of data and required measurement information and states are contained.
When a binary request response type or a binary subscription distribution type is adopted, in order to balance the universality and transmission efficiency requirements of a service interface on heterogeneous data information, a dynamic data interaction strategy based on protocol self-description is adopted for data interaction, so that different types of data members in the service access interaction process can be supported, the requested/responded data memory block can be efficiently analyzed, and the adaptability and transmission performance of information interaction are improved.
Regarding the implementation of communication construction of data interaction, in this embodiment, a cross-platform programming language is used to form a bottom information interaction module, and different instantiation processing methods are adopted according to a specific deployment environment, specifically, the following two methods are used: first, the interactive module is deployed independently. Specifically, the cross-platform codec function module, the communication client module, and the communication server module are used to perform network communication of information interaction in a service architecture, and a target system is required to be able to open a port corresponding to a service function. Second, deployment is based on existing communication environments. Specifically, when the existing communication environment in the target system, such as the existing message bus and service bus, is used to deploy the service architecture, an adaptation module and a protocol conversion module for the existing communication environment of the target system need to be added on the basis of the existing service function module, and format conversion is performed according to the communication requirement of the target system.
